Technique Of Adding Steel Balls To Ball Mill In Mineral Processing Equipment

- Oct 26, 2017-

The proportion of ball mill steel balls should be determined according to the size of ball mill diameter, ore hardness, ore granularity of the ball mill, hardness of steel ball (mass) and rotational speed of ball mill. When the model of the ball mill is determined, the speed of the ball mill is fixed. The hardness of the ores is measurable. The granularity of the ore in the ball mill is determined by changing the size of the sieve. Usually, the new ball mill has a running-in process, in the running-in process, the steel ball is added for the first time, accounting for the ball mill's maximum ball load of 80%, the proportion of steel balls can be added according to the size of steel ball (Φ120㎜, Φ100㎜, Φ80㎜, Φ60㎜, Φ40㎜). Steel ball added weight, is based on the quality of steel ball, the quality of steel ball, determines the amount of ore ton consumption added. The best use of new wear-resisting steel ball. The best (good) steel ball added is based on the amount of processing per ton of ore (i.e., 0.8 ㎏ per ton of ore added) general steel balls for processing a ton of ore needed (1㎏-1.2㎏). Ball Mill steel ball ratio to be based on the effective length of your mill, whether with roller press, the size of the feed, what kind of liner and structure, the expected sieve fineness and ratio table, how much chromium ball, rotational speed, and so on.
