Toothed Double Roll Crushers - Wear-resistant Steel Rolls, Adjustable Gap, V-belt Or Gearbox Drive, Low Fines, Durable Design

Toothed Double Roll Crushers are used as primary as well as secondary crushing of the friable and brittle materials like Coal, Coke, Sinter (hot and cold), Clay, Earth, Slag, Chalk, Soft Limestone etc. Due to cutting action of the teeth, crushing of material takes place mostly due to shear and not by pressing. Therefore fines generation is bare minimum. Description: Crushing takes place due to two rolls running in to each other and crushing the material caught in the valley of the rolls. One roll is fixed, while other one is adjustable & spring mounted, permising of uncrushable to pass through. Crushing Rolls: Toothed rings are mounted on the heavy fabricated hub and the rings are kept in position by holding bolts. These rings are made of wear-resistant steel, like 1 4% Mn Steel, K.M.D. or any other hardened Steel depending upon the application. Drive through V belts or through Gear Box/Geared Motor. Gap Adjustment: The design of the ECOMAN's Gap-Adjustment system is such, that during running condition gap can be adjusted and also the spring force. There are two spindles located one inside the other in such a way, that inner spindle tightens or lessens the springs, while outer one changes the position of the roll.
