cement vertical roller mill for sale

The vertical mill is a kind of mill equipment, widely used in cement chemicals, coal, electricity and other fields. With the advantages of small footprint, low power consumption, small noise, simple process, layout compact, combined with crushing, drying, grinding, classifying as a whole, the vertical roller mill has become the preferred equipment for milling cement raw meal in the modern cement production factories.
The world's first vertical mill was developed by Loesche Company from Germany, who had the mature design already in the year of 1925. At present, the largest vertical mill - LM63．4, has a capacity of 840 TPH, with the millstone diameter of 6.3mm, the power of 5600 KW and is equiped with 4 rollers.

The current abroad manufacturers of vertical mills mainly include Loesehe Company, Fuller Company, UBE Company (LM series of vertical mill), FLS Company (Atox Mill), KHD Company (RM mill) and Pfeiffer Company (MPS series of vertical mill). The domestic manufacturers of vertical mills have a relatively small amount, whose R&D and production are still in the developing level. However, compared with international brands, the domestic brands have some unique characteristics, which are better suited to the domestic market.

The SBM vertical roller mill, capable of grinding and drying materials simultaneously, is our key product: Introduced in 2004, the SBM technology has been continuously improved and optimi-sed to provide superior grinding equipment to our clients. Over 2,00 SBM mills are currently used worldwide in diverse applications, delivering efficient and reliable performance.

In the cement sector, the initial main range of application, namely the processing of coal and raw material, was expanded to include cement grinding. The first SBM vertical roller mill for cement grinding went into operation at Hanover-based Teutonia Zement in 2007, and GEBR. PFEIFFER AG have since established themselves as expert suppliers of cement grinding equipment.

Moreover, SBM mills are also to be found in power plants, an exclusive licence having been granted to Hitachi Babcock, entitling them to manufacture SBM coal mills for coal-fired power stations.

Besides the SBM vertical roller mill, Gebr. SBM AG’s product range encompasses special machines for the classification and drying of mineral bulk materials and for the preparation of lime and gypsum.

In fact, the options have their pros and cons, there is not a perfect solution, the key is when the owners to choose the goal must be clear. Select the program to be considered advanced and mature, but also consider the quality of employees can fit. Such as the one to save tons of cement from the lower operating costs, power consumption, the choice of the final vertical roller mill grinding system is certainly the most advanced. On the current level of technology, consider the grinding station has a running cost advantages and to ensure the quality of cement, endorsed grinding station should be closed-circuit grinding roller press + form grinding process.

verticla roller mill

Vertical roller mill has many different forms, but it works basically the same. All of these forms of machine comes with 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.
Material grinding process: motor through reducer rotating drive disc, the material falls from the mill under the central entrance and exit, under the action of centrifugal force to the disc edge by the roller to move and the crushing, grinding out lap after the material was speed up the flow to and vertical mill with one of the separator, after the meal by the separator back to the mill, the re-grinding; powder while grinding out with air, dust collection equipment in the system to collect down, that is, products . Established through the mill in the pneumatic conveying of materials, a larger air flow rate, which can use waste heat of gas, at the same time dry grinding operations.

Vertical Roller Mill Principle:
Used in cement grinding production grinding parts of its various forms, there is a cylinder, cone type, ball type, etc., and roller surface is also flat, curved, convex round noodles. Applied to the grinding roller to roller grinding along the track bed in close contact with the material strength of a spring pressure, hydraulic, etc..

How Vertical Roller Mill Works:
It has two pairs of grinding rollers, each pair of roller composed of two narrow rollers, mounted on the same axis and can rotate at different speeds. There are two circular disc slot, and roller to the tire shape, work pressure in the tank. Disc roller and the relative sliding velocity between small and roller can swing, even if the roller sleeve and the disc after the liner wear can guarantee a good abrasive, will not affect the grinding effect. Roller symmetrical structure, one side can be upside down after use and wear.
Material grinding process: hydraulic pneumatic roller device through the pressure applied to the material on the crushing of materials, the materials have been moved to crush the edge of disc, from the disc around the nozzle from the exhaust air to improve these materials to Separator.Meal to separate returns after a concentrated mill, fine powder was collected in the precipitator unloading. In the gas flow is small, the meal can not be increased to enhance air flow, they would fall through the nozzle discharged outside the mill, bucket elevator to be transported to the feeder of vertical roller mill, and was re-grinding mill feed people. This cycle features of the way there:
① ring by adjusting the air valve, can change the product fineness can Shide mill bed load material uniformity and stability, improving the grinding efficiency;
② coarse particles in the external circulation, helps reduce Fan power consumption and overall system power
