grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.
Vertical roller mill has many different forms, but it works basically the same. All of these forms of machine come with a roller (or the equivalent of roller grinding parts), and roller along the track of the disc at the level of circular movement imposed by external grinding roller in the vertical pressure on the disc on the material being the joint action of compression and shear, and to crush.

Alibaba offers 273 vertical roller mill for cement grinding products. About 58% of these are mine mill, 4% are grinding equipment. A wide variety of vertical roller mill for cement grinding options are available to you, such as raymond mill, ball mill.
The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill - built to last, reliable and energy-efficient - is the optimum solution when it comes to performing several process steps in one unit.
Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.
During the past times, ball mill is widely used in cement industry and it has brought much more profits to the cement production businessmen. In the cement industry, the necessity of continuous improvements in the grinding process and the related cost reduction has promoted the diffusion of vertical cement mills .
Summary: The main trends concerning grinding processes in the cement industry are still higher efficiency, reduction of the power consumption and system simplicity. In the case of new orders, vertical mills have increased their share to over 60 % and ball mills have fallen to less than 30 %.

Vertical roller mills are large grinding machines developed, designed and manufactured by Sinoma-tec; Sinoma-tec vertical mills feature a rational and reliable structure as well as an advanced process that combines drying, grinding, separation and conveying, which is suitable for grinding materials of different types and sizes.
Cement Vertical MillCement mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and non-ferrous metals beneficiation, ceramics and other production industries.It makes dry or wet grinding for all kinds of ores and other grind-able materials.
Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pre-grinding to ball mills – is regarded as a breakthrough.
Vertical Roller Mill repair Our long experience with Vertical Roller Mill repairs Excellent references In the 70s, vertical roller mills became increasingly dominant for grinding raw materials main-ly for the cement industry due to their high energy efficiency and excellent drying capacity. For many years Castolin Eutectic
efficient vertical roller mills (VRMs) led to their replacement. Initially, this focused on grinding coal and the cement raw materials, with the adoption of vertical roller mills for cement product grinding – with its finer grinding requirements – com-ing more recently, in the late 1990s. The main reason for
is employed for coal grinding mills and mills in the cement and industrial minerals industry. 2, 3, 4 or even 6 grinding roller con-figurations for a single grinding table can be realised. The first Type LM 26.3 D modular coal grinding mills were devel-oped in 1980 and employed for .
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
