Abstract

The invention discloses a roller crusher, which belongs to the technical field of mining machinery. The roller crusher includes sawtoothed rollers whose outer walls are driven to rotate by their mandrels. The rollers are two side by side. Both of the two rollers include a radial fixing part and a radial extension part; the tip of the sawtooth located on the outer wall of the radial extension part is provided with a pressure sensor electrically connected to the controller. The invention can solve the problems of inaccurate particle size control and inconvenient operation of existing roller crushers.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a roller crusher for crushing ore. Background technique [0002] Roller crusher is a kind of equipment for medium or fine crushing of limestone, slag, coke, coal and other materials; there is a roller crusher, including rollers, roller support bearings and roller driving devices, and the rollers are side by side The two rollers are equipped with sawtooth on the outer wall, a wedge-shaped device for adjusting the distance between the two rollers is installed between the two rollers, and the top of the wedge-shaped device is equipped with an adjusting bolt; when working , the material enters the crushing cavity of the machine, and is forced to pass between the two rollers under the action of the nip force when the roller shaft rotates. At the same time, the material is squeezed and sheared by the roller shaft and begins to break. The rotating tangent passes through the ga...
