Abstract

An embodiment of the invention discloses a cyclone grader which mainly comprises a grading cavity in the shape of an inverted cone. A round top plate is arranged at the top of the grading cavity, a fine material outlet is arranged in the middle of the round top plate, an inclined coarse material outlet is arranged at a cone corner of the lower portion of the grading cavity, an air incoming passage is arranged on the grading cavity above the coarse material outlet, and a feeding port is connected on the air incoming passage in an inserted manner. The grading cavity which is in the shape of the inverted cone is adopted, so that a conventional barrel portion is omitted; compared with the fact that air speed of an existing grader is constant, the cyclone grader can effectively utilize the characteristic that air speed gradually decreases in the cyclone grader to realize separation of coarse and fine materials. Fine materials separated by using the cyclone grader are narrow in particle size distribution span and uniform in particle size distribution.

Description

technical field [0001] The invention relates to a classifier, and specifically designs a cyclone classifier, in particular a classifier which can achieve the classification effect by controlling the wind speed entering the ventilation channel. Background technique [0002] The classifier is widely used in a closed-circuit circulation process with a ball mill in a beneficiation plant to divide ore, or in a gravity beneficiation plant to classify ore and fine mud, and to classify ore pulp in a metal beneficiation process, and for ore washing operations. desliming, dehydration and other operations. The machine has the characteristics of simple structure, reliable operation and convenient operation. [0003] The common classifier widely used at present is to separate coarse and fine powder under the action of classifying vortex force after the material is put into the classifier through the feeding mechanism. One of the disadvantages is that the speed of the impeller and the s...
