Bevcon toothed double roll crushers are equipped with two identical crushing rolls rotates towards each other. These crushers are ideal at different stages of crushing primarily envisaged to generate very less fines. Hence the crushing ratios are limited to 4 :1.

Since both rolls rotate in same speed, there is no relative motion between roll surfaces. Material entered in crushing chamber is crushed between two crushing rolls. Crushing is accomplished purely by compressive action. In both the rolls one will be stationary and one is self adjustable.

Crusher body is fabricated from steel. Two parallel rotors are fabricated from heavy duty steel plates in hexagonal shape. Crushing ring segments of various types of tooth like trapezoidal, cone shapes are inserted on the rotor. Sometimes a plain rolls are also used for crushing.
