The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc as well as for ore dressing of both ferrous and non-ferrous metals

AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill

For overflow ball mills, the charge should not exceed 45% of the mill volume For grate discharge mills, the charge should occupy about 50% of the mill volume Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, ie,

SAG Mill Grinding Circuit Design


In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit As for any output, ball mill circuit output is a function of both its inputs and efficiencies There are two "inputs" to a ball mill circuit: the ore fed to the circuit
