The PF impact crusher is suitable for medium and fine crushing of various soft and medium hard ores, and is mainly composed of a casing, a rotor and a counterattack plate. The rotor has a greater moment of inertia and low energy consumption; the use of high chromium hammers, impact resistance and wear resistance, effectively prolong the service life of wearing parts. Large feed inlet, high crushing cavity, wide range of materials, finished product shape is cubic, no tension cracks, good grain shape, in line with the grade standards of various sand and gravel aggregates.
It is widely used in metallurgy, mining, cement, chemical industry, refractory materials and ceramics and other industrial sectors, as well as highway construction, water conservancy projects, building gravel, machine-made sand processing and other fields. When working, the rotor is driven by the motor to rotate at a high speed, and the material entering from the feed inlet collides with the blower on the rotor, and is broken by the high-speed impact of the blower; the broken material is hit back to the lining board and broken again; Finally, it is discharged from the discharge port. Adjusting the gap between the counterattack frame and the rotor frame can achieve the purpose of changing the size and shape of the material.
1.The machine has a large feed inlet, a high crushing cavity and a wide range of materials. The structure is simple and easy to maintain.
2.The shape of the finished product is cubic, no tension cracks, and good grain shape, which meets the grade standards of various sand and gravel aggregates.
3.The machine structure is simple, mainly composed of a casing, a rotor and a counterattack plate. Through the lifting device, the rear frame can be quickly hit, and the machine parts can be replaced and repaired.
4.The rotor and the main shaft are connected by an expansion sleeve without key, which is convenient for maintenance, economical and reliable.
