The single most common reason for an increase or drop in the production of fines is the WORK INDEX of the ore. If you remember,
One area of major importance for the identification of impending problems are the feed belts. By visually estimating the PHYSICAL CHARACTERISTICS of the ore it
What I would like to do now is expand upon the grinding theory involved. Bring all of the earlier information together and show you how
As mill operators you don’t have to worry about the mathematics of a Specific Gravity to Density conversion. These specific gravities have all been worked out and
In the method we use to How to Find and Determine Specific Gravity of Rocks (some call it Specific Density because they don’t know better!), we’ll
In the world of mining and milling the “electrical term” LSSM stands for “Low Speed Synchronous Motor” and usually means a mill where the motor rated speed
The Time that the ore spends in the grinding mill is called, RETENTION TIME. This is a very important variable, the longer the retention time,
We will begin with the mill’s bull gear assembly and work towards the motor, The BULL GEAR, sometimes called the RING GEAR is designed to
