Technical Field
[0001] The utility model relates to the technical field of drying, in particular to a waste heat recovery ultrafine powder drying device. Background Art
[0002] Corundum is a high-temperature refractory material, mainly made of alumina and a small amount of additives through high-temperature sintering. The dried corundum blank needs to be placed in a high-temperature furnace for sintering. The sintering temperature is generally above 1700℃. When grinding ultrafine powder, corundum powder, water and dispersant are mixed into a slurry, and then pumped into a high-speed stirred mill for ultrafine grinding at a certain flow rate. The slurry flows into a circulating slurry barrel, is cooled and then pumped into a high-speed stirred mill for grinding. This process is repeated. When the slurry particle size content reaches a certain value, the hydrocyclone is turned on for classification, and the classified finished products are dried.
