The counter-impact crushing stone machine (counter-impact crushing machine) is widely used in stone processing in mines. The working principle was that the high-speed rotating rotating roller would drive the hammer and continuously hit the materials falling from the feed port. The materials would be thrown out and hit the counterattack plate, and then bounced back. The materials would also collide with each other until the material's particle size was smaller than the distance between the hammer and the counterattack plate, and then it would be discharged from the discharge port. According to the structure of the chamber, it could be divided into two chambers and three chambers. Those with two counter-attack frames were called two-chamber counter-attacks, and those with one more counter-attack plate (three counter-attack plates) were called three-chamber counter-attacks. The material discharged from the three-chamber counter-attacks was finer and more uniform, suitable for medium and fine crushing operations of various ores. The size of the material was mainly controlled by the speed of the motor and the distance between the plate hammer and the counter-attack plate. The material could be adjusted by adjusting the speed of the motor and the gap between the counter-attack plate and the plate hammer. For example, the gap between the counterattack plate and the plate hammer can be adjusted conveniently by the operation button or the transportation control system through the hydraulic device (note that the distance between the counterattack plate and the plate hammer cannot be less than 15mm). The impact of the plate hammer on the material depends on the kinetic energy of the roller. The adjustment of the speed of the roller can realize the adjustment of the discharge particle size. Although the counterattack breaker performed well in crushing stone in the mine, if it was used to make sand, the sand output would not be higher than 5%, because its cavity was not designed for sand making, and there was no grid at the discharge port, but it could be used for stone shaping.
