(PDF) CMD Consulting uses Rocky DEM power calculations to validate mill
CASE STUDY CMD Consulting uses Rocky DEM power calculations to validate mill designs In a typical mine, the liners and lifters of a comminution mill are expected to last only 6-9 months and can cost upwards of US$500,000 to US$1,000,000 to replace. It is therefore important that the design of these components be carefully …

(PDF) Morrell method for determining comminution circuit specific
A comprehensive energy study was carried out for the Red Chris mill, which processes copper-gold ore at a rate of 30,000 tonnes per day (t/d) and is located in Northern British Columbia.
Is progress in energy-efficient comminution doomed?
Mine-to-mill: The formal idea that optimal fragmentation in blasting can significantly increase the capacity (and therefore energy efficiency) of comminution processes, especially SAG mills, has been around now for 20 years and is still an important option that has not been fully exploited (e.g. Rybinski et al., 2011). 3.
FL launches SAGwise total process control

Selecting Inching Drives for Mill and Kiln Applications
the required mill speed in conjunction with open gear set ratio, and main drive gear reducer ratio where applicable. The normal duty of an incher is intermittent. Therefore lower service factors can be specified since the expected 25 years life of the mill / kiln, the inching system would operate infrequently.

What's the Difference Between Ball Mill, Rod Mill and SAG Mill?
Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption …
