A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS
As regards "abnormal" rolling conditions which are more or less very "normal" for rolling mills roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll failure have to be discussed and determined (or vice versa) to reduce the risk of repeated roll .

The three roll mill is a dispersing tool. As fine particles tend to agglomerate in traditional agitators, a three roll mill applies tremendous shear force to break apart those agglomerates. With the capability to reduce particles down to 1 micron, the three roll mill is versatile enough for a variety of high shear appliions. FREE Brochure.

Processing of Gun Propellants in Continuous Shear Roll Mills
The processing of gun propellants can be carried out using the continuous shear roll milling process, which consists of two counterrotating and grooved rolls that are run at different speeds and temperatures and that exhibit different surface roughnesses. During the shear roll milling process, the water content of the propellant is decreased upon heat transfer with the rolls .
