Cylindrical Vertical Grading Mill

Abstract

The invention provides a vertical type cylindrical classifying pulverizer. According to the vertical type cylindrical classifying pulverizer, the space distribution of hammer tools can be enlarged, a pulverizing area is formed by a pulverizing cylinder provided with a plurality of hammer tools and a tooth-shaped lining, and spiral teeth of the tooth-shaped lining are provided with grooves, so that the pulverizing efficiency is improved, and particularly tenacious materials and thermosensitive materials can be pulverized efficiently. A partition plate is arranged inside the pulverizing cylinder; backflow holes are formed in the side wall of the pulverizing cylinder; a classifying wheel is suspended above the partition plate of the pulverizing cylinder and used for classifying powder by adjusting the rotation speed of the classifying wheel, and coarse powder circulation is completed through the backflow holes of the pulverizing cylinder. By means of a pulverizing structure composed of the hammer tools on the pulverizing cylinder and the tooth-shaped lining as well as a classifying and circulating structure composed of the classifying wheel and the pulverizing cylinder, the space distribution of the hammer tools is enlarged, and the space range of the pulverizing area is widened; in the pulverizing process, coarse powder and fine powder are pulverized alternately in a groove between every two adjacent spiral teeth, the pulverizing efficiency is improved, blockage of the tooth grooves is eliminated, and the pulverizing effect on the tenacious materials and the thermosensitive materials can be improved substantially.

Description

technical field [0001] The invention belongs to the field of solid pulverizers, in particular to a vertical classifying pulverizer composed of a cylindrical pulverizing rotor equipped with multiple sets of hammer knives, a toothed bush and a classifying wheel. Background technique [0002] The hammer blades of the vertical pulverizers on the market are generally installed on the crushing disc, such as the pulverizers with the application number 201320861999X, the application number 201020160003.9, and the application number 2012103547147.7. Spatial distribution, although some of the patents listed above have improved the pulverization function by improving the structure of the hammer knife, but the pulverization effect is still not good for some tough and heat-sensitive materials. Contents of the invention [0003] The object of the present invention is to provide a cylindrical vertical classifying pulverizer, which can not only efficiently pulverize common materials, but ...
