青岛维晶工业有限公司2021年成立于青岛市城阳区。其前身为青岛地平线矿山机械有限公
司、青岛城阳区地平线新型材料厂及鄂尔多斯市维晶商贸有限公司。是一家提供解决节能降
耗、增产增效方案及产品研发、销售为一体的公司。企业创立初期主要生产销售旋流器、耐磨
管道、选矿药剂等产品，并在国内首次引入内衬微晶复合陶瓷耐磨材料的理念，极大地提高了
设备的耐磨性能。
首台整体烧结的碳化硅陶瓷旋流器于2007年在内蒙古彤力矿业公司使用，至今主体设备依
然正常运转无损耗。公司生产的内衬特种陶瓷系列产品以其耐磨损、耐腐蚀、耐高温的特点被
包钢集团、中海油集团、云天化集团、中化十六建、紫金集团、唐山三友化工等企业广泛应用
于高损耗的特殊部位，均有不俗表现。
公司于2013年引入冷等静压、微粉注浆以及凝胶注模等先进的生产工艺，生产出密度不低
于3.36g/cm3的高强度特种陶瓷制品，达到了世界领先水平。2019年，我公司在超细微粉高固
含量胶态成型料浆制备领域又取得了巨大的突破。几十年以来，超细微粉高固含量胶态成型料
浆制备技术或者说超细微粉的分散技术，一直是困扰全球科研人员的一个世界级难题。我公司
经过十几年的摸索、积累与实验，取得了巨大的突破，已经完成与世界五百强企业以及部分国
内尖端企业产品的比对。比对结果显示我公司产品的流变、触变、悬浮稳定性等性能方面已经

特种陶瓷是由人工合成的原料制成的，陶瓷粉料的性能在很大程度上决定了陶瓷的质量，所以各
国对陶瓷粉料的研究、开发和制备十分重视，发达国家各种高纯超细的粉料，成分控制的特种陶瓷粉料
都有专业的公司生产，规格齐全、质量稳定。我国对陶瓷粉料的制备还未引起足够的重视，我国有许多
特种陶瓷的粉料尚无专业化生产企业，许多企业为了制备高性能陶瓷材料，不得不高价采购国外进口的
高质量粉体，从而造成了市场上高性能陶瓷制品价格高昂，限制了高性能陶瓷材料的发展与应用。
Special ceramics are made of synthetic raw materials. The performance of ceramic powder largely determines the
quality of ceramics. Therefore, countries attach great importance to the research, development and preparation of ceramic
powder. All kinds of high-purity and ultra-fine powders and special ceramic powders with controlled composition in developed
countries are produced by professional companies with complete specifications and stable quality. China has not paid enough
attention to the preparation of ceramic powder. There are no specialized production enterprises for the powder of many
special ceramics in China. In order to prepare high-performance ceramic materials, many enterprises have to purchase
high-quality powder imported from abroad at a high price, resulting in the high price of high-performance ceramic products
in the market, which limits the development and application of high-performance ceramic materials.

通常情况下，材料的微观结构往往会对材料的宏观性能有着极大的影响。陶瓷材料是晶粒和晶
间组成的烧结体，其显微结构往往决定着其宏观性能。有许多研究表明，材料的耐磨性能与晶粒的
大小、晶界相的组成、晶界上的应力分布、气孔等等显微结构有着极大的联系。在工业上，特种材
料可以通过晶粒细化的方式来使其力学性能提高，这就是所谓的细晶强化。其原理主要在于晶粒的
粒径越小，晶界的面积也就越大，晶界的分布也就会越曲折，可以有效的增加裂纹扩展的路径，有
利于分散材料内部的应力集中现象。通过研究发现，晶粒细化对陶瓷材料的耐磨性能有着巨大的影
响。其次，气孔对陶瓷性能也有着很大的影响，在陶瓷材料内部，气孔相当于一种缺陷的存在，它
会造成应力的集中，加速裂纹的扩展，降低晶粒之间的结合强度，严重影响陶瓷制品的力学性能。
在摩擦力的作用下，气孔之间可能会彼此连接起来形成裂纹源，加速材料的磨损。陶瓷是由晶粒、
晶界相、和气孔等组成，在烧结过程中，加入到陶瓷中的一些添加剂和一些杂质成分主要以第二相
或玻璃相的形式存在于晶界上，他们的存在会对晶粒之间的结合强度造成一定的影响。这种影响可
以向优劣两个方向发展。技术的进步能够让第二相或者次晶相向着有利的方向发展，能使其具有
“钉扎作用”，让其能够精确地控制晶粒尺寸的生长和发育，并且增加这种微晶复合陶瓷的断裂韧
性，使其在摩擦磨损的过程中，裂纹能够穿晶断裂，避免裂纹沿着晶界结合强度较低处断裂引起整
体晶粒拔出而造成的严重磨损。
维晶工业采用自主技术生产，技术力量雄厚，生产工

In general, the microstructure of materials often has a great impact on the macro properties of materials. Ceramic
material is a sintered body composed of grain and intergranular, and its microstructure often determines its macroscopic
properties. Many studies have shown that the wear resistance of materials is closely related to the grain size, the composition
of grain boundary phase, the stress distribution on the grain boundary, the porosity and other microstructure. In industry,
special materials can improve their mechanical properties by means of grain refinement, which is called fine grain
strengthening. The principle is that the smaller the grain size is, the larger the area of grain boundary will be,
and the distribution of grain boundary will be more tortuous, which can effectively increase the path of crack propagation
