Conical superfine grinding grading machine

Abstract

The invention provides a conical superfine grinding grading machine which can improve the grinding capacity, the grinding effect and the grinding efficiency, effectively produce a superfine powder product and increase the product yield. A cone is in a conical shape with large top and narrow bottom, a grading shaft penetrates through the bottom end of the cone to be arranged inside the cone, one end of a sleeve is installed onto the grading shaft in the cone through a bearing and held down by a compression nut, the other end of the sleeve is installed on the extending end of the grading shaft through a bearing, two opposite sides of bearings on two ends of the sleeve are respectively provided a washer in a pressing manner, the other side of each bearing is provided with an ejector ring in a pressing manner, a sleeve belt pulley is installed on the extending end of the sleeve in a sleeved manner, a grading belt pulley is arranged on the extending end part of the grading shaft in a sleeved manner, a crushing tray is fixed on the sleeve on the inner lower end of the cone through the cooperation of a bushing and a lower bearing and compressed onto the cone through a bottom gland, the crushing tray and the corresponding cone are respectively provided with grinding rod pins which are distributed in a staggering manner and provided with helical grooves, and a crushing barrel with conical teeth and a crushing ring with conical teeth, which is correspondently installed on the inner wall surface of the cone, are alternately arranged.

Description

technical field [0001] The invention relates to the technical field of pulverizing and classifying machinery for powder materials, in particular to a cone-shaped superfine pulverizing and classifying machine. Background technique [0002] In the processing of non-metallic minerals, polymer materials, industrial raw materials, chemicals, food and feed, etc., due to the different characteristics of some materials, especially some materials with large specific volume, such as white carbon black, AC foaming agent, camphor When ultra-fine pulverization of powder, etc., the pulverization effect of the existing pulverizer is not ideal, the product fineness cannot meet the requirements, and the pulverization efficiency is low, and it is difficult to process materials with various characteristics and shapes. Contents of the invention [0003] Aiming at the problem that existing pulverizers cannot pulverize and process some materials with large specific volume, different charac...
