With the rapid development of the economy and the rising of the high productivity and low consumption, a large number of waste metals have been taken place in the society, and the metal mineral is the same resource that can not be found. Under the premise of the sustainable development of the corresponding national call, metal shredder is a kind of resources. The new type of waste steel crushing equipment for energy conservation, environmental protection and waste is a big country of iron and steel consumption, and the mineral resources are scarce. Most of the minerals are imported from abroad, and the cost is high. Under the premise of the state advocating high productivity and low consumption, metal shredder has been the most important link. 5. The operational problems of workers, the cold winter will make people's work power level lower, so we can improve the working environment. 3. The effect in the instrument, the effect of metal shredder parts between the effect of lubricating oil to carry out the operation, and the same temperature is too low may be a certain effect of the lubricating oil, cause the operation of metal shredder is affected, in the winter we have to implement the lubrication of metal shredder important parts. The impact of winter on the machinery industry is common, and we can reduce that part of the impact to low through the correct operation. Metal shredder does not maintain the normal operation and power level of the metal shredder before the operation. At the temperature of 525 C, 70% of the waste plastics can be converted into useful aromatic substances, which can be used as raw materials for chemicals and products and fuel improver for gasoline. Other ingredients can be converted to hydrogen and propane. 4, the preparation of multi-functional resin adhesive. The product has the characteristics of good adhesion, high gloss, strong impact resistance, acid and alkali resistance. The daily output is 1 tons, the cost per ton is 2300 yuan, and the market selling price is 5000 yuan.
