coal grinding machine
Process introduction. Vertical coal mill, also known as vertical roller coal mill or vertical coal grinding mill, is a mechanical equipment for crushing and grinding coal into coal power.Mainly used for grinding raw coal, bituminous coal, and other fuels into coal powder, which is supplied to rotary kiln and other kilns in the cement plant and thermal power plant.
Coal
Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity. It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel ...
