Part of roll crusher work

Roller crusher Instruction In Shibang

To roll crusher is made up crushing roller, spring insurance device, adjusting devices, and transmission device and frame etc. The roll crushers are mainly used for ore dressing, chemical, highway, cement, building materials and other industrial sectors to medium and fine crushing of medium hardness of the ore and rock.

Shanghai Shibang is the China’s largest crusher production base, professional production to roll crusher, jaw crusher, impact crusher and other crusher equipments and grinding mills. We provide the latest crusher prices. This paper briefly introduces each part of roll crusher work characteristics and operation caution to help our customers use the machines better in daily work.

Roll crusher characteristic

Roll crusher install parallelly two opposite direction rollers in opposite direction, they are main working parts of roll crusher. One of the roller is movable, the other is stationary with bearing. Crushing roller is made up axle, roll shaft and wheel hub skin. Each parts of roll crusher play its role, they characteristics are following:

1, Spring Insurance Device:

It is very important parts of roll crusher, the spring tightness degree is related the crusher work normally and overload protection have an important role. The machine work normally, the spring pressure should be able to balance between two rolls produced by the force to keep the row of mouth mine clearance, make the product of granularity. When crusher into the crushing object, the spring should be compressed, forcing mobile crushing roller lateral movement, the discharging increases, ensure that the machines are not damaged.

The Transmission Device:

Motor through the triangle leather belt and a pair of long gears, drive the two broken for the rotary motion at roll. The gear is a kind of tailor-made standard long teeth, when crusher into the broken objects, the distance between the two the roll shaft will change, then long gears still can guarantee the normal mesh. Long teeth gear transmission device is mainly used for low rotation of the double rollers crusher, the roll surface the circumference of the speed is less than 3 m/s. Turn the crusher higher number is used to separate motor drive respectively two rotating rolls, it is the need to install two electric motors, so the price is more expensive.

3, Adjusting Device:

The adjustment device is used to adjust the gap between two crushing roller size that row ore mouth, it is through the increase or decrease two roll bearing the shim between quantity, or use of worm gear and adjusting mechanism to adjust to control the broken the granularity of product.

Roll Crusher Operation Caution

How to crusher equipment, according to normal rules only procedures, to achieve the best effect of production, to roll crusher is not exceptional also, therefore, we summarized the company to roll crusher daily operation caution:

1, strengthen the iron ore clear working. The broken things fall into the roll will damage the crusher of between, as a result causes parking accident. So in the crusher should install before removing iron ore device.

2, viscous material easy jam broken space, in dealing with jam fault, should stop processing, not in the running of tong mine.

Three, to roll crusher operation after a long time, because of the large roll wear, can cause the granularity of product carefully, then should pay attention to adjusting row of equipment or mine mouth overhaul.

4, strengthen the rightness roll crusher parts checks on the lubrication part of the crusher to cheer on time, keep equipment good lubrication state.
