Variables In Ball Mill Operation Paul O Abbe 174
the first problem will ball mills is that we cannot see what is occurring in the mill. the other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results. In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time.the laboratory scale ball mill is mainly used for various grind able materials dry or wet type in chemical, pharmaceuticals, herbals and catalyst industries for super fine micron size grinding. shree bhagwati mechtech pvt. ltd. laboratory scale ball mill is made from all the contact parts in s.s.316 & non contact parts in s.s. 304.the retsch is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application. the high energy ball mill max and MM 500 were developed for grinding with the highest energy input. the innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming
