Coal grinding equipment of coal mill for lignite
coal mill classification: ball mill, energy saving ball mill, overflow type ball mill, lattice-type ball mill, intermittence ball mill or rod mill, raw materials mill, coal mill.
coal mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics. coal milll can be used for the dry and wet grinding for all kinds of ores.
coal mill changes the intrinsic grinding machine structure. Its body and ground plank are an integral whole. So when fixing, it can be lowered on a plane surface once only. Use double tiered roller axletree with centripetal spherical surface as the support of the host axletree can reduce energy cost by 30%. The intrinsic grille pattern forcing evacuation is instead by over fall pattern controlling one. This can improve the milling of the granule and the quantity dealt with is reduced by 15-20%.
Structure: coal mill is composed by feeding part, discharging part, rotation part and driving part (reducer, small driving gear, electric motor and electric control).
