Hammer Crusher

Hammer crusher is a kind of efficient crushing equipment, which mainly crushes materials in the form of impact. Hammer crusher plays an important role in the crushing industry with its high efficiency, energy saving and environmental protection. The following is a detailed introduction to hammer crusher:

Hammer crusher is mainly composed of box, rotor, hammer head, impact liner, screen plate and other parts. Several rows of hanging hammer bodies are installed on the main shaft of the crusher. The hammer head is hinged between each row of hanging hammer bodies through a pin shaft. The working surface can be replaced after wear. In order to prevent the axial movement of the hanging hammer body and the hammer, the two ends of the hanging hammer body are fixed with a clamping hammer disc and a locking nut. The two ends of the rotor are supported on rolling bearings, and the main shaft and the motor are directly connected with an elastic coupling. The arc-shaped unloading screen bar is installed under the rotor, and the two ends of the screen bar are installed on the crossbeam, and the arrangement direction is perpendicular to the movement direction of the rotor.

The casing of the hammer crusher consists of the lower body, the rear upper cover, the left wall and the right wall, which are connected as a whole by bolts. The inner wall of the casing is inlaid with a high manganese steel liner, which is convenient for the replacement of the liner after wear. In order to facilitate maintenance, adjustment and replacement of screen bars and hammers, inspection holes are opened on the lower body and both side walls.

The hammer crusher mainly relies on impact energy to complete the material crushing operation. When working, the motor drives the rotor to rotate at high speed, and the material enters the crusher cavity evenly, and is crushed by the impact, shearing and tearing of the high-speed rotating hammer. At the same time, the gravity of the material itself causes it to rush from the high-speed rotating hammer to the baffle and screen bars in the frame. Materials larger than the size of the screen hole are retained on the screen plate and continue to be hit and ground by the hammer until they are crushed to the required discharge particle size and finally discharged from the machine through the screen plate.

There are many types of hammer crushers. According to the number of rotors, they can be divided into single-rotor and double-rotor types; according to the rotation direction of the rotor, they can be divided into irreversible and reversible types; according to the arrangement of the hammers, they can be divided into single-row and multi-row types. In the former, the hammers are installed on the same rotating plane, and in the latter, the hammers are distributed on several rotating planes. In addition, there are single-stage hammer crushers, high-efficiency hammer crushers, sand blasting machines, vertical shaft hammer crushers, reversible hammer crushers, ring hammer crushers, etc.

Hammer crushers are widely used in cement, chemical, electric power, metallurgy and other industrial sectors for medium and fine crushing of medium hardness materials. In addition, it can also be used in crushing production lines, sand making production lines, and to replace cone crushers in mineral processing production lines.

Hammer crushers, with their unique working principle and structural design, show the characteristics of high efficiency, energy saving and environmental protection. It has a large crushing ratio and high production capacity, and can crush materials to the required particle size at one time, reducing energy consumption and production costs. At the same time, the hammer crusher has a simple structure, easy operation and maintenance, low failure rate and long service life. In addition, the equipment has strong adaptability and can be widely used in cement, chemical, electric power and other fields to crush various medium hardness and brittle materials. Most importantly, the hammer crusher adopts a sealed design, which effectively solves the problem of dust pollution and meets the green production requirements of modern industry.
