So we have vertical roller mills for grinding of cement raw material, coal and clinker, slag, whatever. in coal grinding, we also have a lot of references in the coal mills for power plants, where we have a licensing agrement with babcock amp wilcox, united states, and i dont know the actual name i think babcock hitachi in germany.
The drive of a vertical roller mill essentially the mill gearbox has to fulfill two tasks the first is to reduce the speed of the electric motor to the selected mill speed and to transmit the torque created by the motor. secondly, the gearbox has to transmit the grinding forces generated by the grinding rollers, from the mill table.
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 energyefficient is the optimum solution when it comes to performing several process steps in one unit.
The vertical roller mill has high energy efficiency and the installation space is smaller compared with tube mills. these days, the vertical roller mills have been widely adopted. astructure 1 the rollers are hydraulically pressed against a disc table and the feed is ground between the rollers and the disc table.
The vertical roller mill is also easy to maintain, any part can be easily repaired and replaced, and the operation is simple. the operation of the grinding mill does not require significant skill it can be mastered after a simple training process.
The vertical roller mill vrm is a kind of large equipment that widely used in cement materials industry. since it always needs to work in the environment of heavy load, high temperature, high pressure and electromagnetic radiation interference, it breaks down easily. if the incipient faults information cant be detected in advance,.
The vrm, depending on the roller size, has a high reduction ratio feed from 80 mm to 140 mm to a product of p80 at 75 m in one pass, the mill is a closed circuit on its own having the comminution and classification of product in a single machine. sulphide coppergold ores are usually sorted by flotation.
There is no doubt that vertical roller mills offer significant advantages over ball mills regarding their energy efficiency. the specific energy consumption of a ball mill is greater than a vertical roller mill vrm that performs the same operations by a factor of between 1.5 and 2, depending on the ball mills degree of optimization.
