Crushing Finer to Reduce Grinding Cost - 911 Metallurgist
For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons per day.
What is the difference between vertical mill and ball mill?
1. The energy consumption rate of the ball mill is relatively low. At present, there is a tendency to be replaced by vertical mills, roller presses, etc., but the ball mill has a "granular shape that is approximately spherical, which is conducive to raw material calcination and cement hydration hardening".

Maximize The Efficiency Of Your Milling Process
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
The Volume Of Cement Industry Consumption Of Grinding Media
Cement mill - Wikipedia. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption is typically half that of a ball mill. However, the narrowness of the particle size distribution of the cement is problematic, and the process has yet to receive wide acceptance.

A feature of ball mills is their high specific energy consumption. A mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, that is, during the grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages: •
