After several years of rapid development, the steel industry is also gradually becoming apparent lack of natural resources, tons of production of excessive energy consumption, environmental pollution and other contradictions. Scrap iron and steel industry as "second mining", with energy conservation, reduce pollution, protect the environment, recycling, etc., the impact will grow. In recent years, scrap supply rose year by year, gradually expanding its role in 2009 exceeded fifty million tons, so that the resources have been further recycling.
Because different scrap heap than uneven density, composition vary widely, in turn, affect the development of electric furnace steel. Therefore, the pretreatment of the scrap, steel products can improve the performance and input-output ratio.
There are currently three types of
Metal scrap crusher machine : One package briquetting equipment, mainly used to process sheet, rod and machining process produces chips and other thin materials, convenient transportation and improve the reactor than the density; second, cutting equipment, mainly used to handle large components of heavy scrap and easy into the furnace; Third, broken equipment, not classified to handle low-quality mixed scrap, broken by pure ingredients stability of steel. After the above processing equipment, is nothing but the following purposes: increased density; particle size decreases; slag purification.
Comparing these three types of scrap processing equipment, processing crusher relatively larger and more productive, the most important and most critical is the debris can be removed, if coupled with appropriate separation equipment, the more will mixed steel scrap harmful sub-elected in the nonferrous metals, ferrous metals are very pure quality raw materials. Thus, the scrap broken line is the ideal world of scrap processing equipment.. Coke crusher is a reference to the United States crusher crusher Kong Mubarak designed and developed structural principle of the new products.
Roll mill is small, broken ratio (5-8), low noise, simple structure, the advantages of easy maintenance, high productivity (more than China now 2PGC Roll crusher with high productivity 1-2 times), to be broken Uniform particle size, over crushed low, easy maintenance, overload sensitive, safe and reliable.
Wet
coal crusher crushing a wide range of materials: You can crush coal gangue, shale, slag, cinder, coal, coal, construction waste, garbage and other waste. Wet coal is the biggest benefit crusher crushing humidity of materials is very good, there are wet crushed coal crusher relatively strong adhesive material has a good grinding effect. For coal, electricity, research and other industries and sectors broken dry or containing more than 15% of the points of the coal, ore, rock or other medium hardness materials. Never blocked, the screen is not the end product. Absolute uniformity of the material particle size, all can be controlled in 2MM (mm) below the proportion of 1 mm 70%, the wet coal crusher is crushed brick or other material is absolutely the best choice for high humidity. Another wet coal mill tandem rotor, repeated crushing, grinding and high efficiency so there is no hammer invalid wear phenomenon.
Broken
coke crusher for coal, metallurgy, mining, chemicals, building materials and other industries is more suitable for large-scale coal mines or coal preparation plant (including waste rock) is broken.
Double teeth roll crusher capacity, with the limit between the motor and the reducer from the fluid coupling connection, to prevent power overload, overload sensors, safe and reliable. Roll hydraulic pitch adjustment gear roller bearing lubrication. Optimal Design of gear, pull the broken shear selection, efficient and low consumption, the grain evenly.
