Calculate Sag Mill Power Draw

Calculating Power Draw when sizing Ball Mills - Grinding .

On the other hand, for SAG mills with grate discharge, the charge level is a bit more variable, so you do sometimes see higher SAG mill power or mill load levels at higher circulating loads. This why the cyclone feed pump or cyclone cluster is often the bottleneck in capacity-constrained ball mill circuits, but mill load or power draw is often the bottleneck in capacity-constrained SAG mill .

Ball Mill Design/Power Calculation

The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power is


power draw of an AG/SAG mill to drop can be gauged by switching the discharge mechanism choice in the model from grate to overflow when predicting the power draw of an AG/SAG mill. smctesting 4

Choosing a SAG Mill to Achieve Design Performance

OPTIMUM GRINDING CONDITIONS FROM PILOT PLANT RESULTS A further explanation is required to explain the importance of designing the SAG mill chamber to draw required power at optimum operating conditions of 75% critical speed and less than 30%

Ball Mill Power Calculations - Mineral Processing Extractive . Aug 23, 2015 . A nice and pretty online Ball Mill Power-draw Calculator was put live by one of the great prophets of grinding.

A Method of C alculating Autogenous/ Semi-Autogenous .

stage ball mills, rod mills or AG/SAG mills when calculating power according to the Bond Third Theory method. Rod mill and AG/SAG mill products are similar and tend to be not as steep as a 0.5 slope when plotted on log-log paper. This is because the particle size distribution (PSD), these mills produce have a coarse fraction but also a fi ne fraction which is not credited for in an 80 per .
