Abstract

The invention discloses a double-cavity crusher for producing sand. The double-cavity crusher comprises a feeding hole, a first crushing cavity, a second crushing cavity and a third discharging hole, which are communicated in sequence, wherein the first crushing cavity is internally provided with a first crushing rotor; the second crushing cavity is internally provided with a second crushing rotor; an included angle A between an axis lead plane of each of the first crushing rotor and the second crushing rotor, and the horizontal plane is 10 degrees. Each of the first crushing rotor and the second crushing rotor comprises a shaft sleeve, and a first square disc, a second square disc, a third square disc and a fourth square disc which are arranged on the shaft sleeve in parallel in sequence; four dovetail-shaped grooves, which are uniformly distributed, are formed in each of the first square discs, the second square discs, the third square discs and the fourth square discs; and one side wall of each dovetail-shaped groove is a vertical plane and the other side of each dovetail-shaped groove is an inclined plane.

Description

Technical field [0001] The invention relates to a double-cavity crusher for sand making. Background technique [0002] The impact crusher is a crushing machine that uses impact energy to crush materials. The stone material falls directly into the high-speed rotating rotor from the upper part of the machine; the hammer on the high-speed rotating rotor produces high-speed impact on the materials sent into the crushing cavity and is broken, and the crushed materials are thrown into the crushing cavity at high speed along the tangential direction. The counterattack board at the other end is broken again, and then rebounds from the counterattack board to the hammer, repeating the above process. When the materials go back and forth, the materials still collide with each other; because the materials are hit by the blower, the impact of the impact plate and the collision between the materials, the materials continue to produce cracks, loose and crushed. When the particle size of the mat...
