SHUMAR 36 x 48 DOUBLE DRUM ROLLS CRUSHER REMOVED. REMOVED. Description. Primary Crusher set up to take a 600mm Feed and rated at 100mm
Abstract. Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute mediumhard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.
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. For a given reduction ratio, singleroll 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. Doubleroll crushers consist of two rolls that rotate in opposite directions.
It can reduce most rocklike materials of 0.5in (13mm) feed size to minus No. 10 (2mm) at a capacity up to 8,000lbs (3,629kg) per hour. Operates at 60Hz. Select preferred voltage of 230V or 460V when ordering. LC14F

As a result, the forces acting in a double roll crusher could be much higher, at least locally, as one would expect for normal single particle comminution. This should be true even if the DRC is, as usual, starvation fed with just about 15 per cent of the crushing gap filled with solids. 3. Crushing and bearing forces.
