Product details description

The impact crusher is a new type of crushing equipment that has emerged in response to market demand. Unlike the extrusion crushing of EB, the impact crusher is a device that uses impact energy to crush medium hardness brittle materials. PF impact crusher is a new product developed by combining steel machinery with its own advantages and absorbing domestic and foreign technologies. It has the advantages of large crushing ratio, uniform product particle size and less overfilling, low energy consumption, easy equipment manufacturing, convenient maintenance, high yield and energy saving of hard rock crushing, wide range of product particle size adjustment, adjustable discharge particle size, and simplified crushing process. The impact crusher can crush various coarse, medium, and fine materials (granite, limestone, concrete, etc.) with a feed particle size of no more than 500mm and a compressive strength of no more than 250MPa. It is widely used in fields such as highway construction, water conservancy engineering, and power engineering. It has the characteristics of processing finished products into cubes, without tension and cracks, and has a large crushing ratio, high crushing efficiency, and convenient maintenance.

Performance characteristics

1. The impact crusher has a high crushing ratio and good crushing effect. The finished products are mostly cubic, without tension and cracks, and the particle size is controllable.

2. The impact crusher has a large feed diameter, deep crushing chamber, large material throughput, and high output.

3. The design of the impact crusher is reasonable, with a large hammer impact force, high wear resistance, and long service life.

4. The impact crusher has a simple structure, stable operation, easy operation and maintenance, and low operating cost.

Working principle

A counterattack crusher is a crushing machine that uses impact force to crush materials. When the equipment is in operation, the rotor rotates at high speed under the drive of the electric motor. When the material enters the plate hammer action area, it collides with the plate hammer on the rotor and is broken. It is then thrown towards the impact device and broken again. Then, it bounces back from the impact lining plate to the plate hammer action area and re breaks. This process is repeated until the material is broken to the required particle size and discharged from the discharge port, Adjusting the gap between the counterattack frame and the rotor can achieve the goal of changing the material discharge particle size and shape. The material directly falls into the high-speed rotating turntable from the upper part of the machine, and under the action of high-speed centrifugal force, it collides with another part of the flying stones that are distributed around the turntable in an umbrella shape, causing high-speed collisions. After the materials collide with each other, they will form eddy currents between the turntable and the casing, causing multiple blows, friction, and crushing. They are discharged directly from the lower part, forming a closed circuit and multiple cycles until the required particle size is reached.
