Abstract

The invention relates to a coarse powder grader which comprises a cylinder body. The cylinder body comprises an inner cylinder and an outer cylinder. The inner cylinder is fixedly installed in the outer cylinder. The upper end of the outer cylinder is closed and is provided with a feeding hole. A feeding cylinder located in the inner cylinder is fixedly installed at the feeding hole. A material dispersing device located below the discharging end of the feeding cylinder is installed in the cylinder body in a rotating manner. A grading mechanism located between the inner cylinder and the feedingcylinder is further installed in the cylinder body in a rotating manner. A fan for generating airflow moving upwards between the inner cylinder and the feeding cylinder is further arranged in the cylinder body. A fine material passing gap is formed between the upper end of the inner cylinder and the outer cylinder. A ventilating device located below the material dispersing device is arranged between the inner cylinder and the outer cylinder. Coarse powder crashes on the wall of the inner cylinder under the effect of centrifugal force, and slides down to deposit on the lower portion of an inner discharging cylinder. Fine powder rapidly changes the motion direction through a grading mechanism and centrifugal force of the fan to be separated from airflow. The grader has the advantages of small occupied area, little fly dust pollution and large treatment amount.

Description

technical field [0001] The invention relates to a coarse powder classifier. Background technique [0002] In the prior art, linear sieves and disc sieves are mostly used when classifying coarse particles, and linear sieves and disc sieves with different mesh sizes are used to separate coarse and fine materials. low quality defects. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coarse powder classifier with small footprint, low energy consumption, low dust pollution, large processing capacity, energy saving and environmental protection, and convenient particle size adjustment. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a coarse powder classifier, comprising a cylinder, the cylinder includes an inner cylinder and an outer cylinder, the inner cylinder is fixedly installed inside the outer cylinder, the The upper end of the outer cylinder is clos...
