#CMT# #/CMT# The method involve heating powdery products (1) i.e. powder, until a temperature of 700 degree Celsius by the circulation of the products in a current passage tube (5), where the tube is arranged in an inclined manner with respect to a horizontal plane (P) and is in vertical with respect to the plane. The products flow in the tube by gravity. The tube is inclined to an angle of 30 and 90 degrees with respect to the plane. The tube is directly connected and supplied by an electrical supply device (6). The tube is made of non-magnetic metallic material and is constituted by conductress ceramic. #CMT# : #/CMT# An independent claim is also included for a device for thermally treating powdery product. #CMT#USE : #/CMT# Method for thermally treating powdery product i.e. powder, used in a chemical industry or building. #CMT#ADVANTAGE : #/CMT# The method attains very high power treating temperature, thus reducing the treating time. The method treats the products or powders, that are fine, to a temperature to 1600 and 2000 degree Celsius, in a simple and cost effective manner while preventing the regular problems of joining and the skin effect met with the powders of very less grading, and while obtaining high treatment flow and high energetic output. The utilization of the tube heats walls of the tube by the passage of an adapted electric current, thus allowing the temperature obtained on the tube to depend on the quantity of current which traverses the tube and the nuance of the used alloy. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a powdery product heating device.
