6. * 10/18/201514ch42, 14ch24 6 WORKING MECHANISM: Rolls Crushers (High Pressure Grinding Rolls) consists of two parallel rotating rolls turning together (in opposite directions), with feed being directed through the moving gap between them. One roll is fixed, and the other moveable, using hydraulic pressure. As the ore moves through the gap, the For example, a two-roll crusher with 24-inch-long (61 cm) rolls crushing to ¾ inch (2 cm) has a capacity of 75 tons/h (68 metric tons/h), which is approximately 2.5 times the capacity of a single-roll crusher with the same roll width and topsize setting.

Primary coal crusher: Used for larger coal size. The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that isMcLanahan Corporation’s Roll Crusher Troubleshooting Guide can help you solve such situations as the machine fails to start, the electric motor is operating, but the roll(s) not rotating and more. torsion shaft and toggle mechanism should be lubricated by hand every eight hours according to the Lubricant Quantities Chart in theMcLanahan Roll Crushers Support
