Description

Technical Field

[0001] This utility model relates to the technical field of gypsum powder coolers, specifically to a gypsum powder rotary cooler. Background Technology

[0002] Gypsum powder is made from raw gypsum through grinding and calcination. During the calcination process, raw gypsum ore loses all adsorbed water and some crystal water, transforming into gypsum. At the same time, the temperature of calcined gypsum reaches about 170℃. Therefore, cooling measures must be taken to allow the gypsum powder to age in the warehouse. The rotary cooler system for building gypsum powder is usually installed behind the aging silo in the powder making workshop to rapidly cool the building gypsum and reduce its temperature.

[0003] Existing rotary gypsum powder coolers employ a hollow structure for their walls, into which cold air is pumped in. The heat from the transported gypsum powder is absorbed through the inner wall, thus cooling the powder. However, this method results in uneven cooling of the gypsum powder located near the inner wall, while the powder further away from the inner wall experiences poor cooling. This uneven cooling negatively impacts the overall cooling effect of the device, leading to lower performance. Utility Model Content
