Breakage rates of particles in a ball mill change with instantaneous particle size distribution in the mill Slurry density and the presence of a grinding aid also affect breakage rates to min 1 in 5 min for natural size feed whereas the rate stayed around min 1 Factors Affecting Breakage Rates in Batch Grinding

However the mill is typically not suited to reducing materials to su perfine submicron particles which requires wet grinding 1 The dry attri tion mill also generates more internal heat than a wet mill and can require running a refrigerated coolant through the mill s cooling jacket Ad justing the mill s material to media

Introduction Due to higher energy efficiency and the ability to produce the extremely fine size of the product stirred media mills are frequently used to grind fine or ultra fine particles in many industrial applications such as pharmaceutical cosmetic paints and paper manufacture

· The particle sizes that can be fed to a ball mill depend on the ball size distribution of the charge and more specifically the diameter of the make up ball This is also a function of the tenacity of the particles as this controls the size at which the selection function is maximum for a given ball charge Particles that are larger than
