Coal is very important energy source, and also an important raw material for metallurgy and stone industry, there are lignite, bituminous coal, anthracite coal, semi-anthracite. When the coal seam close to the surface, it’s called open pit mine and about 40% of world coal production use pen pit mining. Seven largest coal reserves countries are the United States, China, Australia, India, Germany, South Africa and Poland.
Coal crushing & processing
Coal crusher is a new professional coal crushing equipment, efficiency and low consumption are its notable features. Liming Heavy Industry research and production of coal crusher belongs mill without screen, wet and dry materials all can be crushed, thus there is a very wide range crushing area, such as coal, gangue, slag and other materials. Crushed by coal crusher coal product size is uniform, perfect shape, gradation and can be controlled within 2mm (mm).
Large-scale open pit mining using the new semi-continuous process: single bucket shovel mining - mobile crushing plant - tape transport system. This process high adaptability, prominent advantages, advanced, open pit mining technology has become an important technical development direction. Mobile crushing plant includes tire type and crawler type mobile coal crusher, mobile jaw crusher, mobile cone crusher, mobile impact crusher, mobile VSI sand making crusher, mobile vibrating screen plant, etc.
Blast furnace pulverized coal injection system has a very wide range of uses in electric power, iron and steel, metallurgy industry. In the whole system, the preparation of coal is the most important part. Pulverized coal processed form determines the quality of the operational efficiency of the entire system. Because coal requirements, production, general mills unable to meet their requirements. Thus, more and more customers are turning to large-scale mills (vertical coal mill, LUM series superfine vertical roller grinding mill, MTW European trapezium mill, etc).
