Powder Making Equipment Supporting Facilities-Classifier

I. Introduction to the principle
After the material is put into the main machine through the feeding system, it is graded according to the principle that particles of different sizes are subjected to different sizes of centrifugal force in the vortex field. The gas enters into the classifier through the primary air inlet, and the materials to be graded enter into the upper box of the classifier from the inlet, and both of them are dispersed and evened out by the rotating airflow field produced by the high-speed rotating grading wheel, and fall into the area of the deflector disc, and converge with the deflected airflow to get the mixed and uniform gas and material flow.
Mixed gas and material flow along the edge of the grading wheel into the grading wheel, spiral to the centre of the grading wheel movement, fine particles with the inert gas through the gap in the grading wheel into the powder pipeline, the fine powder from the lead cylinder discharged to the cyclone separator, the pulse of the bag collector for collection; relatively coarse particles due to the centrifugal force is greater than that produced by the airflow viscous resistance is thrown out of the grading wheel, by one or two winds The relatively coarse particles are thrown out of the grading wheel due to the centrifugal force is greater than the viscous resistance of the air flow, and then collected by the outlet of the coarse powder after cleaning by the first and second wind.
2、The performance and advantages of the product

1、Precise grading limit and cutting vertex, Newtonian grading efficiency η: 60~95%.
2、Flammable, explosive and oxidising metal powder can be classified by inert gas as medium to achieve closed-circuit classification, inert gas can be recycled, low energy consumption.
3、Horizontal high-speed small diameter grading turbine strictly control large particles.
4、Remove too fine or too coarse particles in the material, effectively solve the phenomenon of entrainment, especially the fine powder extraction is more thorough and stable.
5, the machine can also be used with a variety of crushing equipment (such as: air mill, ball mill, Raymond mill, vibration mill, etc.) combined with a fine powder.
6, the system always maintains stable operation, no need to readjust the operating parameters each time the machine is switched on.
