In 1980, the first largescale vertical roller mill of the type MPS 3750 C for the grinding of Portland cement and slag cement was commissioned in a German cement plant. The results of permanent operation so far reveal that energy savings are as much as 30 % compared to the ball mill.
One contribution to minimise the increase is to use more efficient comminution equipment. Verticalrollermills (VRM) are an energyefficient alternative to conventional grinding technology. One reason is the dry inbed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here.
High efficiency. Cement vertical mill is a new type of energysaving and consumptionreducing cement equipment. It is the best in production capacity and energy consumption among cement mills. Cement vertical mill has a large singleproduction capacity that can use low voltage and has high grinding efficiency and low energy consumption.

A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Vertical roller mills Roller presses These types of equipment are used for crushing and grinding the raw materials into smaller particles, which are then mixed and heated to form cement clinker.
AGICO VRM Grinding Roller. After decades of continuous improvement and improvement, the vertical roller mill has been widely used in the field of cement raw meal, coal powder, and slag grinding. The grinding roll is a key component in the vertical roller mill, and it is also the most worn in the daily operation of the mill.
Vertical roller mills (VRM) have found applications mostly in cement grinding operations where they were used in raw meal and finish grinding stages and in power plants for coal grinding. The mill combines crushing, grinding, classification and if necessary drying operations in one unit and enables to decrease number of equipment in grinding ...
Vertical roller mill. Vertical roller mill, also called cement vertical mill, it grinds raw materials by the movement between grinding roller, millstone and grinding device.

The pressure drop in raw mill fan is very high. If a vertical roller mill is used for raw grinding in cement industry then a large raw mill fan is installed. Usually cement industries use centrifugal fans to carry out this process. Induced draft fans: Induced draft fans supply the necessary air for the combustion of fuel in the kiln of a cement.
It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are airswept ball mills and vertical roller mills. At present, most cement plants use coal as the main fuel in the clinker production process. The standard coal consumed by the new dry process for producing 1 ton of cement ...
The cement rotary kiln. When operating the vertical roller mill, the operator must control the inlet and outlet air valves to make the air volume of the system in a balanced state, so as not to affect the air pressure at the back end of the rotary kiln. We are AGICO, a professional cement equipment manufacturer and cement plant contractor.
