1. Introduction. Grinding operation is used extensively in the industry of beneficiation, metallurgy, chemical engineering, and electric power. Assisted by the impact and abrasion between media (steel ball, steel rod, gravel, ceramic ball) and ore, the grinding operation reduces the particle size in the mill [[1], [2], [3]].To produce the …
SAG Ball consumption is "average" at 400 g/t while Ball Mill grinding media (3″ balls) usage in 550 g/t. Yet, you add steel and nothing seems to happen, tonnage is not noticeably improved. You need more tonnage and could actually use a larger/coarser transfer size from the SAG to Ball Mill. The ore is "hard" and "bulky".

An instrumented grinding media was designed to mimic the motion state of ordinary grinding balls.. Grinding efficiency index was proposed to evaluate the grinding effect. • Time-domain features were combined with sample entropy in feature extraction.
In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the balls in the mill, the work done by a ball is proportional to its weight. Since the amount of ore crushed varies as …
A ball mill is a tumbling mill that utilizes steel balls as grinding media to grind materials. It can operate either wet or dry, with the capacity to produce products in the order of 100 μm, making it an effective material handling device in grinding applications.
