What's the Difference Between SAG Mill and Ball Mill
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
What Are the Differences between Dry and Wet Type Ball Mill?
The water can wash away the fine particles in time to avoid over-grinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
SAG Mill Process Control
The purpose of a grinding mill is to convert electrical energy into rock breakage. The best use of that asset is to try to maximize the power draw. Try to hold the mill speed high and vary the feed rate to hold the weight (or bearing pressure), but watch out for "cycling" or "surging" that indicates instability in the charge.

Gravity separation by falcon concentrator- an over review
Over the last three decades, in order to reduce environmental issues of processing fine mineral separation methods such as flotation while decreasing capital cost, gravity separation has become significantly important. Falcon concentrators as enhanced gravity separators have been developed for the sharper separation beneficiation of finely ...
Grinding Process
Let us apply these ideas to the derivation of an equation for the rate of grinding in a mill. It follows that if, as appears reasonable, the change of specific surface S cm²/cm³, within a mill depends upon the diameter of the mill, upon the ball diameter and upon the mean diameter of the particle, D, d and b respectively, upon the density of the …
