methods of manufacture of building materials. SUBSTANCE: method includes loading of building material from receiving bin through automated gate to scraper feeder ecologically protected from dust wastes, and then material is supplied through vertical pipeline conjugated with inclined pipeline for metal balls to receiving hatch of ball mill. In the course of material grinding, it is dried off, pumped through and its dust free-falling particles, with size not more 0.074 mm, are caught by supplied air flows to side of building material supply and their velocity is accelerated by fan for accelerated mixing with material under grinding. Free-falling and dried out of working zone particles are drawn, separated and directed to cyclone and through automated gates to bin and dust feeder. Air is heated by heater and supplied through pipeline directly to point in front of jet of air flow supplied by fan through pipeline. EFFECT: higher efficiency of preparation of dispersed building materials. 1 dwg |
