Rotary disc crusher

Disc crusher is a type of intermediate crusher.

The two disc-shaped disks inside the machine are arranged relative to each other, with one disk rotating in a certain direction while the other disk undergoes eccentric motion, causing the gap around the two disks to intermittently open and close.High energy cone crusher

When assembling, the crushing plate must be firmly attached to the jaw plate, and the two should be leveled between them. Soft metal (such as lead, zinc, etc.) should be used as a gasket between the crushing plate and the jaw plate, and fastened with bolts. When the crusher is working, the crushing plate should not be loose, otherwise it is easy to break or wear the crushing plate, reducing the service life of the crushing plate. So, it is necessary to install the crushing plate properly during assembly to extend the service life of the crushing plate.Rotary disc crusher

The crushed material enters the crushing chamber composed of two disks through the central opening of a disk. When the material is crushed to a sufficient fineness, it is discharged from the gaps around the disks by centrifugal force. The width of the gap can be adjusted. Due to the controlled size of the discharged particles by the gap width, the particle size of the crushed material is relatively uniform. Generally suitable for crushing hard materials. The crusher is composed of a working chamber composed of moving and fixed jaws, which bear enormous crushing force and material friction, and are prone to wear and tear. In order to protect the jaw plate, Huajian Machinery has installed wear-resistant lining plates on the surfaces of the moving and fixed jaws, also known as crushing plates. The surface of the crushing plate is usually made into a tooth shape, and the angle of the tooth peak of the crushing plate is 90 ° to 120 °, which depends on the properties and block size of the crushed material. When crushing large pieces of material, the angle should be larger; When crushing small pieces of material, the angle can be smaller. The size of the tooth pitch depends on the particle size of the product, usually taken as approximately equal to the width of the discharge port, and the ratio of tooth height to tooth pitch can be taken as 1/2 to 1/3. During work, the speed of wear on the upper and lower parts of the crushing plate is different, with the lower part wearing out faster than the upper partJaw crusherWhen working, the crushing plate comes into direct contact with materials and bears enormous crushing force and friction. The service life of the crushing plate is directly related to the work efficiency and production cost of the jaw crusher. Therefore, extending the service life of the crushing plate of the jaw crusher is particularly important. Strengthening the service life of Hubei crushing plates can be considered from aspects such as design, material selection, assembly, and improvement during use.ring hammer crusher
