Abstract

The invention provides a novel micropowder grading equipment. The grading equipment includes: feed inlet, feed pipe, piston rod, parallel excitation table, grading suction cup, solenoid valve, air pump, air pipeline, collection chamber, discharge pipe, recovery chamber, PLC, position sensor. The present invention uses a parallel excitation table with multi-dimensional vibration to vibrate the micropowder raw material to the "excited state", and then uses an intelligent suction system to suck the micropowder to be selected into the collection chamber, which greatly reduces the particle size range of the micropowder. The invention provides a brand-new micropowder grading technology, which solves the problems of low grading efficiency and wide product particle size distribution existing in common methods in the industry, and realizes high-efficiency and fine grading.

Description

technical field [0001] The invention relates to the field of fine powder sorting, in particular to a fine powder classification equipment. Background technique [0002] At present, the demand for all kinds of fine powder materials in food, building materials, chemical industry, metallurgy, refractory and other industries is increasing day by day, and there are many types of equipment for processing fine powder materials, such as ball mill, jet mill, Raymond mill, super Micro pulverizers, roller pulverizers, claw pulverizers and various hammer pulverizers, etc. The particle size distribution of the pulverized micropowder is wide, and the large and small particles stick together to form hard agglomerates, and the shape of the particles is semi-self-determined and amorphous. Due to the different ways of use and purposes, the micropowder still needs further sorting after being crushed. At present, the methods commonly used in the industry, such as gravity sedimentation classifi...
