Figure 2: Specific power consumption of ball mill system v/s vertical roller mill system for slag grinding Fundamentally, ball mills use proportionately more energy to produce a finer ground product than do VRMs, and while the energy consumption in a VRM obviously does increase with product fineness, it does so much less rapidly. Indeed,
HLM vertical Mill uses standard modules to design and fabricate pressurization device. With the increase in mill capacity, there is an increase in roller numbers (we can use 2,3 or 4 rollers, 6 rollers maximum) in proper permutation and combination to form the series of equipment of various capacities with minimum standard parts in order to ...

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.
Bowl mill. Similar to the vertical roller mill, it also uses tires to crush coal. There are two types, a deep bowl mill, and a shallow bowl mill. High speed Attrition mill. The attrition mill is a device for mechanically reducing solid particle size by intense agitation of a slurry of .
2. Reducing the power consumption of cement clinker preparation effectively. According to the display of pulverized coal measured data, it can be saving electricity above 30% use of vertical roller mill production per ton cement clinker than traditional tube mill, and .
We have supplied vertical roller mills (VRM) for raw, coal, slag and cement grinding for several decades. The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. It is increasingly used as a solution for efficient grinding.

Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 3042 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 pregrinding to ball mills – is regarded as a breakthrough.
