Double teeth roll crusher suitable for compression strength less than 240Mpa, humidity less than 35% of the hard and soft materials, primary operations in the intermediate and coarse crushing.

The double rollers crusher is widely used for secondary and fine crushing in the industry of mining, building materials, chemical industry, metallurgy and so on. It can crush materials in middle hardness such as rocks, ore, coke, lump coal, slag, mineral slag, cement clinker, fireproof materials, and so on

1. With the advanced hydraulic control system, users can adjust the pressure according to the material hardness, so that can press and pulverize the materials absolutely.
2. With sensor, the roller crushers can load relief when overload, so that to protect the machine.
3. The advanced hard faced technology improves the roller covers' life.
4. Good performance, low cost in operation and easily maintenance.

3.Working Principle

The working principle of double roller crushers is very simple. The whole crushing process, rely on the relative motion of the two jaw plates. One of the jaw plates stay still while the other move against it. And with the movement, the materials between the two plates would be crushed into small elements.

While the plates move against each other, the materials would be crushed and while plates move away from each other, the broken materials which are smaller enough would drop through the discharging opening. And due to the simple structure, double roller crusher is easy to maintain and repair. These features promote its popularity to a great extant.
