The impeller is driven by the HSPMM to rotate at a high speed in grinding chamber, and then a high turbulence field is formed. Original materials produce strong impact force, self-grinding and shearing effects in the high turbulence motion, and then realizes superfine grinding. In this work, the ITTM driven by an HSPMM is designed andWeb

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.Web
