The strength and fragility of the material introduced

The general performance of the material crushing strength of the degree of difficulty, also known as the fragility of the material. The same crusher crushed under the same

operating conditions of different materials, the production capacity is different, indicating that a variety of materials different friability.

Friability and the material strength, hardness, density, uniformity of the structure, water content, viscosity, cracks, surface condition and the shape factors.

Material strength and hardness are expressed resistance to external force, the strength and hardness of the material is difficult to Grand broken. But the mere hardness of the

material is not necessarily hard to broken, because the material is a block broken split open, so the crusher manufacturer difficulty determining factor is the material strength. The

hardness of the material must be very difficult grinding, crushing process because the grinding process and the different mill grinding process is the body of the material

surface constantly working to generate a large number of fine grinding process, therefore I decided to ease grinding factor is the material hardness.

Uneven nature of the natural material, the same material measured intensity data vary greatly. Therefore, in practical work often measured hardness of the material, the hardness

of the material to some extent reflects the ease of stone screening machine the material, the hardness of the material so that their common friability.

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.