and help to disperse the stress concentration in the material. It is found that the grain refinement has a great influence
on the wear resistance of ceramic materials. Secondly, pores also have a great influence on the properties of ceramics.
In ceramic materials, pores are equivalent to the existence of defects, which can cause stress concentration, accelerate
crack propagation, reduce the bond strength between grains, and seriously affect the mechanical properties of ceramic
products. Under the action of friction, the pores may be connected with each other to form a crack source and accelerate
the wear of the material. Ceramics are composed of grains, grain boundary phases and pores. In the sintering process, some
additives and impurities added to ceramics mainly exist in the form of second phase or glass phase on the grain boundary.
Their existence will have a certain impact on the bonding strength between grains. This kind of influence can develop in
two directions. The progress of technology can make the second phase or the secondary phase develop in a favorable
direction, which can make it have \"pinning effect\", so that it can accurately control the growth and development of grain
size, and increase the fracture toughness of this kind of microcrystalline composite ceramics, so that in the process of
friction and wear, the cracks can be transgranular fracture, and avoid the fracture along the grain boundary where the
bonding strength is low Serious wear caused by pulling out the whole grain.
Weijing industry adopts independent technology production, strong
technical force, advanced production technology and testing means, with
many famous advanced ceramic material research experts at home and
abroad and a group of experienced engineering and technical personnel.
The company has mastered cold isostatic pressing, micro powder injection,
gel casting, dry pressing and other molding technologies, and can
customize all kinds of precision structural parts such as ceramic
composite ceramic plungers, shaft sleeves, substrates, patches, pipes,
elbow, three links, and swirler. And established an effective quality
assurance system, committed to providing domestic and foreign customers
with wear resistance, corrosion resistance, high temperature and other
industries of ceramic application solutions.

微晶复合陶瓷在工业管道上的应用
Application of microcrystalline composite ceramics in industrial pipeline
工业管道的磨损一直是影响安全文明生产的一个
因素，随着科学技术不断发展，材料也不断创新，相
继出现铸石、铸钢、合金、离心浇注复合陶瓷等材
料。其中管道内衬氧化铝耐磨陶瓷以其高耐磨性、高
硬度、耐氧化、耐腐蚀性好和极高的耐高低温强度性
能,已成为一种应用最广泛的耐磨材料。
The wear of industrial pipeline has always been a factor
affecting safe and civilized production. With the continuous
development of science and technology and the continuous
innovation of materials, there have been cast stone, cast steel,
alloy, centrifugal casting composite ceramics and other materials.
Among them, pipeline lined alumina wear-resistant ceramics has
become the most widely used wear-resistant material because of
its high wear resistance, high hardness, oxidation resistance,
corrosion resistance and high high and low temperature
strength.
