At present, advanced grinding equipment includes vertical roller mill, roller press and high-fineness high-output grinding mill and so on. The advanced grinding technology is a combined grinding system composed of a roller press and a high-fineness high-output grinding mill, which is used for grinding clinker, gypsum and gravel, fly ash and other industrial wastes with grinding fineness of about 400m2/ kg. Use vertical roller mill to grind S95 slag powder with grinding fineness of about 450m2/kg, and then slag powder enters into cement from mill end after being measured. CHAENG Vertical roller mill can only grind block, granular materials whose particle size is greater than 2mm, can not grind small powder materials such as fly ash, and the grinding fineness shouldn’t be more than 550m2/kg, otherwise the vertical roller mill will violently vibrate and damage.However, our vertical mills are still suitable for most environments, ensuring high yield and high quality, production stability and longevity ahead of other vertical mills, very advanced!

(1) superfine grinding mill features: make innovative design on the lining board, partition board, discharging device and grinding media to improve the trajectory of the grinding media. The traditional tube grinding mill only makes radial motion, while the ultrafine grinding mill not only performs radial motion but also axial movement, so as to improve the grinding efficiency. The grinding time of the material is 1.5 times higher than that of the 3.2 * 13m high fine grinding ball mill. During long term continuous grinding operation, the internal temperature rise is small, the grinding material temperature is lower than 95 degrees, non stick to grinding media and lining board, fine powder is not easy to lump.

(2) Ultra-fine powder machine features: use suspension dispersion technology, pre-grading technology, and use air jet air to realize the material suspension dispersion, and strengthen the dispersion of materials. Before the material into the classification area, the pre-grading device will separate part of the coarse material directly to reduce the concentration of selected materials for the clear sorting to provide a good foundation. And then the material into the vortex-type rotor classification zone, get the maximum rating. Cutting small particle size, less than 30μm fine powder, powder efficiency up to 85% or more.
