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.
