Batch Type Continuous Ball Mill 21t/h Ceramic Ball Mill Grinder

Large Ceramic Ball Mill / Mining Ball Mill Manufacturers in China

Introduction:

Ceramic ball mills are a type of ball mill and are used in the size reducing or milling of hard materials such as minerals, glass, advanced ceramics, minerals for ceramics and semiconductor materials down to 1 micron or less. The residence time in ceramic ball mills is long enough that all particles are given the same treatment and result in a narrow particle size distribution. The ceramic is 90%-96% aluminum oxide (alumina) brick, which is very hard (9 on the Mohs hardness scale) and will not contaminate most products. Ceramic ball mills are simple in design and consist of horizontal cylinder lined with 1.5” to 2” thick alumina brick. The slow rotating vessels is half filled alumina grinding media ¼” to 1.5” in diameter and as the vessel rotates and the media is lifted and cascades down, the particles are milled between the grinding media by the many impacts.

Ceramic ball mills have the advantage of being self-contained so operators are not exposed to the milled product. Ceramic ball mills can be used equally well for wet or dry grinding. In the case of wet grinding, the particles are also being dispersed in the liquid medium as the particles are reduced in size. Ceramic ball mills can be fully jacketed to maintain temperatures of heat sensitive products – through the liner is thick, alumina has a very high heat transfer coefficient. Ceramic ball mills scale up well and actually improve in performance with increasing diameter. Ceramic lined mills are available in sizes from laboratory scale (also called milling jars) as small as 0.1 usg to large 5,000 gallon mills. Other mills are available with liners made from made natural rubber or polyurethane.

Working Principle:

Ceramic ball mill is horizontal cylindrical rotation device, driven by brim gearwheel. There are two chambers and grid. Material goes into the first chamber through the feeding inlet. Inside the first chamber, there are stage liners and ripple liners as well as steel balls. The shell rotates so as to generate electricity, and this force brings ball to a certain height and then balls drop down by gravity, the impact is the grinding force to the material. After the primary grinding, materials go into the second chamber through segregate screen. In the second chamber, there are flat liners and steel ball, after the secondary grinding, material is discharged from the discharging.

Our Advantages:
Batch type ball mill (ceramic ball) is mainly used for mixing of the material, grinding, the fineness of the product is uniform, saving power. Both dry grinding, wet grinding can also be. The fineness of the grinding operation, relying on the polishing time control themselves.
1. It is suitable for mixing and milling of general and special materials. Users can choose the proper model, lining board and media as per the factors, such as: materials specific gravity and hardness, as well as output, etc.
2. It can be used for wet or dry grinding, finished slurry can pass 1000 mesh screen. The fineness of grinding material depending on milling time.
3. Lower investment, energy saved, novelty structure, easy and safe to operate, stable and reliable performance, etc.
4. Different liners and grinding media can be used to meet different requirements. Motor Auto decompression start to reduce the starting current, and its structure is divided into integral independent.
