Double Roll Crusher
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.
Protection of un crushable material is provided to one of the crushing rolls in the form of a retractable roll mounted on heavy duty springs. This retractable roll assembly automatically widens the gap between the rolls during the entry of un crushable material and again come back to the original position.
Operation of Double Roll Crushers is simple. Dual drive arrangements use a separate electric motor and V-belt drive for each roll, resulting in quiet operation and minimal vibration.
