LINE FOR COAL ENRICHMENT middlings

摘要

The invention relates to the field of ferrous metallurgy, in particular to equipment for enrichment of intermediate (middlings) and the raw coals can be used in the manufacture of enrichment. The technical problem of creating utility model is to increase the efficiency of the enrichment process middlings coal by reducing the losses of coal concentrate pereobogaschenie crushed middlings sent from the jigs and Heavy-media separator, simplification of the regeneration system magnetite slurry. The line for the enrichment middlings coal contains jigs connected via a mixer with the hydrocyclone and screens, a collection of working suspension connected through a pump to the distributor suspensions and mixer, storage magnetite associated with a collection of a dilute suspension which is connected through a pump to the thickener magnetite and a magnetic separator with collection working suspension. The line is further provided with heavy medium separator diagonal plow, conveying and scraping obesshlamlivayuschim conveyors and the crusher, the jigs and heavy medium separator through a conveying belt connected with diagonal plow, after which successively mounted crusher and scraper obesshlamlivayuschy conveyor, the latter of which, through using a mixer a pump connected to a hydrocyclone, which in turn communicates with the screening units, one of which is intended for cleaning m gnetita, dewatering coal concentrate and transporting it to a product silo, and the second - for transporting and washing the magnetite waste dump. 1 bp f-ly 1 Fig.