耐磨管道从采用内衬耐磨陶瓷衬板以来，国内外
致力于该项目生产和研究已达数十年，目前陶瓷管道
等各类产品的各项性能参数指标已趋于完善和成熟。
产品已在火电、钢铁、冶炼、水泥、机械、煤炭、矿
山、化工、港口码头等磨损严重的行业得到广泛应
用。在国外，工业企业普遍采用耐磨陶瓷做防磨内
衬，大部分国外进口设备都采用这种耐磨弯头。
Since the wear-resistant pipeline was lined with
wear-resistant ceramic lining plate, it has been committed
to the production and research of the project at home and
abroad for decades. At present, the performance parameters
of various products such as ceramic pipeline have tended to
be perfect and mature. The products have been widely used in
industries with serious wear and tear, such as thermal power,
steel, smelting, cement, machinery, coal, mining, chemical
industry, port and wharf. In foreign countries, industrial
enterprises generally use wear-resistant ceramics as
wear-resistant lining, and most foreign imported equipment
use this kind of wear-resistant elbow.
近年来随着我国电力、钢铁、水泥、冶金、
石化等行业建设的加速发展和新技术新材料的
不断推广，维晶工业生产制造的微晶复合陶瓷
管道和弯头已得到广泛的应用，管道和弯头出

In recent years, with the rapid development of
electric power, iron and steel, cement, metallurgy,
petrochemical and other industries and the continuous
promotion of new technology and new materials in China,
the microcrystalline composite ceramic pipes and elbows

微晶复合陶瓷管道、弯头与传统管道、弯头的比较
Comparison of microcrystalline composite ceramic pipe and elbow with traditional pipe and elbow
微晶复合陶瓷管道、弯头能在市场上不断取代一些传统的防磨材料，根本原因在于其优异
的产品性能，以及在与传统防磨材料如铸石、铸钢、离心浇注陶瓷材料（SHS自蔓燃陶瓷复合
管）及高铝陶瓷复合管相比所具有的多方面优势。
Microcrystalline composite ceramic pipes and elbows can constantly replace some traditional anti-wear
materials in the market. The fundamental reason is that they have excellent product performance and many advantages
compared with traditional anti-wear materials such as cast stone, cast steel, centrifugal casting ceramic materials
(SHS self propagating ceramic composite pipes) and high aluminum ceramic composite pipes.
(一) 性能比较 Performance comparison
1. 铸石 Cast stone
以前工业企业的弯头大部分都是使用铸石弯头，这种材料的特点是易碎、易开裂，而
且磨损面背包，壁厚25-35mm，有的竟然超过40mm，内侧短时间磨破开裂后，输送的粉体随
着缝隙向外侧磨损，其寿命也就只有一个大修期。而且内部常有气孔，易留隐患，一旦磨
穿，现场无法修补。
In the past, most elbows in industrial enterprises used cast stone elbows. This material is characterized
by fragile and easy to crack, and the wear surface is knapsack with a wall thickness of 25-35mm. Some even
exceed 40mm. After the inner side is worn and cracked for a short time, the transported powder is worn
outward with the gap, and its service life is only one overhaul period. Moreover, there are often pores
inside, which is easy to leave hidden dangers. Once worn out, it cannot be repaired on site.
2. 铸钢 Cast steel
铸钢（包括合金钢）广泛应用在防磨领域，其制造工艺相对简单。但由于材料本身性
能的局限和工艺的限制，铸钢材料的表面硬度（约60）远低于微晶复合陶瓷（80以上），
耐磨性能仅相当于微晶复合陶瓷的几百分之一至更低，用其制造的弯头在高磨损部位有投
运一个多月就磨穿的情况。此外，铸钢管道厚度大，非常笨重，且含碳量高，可焊性比较
差，需现场对焊缝热处理，给现场的安装维修带来相当大的困难。
Cast steel (including alloy steel) is widely used in the field of anti-wear, and its manufacturing
process is relatively simple. However, due to the limitation of the material properties and the limitation
of technology, the surface hardness of cast steel (about 60) is far lower than that of microcrystalline
composite ceramics (over 80), and the wear resistance is only one hundred to lower than that of microcrystalline composite ceramics. The elbow made by the steel casting has been worn through for more than one
month in the high wear parts. In addition, the cast steel pipe is thick, very heavy, and has high carbon
content and poor weldability. It needs heat treatment of welding seam on site, which brings considerable
difficulties to the installation and maintenance on site.

