Flexible vertical grinder

Abstract

The invention discloses a flexible vertical grinder. A hammer wheel powder-grinding device and a material sorting balance wheel device are mounted on a star-shaped support of a spindle. The flexible vertical grinder has the technical advantages that different grinding forces are applied by grinding bodies in different layers from top to bottom at a set rotation speed according to different specific surface areas of ground materials, a principle of 'more crushing and less grinding' is met, and the materials in different grades can be ground but are not over ground; a material bed is stable, the phenomenon that 'iron is ground by another iron' is avoided, and abrasion is reduced; the flexible vertical grinder not only can be used for dry grinding, but also can be used for wet grinding, the application range of the multilayer annular grinder is broadened, materials in a barrel are discharged smoothly, and the problem of 'middle distortion' is solved; crushing efficiency is greatly improved, and power consumption of the flexible vertical grinder is greatly reduced as compared with an existing multilayer annular grinder; the flexible vertical grinder is good in integral rigidity, stable in running and low in noise and is free of dust pollution; and the flexible vertical grinder is easy and convenient to maintain.

Description

technical field [0001] The invention relates to a grinding machine. Background technique [0002] The pulverizers reported in existing Chinese patent documents are of a great variety, and the multi-layer combination type of vertical mills has floating mills, stacked planetary vertical mills, pendulum roller mills, and ring mills. [0003] The basic principle is that through the rotation of the central shaft, the rollers on each layer are driven to both revolve and rotate. The rollers rely on inertial centrifugal force to crush the materials falling up and down the ring wall, and the materials falling layer by layer pass through the uniform material of each layer. The disc is thrown towards the wall of the cylinder and falls into the next layer of grinding rings, falling layer by layer. Since the grinding wheels of each layer are driven by the central shaft, they are basically constant at the same rolling pressure to do work on the material, which causes the material with a ...
