The purpose of this study is to reveal the mechanism of unstable vibration occurring in the grinding operation of roller mills and to show the design guidelines for reducing the vibration. To study the basic cause of the unstable vibration, we first investigated the dynamic characteristics of the mill vibration in its stable state and its unstable state, using a small laboratory roller mill.
Nov 29, 2013 · Electromagnetic melt stirring systems create a rotating magnetic induction field with an induction of B, which induces eddy current j in a direction perpendicular to B, whose velocity is v. Induction B and current j create the electromagnetic force, which works on every unit of volume of steel and bring about a stirring motion in the liquid steel.
