Roll Crusher work to pay special attention to the following matters:

1) It is necessary to strengthen the iron ore to work. Non-detritus (first class of solder) fall on the roll of damage breakers, resulting in a parking accident. So breakers should be installed before the iron removal device.

2) viscous materials easily plug broken space, plug failures in dealing with parking should be dealt with, not in a barrel mine in operation.

3) When dealing with the bulk of materials containing more, we should pay attention to lump ores easily broken out space to prevent or wounding or damaged equipment.

4) roll crusher operation after a longer time period, due to the roll surface wear larger size would be too small and products, then we should pay attention to adjusting discharge mouth or on the repair of the equipment.

5) strengthening the inspection of the equipment, lubrication of the equipment on time filling positions, and maintain equipment lubrication good condition.
