The Difference Between Cast Steel Ball And Forged Steel

4 If using the semi-autogenous mill the large ball with the diameter of 100-150mm can not only reduce the unit consumption but also increase the handling capacity but as a result of the casting process defects the breakage rate of cast ball is much higher than the forged ball.

Estimating Ball Consumption Molycop

Sep 17 2018 For an improved understanding the wear rate constant is directly related to the grinding media consumption rate expressed in grams of steel per kWh drawn by the mill using the simple expression where dr represents the diameter of the new make-up balls periodically charged to the mill.

Factors Influence Ore Grinding Mill Efficiency Jxsc Mining

May 10 2019 2.2 Diameter of steel grinding ball. The grinding efficiency is reflected in the processing capacity of the mill and the fineness of the grinding ore. Large diameter steel ball help reduces grinding time thus improves grinding efficiency in addition putting some small steel ball to control the particle fineness effectively.

How To Reduce The Wear Of Steel Ball In The Ball Mill

Oct 25 2019 The too-small steel ball has a small crushing force on the ore and the grinding efficiency is low. Therefore the reasonable size and ratio of steel ball can not only reduce the consumption of steel ball in the ball mill machine but also effectively improve the grinding efficiency. 5.

Ball Mills An Overview Sciencedirect Topics

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11. The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 2040 water by weight.
