Can coal gangue be used to make sand? What sand making machine should be used?
Coal gangue is a solid waste discharged in the process of coal mining and coal washing. It is a kind of black and gray rock with lower carbon content and harder than coal that is associated with coal seam in the process of coal formation.
Coal gangue is not only a great mineral resource. But also a high quality raw material for sand production. Its production performance or particle quality can be comparable to natural sand. So coal gangue is able to do concrete aggregate! Coal gangue is widely used after sand making equipment is used to sand. It can be used in brick making, building aggregate, cinder, brick factory, recycled brick, building materials, road construction and other projects. In the road building, it is used as a paving base material, the effect is very good.
And waste coal waste disposal, occupy a large area of land. The escape or leaching of sulfide from coal gangue will pollute the atmosphere, farmland and water. Rubble hills can also spontaneously ignite and fire, or collapse during the rainy season, silting up rivers and causing disasters.
So using coal gangue to make sand can not only improve the atmospheric environment, but also replace natural sand to relieve the pressure of sand used in the market. After using sand making equipment to make artificial sand, the price can be doubled, the market demand is great, and the profit is broad.
If coal gangue is used as concrete aggregate, which machines are needed to produce it?
Fixed crusher:
1.jaw crusher
Jaw crusher adopts deep cavity crushing, no dead zone, feeding and crushing efficiency is greatly improved, and single energy saving 15%-30%, system energy saving more than double. With advanced technology, long service life, reliable work, easy maintenance and other advantages, it can be used as the first process of crushing coal gangue machine.
2. impact crusher
Impact crusher is often used in sand shaping of the second breaking equipment, the user of the finished product granularity requirements are not high, can only select the "jaw break + impact break" to make coarse sand from coal gangue. For higher requirements on sand quality, it is also necessary to use sand making machine for further fine crushing processing.
3.C series impact sand making machine
C series impact crusher has three functions of crushing, sand making and shaping, which is often used in the final process of sand crushing production line. The finished product mechanism has full sand type, reasonable gradation and stable output.
Mobile crusher:
The mobile station of Maiko Road adopts the integrated operation mode, which can be operated directly to any location of the work site, eliminating the installation of complex site infrastructure and auxiliary facilities of separate components, and reducing the man-hour consumption.
Users can use a variety of configuration forms according to the type of processing raw materials, scale and finished material requirements, with easy installation, strong mobility, efficient material transportation, strong adaptability and other characteristics.
