The vertical shaft impact crusher is a highly efficient crushing equipment. With its high efficiency and high-quality crushing effect, it is mainly used to produce high-quality sand and gravel aggregates. It plays an important role in many industries. Its unique crushing principle and structural design ensure the high quality and wide application of the product.

What is the working principle of the vertical shaft impact crusher?

The material falls vertically from the upper part of the machine into the high-speed rotating impeller. Under the action of high-speed centrifugal force, it collides and crushes with another part of the material that is diverted around the impeller in an umbrella-shaped form. After the materials collide with each other, they will form a vortex between the impeller and the casing, and the materials will collide and rub against each other many times and crush them. They will be discharged directly from the bottom, forming a closed-loop multiple circulations, and the screening equipment will control them to achieve the required finished product particle size.

What are the characteristics of the vertical shaft impact crusher?

• High crushing efficiency: It has fine crushing and coarse grinding functions, a strong ability to crush materials, and is less affected by the moisture content of the material. The moisture content of the feed can reach 8%.

• Excellent product particle shape: The needle-like content is extremely low, suitable for aggregate shaping, artificial sand making, and high-grade highway aggregate production, and can be used to produce Class I sand.

• Small footprint: The equipment is highly intensive and saves space.

• Adjustable and controllable stone powder content: Crushing, grading, and dust removal are integrated to ensure product quality.

• Long service life: The life of the rotor and wearing parts is 3-5 times that of the general sand-making machine rotor.

• Needle-like control: The needle-like control is 5%-8% to ensure the good shape of the product.

• Reduced void ratio: The void ratio is reduced by 15-20%, which improves the density of the product.
