DEVICE FOR GRANULATION OF MATERIALS Russian patent published in 2004 - IPC

FIELD: chemical and other industries. SUBSTANCE: the invention presents a device for granulation of materials and for continuous production of the granulated products in the installations with a fluidized layer. The device is intended for use at the process of granulation of substances extracted from solutions of mineral salts. The device for a granulation of materials includes a chamber for preparation of heat-carrying agent, a body of the chamber for a granulation with a fluidized layer and a gas-distributing lattice, spraying injectors for delivery of the granulated material in the chamber, branch pipes for feeding and removing of the heat-transfer agent, branch pipes for the ready granulate unloading. The spraying injectors are connected with the body of the granulation chamber and by means of the swinging mechanism are made with a capacity to change heights of their location over the gas-distributing chamber. The chamber of granulation is supplied with a sensor located in a zone of the average concentration of the solid phase of the material being granulated in the fluidized layer, that is linked with a swinging mechanism of the spraying injectors. Technical result is prevention of the granulated material drag-out, production of granules of a required homogeneous granulometric composition at simultaneous stabilization of the process. EFFECT: prevention of the granulated material drag-out, production of granules of homogeneous granulometric composition, stabilization of the process. 5 cl, 2 dwg
