Vertical mill construction area is 70% of the tube/ball mill. There is a classifier in vertical roller mill, and it is the hot gas conveying material.

Low noise, about 20 to 25 decibels than ball mill. There is no direct contact between grinding rollers and grinding table, low noise. The noise control meets requirements of Emission Standard of Environmental Noise Control of Industrial Enterprises "(GB12348-2008). It effectively improves the enterprises’ environmental benefits.Low dust concentration meets the National Standard. Vertical mill is sealed and with negative pressure operation, less dust, clean operation environment. The dust emissions data meets requirements of Air Pollution Emission Standards of Cement Industry (GB4915-2004).

As there is no direct contact between metal in the operation, the vertical mill has less metal abrasion, compared with the ball mill, the unit loss is reduced greatly. So in operation process, vertical mill has low depreciation speed, low consumption, and can effectively improve the operation time and stability, and that has greatly reduced production cost.

It is convenient for vertical mill to adjust the rotational speed and roller pressure, wind speed through separator, also it can adjust product fineness easily. The qualified product will be separated in time, what avoids excessive grinding problem of tube mill. The product size is even, high homogenization degree, excellent quality.
