Hammer crusher maintenance and adjustment

Hammer crusher main working parts with a hammer (also known as the hammer) of the rotor. Rotor from the spindle, disk, pin and hammer. Working principle is motor driven rotor

rotating at high speed in the crushing cavity. Material from the upper mouth to feed into the machine, by the high velocity of the hammer blow and grinding. The lower part of

the rotor, with sieve, mesh size is less than crushing the grain discharged through the sieve, sieve size larger than the coarse sieve retention continue to be a hammer blow,

and finally discharged through the sieve machine outside. Only by understanding the hammer Mobile crushing plant works, in order to better safeguard hammer crusher.


One, hammer crusher, such as the coupling of the elastic sleeve damage is found, should be replaced.
Second, the product size can be adjusted by changing the sieve styles or sieve sieve rack mounted on the ends of the tank filler block embedded in order to change the screen of

the gap.
Third, the product adjusting the particle size can be adjusted by rotating the eccentric shaft to the hammer and the gap between the sieve.
Fourth, hammer crusher work, if a sudden strong vibration, should be immediately stopped, identify the cause and eliminate, and then start hammer crusher.
Five, hammer crusher hammer hit some wear and tear on one side, the other side can be reversed using.
VI hammer assembly or replacement, the balance of the rotor must be maintained. Each row of the shaft of the hammer hammer should correspond to the total mass of the hammer axis

equal to the total mass of the hammer, the total deviation must not exceed 1 00g. Quality single hammer little deviation ± 0.5kg.

Hammer crusher is suitable for crushing brittle, medium-hard, surface water does not exceed 2%, not more than 1 50MPa compressive strength of the various materials used in coal,

metallurgy, building materials, chemicals, electricity and other departments breaking or coal crushing plant, coal gangue, limestone, shale, feldspar, gypsum, coke, brick, brown iron

ore, gravel, salt and sulfur, phosphate rock and so on.
