Coal is very important energy source, and also an important raw material for metallurgy and chemical industry. There are lignite, bituminous coal, anthracite coal and semi-anthracite. When the coal seam is close to the surface, it’s called open pit mine and about 40% of world coal production uses pen pit mining. Seven largest coal reserves countries are the United States, China, Australia, India, Germany, South Africa and Poland.

Coal crusher
Coal crusher is a new professional coal crushing equipment. High efficiency and low consumption are its notable features. Liming Heavy Industry researches and produces the coal crusher that belongs to mill without screen. Wet and dry materials all can be crushed, so there is a very wide range of crushing application, such as coal, gangue, slag and other materials. The product, after being crushed by a coal crusher, has the features of uniform size, perfect shape and gradation. The product size can be controlled within 2mm.

Mobile coal crusher
Large-scale open pit mining uses the new semi-continuous process: single bucket shovel mining - mobile crushing plant - tape transport system. This process along with high adaptability, prominent advantages and 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.

Coal mill
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 the general mills are unable to meet their requirements, 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.).
