Mill cavity. After the shut down to open the milling chamber, with the manual disk found that when the roller does not turn when the roller and the ring there is a collapse block analysis is caused by poor lubrication of roller bearings. Grid according to the technical requirements of processing. After processing each pillar for non-destructive testing. Tire shredder tear out of the finished product less impurities, can be used to add converter steel practice. Recycling the production process of PE, ABS, PPR waste pipe and the nose material has become a wide range of pipe production problems to be solved, and some manufacturers rely on to buy expensive or high power and low efficiency equipment to recover, the cost of investment is too High, and some manufacturers will waste pipe sawn into small pieces and then broken, recycling efficiency is very low. Shuguang Machinery painstaking research and borrow the advanced experience of similar foreign products, through continuous improvement, has successfully developed a large diameter plastic pipe automatic shredding unit, the high degree of automation of the shredding unit, high production efficiency, enabling users to economy Recycling of large diameter plastic waste, pipe and head stock. According to the working conditions of shredders can be pided into dry system, wet system and semi-wet system. Dry system mainly refers to the crushed material must be through the air swing sorting system to separate the metal and non-metallic, while the entire system equipped with dust removal device. Wear-resistant alloy with high hardness alloy welding cutter blade edge, long service life, grinding repair can be repeated use. Effectively reduce labor intensity and improve working environment. Tire shredder is a device used to crush bias and radial tires, the purpose is to crush the tire into about 50 × 50mm plastic block, in order to facilitate the follow-up in the broken process, is the preferred machine for crushing rubber tires. Shredding hollow materials (such as: paint bucket, iron bucket, plastic bucket, cans, etc.) can be equipped with pressing device, the material more easily shredded, to achieve the effect of improving the yield. In addition, you can add rotary screen control the size of the material. Low speed operation, noise and dust can reach higher environmental standards.
