Working Principle of the Vertical Composite Crusher

The vertical composite crusher is designed based on the principle of gradually increasing input energy and performing graded crushing of materials.

Working Principle of the Vertical Composite Crusher:

During operation, the rotor fixed to the main shaft rotates at high speed in a specific direction driven by an electric motor. Block-shaped materials are fed into the hopper and fall onto the discharge disc. After being impacted by the high-speed rotating ribs of the discharge disc, the materials are rapidly thrown toward the impact plate under the influence of centrifugal force, resulting in collision.

Under the influence of the inclined surface of the impact plate and gravity, the material is rebounded along the inclined surface into the conical rotor crushing chamber. The material is impacted by the high-speed rotating upper hammerheads, gaining sufficient kinetic energy before being thrown toward the impact plate, repeating the aforementioned crushing process. The material particles collide with each other within the crushing chamber for further crushing and spiral downward in the conical space.

The material enters the cylindrical rotor chamber, where the already crushed particles are further finely crushed, compressed, and ground, repeating the aforementioned crushing process. Through this high-frequency impact, counter-impact, compression, and grinding by the upper, middle, and lower hammers and impact plates, the material is gradually crushed from large to small. Due to the impact of the hammer heads and impact plates on the material within the crushing chamber, as well as the mutual collisions between the material particles, the material fractures along its natural joint planes and bedding planes. When the crushed material is smaller than the discharge gap of the upper rotor, it enters the middle rotor crushing chamber for further fine crushing. The material then enters the lower rotor crushing chamber, where the aforementioned impact, counter-impact, compression, and grinding processes occur again. However, the hammerheads on the lower rotor have a higher circumferential speed than those in the second stage, resulting in greater impact force and smaller gaps, enabling the material to be crushed into smaller particles and ultimately discharged from the machine in the required particle size.
