Advanced Alumina Ceramic Balls more suitable for cement grinding .

In the cement grinding areas, "roller presser + ball mill" in double closed joint grinding process, has become the mainstream technology in domestic cement grinding system.

cement grinding.jpgSteel ball with density 7.8 g/cm3 is widely applied in cement grinding ,steel ball filled in ball mill causes heavy weight during grinding operation.which is the main reason for high electricity consumption.  wear resistant ceramic grinding media  density is generally 3.8 ~ 3.9g / cm3, density approximately reduced by half than steel ball. Half the density in a ball mill filling rate unchanged, the weight of grinding balls will be half. So it is bound to reduce the total weight, if the ball mill grinding efficiency remains unchanged, power consumption will be decreased.

Alumina ceramic balls is more suitable in cement grinding system for cost effective .chemshun ceramic balls is made from fine grinding micron size powder; rolling into ball shape and then sintered at high temperature.best feature is lower wear loss, 92% or 95% alumina content, sizes ranges from 13mm to 30mm. the physical properties compare with steel ball as followings:

Characteristics and applications of inert alumina ceramic balls

图片
   Inert alumina porcelain balls have the characteristics of high strength, high chemical stability and thermal stability. They can withstand high temperature, high pressure and corrosion from acids, alkalis, salts and various organic solvents. They are widely used in petroleum, chemical industry, fertilizers, natural gas and environmental protection industries. As a support and covering material for the catalyst in the reactor, it can buffer the impact of liquid and gas entering the reactor on the catalyst, protect the catalyst, and improve the distribution of liquid and gas in the reactor.       Inert alumina ceramic balls are used in industries such as environmental protection and environmental protection as covering support materials and tower packing for catalysts in reactors. Inert alumina ceramic balls have the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acids, alkalis a

Alumina Ceramic Dry Grinding Balls from China Manufacturer

图片
 Ceramic Dry grinding ball is a kind of grinding media, mainly used in equipment such as ball mills, stirring mills, peeling machines, polishing machines and sanding machines. This kind of grinding ball is made of imported calcined alumina powder, which is formed by cold isostatic pressing and then sintered at high temperature. It has high strength, high hardness, low wear and strong mechanical properties. In addition, dry grinding balls have the characteristics of low specific gravity, less than half of traditional steel balls, and are more energy-saving. Grinding balls can increase the volume ratio of the ball mill, improve grinding efficiency and save grinding time. Dry grinding balls are widely used for grinding materials in quartz sand, cement, copper ore, iron ore and other industries, and can be used for non-ferrous metal ores, industrial ceramic powder materials, metal powder materials, titanium dioxide, paper making, coatings, inks , other powder materials and other fields.
