【Overview of Cement Mill】

Cement mill is the key equipment for grinding after the crush process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics, and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.

 【Structure of Cement Mill】

Cement mill is composed of feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition. Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.

【International standard Cement Mill】

High efficiency Cement Mills grinds material by rotating a cylinder with ceramic grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to *0 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed".

【 Application of Cement Mill】

Cement mill are generally used to grind material 1/4 inch and finer, down to the particle size of *0 to *5 microns. To achieve a reasonable efficiency, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. It is widely used in building material, ceramic raw material, chemical industry, etc; it can be used both dry and wet.

 【Working Principle of Cement Mill】

The cement mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of ceramic ball in the chamber. The centrifugal force caused by rotation of barrel brings the ceramic ball to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.

【Features of Cement Mill】

1) An efficient tool for grinding many materials into fine powder.
2) Widely used in building material, and chemical industry.
3) Can be used both dry and wet.
4) As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours.
5) The longer the ceramic mill runs, the finer the powder will be.
6) Our ceramic mill have been used to grind glass, powder food products, create custom varnishes, make ceramic glaze, powder various chemicals.
