Using the SMC Test
For tumbling mills the 2 indices relate to "coarse" and "fine" ore properties plus an efficiency factor which represents the influence of a pebble crusher in AG/SAG mill circuits. "Coarse" in this case is defined as spanning the size range from a P80 of 750 microns up to the P80 of the product of the last stage of crushing or HPGR size reduction prior to grinding. "Fine" covers ...

Optimization of mill performance by using
a mill grindout (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining. The complete grindout is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop. The basic principle is to measure the height 'H' from the charge to the shell and the internal mill ...
Mill (grinding)
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (, via a hand crank), working animal (, horse mill), wind or water ().

Crushers are the first stage of ore processing. Depending upon the appliion, power can range from 180 kW (240 HP) to 1200 kW (1600 HP). Rocks as large as 50 cm in diameter are reduced to 15 cm fragments [11, 13] which are then reduced to fine particles in SAG (SemiAutogenous Grinding) or Ball mills.
MILLING CONTROL OPTIMISATION
ore treated was very difficult to mill. In the first two days, the mill experienced numerous power dips (overloads), and on at least seven occasions the feed to the mill had to be completely stopped to grind the mill out. Also, the mill load varied in the range of 125 to 165 tons. These disturbances propagated throughout the milling circuit and ...
