C. Obry. Karl-Heinrich Zysk. Vertical roller mills are the mills traditionally used for processing granulated blastfurnace slag and for grinding composite cements. From the energy aspect they areThe vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slag and coal slag. It has the benefits of simple structure and low cost of manufacture and use. Vertical roller mills have many different forms, but they work basically the same. All of these forms come with a roller (or the equivalent of rollerVertical roller mill

Roller mills: Precisely reducing particle size with greater efficiency

The roller mill’s ability to reduce materials to a uniform particle size provides more control of product characteristics and minimizes waste, as shown in Figure 1. The mill’s controlled reduction action requires less energy than other grinding methods, improving production effi-ciency and saving energy dollars. Roller mill components andVertical roller mills are adopted in 20 cement plants (44 mills) in Japan. Results Table Energy saving effect of the vertical roller mill Ball mill Specific power Cost estimation About 14million US$ [Newly-built] and about 230 million US$ [retrofitted], including the cost of supplemental facilities [200t-RM/h] [1US$=¥110] Related mattersVertical roller mill for raw Application p rocess materials

Cement grinding Vertical roller mills VS ball mills

For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the of 80mm. The raw materials are mixed in a certain proportion and fed into a vertical roller mill (LOESCHE mill). The vertical roller mill grinds the marital to D 85 of 90µm. The ground product is calcined in a preheater to 850-900℃. After calcination, the materials enter to a rotary kiln and heated to 1450℃ to become clinker.Modeling and simulation of vertical roller mill using population