10 3. 离心浇注复合陶瓷管（SHS自蔓燃陶瓷复合管）
该工艺采用自蔓延离心浇注方法成型，主要利用物质自身化学反应，放热燃烧产生高
温，在燃烧波蔓延过程中合成新物质的技术。此种方法成型的陶瓷复合管内表面置换出陶
瓷层，与碳钢、锰钢钢管相比，耐磨性能有一定程度的提高，但是由于反应的温度不高
（平均不超过1200℃），反应时间短，还原出来的氧化铝还停留在低温相β- Al2
O3
，并没
有能够转换为高温相α- Al2
O3
（转变温度超过1300℃）。同是氧化铝，但是高温相氧化铝
与低温相氧化铝之间在强度、硬度及密度等性能上有着天壤之别。由于反应时间短，低温
相氧化铝与铁水离心分离不彻底，造成陶瓷层不致密、颗粒松散、硬度低。微晶复合陶瓷
弯头衬贴微晶复合陶瓷块或者整体成型并烧结的弯头，烧结温度高达1500℃，确保材料品
质。从实际防磨的效果来看，微晶复合陶瓷弯头的耐用时间是复合陶瓷弯管的20倍以上。
而且离心浇注复合陶瓷管的技术决定了不适合做弯头及大小头，普通技术条件下，复合陶
瓷管只能做成直管状，要做成弯管或大小头，必须将直管分割成若干段焊接，成型后的弯
头及大小头内壁不是流线型结构，妨碍物料输送，降低设备出力。同时，该种工艺所生产
的陶瓷复合管，微观裂纹多，质脆易碎，容易局部脱落失效，而且脱落后无法修补。
此外，从整个锅炉的吊架承载力来说，铸钢弯头、复合陶瓷弯头都是以重量和厚度来
取胜，有的弯头磨损面壁厚达40多毫米，从机组设计看，无疑给吊架增加重量，缩短了使
用寿命。
The process uses the self propagating centrifugal casting method, mainly uses the chemical reaction
of the material itself, exothermic combustion to produce high temperature, and the new material is synthesized
in the process of combustion wave propagation. Compared with carbon steel and manganese steel pipes, the
wear resistance of the ceramic composite pipe formed by this method is improved to a certain extent. However,
due to the low reaction temperature (no more than 1200 ℃) and short reaction time, the reduced alumina
still stays in the low-temperature phase β - Al2
O3
and can not be converted into high-temperature phase
α- Al2
O3
(transition temperature over 1300 ℃). However, there are great differences in strength,
hardness and density between high temperature phase alumina and low temperature phase alumina. Due
to the short reaction time and incomplete centrifugal separation of low temperature phase alumina and hot
metal, the ceramic layer is not dense, the particles are loose and the hardness is low. Microcrystalline
composite ceramic elbows are lined with microcrystalline composite ceramic blocks or integrally formed and
sintered elbows. The sintering temperature is up to 1500 ℃ to ensure the quality of materials. From the
actual anti-wear effect, the durability time of microcrystalline composite ceramic elbow is more than 20 times
that of composite ceramic elbow. Moreover, the technology of centrifugal casting composite ceramic pipe
determines that it is not suitable for elbow and reducer. Under ordinary technical conditions, composite
ceramic pipe can only be made into straight pipe. To make elbow or reducer, straight pipe must be divided
into several sections for welding. The inner wall of formed elbow and reducer is not streamline structure,
which hinders material transportation and reduces equipment output. At the same time, the ceramic composite
pipe produced by this process has many micro cracks, is brittle and fragile, is easy to fall off and fail,
and can not be repaired after falling off.

