DOUBLE ROLL CRUSHERS

BJD Double Roll Crushers are robust machines that are particularly suited to the reduction of a variety of friable materials of medium hardness such as coal, coke, limestone, clay and medium hard shales. As their name indicates, they crush the material between two rolls. Dependent upon application, the two rolls can be either renewable toothed breaking segments or smooth rolls. A wide range of ...

2.1.5 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]. For rolls that have equal radii and length, tangents drawn at the point of contact of the particle and the two rolls meet to form the nip angle

Roll Crusher - an overview ScienceDirect Topics

Roll Crusher. For a given reduction ratio, single-roll crushers are capable of reducing ROM material to a product with a top size in the range of 200–18 mm in a single pass, depending upon the top size of the feed coal. Double-roll crushers consist of two rolls that rotate in opposite directions. Normally, one roll is fixed while the other ...
