Stainless steel grinding balls for mining / ball mill

Grinding balls for ball mill use are used in many areas of mining and industry to pulverise and grind. Grinding balls for mining are generally used to break down secondary materials such as rock, cement and stone during the extraction of ores and metals. AISI steel grinding balls for ball mill applications typically have a tolerance of ±0.05/±0.10 and a density of 7.70 to 7.95.

Wet Grid Ball Mill

Grid ball mill is widely used in smashing all kinds of ores and other materials, ore dressing and national economic departments like building and chemical industries etc. The size of ore shall not exceed 65mm and the best feed size is under 6mm. The effect in this job is better than coarse grinding.

Ball Mill an overview ScienceDirect Topics

2021-8-2  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.

Mill Charge an overview ScienceDirect Topics

Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.
