The PF series impact crusher is an industrial crushing machine. It is suitable for a variety of materials with a compressive strength not exceeding 320 MPa (such as limestone, granite, concrete, etc.). It is mainly used in the mining, cement, construction, refractory materials, coal, and glass industries, as well as in metallurgy, chemical, ceramics, highway construction, water conservancy projects, building aggregate, and manufactured sand processing.

The PF impact crusher uses a high-speed rotating rotor and hammers to impact the material, with multiple collisions through the impact liners forming a closed-loop circulation. The discharge particle size and shape can be controlled by adjusting the gap.

Sandreck‘s PF series impact crusher features high crushing efficiency, low power consumption, and uniform product particle size. It reduces the number of crushing stages, simplifies the production process, and is suitable for large- and medium-scale crushing production.

PF Series Impact Crusher Working Principle

The PF impact crusher is a stone crushing machine that uses impact energy to crush materials. During operation, the rotor rotates at high speed, driven by an electric motor. When material enters the hammer impact zone, it is crushed by impact with the hammers on the rotor. It is then thrown onto the impact plate for further crushing. Finally, it bounces back from the impact liner to the hammer impact zone for repeated crushing.

This process is repeated. Material enters the first, second, and third impact chambers from large to small for repeated crushing until it is crushed to the desired particle size and discharged from the outlet.

Adjusting the gap between the impact frame and the rotor can change the discharge particle size and shape of the material.

Features of PF Impact Crusher

1. Large feed opening and high crushing chamber. PF series impact crusher is suitable for crushing materials with high hardness and large block size, producing less stone powder.
2. High crushing ratio, high crushing efficiency, cubic product shape, and selective crushing capability.
3. The gap between the impact plate and the hammer can be easily adjusted, effectively controlling the output particle size and ensuring good particle shape.
4. The hammer, impact plate, and liner are made of new wear-resistant materials, offering impact resistance, wear resistance, and a long service life.
5. Compact structure, high rigidity, and a rotor with a large moment of inertia.
6. Keyless connection, convenient maintenance, economical and reliable.
7. High-chromium hammer, impact-resistant, wear-resistant, and with high impact force.
8. Comprehensive crushing function, high productivity, low wear on machine parts, and high overall efficiency.

PF Series Impact Crusher Applications

In stone processing production lines, the PF impact crusher is typically placed after the jaw crusher for secondary crushing (medium and fine crushing).

PF series impact crushers are widely used in metallurgy, mining, cement, chemical, refractory materials, and ceramics industries, as well as in highway construction, water conservancy projects, building aggregate production, and manufactured sand processing. They also have extensive applications in mining, construction, chemical, power, and metallurgical industries.

PF impact crushers for sale are suitable for small to medium production volumes and environments where hydraulic maintenance is not feasible.
