vertical shaft impact crusher

Sand making machines, also known as impact crushers, are mostly used in sand and gravel production lines and stone production lines. The sand making machine can crush soft or medium hard and extremely hard materials, and can also process and shape the materials. Sand making machines have been widely used in cement, various ores, refractory materials, emery, quartz stone, river pebbles, limestone, calcite, glass raw materials, mechanical building stones, bauxite clinker and gold slag. The production efficiency of high-hard, extra-hard and wear-resistant materials such as sintered bauxite is particularly high.

Vertical Shaft Impact Crusher Performance and Features:

1. The sand making machine integrates three crushing modes, and can continuously work for 720 hours.
2. Higher crushing chamber, greater crushing impact.
3. During the parts and material procurement, production and processing, the quality is strictly controlled. Wearing parts is optimally allocated for longer service life.
4. Hydraulic autonomous system: convenient maintenance, high performance, low failure rate.
5. The whole frame adopts elastic reinforcement technology, eliminating the problems like easy fracture of motor frame.

Vertical Shaft Impact Crusher Working Principle

Full center feeding: The material falls into the feeding hopper, enters the high-speed rotating rotor through the central feeding hole, is fully accelerated, and is thrown out through the launch port. First, it collides with a part of the material that falls freely after the rebound, and then hits the surrounding together. The vortex material in the vortex cavity is lined (or on the counterattack block), which is first bounced to the top of the crushing cavity, and then deflected to move downward, and collides with the material emitted from the impeller channel to form a continuous material curtain. The lower discharge port is discharged. The central feeding is accompanied by the annular waterfall feeding: the material falls into the feeding hopper, and then falls through the annular hole, and is divided into two strands by the bulk material tray. One part enters the high-speed rotating impeller through the distributing plate, and the other part falls from the surrounding of the distributing plate and enters the impeller. The material is impacted and broken, and then hits the vortex material lining (or the counterattack block) in the surrounding vortex cavity together, and is first bounced to the top of the crushing cavity, and then deflected to move downward, and the material launched from the impeller channel The impact forms a continuous material curtain, which is finally discharged through the lower discharge port.
