APPLICATION Toothed Double Roll Crusher is used for Secondary and Tertiary Crushing of soft to medium hard material like lignite, coal, fertilizer, gypsum, chalk, clay, limestone, coke, sinter, etc. OPERATING PRINCIPLE Due to inward opposite rotation of the rolls, the feed material is nipped between the rolls and crushed by piercing and ...
1. The single roll crusher reduces large size particles in the feed to a medium size while producing a considerably lower percentage of fines than other crushers. 2. The single roll design is much more effective in reducing slabby material in comparison to jaw or gyratory crushers. When properly maintained, the "interrupted opening" between ...
Cost. With the design differences also comes cost differences. The Double Roll Crusher is the more cost-effective option of the two. The main differences that make up the majority of the cost differences is the drive configurations. Since the Double Roll Crusher is V-belt driven, lower motor horsepower can be used due to the flywheel design.
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 medium-hard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.

The Roller Screen Crusher includes: dust encapsulation, pre-screen, two crusher drums and after-screen. A pre-crusher might be necessary to put on top of the pre-screen if many lumps are present (e.g. frozen coal). The crusher drums have a releasing mechanism to enable wood pieces, stones and other impurities to be rejected.
