China's first production line is broken scrap steel from Guangzhou in 1996 from the United States, for Newell 6000 horsepower crusher. Year, Zhengzhou City grand Machinery Manufacturing Co. keenly aware of new trends in this market, thus seriously research, study advanced concepts scrap steel processing, analysis of the domestic and foreign markets, establish suitable for China's basic models. Zhengzhou City grand Machinery Manufacturing Co., Ltd. with the introduction, digestion and self-innovation, in 2000 successfully developed PSX scrap crushing production line, developed the device to fill the gap, and thus laid the foundation for the development of China's scrap shredder. The device production capacity of 20 to 25 tons per hour psx scrap crusher classification model, its price is high, a full set of equipment for less than 50% of foreign same equipment, so that the scrap crushing production line in our application possible. At this stage, according to the country's resources scattered, thin material and mixing systems haul material inconvenience, stress and other conditions characteristic of electricity in the country or in small-horsepower model distribution is more appropriate. From the available information, the domestic introduction of three high-power crusher, although the yield is high, but it has emerged due to resource problems caused by the phenomenon of underemployment, and the formation of the country on the one hand there are large quantities of scrap materials need to be processed; on the other hand but their faces underemployment situation. So scrap crusher equipment Which is good, small horsepower scrap crushing production line next few years will be the main equipment for processing of scrap crushing. The rotor is the core component of scrap crusher rotor as "disc" structure, by between 13 steel disc and disc rotatably mounted high manganese steel hammer 39 and a number of spacer structure, hammer plate and the inner hole spacers are made of the same shape as the spindle square hole structure, thereby reliably preventing the hammer in the spacer plate and the rotor rotates with wear during operation, the main shaft at both ends by two large roller bearing support to the smaller scrap crushing range machine for bearing with thin lubrication. When the rotor work, hammer circular motion. Disc rotor has the following advantages: 1, scrap processing denser very effective 2, there can not easily break into the host, while the mouth is blocked in the feed ramp, easy removal of 3, 39 hammer scattered work there sequence, the processing scrap very effective 4, the rotor circumferentially uniform gap hammerhead protecting plate is mounted, in order to improve the life of the hammer disc, but also for the flywheel energy storage, to improve the hammer blow scrap tearing ability 5, the amount of disc rotor handle broken hammer steel consumption to a minimum.
