INVESTIGATION OF EFFECTS OF GRINDING MEDIA SHAPES TO THE GRINDING EFFICIENCY IN BALL MILLS. with spherical balls for 30 minutes and after particle size analsys was made. Then mill
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
The resulting forces will cause particles to move depending on particle mass. Thus small particles are moved further than large particles. Furthermore, particle charge is a surface phenomena and the larger surface area of fine particles will tend to have a higher charge. These size effects can lead to separation by size rather than composition.
Experimental work has been carried out to study the effect of major operating variables, such as slurry solid mass fraction, grinding media size, density and pin tip velocity on the milling efficiency of silica. The effect of these major operating variables on the variation of width of product size distribution was studied using response

Effect of Particle Size Distribution on Grinding Rate in Dry Ball Milling. It has been shown above that: (i) the particle size distribution has a significant effect on the breakage rate of the particles, and (ii) intersize particle-particle interactions play an important role in determining the breakage kinetics.
The stone size of a metal or single phase alloy is an estimate of the average stone diameter, usually expressed in millimeters. The metallurgical techniques used to determine stone size are not necessary for this discussion, the major point to remember is that stone size is an important material characteristic.

Of course, the answer is ultimately feed efficiency, producing the most milk, eggs, meat or fiber at the lowest possible cost.
However, the cost of grinding increases and mill throughput decreases as particle size decreases (Table 1) . The costs of reducing particle size and the mill throughput have improved due to recent changes in the engineering design of grinders and their improved efficiency of particle size reduction.
