The roller crusher is suitable for metallurgy, building materials,refractory materials and other industrial sectors broken, higher hardness of the material. The series of roll crusher is mainly composed of the roller, the roller support bearings, compaction and adjusting device and driving unit and other parts. The adjustment of the discharging granularity: with a wedge or gasket between the two roller adjusting device, adjusting bolt, wedge at the top of the device when the adjusting bolt will wedge pulled up, wedge rolling activity to the top from the fixed wheel.
The working principle:
The roll crusher will be broken material feeding the mouth fall between two rollers, extrusion, finished product material nature. When the weather is good or not broken, the roll crusher roller but by hydraulic cylinder or the role of the spring automatic, make the roll gap
increases, sand brick making machine quality or broken down, so as to protect the machine from being damaged. Relative rotation of the two roll gap to a certain extent, change the gap, can maximum discharging granularity control products. Double roll crusher is the use of a pair of opposite rotating round roll, four roll crusher is to use two opposite rotating round roll crushing operations.
Used field
The roll crusher (to roll crusher) applies to the cement, chemical, electric power, mining, metallurgy, building materials, refractory materials, coal and other industries of thick, brittle block material intermediate crushing, it into the grain-size, discharging granularity is adjustable, can fight pressure strength of 160 mpa or less materials
are broken. Especially in the coal industry, the use of native raw coal fragmentation, as long as after iron, removing impurity, without gangue removal, can be directly to broken, broken out of material, granularity and the crushing rate is low, thereby simplifying the coal preparationprocess, reduce the investment and production cost.
Matters you should attention
1) You should enhance the work to iron ore. The broken content (qian primary content) fall into can damage between double roller crusher, as a result causes accident. So in front of the breaker shall be installed in addition to iron plant.
2) Viscous material easy to jam broken space, in the treatment of the jam fault should stop processing, not in the running for tong mine.
3) When dealing with material are too many contain large, attentionshould be paid to large ore is easy to from the crushing space to prevent injury or damage to the equipment.
4) After double roll crusher run a long time, due to the roll surface wear larger, cause fairly granular product, then pay attention to adjusting the row ore mouth or on equipment maintenance.
5) You also need enhance concrete block making machines the inspection of the roll crusher equipment,the lubrication part of the equipment on time to go, keep equipment good lubrication condition.
