vertical shaft impact crusher adopts centrifugal principle

Vertical Impact Crusher accelerates the materials to high speed through the high-speed rotating impeller and then throws them out, so that they produce intense impact and friction in the crushing cavity, thus realizing crushing and shaping. Its operation relies on the principle of kinetic energy conversion, so it is a typical high-speed centrifugal impact equipment.

Features of Vertical Impact Crusher:

1. The design of Vertical Impact Crusher pursues the balance between energy consumption and efficiency, with compact structure and high mechanical strength. Compared with traditional crushing equipment, it performs better in both fine crushing and shaping:
2. It has good adaptability to hard rock and strong processing capacity;
3. Can be adjusted through the working parameters to control the discharge particle size and grade;
4. The feeding methods are various, to meet the flexibility of different production lines;
5. The use of impeller structure and anti-friction liner, greatly improving the service life.

Advantages of vertical impact crusher:

1. Compact structure, simple design, high efficiency of kinetic energy transfer, large crushing ratio, reduce the phenomenon of ineffective crushing, superior control of energy consumption.
2. Smooth and reliable operation, low vibration, good noise control, friendly working environment, in line with the current requirements of environmentally friendly production.
3. Strong adaptability to water-containing materials, humidity in 8% or so can still maintain good crushing efficiency, not easy to clogging or bonding problems.
4. The finished particles are three-dimensional prismatic, regular particle size, high packing density, effectively improve the subsequent mixing or paving effect, the finished product has low iron content, suitable for the strict control of impurities in the field.

Working principle of vertical impact crusher:

When the equipment is running, the material enters the machine from the top, and is divided into two typical processes according to the different feeding modes:

1. Center feeding mode: the material falls into the high-speed rotor from the center feeding port, and is accelerated and thrown out from the discharge port at a high speed. High-speed material impact rebound falling free material, followed by multiple collisions with the vortex cavity wall, forming a continuous crushing process, the discharge particles uniform, excellent particle size.
2. The center with the ring waterfall feeding mode: part of the material is guided into the impeller to accelerate, the other part of the natural fall and the formation of high-speed jet collision with the material. The two streams in the air and vortex cavity for many times staggered impact, forming a dynamic collision layer similar to the “material curtain”, greatly improving the crushing efficiency and material shaping effect.

During the whole process, the direct contact between metal parts and materials is very limited, thus reducing wear and prolonging service life.

Typical application areas of vertical impact crusher:

1. Mechanism sand production: especially suitable for granite, basalt, river pebbles and other hard rocks sand making operations;
2. Concrete mixing plant: to provide concrete with well-graded and excellent aggregate;
3. Dry mortar and quartz sand processing: fine process with high requirements on particle form and purity;
4. Construction waste reuse: construction waste can be crushed and processed into usable aggregates, saving resources;
5. Tailings resource processing: for processing iron ore tailings, copper tailings and other slag, to achieve reuse.
