AMIT 135: Lesson 7 Ball Mills & Circuits Mining Mill

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 rest of the media cascades and, in the process, creates particle breakage by attrition.

Autogenous and Semi-Autogenous Mills ScienceDirect

2016-1-1  Pilot plant work by MacPherson and Turner showed that the ball charge should be about 5% of the mill volume. MacPherson and Turner thus recommend 3–8% of the mill volume needs to be steel balls. Reviewing the Australian scene, however, Siddall [1] observed that the ball load can be up to 15% for the grinding of lateritic ores under Australian conditions in a single stage mill.

Steel Balls for Grinding • Sidenor

Steel balls for grinding are produced in a range of 60-100mm diameter. They are used in ore grinding mills, such as SAG (Semi Autogenous Grinding) mills when it is for initial grinding or ball mills for regrinding. The most common applications of these steel balls are in gold, copper, iron, zinc, nickel and silver mining.
