Vertical roller mill's history by djsgjg0045


									Vertical Mill (grinding) is increasingly widely used in cement production line. New
 cement production line, coal, raw material grinding mill with vertical accounted for
 than 90%, cement clinker and slag grinding mills are using more and more vertical,
so modern
 cement plant , vertical milling machine has become an important plant process
 which is a series of excellent features that it determined, some are purely mechanical
 technology, the other part is the process of nature.
 The invention is a vertical mill grinding grain by rural stone nianzi inspired. Modern
 vertical milling machine is developed from l906 onwards, it has been constantly
 over the past century has experienced a roller by centrifugal force to pressure to use
 spring pressure, to the present system with a hydraulic pressure pneumatic springs.
 grinding material from the soft to medium hard coal for cement raw materials to
 cement clinker and slag. For the cement industry for the invention of new dry
 rotary kiln production of double and large, make vertical milling machine structure
has been
 continuously improved and large, to meet the requirements of a kiln with grinding.
 CP_ company Peter vertical mill: in the world to use the more than 750 Peter
 there are nearly 500 more than for the grinding of coal, nearly 100 used for grinding
 gypsum. Peter has a durable structure of grinding in the mill site has no bearings or
 lubrication points. This design allows the mill to operate at 700 ? high temperature
 the best of the dry state, and even can be used to calcined gypsum.
 MB vertical roller mill: it has absorbed the advantages of grinding Peter, that is not
 within the roller roller bearings, while the use of three large roller, the compression
 spring will be under pressure ring bearing three principles of layout Static pressure
 people lap roller guide slot grinding mill material. Between the roller guide system
with which to work in the dust flow
 severely worn.
 MPS mill extraordinary company: Germany extraordinary purchased MB patent
roller mill
 with a very short time, then they combine the advantages and Loesche mill grinding
 developed the basic design concept of MPS mill.
 In order to meet the cement grinding process production line of coal, grinding
 raw material, cement clinker and slag grinding requirements, cement machinery
 around the world developed their own brand of vertical milling machine. LM Series
 mill are widely used Liming Heavy Industry in the basis of advanced technology,
 with years of experience in a variety of mill production, design and development of
 grinding equipment. Is a set of crushing, drying, grinding, milling grade transport
 in one ideal. LM Series Vertical mill are widely used in cement, power, metallurgy,
 chemicals, non-metallic mineral industries. Used to block, granular and powder
 ground into powder material required
