DEVICE FOR CLEANING AND FINE-SORTING GRAIN METALLURGICAL WASTE FINES AND METHOD FOR CLEANING AND FINE-SORTING GRAIN METALLURGICAL WASTE FINES.

摘要

A device for cleaning and fine-sorting grain metallurgical waste fines and the method for cleaning and fine-sorting grain metallurgical waste fines. The material is fed to the device for cleaning of fine metallurgical waste from the feeding tank (1), by means of a feeding mechanism (2) and is transported to initial separator (3), into which air is blown with a fan (4). The most dusty fractions hovering in the initial separator (3) are directed to the collector (6). However, the largest fractions of metallurgical waste fall to the bottom part, and they are removed with a cascade pipeline (7) directed upwards to the cascade separator (8). Lighter fractions accumulated in the cascade separator (8), are directed to the collector (6), and then to the next cascade separator (15), from where lighter and finer fractions of metallurgical waste are directed to expanded cascade separator (16), and the lightest fraction of waste are then directed to the cyclone dust collector (18).
