The lignite mill can grind the lignite into very fine particles to obtain fine lignite. The lignite mill improves the application value of lignite, broadens the application field, and injects new vitality into the development of lignite. The application of lignite can not be separated from the processing of grinding equipment.

In a stoker furnace, the lignite is spread across a grate to form a bed which burns until the lignite is completely burned out. In such a mechanism, the lignite is broken up into approximately 2inch pieces and is fed into the furnace by one of several feed mechanisms: underfeed, overfeed, or spreading.

Lignite is a low rank, brown coal. It is the first product of the coalification process and has a high moisture content and low heating value. Lignite used as a fuel for power generation and as a raw material for producing coke and chemicals. Lignite also used for carbonization. Carbonization the process of heating a material in the absence of ...

Also, the high ash/moisture content of lignite makes its long distance transport very costly and increases overall environmental impacts. Consequently, the use of lignite has been, in the past, limited to power generation at, or close, to the mining site. Another important issue regarding the use of lignite is its environmental impact.

The MPS coal grinding mill with a high drying capacity is very suitable for grinding lignites with feed moistures of as much as 45 per cent. Depending on this high feed moisture, the mill rating is determined by drying whereas for anthracite, hard coal and petcoke the rating of the mill is determined by grinding.

A mill is a machine that is used to break down solid materials into smaller pieces by cutting, grinding, or crushing. The process of milling includes the use of force that acts on a material to tear it apart and reduce its size. Milling improves the performance of ingredients, and the products made from them.
