With the development and maturity of modern technology, it has a rapid upgrading and renew of coal grinding machine. And the material can achieve a very fine degree with wider application. Meanwhile, with the worsen environment and the increased environmental protection awareness, low carbon life, low carbon economy, low carbon technology and low carbon development is mentioned more and more. Under this circumstance, ball mill with other traditional coal mill with low efficiency, high energy consumption and more dust becomes the huge obstruction of industry while the new type coal mill equipment of power consumption, high efficiency and little pollution has a rapid demand in powder grinding industry.

Liming Heavy Industry focus this trend of environmental protection and energy conservation, following the direction of coal mill industry, using the potential researching and design of creativity, finally designed out a new fine powder making equipment, which is super pressure trapezium coal mill of power conservation, high efficiency and no-pollution. This mill adopts the patents of trapezoidal working surface, flexible connection and roller linkage pressurization, which has the characteristic of high efficiency coal grinding, high output, little dust and accordance with national standard.

It is introduced by Liming experts that super-pressure trapezium coal mill is not only of environmental protection and high efficiency, but also has a good quality of finished product. Compared with Raymond coal mill, this machine is designed into many ladder shapes to decrease the slip velocity of material between trapezium roller and ring, which adds the time for grinding and increase the fineness and quality of finished product for the customers in the world.

So far, super-trapezium coal mill has been widely used in metallurgy, building material, ore mine, express way construction, water conservancy and hydropower, fire-resistant material, steel industry, etc mining product material.
