Journal of Physics: Conference Series PAPER OPEN
Abstract In fine grinding of cement in a ball mill, it is sometimes impractical to grind finer in a dry state. Even though the chemical reactivity requires the material to be dry ground, it is sometimes necessary to use different breakage machines to ob tain the product, but it is usually more expensive, requires more energy and reduces capacity.

ATTRITORS AND BALL MILLS HOW THEY WORK Robert E
2021年2月4日 Ball mills work well on hard, brittle materials. They are not as suitable for grinding elastic, ductile or fibrous materials, or for fine grinding in general. Ball mills can blend and grind at the same time, yielding a fine, intimate mixture. Conventional ball mills are usually limited to a particle size of 1µ after one hour of grinding

Kinetics of fine wet grinding in a laboratory ball mill
2001年1月15日 An analysis of the kinetics of batch dry grinding in a laboratory ball mill has explained the results by introducing the concept of a slowing down factor, K [2], [3]. K is defined as the ratio of the specific rates of breakage at some high degree of grinding to the normal specific rates of breakage. This factor decreased when fine material ...

What Are the Differences between Dry and Wet Type Ball
2023年2月15日 The water can wash away the fine particles in time to avoid over-grinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
