Hammer Crusher Introduction
Hammer crusher is the maximum particle size of 600-1800 direct material crushing to 25 mm or 25 mm below the break with a broken machine. Hammer crusher for cement, chemical, electric power, metallurgy and other industrial sectors crushing medium hard materials such as limestone, slag, coke, coal and other materials in the debris, crushing operations.
Advantages and disadvantages of hammer crusher
Crusher's advantages are: reduction ratio (typically 10-25, the higher 50), high production capacity, product evenly over the phenomenon of small, low energy consumption per unit of product, the structure is simple, light weight, operation and maintenance easy and so on.Crusher's weaknesses are: the hammer and the grate of the screen faster wear, maintenance, and to find a balance for a long time, when crushing hard material materials, wear faster; broken sticky when wet material, easy to plug the grate of the sieve slit, this is easy downtime (the moisture content of materials should not exceed 10%).
Hammer Crusher classification
Hammer crusher is divided into: single-stage hammer crusher, hammer crusher and efficient, playing sand machine, vertical shaft hammer crusher, hammer crusher reversible.
Single-stage hammer crusher (hammer crusher composite)Single-stage hammer crusher hammer crusher is mainly used for crushing limestone, large single-stage hammer can break the 1-meter diameter to 20mm broken limestone directly about a powerful crushing capacity. Single-stage Hammer break in the cement industry has a large number of applications.
Efficient hammer crusher is mainly used for material crushing operation, is an important field of crushing equipment options. To PX efficient Crusher, for example, for the split structure of hammerhead, hammer and hammer handle through the bolt connection. Hammer high wear resistance of the material Cr-Mo alloy, the wear resistance of the hammer is the most durable of the broken hammer. Hammer's split structure, making the hammer replacement is very convenient.
Play sand machine
Play sand machine is the most traditional hammer crusher, hammer wear rod directly connected to the rotor. In order to avoid the breaking hammer, hammer hardness of the material cant be too high.
The biggest advantage is no sieve structure, there is no clogging. But breaking the hammer and hammer vertical shaft liner did not form a large angle between the counter process, so the crushing effect of slightly lower. Hammer for the overall structure, so repair and maintenance is more complicated.
Reversible hammer crusher
Mainly used in soft materials and low-abrasive material crushing operation. Rotor has a positive and negative direction of the ability to operate, can significantly increase the use of hammerhead cycle, reducing the number of replacement hammer.
Hammer crusher main purposes:
Hammer crusher for crushing various mid-hard and abrasive materials weak. The compressive strength of the material does not exceed 100MPa, moisture content of less than 15%. Also used broken fiber structure, strong flexibility and toughness of broken wood, paper or broken asbestos cement waste to recycling asbestos fiber, and so on. In addition, the hammer crusher for crushing not only the production line, sand production line, but also in mineral production line replacement cone crusher. Hammer crusher is the main working parts with a hammer (also known as hammer) of the rotor. Rotor from the spindle, disk, pin and hammer components. The lower part of the rotor, with sieve plate, crushing the grain size smaller than sieve size discharged through the sieve, sieve size larger than the coarse-level resistance to continue to remain in the sieve and grinding by a hammer blow, and finally through the sieve plate from the plane.
Hammer Crusher composition:
Hammer crusher working principle:
Hammer Crusher is a use of impact energy to break the material broken machinery. The machine work, driven by the motor, the rotor high-speed rotation, the material into the zone plate hammer, hammer and hit the rotor on the board broken, and then was thrown back again on the broken device, and from then on the back liner bounced back to hammer the role of district re-broken, this process is repeated, the material descending into one, two, three broken back cavity repeated until the material is broken to the desired size, from the discharge port. Adjust frame and back up the gap between the rotor material change in the shape of particle size and material purposes.
