# wear rate of grinding ball mill in ball mill

### Ball Mill an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 510 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

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

### how to estimate the wear rate for Ball mill Page 1 of 10

Dec 08, 2009Re how to estimate the wear rate for Ball mill. Hey; Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated.

Ball Mill Design. Autogenous mills range up to 12 meters in diameter. The length to diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 11and 1.81. For fine regrinding in open circuit, the ratio ranges from 1.31 to 1.51.

### Mill (grinding)

SAG is an acronym for Semi Autogenous Grinding. SAG mills are autogenous mills but use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