4.高铝陶瓷 High aluminum ceramics
高铝陶瓷是以氧化铝为主要原料而制备的一种高性能陶瓷，以其耐高温、抗氧化、耐
磨损、绝缘性好等优良性能，成为当今世界上应用最广的陶瓷材料之一。但是、目前我国
高铝陶瓷生产与应用存在的问题很多，突出表现在生产过程中，铝含量在88%—93%之间的
高铝陶瓷工业性能还比较好，铝含量大于93%的高铝陶瓷机械性能并不好，而铝含量在95%
以上的高铝陶瓷在很多情况下显示的不是耐磨性能，而是耐火性能。而且烧成温度随着铝
含量的上升却大幅度增加，成本也大幅度增加，产量却不高。因此，烧结温度过高、生产
周期长、能耗过大及产品成本提高而质量反而下降等现象一直困扰着高铝陶瓷的工业化、
规模化生产。微晶复合陶瓷与高铝陶瓷相比，由于选用了高分散性能的亚微米级原材料和
精细化的处理工艺，最终的烧结制品的平均晶粒尺寸能够精确的控制在2μm以内，平均晶
粒尺寸比高铝陶瓷低一个数量级，使得微晶复合陶瓷的耐磨性能远远优于高铝陶瓷。
High alumina ceramic is a kind of high-performance ceramic made from alumina. It has become one of
the most widely used ceramic materials in the world because of its excellent properties such as high
temperature resistance, oxidation resistance, wear resistance and good insulation. However, at present,
there are many problems in the production and application of high alumina ceramics in China. The outstanding
performance is that in the production process, the industrial performance of high alumina ceramics with
88% - 93% aluminum content is still relatively good, the mechanical performance of high alumina ceramics
with 93% aluminum content is not good, and the high alumina ceramics with 95% aluminum content in many cases
show not wear resistance, but fire resistance. Moreover, with the increase of aluminum content, the sintering
temperature increases greatly, the cost also increases greatly, but the output is not high. Therefore, high
sintering temperature, long production cycle, high energy consumption and high product cost but low quality
have been perplexing the industrialization and large-scale production of high alumina ceramics. Compared
with high alumina ceramics, the average grain size of the final sintered products can be accurately controlled
within 2 μ m, which is one order of magnitude lower than that of high alumina ceramics due to the selection
of high dispersion sub micron raw materials and fine processing technology. The wear resistance of the
micro crystalline composite ceramics is far better than that of high alumina ceramics.

12 At present, the price of elbow in the market is about 18000 yuan per ton for alloy, 13000 yuan per ton
for cast stone elbow and 17000 yuan per ton for centrifugal casting composite elbow (SHS self propagating
ceramic composite elbow). These kinds of elbows are particularly heavy. They make profits by weight. In other
words, the price of an alloy elbow is twice that of a microcrystalline composite ceramic elbow. With the money
of an alloy elbow, you can buy two microcrystalline composite ceramic elbows. The service life of the
microcrystalline composite ceramic elbow is more than 20 times that of the alloy elbow. Compared with the
service life and price, the microcrystalline composite ceramic elbow is more than 50 times that of the alloy
elbow.
(二) 价格比较 Price comparison
目前市场弯头的价格是：合金每吨1.8万元左右，铸石弯头每吨1.3万元，离
心浇注复合弯头（SHS自蔓燃陶瓷复合弯头）每吨1.7万元。这几类弯头特别重，
它们是以重量来谋利润。也就是说，一个合金弯头的价格是微晶复合陶瓷弯头的
两倍，用一个合金弯头的钱，可以买两个微晶复合陶瓷弯头，微晶复合陶瓷弯头
的使用寿命是这种合金弯头的20倍以上，用使用寿命与价格比，微晶复合陶瓷
弯头是合金弯头的50倍以上。
Example 1: the powder feeding pipe of 2 × 600MW
supercritical unit has a diameter of 530 × 10 and a 90 °
elbow with a bending radius of 1700mm. Cast steel elbow or
bimetallic composite elbow is used with a weight of 1700kg
and the total weight of all elbows (2 furnaces) is about
500-600t; while microcrystalline composite ceramic
wear-resistant elbow is used with a weight of about 450kg
and the total weight of all elbows (2 furnaces) is about
110kg Through comparison, it can be seen that the most
direct reason for using wear-resistant ceramic elbow with
ceramic lining is to reduce the weight of elbow greatly
and save at least 2 million yuan in investment (the unit
price of cast steel elbow or bimetal composite elbow is
12000 yuan / ton), not including the economic benefits
brought by the reduction of load of civil frame beam in
coal bunker due to weight reduction and the savings of
support and hanger materials The economic benefits in the
future. According to the service life, it can save tens of
millions or even hundreds of millions of yuan of maintenance
and replacement costs for many years at one time.
