Large-scale machinery and equipment is an important link in transportation, scrap crusher transportation mainly includes endless rope transportation and rail transportation. The endless rope transportation works in a continuous situation, but the auxiliary operation of changing the traveling distance of the tramcar must be provided at the terminal of the transportation. The main advantage of rail transportation is that scrap crusher can sufficiently adapt to the change of transportation distance and the bending of roadway, and has a wide range of application. It can be used not only in horizontal roadway, but also in inclined roadway, and the inclination angle is almost unlimited. The disadvantage of rail transport is that transport capacity is closely related to transport distance. When other conditions are the same, the transportation capacity decreases with the increase of transportation distance, and the organization of the work is complex, requiring more auxiliary operations and equipment. The main types of scrap crusher are 600, 800, 1000, 1200, 1400, 1600, 1800 and 2000. The output of scrap crusher is very large, but the speed is not high, usually 900-1000 rpm, so the power does not need to be too large. Type 600 scrap crusher needs 22.5 kilowatt motor. Type 800 scrap crusher usually needs 37 kilowatt motor. Type 2000 scrap crusher needs 110 kilowatt motor. Many people may think that the higher the power is, the higher the output is. In fact, this is a misunderstanding. It is not the bigger the better the power is, the more appropriate it is, the greater the power of the motor may be. It will cause the vibration of the machine.
