2.According to the particle size of the grinding material, the material is loaded into the cylinder by the hollow shaft of the wet grid ball mill feeding end. When the ball mill cylinder rotates, the grinding body acts on the cylinder liner due to the action of inertia and centrifugal force and friction. It is carried away by the cylinder.
validity of each theory within a certain particle size range. This study illustrated that Kicks law was applicable in the crushing range (above 1 cm in diameter) . Bond's theory was more suited to the particle size ranges involved in conventional ball and rod mill grinding (5 to 250 mm). Rittinger's law showed more _app1icability to the fine

The particle size distribution ratio (%) in the milled EoL FL for different ball sizes (0.4, 0.8, 1.5 or 5.0 mm in diameter), and at varying milling duration (1–8 h; interval, 1 h), were used to determine the ball diameter for further optimization experiments regarding the ball weight (50, 100, 200 or 300 g), and mill rotation speed (80, 120 ...
Mills should be sterilized by steam before use.Contamination of milled materials: In case of potent drugs and low dose products, contamination of the products should be avoided),the toughness and surface hardness of the solid, the roll speed, the milling time, the particle mixture and the size of milling ball.
Ball milling and ultrasonication were used to reduce the particle size and distribution. During ball milling the weight (grams) ratio of balls-to-clay particles was 100:2.5 and the milling operation was run for 24 hours. The effect of different types of balls on particle size reduction and narrowing particle size distribution was studied.

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
Ball mill and rod mill are suitable for different materials 1. Selection by material's hardness Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals. 2. Selection by required particle size
