Description

Vertical mill millstone material lifting device

Technical Field

The utility model relates to a cement mill processing field specifically is a device is raised to mill material immediately.

Background

The structural working principle of the grinding disc is as follows: after the material enters the mill, a material layer (commonly called as a material bed) with a certain thickness is formed on the grinding disc, and under the high-speed rotation of the speed reducer, the grinding disc and the grinding roller generate relative motion and extrude the material bed. The material to be ground is extruded by the grinding roller and the grinding disc, is thrown off the disc under the action of centrifugal force and sinks to the position of the nozzle ring, and is blown up and blown away by high-speed air at the position. The metal and heavy ore are settled under the nozzle ring and discharged, the fine powder is carried to the upper part of the vertical mill, the fine powder is separated by a separator, the finished product enters a dust collector along with gas to be collected, the coarse powder is circulated back, coarse particles of the coarse powder are thrown up, the coarse particles lose support along with the reduction of the wind speed, the coarse particles are settled on the disc surface, and the coarse particles enter a press-grinding track by virtue of centrifugal force to perform a new round of circulation.
