Size Reduction Mill Application and Design
Steel ball mills and ceramic lined mills are used the size reduction of hard materials such as minerals, glass, advanced ceramics, metal oxides and semiconductor materials down to 1 micron or less. The residence time in size reduction mills is long enough that all particles get consistent treatment, which also provides a narrow particle size distribution.
Size reduction mills are simple in design and consist of horizontal rotating vessels half filled with grinding media. The particles to be milled are trapped between the grinding media or balls and are reduced in size by the impacts. Size reduction mills have the advantage of being self-contained so operators are not exposed to the product being milled. Ball mills can be used equally well for wet or dry grinding. In the case of wet grinding the particles are also dispersed in the liquid medium.
Size reduction mills may be jacketed to reduce the milling temperature of product that are that sensitive. Ball mills are available in sizes from laboratory scale (also called milling jars) as small as 0.1 usg to 5,000 gallon mills. Ball mills are available with product contact surfaces to accommodate contamination or wear requirements. The liner materials include AR 400 high-chrome abrasion resistant steel, high-alumina ceramic brick, natural rubber lining and polyurethane linings.
