Double tooth roller crusher, belongs to the type of double roller machine, especially suitable for sinter, coal, cement, silicate, glass, ceramics and other industries, mainly used for the crushing of brittle materials below medium hardness, especially in the fine operation of ore. This crusher uses two rollers rotating opposite to each other to control the particle size of the material by adjusting the gap between the rollers, so as to realize the crushing of the material. The roller surface of the double-tooth roller crusher can be coarse or fine teeth.

The working principle of the double-tooth roller crusher is based on the action of rolling force and grinding force. When the material enters the crushing cavity, it is forced between the two rollers by the rodent force of the rotating roller, and the squeezing and grinding of the roller, making the material break. The broken small particles are thrown along the tangent direction of the roller rotation and under the machine through the gap between the two roller axes, forming the finished product.
