Abstract
PURPOSE: To manufacture spherical or square spinel granules by mixing MgO with Al2O3 in a specified ratio and calcining the mixture in the form of a cake contg. water.
CONSTITUTION: Mg(OH)2 or MgO is blended with Al(OH)3 or Al2O3 so that a product is composed of 20W70wt% MgO, 80W30wt% Al2O3 and ≤2wt% other component when they are calcined, and by adding 40W25wt% water to the blend, a cake is prepared. This cake is fed to a rotary kiln and calcined at ≥1,300°C. By regulating the length of the kiln to ≤30m and the peripheral speed to ≤1m∥min, square granules are obtd. By regulating the length to ≥30m and the peripheral speed to ≥3 m∥min, almost spherical granules are obtd.
