Mill Steel Ball For Ore

AMIT 135: Lesson 7 Ball Mills & Circuits –

Recognize important considerations in ball mill selection. Reading & Lecture. In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill.

The ore is then ground in rod and ball mills. The slurry may also be ground in autogenous mills (a mill where the ore acts as the grinding medium) or semi-autogenous mills (steel balls are added to the ore). Hydrocyclones are used between each grinding step to separate coarse and fine particles.

Grinding Mills and Their Types – IspatGuru

09.04.2015· The mill consists of a cylindrical drum, sometimes tapered at one end, and usually has a charge of steel balls (up to 40 % by volume) ranging in size up to 125 mm for larger mills. Product size can be as small as 0.005 mm, but product size is dependent upon the time the charge spends in the grinding zone and therefore the reduction rate is a function of the throughput.

Ball Mill - an overview | ScienceDirect Topics

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.
