Roller crusher

Roller crusher feature:
1.Compact structure, low noise and efficient;
2.Easy to install and only need simple foundation;
3.Can adjust the pressure and size easily.
4.Self protection, the parts can not be damaged when hard materials such as the metals goes into the crushing cavity
Roller crusher structural features:
1.The spacing between rollers can be adjusted to meet the different needs of the desired size.
2.Two rollers’ teeth stagger into each other to achieve the desired crushing. When roller teeth are worn to a certain level, the gap between two rollers can be adjusted to ensure the required size. It’s easy to replace the roller covering.
3.By applying the special structural frame, the bearing support of the movable roller can move on the sliding way horizontally, and connects with the hydraulic cylinder with the accumulator. When the uncrushed foreign materials enter into the machine, they can be discharged by the retreating of the bearing support, so the machine can be protected from damage.
4.The flexible resin screen can prevent the moisture content viscous materials from adhering to the internal cavity.
5.The mud-scraping device can prevent materials from adhering to the roller, so the teeth surface can be more clean and the proper shearing and pressing be maintained.
6.Four main shafts can be lubricated separately or tegether. The bearing support has the grease-discharging hole to discharge the waste grease at any time. It’s easy for maintenance.
Roller crusher working principle:
Through the feed opening, the raw materials fall to between the two rollers, after crushed, the final products drop naturally. When there are unbreakable materials or the material is too hard, the roller will concede automatically under the effects of spring and hydraulic pressure, which will widen the clearance between the rollers and make the hard or unbreakable so as to avoid damaging the machine. The clearance between the two rollers can be adjusted to change the sizes of final products.
Roller crusher application:
The roll crusher is applied in the industry of cement, chemical, electric power, metallurgy, building materials, refractories and other sectors for crushing medium hard materials such as medium and fine crushing of limestone, slag, coke, coal and other materials.It is more superior than ordinary crushers especially in the construction Materials Industry like pisolite and greenbean shake production.
