Hydraulic roller crusher
  • Overview
  • Technical Data
  • Features

Hydraulic roller crusher is used for crushing materials with middle and high hardness, such as metallurgy, building materials, refractory materials and other industrial lines The series hydraulic roller crusher is mainly composed of the parts of roller, the roller support bearings, pressing and adjusting device, and driving device etc..

The adjustment of output size: there is adjusting device of wedge shaped or gasket between the two rollers, it has the adjusting bolt on the top of the wedge shaped device, when the adjusting bolt make the wedge be pulled up, the mobile roller wheel be forced to be away from the fixed wheel by wedge.


The roller crusher has widely application in the industries of mining, building materials, chemical industry, metallurgy, etc. The roller crusher can do secondary and fine crushing of materials with middle hardness or middle minus hardness, such as mineral, rocks, coke, coal, slag, scoria, and fire-proof material, etc.


1. It used for crushing of special solid materials, which can be designed according to the material hardness, namely, testing the pressure resistance as per the materials provided by customers, and then designing roller crusher’s parameters.

2. Mobile Roller, fixed roller and power adopt the hard connection, i.e. coupling device, mobile roller is used the technology of universal joint, which completely avoids the greatest flaw about belt slippage of the outdated type belt (block material).

3. Roller surface is completely adopted cone welding technology of the large hydraulic roller crusher; it can produce more than 80,000 tons after repairing welding once, with the cost about 1000 RMB. The maintenance of whole machine in one year does not exceed 2000 RMB.

4. Feeder adopts the structure of unpowered choosing powder, before the material into the roller crusher, first passing through the device of unpowered choose powder, and less than 3-8 mm of material will be separated and it cannot be into the roller crusher, but the coarse material only be into the vibrating feeder, and evenly and unfolded going into the roller crusher, which can greatly improve the crushing efficiency.

5. Power consumption is one half of hammer crusher

6. When the material is too hard to be crushed, the roller will be back down automatically under the action of the spring, it make the rollers’ gap increase, the hard material or the material cannot be crushed will be fell down, so as to protect the machine from being damaged. Adjust the rollers’ gap can control the output size or granularity and then change the capacity per hour.
