1. Hot rolling and rolling defects: Front and back ... Rolling defects: Mill spring is a defect in which the rolled sheet is thicker than the required thickness because, the rolls get deflected by high rolling forces. Elastic deformation of the mill takes place. If we use stiffer rolls, namely roll material of high stiffness or elastic constant, we could avoid mill spring.

High pressure grinding rolls (HPGR) appliions in the ... · 1.. IntroductionSchönert (1979) has shown that the most energy efficient method of comminuting particles is to compress them between the two plates. Compressing a particle bed between two counter rotating rolls was achieved by the invention of the high pressure grinding rolls (HPGR) (Schönert and Knobloch, 1984).The first commercial appliion of HPGR was in 1985 and its success .

Role of feed moisture in highpressure roll mill ... · In highpressure roll milling, the rate at which dry particles can be fed to the mill is limited by the upward flow of air being evolved as the bed of particles is compressed in the gap. For the experiments that were conducted in this work, we found that the throughput dropped as the gap decreased. Fig. 7 is presented to illustrate the effect of applied load on the throughput to the mill at ...
