MIXING DEVICE OF PROCESS LINE FOR MANUFACTURE OF GRANULATED CRYSTALLINE GLASS MATERIALS Russian patent published in 2015 - IPC C03C11/00 

FIELD: construction.

SUBSTANCE: useful model is aimed at expansion of fractional composition of manufactured granules, at manufacture of spherical granules, at complex mechanization of the process line for manufacture of granulated materials on the basis of siliceous rocks (diatomites, gaizes, bergmeals), and also at decrease of prime cost of granulated foam crystalline glass materials. The process line for manufacture of granulated foam crystalline glass materials comprises the mixing device consisting of the manufacture unit for mixing and forming of raw material granules and of the manufacture unit for mixing and foaming of the raw material granules, fractionation and storage of ready products. The mixing device of the process line contains receiving and working bins with batchers, storage devices, a dish-shaped granulating mixer installed on the manufacture unit for mixture and formation of the raw material granules and located downstream the mixing granulator of high-speed type, the drum rotating furnace on the manufacture unit for mixture and foaming of the raw material granules. Besides on the manufacture unit for mixing and foaming of the raw material granules, fractionation and storage of ready products the closed system of process transport and ready product sorting is provisioned which consists of the continuous pneumotransport system which includes pipelines, discharge cyclones and fans. The use of such mixing device on the process line for manufacture the granulated materials has allowed to reduce average bulk density from 210 down to 180 kg/m³. The heat conductivity coefficient has decreased by 15%. The use of complex mechanization has allowed to decrease significantly energy consumption, raw materials costs per 1 m³ of ready products, lower prime cost of ready products.

EFFECT: improvement of equipment performance, decrease of costs of the line service, improvement of environment parameters of manufacture.
