Mill drive power: N = Power consumption = C.G.Di.n = 0.255 x 80 x 3.8 x 16.6 = 1287 kWh (18 ...


Optimization of the make-up ball charge in a grinding mill - Optimization of the make-up ball charge in a grinding mill ...

By optimizing the size of the grinding media, the mill capacity can be increased in many grinding operations. In this specific case, grinding with a −20-mm ball charge required 26% less grinding energy than grinding with a −30-mm ball charge. The energy savings can, in most cases, be converted to an increase in capacity.The combination of a grinding circuit simulator with a model of ball wear in a grinding mill leads to a method to calculate, with a preselected accuracy, the make-up ball charge that optimizes the ...

Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.IntelliSense.io's Grinding Optimization Application directly addresses these challenges: 1. Ball Charge Virtual Sensor: Shows the current ball charge in real-time, alerting operators when new balls need to be added 2. Liner Wear Virtual Sensor: Displays the current state of the mill liner, its wear rate and an Grinding Optimization Application
