Double Roll Crusher
Double roll crusher applies to cement, chemical industry, electric industry, metallurgy, construction, refractory material etc. Double roll crusher is usually used in middle and fine crushing stage to crush medium hardness materials including limestone, coke, coal, gravel, gypsum, ores, mine refuse, furnace slag, steel slag etc.
Double Roll Crusher working principle:
Double roll crusher consists of roll wheel, roll bearing, pressing device, adjusting device and driving device etc.
Discharging size adjustment: between two roller equipped with cuneate or gasket adjusting device, top of the wedge device capped with adjustment bolts. When the adjustment bolts pull upward wedge which will bear against the fixed wheel to make it deviate from the movable roller wheel, then the gap between wheels become large, discharging size become bigger, otherwise the opposite, gasket device is through the quantity or thickness to adjust the materials size. When adding gaskets the gap between wheels become large, when reducing gaskets the gap between wheels become small, so the discharging size becomes small. Driving structure is two motors through triangle belt drive to grooved pulley which drag roller rotating according to relative direction. In crushing stage, material is broken by roll wheel; final product is discharged from chassis. For safety, transmission part should be installed safety guard according to actual situation.
Double Roll Crusher Roll design:
Roll shells are available in a variety of alloys for processing the feed material. The roll surface may include various crushing elements, such as intermeshing teeth and smooth faced-all designed to readily grab the feed material and reduce it to desired product size with minimum fines. In addition to the standard roll shells, roll segments can be provided for certain applications.
Double roll crusher to pay attention to the following:
1.Strengthen iron ore’s removing process. Non-broken material fall into the roll will damage crusher, and cause stopping accident. Before crushing, iron ore removing device should be installed.
2.Viscous material will cause jam in the crushing chamber easily. When dealing with jam, operator should stop machine not in the running process.
3.When dealing with large materials, we should note that large ore easily squeezed out from break room prevent injury happened or damage equipment.
4.After long time running of roll crusher, over fine granularity may be happened because of wear and tear of roller surface, then users should pay attention to adjusting discharging area or examining and repairing equipments.
5.Strengthen inspection of Double Roll crusher, fill grease to lubrication part on time, keep equipment in a good lubrication state.
