Is the process of coal mining and coal washing discharge of solid waste, is a kind of associated with coal in the process of coal than a low carbon content, coal rock hard dark gray. It includes the waste rock dug in the excavation of the roadway, the waste rock from the roof, the bottom and the lining of the excavation, and the waste rock picked out during the washing process. The main components are Al2O3, SiO2, and also contain a variety of Fe2O3, CaO, MgO, Na2O, K2O, P2O5, SO3 and trace rare elements (gallium, vanadium, titanium, cobalt).

Technological Process

Stage 1: rough
Large coal gangue by bin by vibrating feeder evenly feeding, transportation to jaw crusher for primary crushing, after crushed coal gangue after sieve sieve by belt conveyor to counterattack crusher or cone crusher are finely.
The second stage: breaking up
To counter/cone breaking of coal gangue after finely in the use of circular vibrating screen for screening, the larger of gangue particles return to counter/cone breaking broken again.
PETroleum coke (PETroleum coke) is after distillation according to quality, and the oil separation of crude oil, heavy oil by cracking process, transformed into products, look from the exterior, coke for the irregular shape, size of the black block (or particles), with metallic luster, coke particles with porous structure, the main elements for carbon, occupies 80 WT % (WT is the abbreviation of Weight is the Weight percentage. 5 WT % is equivalent to 50000 parts per million ((PPM is millions.))) above, the rest of hydrogen, oxygen, nitrogen, sulfur and metal elements. Petroleum coke has its unique physical and chemical properties and mechanical properties, is itself a fever of involatile carbon, volatile matter and mineral impurities (sulfur, metal compounds, water, ash, etc.) of these indicators to coke chemical properties.
