Method for reducing the temperature of grinding cement. 1. Reduce the temperature of the clinker. ①Strengthen material management, avoid clinker with high temperature into the grinding head bin, and prevent red material from entering the grinding. ②Spray water in the cooler to reduce the clinker temperature. ③Spray water on the clinker belt.

In cement mills, ventilation is a critical key for maintaining temperature and material transportation. However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today. This investigation is going to fill this gap based on a newly developed concept named "conscious laboratory (CL)".
