Vertical centrifugal separation discharge grinding system

Abstract

The invention discloses a vertical centrifugal separation discharge grinding system. The vertical centrifugal separation discharge grinding system comprises a grinding cavity, a grinding rotor, and adischarging and separating rotor mechanism, wherein the grinding rotor is in linkage with a second rotating shaft by adopting a splicing structure, the inner side and the outer side of the grinding cavity are sealed through mechanical seal, a hollow structure is adopted at the front end of the grinding rotor, the second rotating shaft is driven by a second driving mechanism to rotate at a high speed, materials enter the grinding cavity from a feeding port through pumping, under the action of the rotation of the grinding rotor, the materials and a grinding medium are driven to collide with andrub with one another, and the materials flow towards a discharging and separating rotor. The vertical centrifugal separation discharge grinding system is simple in structure and ingenious in design, avertical structure, centrifugal separation, and free-net discharging are adopted, a screen is not additionally arranged, so that the problems that in the prior art, the discharging screen is easy toblock, the flow is small, the cleaning is difficult and the ball leakage are solved.

Description

technical field [0001] The invention relates to a grinding device, in particular to a vertical centrifugal separation discharge grinding system. Background technique [0002] Grinders, also known as bead mills, are mainly used for wet grinding of chemical liquid products. According to their performance, they can be roughly divided into horizontal sand mills, basket sand mills, and vertical sand mills. In the existing vertical grinding and dispersing machine, the liquid-solid separation structure adopts a screen with a thickness of about 0.5 mm. slot. There are 2 to 3 dispersing discs installed on the main shaft inside the barrel—the grinding power source. When the main shaft rotates, the dispersing disc drives the grinding balls and the mixed liquid to make a double-circle motion together. The grinding balls rub against the inner wall of the screen violently. Therefore, the service life of the screen is short, and the screen is an assembly, which is more troublesome and ex...
