The FLSmidth Double Roll Crusher DRC withstands the toughest mining conditions while delivering consistent, high-performance crushing thanks to its working principle and several key features. In the DRC the feed material is fed by a continuous feed arrangement into the middle of the machine between both rolls. The rolls are operating with 5 m/s2.1.5 Thickness of the RollFigure 1 is the geometry of a double roll crusher with a spherical particle about to enter the crushing zone of a roll crusher and is about to be nipped [4], [5].

A smooth surfaced roll crusher had a roll diameter of 910 mm. Its suitability to crush an ore at 10.0 t/h was being examined. Preliminary examination showed that the kinetic friction factor was 0.36 when the speed of revolution was 33 rpm. The average diameter of particles fed to the crusher was 200 mm and the S.G. of the ore was 2.8. DOUBLE ROLL CRUSHER WORKING PRINCIPLE. The double roll crusher is an adaptable piece of equipment that uses compression crushing by squeezing the material between two revolving rollers. The flexibility of the machine’s design allows it to process a broad variety of materials, including those that vary in hardness, size, and Double Roll Crusher-MANUFACTURER IN CHINA YOU CAN

Double roll crusher working principle. Roll crushers, or crushing rolls, or double roll crushers, are still used in some mills, although they have been replaced in most installations by cone crushers. They still have a useful application in handling friable, sticky, frozen, and less abrasive feeds, such as limestone, coal, chalk, gypsum/ THE WORKING PRINCIPLE OF JAW CRUSHERS. All jaw crushers feature two jaws: one of which is fixed while the other moves. The working principle of jaw crushers is based on the reciprocating movement of the movable jaw that compresses and crushes the rock or ore between itself and the fixed jaw, as the material enters the zone between the jaws.What Is A Jaw Crusher MEKA

Roll Crushers. Roll Crushers are compression type crushers, and were once widely used in mining. They have, within the last 10 or so years, fallen into dis-favor among mining and processing companies. The probable reason is because the large mines require very large crushed product output with minimal cost, makes the roll crusher uncompetitive.Double-roll crushers are able to crush more finely than single-roll crushers, because they are designed with teeth that mesh together rather than rotating past a smooth plate. They can reduce coal to as little as ¼ inch (0.6 cm) topsize, although they are more commonly operated close to 2 inches (5 cm).Roll Crusher an overview ScienceDirect Topics