例1：2×600MW超临界机组送粉管道，管径为φ530×10，一个90°弯头，弯
曲半径R=1700mm，采用铸钢弯头或双金属复合弯头，重量为W=1700kg，全部弯头
总重（2台炉）约为500～600吨；而采用内衬微晶复合陶瓷片耐磨弯头，其重量
仅为W=450kg左右，全部弯头总重（2台炉）约为110～130吨；对比可看出，采
用内衬陶瓷片耐磨陶瓷弯头，最直接的是使弯头重量大幅下降，投资至少节约
200万以上（铸钢弯头或双金属复合弯头单价按1.2万元/每吨），还不包括重量
下降使得煤仓间土建构架梁荷载的降低所带来的经济效益，以及支吊架材料的节
省所带来的经济效益。按照使用周期来计算，可以一次性节省多年的维修、更换
费用数千万元甚至数亿元。

Example 2: comparison between microcrystalline composite ceramics and high alumina ceramics. 95
ceramic pieces with the same size and 20mm thickness are compared with the microcrystalline composite
ceramic sheets with 219 pipe lining. The weight of 95% high aluminum ceramic sheet is 12 kg, while the
weight of microcrystalline composite ceramic sheet is 11kg, and the weight of ceramic composite ceramic has
8.3% weight advantage; in price, the price of 95 ceramic sheet is about 20000 yuan per ton, and the price
of microcrystalline composite ceramic sheet is about 15000 yuan per ton, and the price of microcrystalline
composite ceramic sheet has 25% advantage; in terms of wear resistance, microcrystalline composite ceramic
is of 25% advantage in price; in terms of wear resistance, microcrystalline composite ceramic is of great
importance The wear resistance of the ceramic is 2-3 times of the best 95% high aluminum ceramics in the
market; therefore, the comprehensive cost performance of the ceramic composite ceramics is more than five
times that of the 95% high aluminum ceramics sold in the market.
例2：微晶复合陶瓷与高铝陶瓷之间的比较。以单位长度219管道内衬同等规
格20mm厚的95瓷片和微晶复合陶瓷片作比较。95%高铝陶瓷片的重量为12公斤，
而微晶复合陶瓷片的重量为11公斤，在重量上微晶复合陶瓷具有8.3%的重量优势；
在价格上95陶瓷片的价格约为2万元每吨，微晶复合陶瓷片的价格约为1.5万元每
吨，微晶复合陶瓷片在价格上就有25%的优势；在耐磨性能上，微晶复合陶瓷的
耐磨性能是市场上最好95%高铝陶瓷的2—3倍;因此，微晶复合陶瓷的综合性价比
是市售最好95%高铝陶瓷的五倍以上。
Example 3: compare with the price of common cold rolled steel. The proportion of steel is 7.85 g/cm3
,
and the market price is 5000 yuan / ton; while the proportion of microcrystalline composite ceramics is
about 3.38 g/cm3
, the weight per unit volume or unit area is only 43% of the steel weight. The cost of
ceramic ceramic for unit area is only slightly higher than that of steel, but its wear resistance is
thousands of times of steel, so the comprehensive cost performance is self-evident!
例3：与普通冷轧钢材价格比较。钢材的比重为7.85 g/cm3
，市场价格为
5000元/吨；而微晶复合陶瓷的比重约为3.38 g/cm3
，单位体积或者单位面积重
量仅为钢材重量的43%，铺单位面积的微晶复合陶瓷成本仅仅比钢材成本略高，但
其耐磨性能是钢材的数千倍，综合性价比不言而喻！
From the comparison of performance and price, it can be seen that microcrystalline composite
ceramics are the most cost-effective in terms of initial investment and operation cost.

18 QINGDAO WEIJING INDUSTRY CO., LTD. Application of microcrystalline composite ceramics in Hydrocyclone
微晶复合陶瓷在水力旋流器上的应用
水力旋流器是利用离心力场分离两相流体的高效分离设备，它依靠离心沉降进行分离，
将需要分离的两相混合液以一定的压力从旋流器圆筒段上部的进料口以切线或者渐开线的方
式送入，从而在旋流器内部形成强烈的旋转运动。由于两相之间的密度差异，导致颗粒之间
所受的离心力和流体曳力的大小不同，使得大部分轻相（或细粒级）通过旋流器溢流管排
出，而重相（或粗粒级）则由底流口排出。
Hydrocyclone is an efficient separation equipment which uses centrifugal force field to separate two-phase fluid. It
depends on centrifugal settlement to separate the two-phase mixture which needs to be separated and sent to the feed port
at the upper part of the cyclone cylinder by tangent or involute way at a certain pressure, thus forming a strong
rotational movement inside the hydrocyclone. Due to the difference of density between the two phases, the centrifugal force
and the fluid drag force between particles are different, which makes most light phase (or fine-grained) be discharged
through the overflow pipe of hydrocyclone, while the heavy phase (or coarse particle level) is discharged from the bottom
flow port.
