Our steel industry with continued growth of social economy, embarked on the road of rapid development, from 2004 to 2007, China's crude steel output increase from 270 million tons to 480 million tons, which became the world's steel big country . Faced with these encouraging results, for each member of the steel industry, it is very exciting, but we also see that the steel industry is gradually showing lack of natural resources, tons of production, excessive energy consumption, environmental pollution and other prominent contradictions. To do this, how much money Hangzhou large scrap crusher, iron and steel enterprises in recent years, on the one hand in the "energy saving" make great efforts; on the other hand actively take the road of "recycling economy" development, to expand the use of scrap, particularly is the use of high-quality scrap. From 2004 to 2007, China's scrap supply grew from 54.3 million tons to 68.5 million tons, increased year by year trend, Hangzhou scrap briquetting crusher dealers, natural resources have been further recycling. Means to improve the current internationally recognized quality scrap ─── most realistic is the use of scrap steel scrap crushing production line processing to obtain pure quality scrap. Currently such production lines in the world has more than 700 in operation, but as scrap crushing production line is a kind of large-scale equipment, sophisticated manufacturing technology, high production costs, equipment has been running mainly in Europe and other developed countries, the current China is still the initial stage. Scrap crusher is crushing equipment scrap metal materials in the main equipment, scrap shredder do not say we know that role is to crushing metal materials. But not blindly choose Scrap crusher, scrap shredder, according to need to choose only the most reliable, how do you know what they need to scrap shredder? Zhengzhou grand Machinery Co., Ltd. to do a simple explanation: ① According crushed materials chosen to break scrap metal mainly choose hammer crusher; if requirements common good, such as the broken scrap metal mainly to be cut again Alternatively shredded metal shredder crushing machine, product requirements can be broken very fine particle size be adjusted according to need, the size of the screen aperture determines the size of the material particles. ② Select the specification and the nameplate on the machine to contain a crusher matching motor power kW power according to package. It tends to show that not a fixed number, but there is a certain range. There are two reasons: First, the crushed materials is not the same species, the power required are quite different, for example, under the same working conditions, Hangzhou heavy scrap crusher manufacturers, crushing oil drums and cans power is doubled. Second, when switching to a different mesh, loading the crusher has a great influence. ③ Select crushing finished by conveying means there are three ways according to delivery: belt conveyors, belt conveyors whole package, chain conveyor. Small Scrap crusher by belt conveyor more economic, adapt thin material crushed; they use a medium-sized crusher belt conveyor affordable all-inclusive, drag conveyor high cost and more durable. ④ break dust and noise will inevitably produce selected according to the noise and dust in the crusher broken work, silencer and dust control measures taken in the choice should be to improve the work environment is conducive to the health of the operator. Scrap crusher grand set of equipment includes a main feed conveyor, a feed conveyor, broken feed conveyor, magnetic separation, dust, operation cabinet. Users can choose according to material and production.
