Product Description

PF impact crusher is an energy-saving crushing equipment. The processed products are cube-shaped, without tension and cracks, and have good particle shape. It can crush various coarse, medium and fine materials with a feed particle size not exceeding 500mm and a compressive strength not exceeding 350MPa>. For fine materials (granite, limestone, concrete, etc.), the discharge particle size can be adjusted and the crushing specifications are diversified. It is mainly used in metallurgy, chemical industry, hydropower engineering and other industries, especially for the crushing of various ores and rocks, the production of artificial sand and gravel in railways, highways, and construction industries.

Internal structural features

The impact crusher is composed of plate hammer, impact lining plate, spring, frame, rotor and other components. It has good wear resistance and long life of the plate hammer. It can also be equipped with high manganese steel and other wear-resistant alloy steel plates according to the needs of the user. hammer. The special toothed counterattack lining plate can be in the form of zigzag or arc shape. It is made of steel plate and has good wear resistance and long maintenance cycle. The discharge particle size can be adjusted according to actual needs; the rotor is made of integral cast steel. , the structure is strong and durable, the weight of the rotor is large, and it can meet various crushing requirements.

(1) The triple impact plate structure is adopted to increase the number of strikes of the material, reduce hard extrusion, reduce friction, reduce hammer head loss, and extend the service life of wear-resistant parts.

(2) The gap between the impact plate and the hammer head can be easily adjusted by adjusting the bolt, effectively controlling the discharge granularity.

(3) PF1315 type cover opening is equipped with a hydraulic device, making maintenance more convenient.

Product Performance

Working Principle

Impact crusher is a mechanical equipment that uses impact energy to crush materials. When working, the motor drives the rotor to rotate at high speed, and the material enters the blow hammer working area, is crushed by impact with the blow hammer on the rotor, and then is thrown to the impact device for crushing again, and then bounces off the impact lining back to the blow hammer action area. Re-crushing, this process is repeated, and the materials from large to small enter the first, second, and third impact chambers for repeated crushing until the materials are crushed to the required particle size and discharged from the discharge port. Adjusting the gap between the impact frame and the rotor can change the particle size and shape of the material discharged.
