Description
Technical field
The utility model relates to sand Vertical Mill equipment technical fields processed, coarse grained vertical more particularly to automatic screening in grinding
Mill.
Background technique
Currently, the grinding devices such as common cement, slag have ball milling and Vertical Mill, ball milling utilizes abrasive body (such as steel to fall
Ball) percussion and abrasive body by crushing material and mixed, grinding rear portion object with the abrasive action of ball milling inner wall
Material takes grinding machine out of by mill inner ventilation, and other materials go out grinding machine through overground last row.Motor passes through speed reducer band when Vertical Mill works
Movable grinding disc rotation, material fall on mill center from feed opening, under the influence of centrifugal force to the movement of mill edge and by grinding roller
Roll, smashed material is overflowed from mill edge, by the gas upward from nozzle ring (vane) high speed when crossing blocking material ring
Stream carries out first time sorting, and powder is brought by wind to carrying out second of sorting again in the powder concentrator on Vertical Mill top, thick after component selections
Powder returns on mill from the outlet of the powder concentrator coarse powder of lower end, again grinding, forms interior circulation；Fine powder after second of sorting is then
Go out to grind from the air outlet of powder concentrator upper end upwards with air-flow, be collected in the dust arrester installation of system, as product.First
It is not sunk from wind nozzle ring by the coarse granular material that air-flow takes up to coarse fodder storehouse when secondary sorting, by material scraping plate from coarse fodder deslagging
After mouth scrapes Vertical Mill, the bucket elevator through outer circulation feeds the interior grinding again of mill from spout again, forms outer circulation.
Vertical Mill uses bed-grinding principle grinding material, overcomes many defects of ball mill grinding mechanism, has grinding
High-efficient, power consumption is low (than ball mill economize on electricity 20% ~ 30%), and drying capacity is big, allows mill feed material size big, grinding process
Simply, the advantages that occupied area is small, and civil engineering costs is low, low noise, and abrasion is small, and the service life is long, and operation is easy.But it is used at present vertical
Mill there is also certain disadvantage, it is more outstanding the disadvantage is that: at work due to Vertical Mill, all to finished product conveying and inner cyclic process
It is pneumatic conveying, the power consumption for conveying generation is larger, therefore all reduces power using the method for increasing outer circulation amount at present
Consumption.And the material in outer circulation is the material for crossing material entrance coarse fodder storehouse directly after nozzle ring selection by winnowing of blocking material ring,
Fine powder in material and coarse powder due to crossing blocking material ring is mixed in together, and even most of coarse powder is in upper, most of fine powder
Under, along with the upward air-flow of the high speed blown out from nozzle ring cannot be too big, otherwise more coarse powder can be blown into fine powder
Powder concentrator, and further increasing energy consumption, so, it when sorting for the first time is clearly present coarse powder and fine powder cannot be effectively separated
Defect causes part coarse powder to be sent by wind to powder concentrator, and part fine powder enters outer circulation, and sends back to mill center after continued powder
Mill, greatly reduces the mill efficiency of Vertical Mill.
