??? Impact crusher It can be divided into horizontal type (horizontal type) and vertical type
??? (1) Features of horizontal type: ① the opening of the box can be very wide to facilitate maintenance and repair; ② the size of broken garbage can be controlled by adjusting the position of impact plate and fixed block; ③ it is suitable for the treatment of large capacity materials; ④ due to the impact force generated in the vertical direction, the machine is required to be quite solid, but the rotating shaft rotates at high speed and the load acts on the base Therefore, it is necessary to take measures to prevent the vibration; ⑤ the banded garbage may be entangled on the shaft; ⑥ the spark generated by collision may cause the ignition and explosion of inflammable and explosive materials, so it is necessary to take measures to prevent the accident; and (7) it will produce a lot of noise and dust.
(2) vertical features: ① the opening of the box is small; ② the rotary hammer is suitable for fine crushing due to its falling in stages and many crushing times; ③ it is suitable for large capacity processing; ④ the impact load is relatively small and the direction is horizontal, and the base can be small. However, vibration will still occur and vibration prevention measures should be taken;
(3) protection measures: the working environment of impact crusher is very bad, so the material of the machine should be carefully selected. For example: hammer, ring hammer, fixed impact plate and shear plate need to use high manganese cast steel. The hammer pin is made of chromium molybdenum steel and the rotating shaft is made of nickel chromium molybdenum steel. Some are lined with a layer of special wear-resistant steel material on the inner surface of the shell. In addition, it is also necessary to consider the anti cracking of the casing, the protection of the electrical appliances in case of overload and the lifting device during maintenance. During operation, corresponding explosion-proof and fire-proof measures shall be taken. Crusher should be placed in a separate room, good through the television monitoring device to guide the operation.
