Vertical roller mill Introduction. The vertical roller mill which belongs to equipment for fine grinding, fine grinding of hard and medium hard or soft material in the building materials industry, especially used in the cement industry, ceramic industry, power sector, such as cement clinker, limestone, clay, China clay, feldspar, gypsum, barite and coal etc..
One contribution to minimise the increase is to use more efficient comminution equipment. Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here.
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.
Energy saving ball mill for ore and cementome highefficiency roller mills industrial efficiency technology traditionally ball mills are used in cement industry for raw material fuel and as a replacement or in combination with ball mills considerable energy savings.

Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press This and further arguments led to the increased share of VRM for the grinding of finished cement Taking into account that VRM usually have a bigger output than ball mills, it can be declared that the major
In closed circuit grinding, a high efficiency separator (O-Sepa or Sepax, Sepol) is in operation which separates the material that is ground from the mill in to coarse and fine. The fine material is the product while the coarse material is recirculated back in to the mill for further grinding to the required fineness. Vertical roller mills (VRM)
Horizontal roller mills use 65-70% of the energy used in ball mills. Roller press (high-pressure grinding rolls): In this technology materials are crushed between two counter-rotating rollers. These rollers are up to 2 m in diameter and 1.4 m long. Roller presses use 50-65% of the energy used in ball mills.
High-efficiency maximum power for your vertical roller mill Uncomplicated maximum power Our MAAG® MAX Drive system uses two equal drive units for power up to 15,000 kW, while also giving you the potential to keep up your production by running only one of the drives as you service the other drive or the second half of the rollers.
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.

Raymond Roller Mills: More than 2,000 roller mills have been supplied since the first mills were designed in the late 1800's. These early machines were the forerunner of the heavy-duty, rugged ring-roll mill manufactured today. The roller mill provides the needed flexibility to economically and efficiently process a wide variety of materials.
With the introduction of the high compression machines such as High Pressure Grinding Rolls (HPGR), Vertical Roller Mills (VRM) and Horomills, efficiency of the grinding circuits was improved in terms of energy and downstream effects. Among these devices, vertical roller mills have an important position in cement and mining industry.
