Embodiment Construction

[0007] The material classification method of the present invention comprises the following steps: 1) the material enters the pulverizer for grinding; 2) the pulverized material is fed into the powder classifier, and the primary air, secondary air and tertiary air are sent into the powder classifier, The rotating air flow is generated, and the materials are sorted in the rotating air flow; 3) The large particle materials after sorting are fed back into the tube mill for grinding; the gas enters the cyclone for re-sorting; the dust is collected by the dust collection point Collection; 4) The gas separated from the cyclone goes through the fan, part of it returns to the powder classifier, and the other part enters the bag dust collector to continue sorting; the finished materials are collected; 5) from the bag dust collector The sorted waste gas is discharged through the fan, and the sorted materials are collected.

[0008] Finally, it is noted that the above embodiments are only...

Abstract

The invention provides a material grading method. The method comprises the following steps that: (1) materials enter a grinding machine for grinding; (2) the ground materials are fed to a powder sorting machine, primary air, secondary air and tertiary air are fed into the powder sorting machine so as to generate rotary airflow, and the materials are subjected to sorting in the rotary airflow; (3) after sorting, large granular materials return to the grinding machine for grinding, gas enters a cyclone for being subjected to sorting again, and dust is collected by a dust collecting point; (4) gas sorted from the cyclone passes through a blower, part of the gas returns to the powder selecting machine, the other part of the gas enters a bag dust collector for continuous sorting, and sorted material products are collected; and (5) waste gas sorted from the bag dust collector is exhausted through a blower, and the sorted material products are collected. The method has the advantages that the grading efficiency is high, the material processing capacity is high, the graded size range of product particles is narrow, the operation is simple, and the particle diameter is convenient to adjust.

Description

technical field [0001] The invention relates to a material classification method, which belongs to the technical field of material separation. Background technique [0002] Material classification is to use the principle of horizontal vortex of air to classify materials. It is suitable for the cement industry to classify powdery materials or other industries to classify equivalent materials. [0003] The existing material grading method has the disadvantages of low grading efficiency, small amount of material to be processed, and complicated operation. Contents of the invention [0004] The purpose of the invention is to overcome the deficiencies of the prior art and provide a material classification method. [0005] The material classification method of the present invention comprises the following steps: 1) the material enters the pulverizer for grinding; 2) the pulverized material is fed into the powder classifier, and the primary air, secondary air and tertiary ai...
