PF Impact Crusher uses impact energy to crush the materials. The rotor rotates at a high speed under the driving force of motor. The materials entering from the inlet impacts the plate hammer on the rotor and would be crushed under the high-speed impact of the plate hammer. The crushed materials would be thrown back to the liner plate for crushing again. Finally, the materials are discharged from the outlet of PF Impact Crusher.

Working Principle

PF Impact Crusher breaks materials with impact force. When working, driven by a motor, the rotor rotates at a high speed. When materials enter the working area of hammer, they are crushed under the high-speed shock. Then broken materials are thrown onto the lining plate for another crushing. Finally, qualified materials are discharged from the opening. Adjusting the gap between the impact rack and rotor rack can change the granularity and shape of finished products.

    Brief History

    In 1942, German Andreson on the base of the structure characteristics and working principle in summary of squirrel cage crusher and hammer crusher, invented and modern crusher structure similar to the AP series impact crusher. This crusher can handle a variety of materials because of its relatively high production efficiency, it isa relatively simple structure, convenient movement and other advantages, so it has been developing rapidly.

    Structure Analysis

    PF Impact Crusher excellent mechanical properties due to its reasonable, optimize the structure, the basic component of crushing cavity: spindle, rotor, hammer, hammer, counterattack plate and frame. The rotor of impact crusher are welded thick steel plate, the expansion sleeve keyless connection on the main shaft, and hammer card is mounted on the rotor, due to wear plate hammer is very powerful in actual use, therefore the plate hammer wedge with the fastening bolt is widely used way of locking plate hammer, replacement of the plate hammer is very convenient.

    Product Application

    PF Impact Crusher main areas of application are metallurgy, mining, cement, chemicals, refractory and ceramics and other industrial sectors, as well as highway construction, water conservancy projects, building rubble, machine-made sand processing and other fields.PF Impact Crusher are mostly used as secondary crusher and it well fits for crushing numerous medium and soft mineral & rock materials.

    Product Advantage

    • Energy efficient wear compression

      Machine crushing ratio, high crushing efficiency, the rotor has a large moment of inertia, low energy consumption; made of high chromium plate hammer, impact resistance, abrasion resistance, effectively extending the service life of wearing parts.

    • Simple structure, easy maintenance

      The machine structure is simple, the main casing, a rotor and a back plate.From the top device can quickly hit the rear frame, the machine replacement parts maintenance operations; expansion sleeve keyless connection between the rotor and the spindle, easy maintenance, economical and reliable.

    • Marker particle size adjustable good grain

      The top of the machine is equipped with a standard discharge port adjusting device can be simple and quick to adjust the back plate and plate hammer clearance control the size of the material; finished cubic shape, no tension cracks, grain shape is good, in line with the various types of sand and gravel aggregate level.

    Operational Principle

    When PF Series Impact Crusher working, the rotor is driven by the motor rotating at high speed from the feed into the mouth of the materials and rotor plate hammer hit by the high-speed impact of the board hammer is broken; crushed material was countered to the liner again broken; Finally, from the discharge port.The gap between the the adjustment impact rack and rotor frame to change the material the particle size and material shape.
