The application of vertical roller mills (VRMs) for ore grinding is a part of the strategies against rising energy consumption (Reichert et al., 2015). The VRM technology was introduced in the mid'90s for grinding clinker and slag by LOESCHE (Schaefer, 2001). Fig. 1 illustrates the grinding parts of a Loesche vertical roller mill.

Hammer mill works on the principle of impact between rapidly moving hammers mounted on a motor and the material to be milled. As the hammers revolve at peripheral speeds reaching 10, they direct themselves towards the radial directions and hit the dropping feed breaking its particles into small fragments. Construction of Hammer Mill:

Working The material to be crushed is fed from the hopper into the gap between the two rollers. Due to the rotation of these rollers, the material is crushed. The gap between the rollers can be adjusted to control the degree of size reduction. Uses The roller mill is used for crushing and cracking of seeds before extraction of fixed oil from ...

Principle. The ball mill operates on the principle of impact and attrition. In this, impact occurs between fast moving balls and the powder material while the attrition mode comes in action when the hollow cylinder rotates on its longitudinal axis. All is occurs at low speed and the balls roll over each other. Construction

Rolling is the most important metal forming process. More than 95% of ferrous and nonferrous metals and alloys are processed to their usable shapes by rolling. Usable shapes of rolled metals are plate, sheet, strip, foil, different sections like rail, beam, channel, angle, bar, rod, and seamless pipe, etc., as shown in Fig. and Fig.
