ball mills an overview sciencedirect topics

the ball mill method was first invented by shimadzu in japan in 1924. nowadays a great variety of mill designs are in use but the basic principles applied by shimadzu remains the same. the ball mill process is based on solid-phase reactions and operates within the temperature range between 70 and 180176;c.

the ball mill is used for grinding materials such as coalpigmentsand fedspar for pottery. grinding can be carried out in either wet or dry but the former is carried out at low speeds. the advantages of wet grinding are less power consumptionincreased capacityno dust formation etc dis advantages are high wear on the grinding medium and

identification of optimal mill operating parameters

sented by the bond f.c. (1960) test method. this method is widely used both for evaluating the grindability of a material and for determining the power required to drive the mill. however it uses data from laboratory tests while many empirical correction factors were proposed for the scale-up to larger mills or other operating conditions. with respect to the second group herbst j.a. and
