ABRASIVE MATERIAL GRAIN CLASSIFIER Russian patent published in 2014 - IPC B03B9/00 B03B5/32 

FIELD: process engineering.

SUBSTANCE: invention relates to loose material size, shape and density separation and can be used to classification of abrasive grains in production of abrasive tools. Proposed device consists of the rotor fitted on shaft and engaged with motor shaft via clutch, intake chutes, tray coupled via pipeline with pump. Besides, classifier comprises suspension mixer communicated by pipeline with pump to optimise suspension state prior to feeding to rotor and composed by mixing device, motor and valve. Tray-type intake chutes with baffle plates are arranged one above the other on bed its height being adjusted by pins. Rotor represents a composite surface in the form of flat disc nearby rotational axis and hemisphere with locating conical hole for fitting o the shaft. Rotor shaft runs in rolling bearings inserted via sleeve in bearing barrel secured with cover and motor at said bed mounted with the help of posts on the plate.

EFFECT: higher efficiency of classification to size and shape and process efficiency.
