A Hammer crusher is a kind of equipment that uses a high-speed rotating hammerhead to crush materials in the form of impact. It is generally used for primary crushing. It is used to crush limestone, coal, shale, bricks, gypsum, and other materials in the fields of building materials, chemical industry, electric power, mining, metallurgy, etc. The compressive strength of the materials does not exceed 100MPa.
There are many types of hammer crushers: 1. According to the number of rotors, it is divided into the single rotor and double rotor. 2. According to the rotation direction of the rotor: divided into reversible and irreversible. 3. According to the arrangement of the hammerheads, it is divided into the single-row type and multi-row type.
Its working principle is: the material enters the crusher through the conveyor, and is crushed by the impact of the high-speed rotary hammer. The material obtains kinetic energy from the hammer and rushes to the counterattack plate at high speed to be crushed for a second time. The secondary crushed material and the material rushing to the impact plate are impacted and crushed again. The material with a small particle size is discharged from the grate hole, and the material with large particle size is impacted by the hammer in the crushing chamber, and then crushed again by grinding.
The PC hammer crusher produced by The Nile Machinery has a large crushing ratio, up to 50; high production capacity, low energy consumption per unit product; good output particle size; simple structure, easy operation, and maintenance. The common shortcomings of hammer breaking are: the hammerhead and non-picky eaters wear quickly. When crushing hard materials, the wear is faster, which increases the maintenance and operation industry of the machine; when crushing wet materials, the grate bar screen holes are easy to block. For this reason, it is easy to cause downtime and affect the output, so the water content of the material should not exceed 10%.
The main components of the hammer crusher are the rotor, grate screen, counterattack liner, side liner, etc. Among them, hammerhead and liner are the main wearing parts. Therefore, when purchasing a hammer crusher, the purchase amount of wearing parts can be increased according to the demand.
