Vertical pulverizer

Abstract

The invention discloses a vertical pulverizer. The vertical pulverizer comprises a rack, a case arranged on the rack, a feeding device arranged on the case, a milling disc device arranged in the case, a drive device arranged on the rack and a movable milling disc water inlet device. The milling disc device comprises a fixed milling disc and a movable milling disc arranged below the fixed milling disc. The feeding device is connected with the fixed milling disc to feed materials into the position between the fixed milling disc and the movable milling disc. The drive device is connected with the movable milling disc and drives the movable milling disc to rotate. A first cooling water circulating structure is arranged in the movable milling disc. The movable milling disc water inlet device is connected with the first cooling water circulating structure to achieve cooling water circulating in the movable milling disc. The vertical pulverizer adopts the above structure, cooling liquid can flow in the movable milling disc by a circle and then flow out, the temperature of the movable milling disc is controlled by adjusting water flow, the temperature of the movable milling disc is controlled to be lower than the material burning temperature, and the problem that the materials are burnt due to milling disc heating is solved.

Description

technical field [0001] The invention relates to the technical field of pulverizers, in particular to vertical pulverizers. Background technique [0002] When the vertical mill is working normally, the motor drives the moving millstone to rotate relative to the fixed millstone through the reducer, and the material falls to the center of the millstone from the inlet through the air lock feeder, and hot air enters the mill from the air inlet at the same time. With the rotation of the grinding disc, the material moves to the edge of the grinding disc under the action of centrifugal force, and is crushed by the grinding knife when passing through the annular groove on the grinding disc. The particles fall directly to the grinding table for re-grinding. When the materials in the air flow pass through the upper separator, under the action of the rotating rotor, the coarse powder falls from the cone bucket to the grinding table for re-grinding. The dust is collected by the dust dev...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to disclose a vertical mill, which solves the problem that the rubber particles are ignited due to excessive temperature during the milling process of the existing vertical mill, which causes the rubber powder to be scorched, and further solves the problem of grinding discs. Fast wear, often need to replace the grinding disc device to make the problem of low work efficiency
