    Rolling Mills: 6 Different Types of Rolling Mills [Images & PDF]

  • People also askWhat is a roller mill?Roller mill is a type of grinding equipment for crushing materials by pressure between two or more rolling surfaces or between rolling grinding bodies (balls, rollers) and a track (plane, ring, and table).

    Roller Mill

    link.springer/content/pdf/10.1007/978-981-19-0740-…How many types of rolling mills are there?Following are the 6 different types of rolling mills used in many industries: 1. Two High Rolling Mills It contains two heavy rolls fixed one over the other. The rolls are supported in bearing housed in sturdy upright frames (called stands) which are grouted to the rolling mill floor. The vertical gap between the roll is adjustable.

    Drive selection for rolling mills

    Rolling mill DC motors are best at low speed, high torque applications, while AC motors typically need to run above 800rpm to be cost effective. Also the case for higher efficiency of AC motors is many times negated by the wasteful braking methods of some AC drive systems. All this being said, for motors below 200-300kW, or when new …