旋流器广泛应用于黑色、有色、非金属矿山、化工、石油等选别或分离领域；常用于球
磨机闭路磨矿系统、矿浆的浓缩与脱水、微细颗粒的分级、回收、脱泥、尾矿充填与筑坝等
工艺中。为了适用于各种不同工艺条件，我公司可依据实际情况设计和制作各种不同规格的
旋流器。我公司生产的各种规格旋流器均采用微晶复合陶瓷作为内衬材料，大大的提高了旋
流器的使用寿命（一般情况下，其耐磨性能是聚氨酯材料、橡胶材料、高铝陶瓷、高铬合金
的五倍以上），使得旋流器的整体工作时间增长，维护次数减少，极大地保证了生产工艺的
稳定性，同时减少了后期维护的成本。
Hydrocyclone is widely used in black, non-ferrous, non-metallic mines, chemical industry, petroleum and other separation
or separation fields; it is commonly used in ball mill closed-circuit grinding system, pulp concentration and dehydration,
fine particle classification, recovery, desliming, tailings filling and damming and other processes. In order to adapt to
various process conditions, our company can design and manufacture various hydrocyclones of different specifications
according to the actual situation. Various specifications of hydrocyclones produced by our company use microcrystalline
composite ceramics as lining materials, which greatly improves the service life of hydrocyclones (generally, its wear
resistance is more than five times that of polyurethane materials, rubber materials, high aluminum ceramics and high chromium
alloys), increases the overall working time of hydrocyclones, reduces the maintenance times, and greatly ensures the quality
of production process Stability, while reducing the cost of later maintenance

24 QINGDAO WEIJING INDUSTRY CO., LTD. 目前维晶工业推出两款新型高效的选矿药剂。一种是针对反浮选铁矿、钨矿、磷矿、铝土矿与
萤石矿的WJ-1型选矿药剂。这款药剂与传统捕收剂相比，药剂的选择性能更好，精矿品位提升幅度
大，回收率高，药剂用量极小（仅40-100g/吨）。属于常温药剂，一般浮选药剂适用温度都在35°
左右，而WJ-1型捕收剂在20°就能达到最佳性能，减少能耗成本，能为企业带来良好的经济和社会
效益。另一种是针对难选硫化矿研发的新型活化剂WJ-2。与传统活化剂相比，这种活化剂对磁黄铁
矿的选择性活化效果极好，磁黄铁矿被活化后的表面电位高，非常容易被黄药类捕收剂吸附，可以
大幅度的提升精矿品位和回收率，同时浮选温度可以降低到常温。WJ-2活化剂对磁黄铁矿、难选金
矿、难选铅锌矿、难选铜矿等都具有良好的活化效果，尤其是解决了磁黄铁矿脱硫这一国际难题。
现向全国各个选矿科研机构、矿山企业免费派送药剂样品，推广这两种带来技术革新的新药剂。
At present, Weijing industry has launched two new and efficient beneficiation agents. One is WJ-1 beneficiation
agent for reverse flotation of iron ore, tungsten ore, phosphate ore, bauxite and fluorite. Compared with the traditional
collector, this agent has better selection performance, large increase in concentrate grade and high recovery rate, Minimal
dosage (only 40-100g / T). It belongs to normal temperature reagent. Generally, the applicable temperature of flotation
reagent is about 35 °, while WJ-1 collector can achieve the best performance at 20 °, reduce energy consumption and cost,
and bring good economic and social benefits to the enterprise. The other is a new activator wj-2 developed for refractory
sulfide ores. Compared with traditional activators, this activator is more suitable for pyrrhotite The activation effect
is excellent. The surface potential of pyrrhotite after activation is high, which is very easy to be adsorbed by xanthate
collectors, which can greatly improve the concentrate grade and recovery, and the flotation temperature can be reduced to
room temperature. Wj-2 activator has good activation effect on pyrrhotite, refractory gold ore, Refractory Lead-Zinc Ore
and refractory copper ore, especially solving the international problem of pyrrhotite desulfurization. We are now sending
reagent samples free of charge to various beneficiation scientific research institutions and mining enterprises across the
country to promote these two new reagents that bring technological innovation.
