SA spinel brick for high temperature zone and cooling zone of rotary kiln

——Cooperation with Yunnan Mengzi mining and Metallurgy Co., Ltd

Yunnan Mengzi mining and smelting Co., Ltd., a private mining and smelting enterprise integrating mineral resources exploration, mining and smelting, has won the title of national excellent private science and technology enterprise and national high-tech enterprise. The main products are lead, antimony, silver, indium, zinc, etc.

In the company's indium zinc smelter, the volatilization rotary kiln process is adopted. During the operation of the volatilizing rotary kiln, the centrifugal effect is formed, and the reaction conditions are very intense. The refractory bricks in the kiln need to withstand the abrasion, erosion, peeling and thermal shock of the materials. Recommended by our company, SA spinel brick of our company is used in the volatilizing rotary kiln, which is built in high temperature zone and cooling zone, and put into production in February 2007. The service life of SA spinel brick is up to 246 days, creating the best record of refractories in the same type of rotary kiln.
