The fixed aggregate production line of sand making machine is a classic aggregate processing mode. Due to its flexible configuration, high crushing ratio, high production efficiency, large processing capacity, and the ability to design high-capacity project plans according to customer needs, it is often used for manufacturers with stable processing bases, stone gathering, or relatively stable supply and sales channels.
The working principle of a sand making machine involves the crushing process of materials, including acceleration, impact, friction, and grinding. The following are the detailed steps of the working principle of the sand making machine:
1. Material entry: The material enters the sand making machine from the feeding hopper and is divided into two parts by the distributor.
2. High speed rotating impeller: A portion of the material enters the high-speed rotating impeller and is rapidly accelerated inside the impeller, with acceleration reaching hundreds of times the gravitational acceleration.
3. Material ejection: The accelerated material is ejected from the three evenly distributed channels of the impeller at a speed of 60-70 meters per second.
4. Impact crushing: The ejected material is first crushed by impact with a portion of the material that falls from around the distributor.
5. Material rebound: The materials collide with the material lining inside the vortex support chamber and are bounced back by the material lining.
6. Material impact: diagonally impact the top of the vortex chamber, change its direction of motion, and deflect downwards.
7. Material crushing: The material emitted from the impeller channel forms a continuous material curtain, and the material is subjected to two or more probability impacts, friction, and grinding crushing in the vortex crushing chamber.
8. Material discharge: Crushed materials are discharged from the lower discharge outlet.
9. Circulating screening: Form a closed circuit with the circulating screening system, and generally, the material can be crushed into less than 20 mesh after three cycles.
10. Reduce pollution: During the entire crushing process, materials collide and crush each other without direct contact with metal components. Instead, they collide and rub against the material lining, reducing corner pollution and prolonging mechanical wear time.
11. Self circulation of airflow inside the vortex chamber: The clever self circulation of airflow inside the vortex chamber eliminates dust pollution.
