METHOD OF DRYING OF LOOSE MATERIALS Russian patent published in 1994 - IPC

FIELD: drying of loose materials. SUBSTANCE: particles of heated heat carrier are introduced into the material to be dried. Then mixture is separated in electromagnet field and/or by scattering. The heat carrier is further regenerated. The particles of the heat carrier are made of caked aluminum powder or mixture with magnetic conducting material. The particles are balls, cubes, scaly, polyhedron, granules, hollow cylinders, beads and 2-10 mm in sizes. Ferrite powder is used as a magnetic conducting material. Ferrite powder is 10-15 % by mass of aluminum powder. EFFECT: enhanced efficiency. 2 cl
