Clarage's years of fan knowledge gives us the unique ability to design a fan for any coal mill application. Be it our HMF, special coal mill exhauster or a simple backward inclined impeller for general ventilation, we have it all. With over 140 years of experience, we have been installing fans in coal mills since the beginning.
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.

One of the most critical variables in the cement ball mills is ventilation. A mixture of hot and recycled air would deliver and dry the powder in a cement ball mill as a pulverizing system. Thus, ventilation in this system can have a significant effect on the production process.
1. Introduction. Ball mills have been widely employed in many industries, such as mineral, cement, food and pharmaceutical industries. During the industrial processes, ball mills are employed not only for grinding, drying and mechanical coating duties, but also for open and closed circuits [1], [2], [3].For example, in the mineral …
Operation and Elements of a Closed-Circuit Ball Mill System . Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media andlined with lifting liners . The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding ...

One potential method is strengthening the internal and external ventilation of the grinder. Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature.
With a ball-bearing motor and cupped fan blades, these fans last longer and focus airflow better than economy fans. High-Output Beam-Mount Fans Generate at least 25% greater airflow than economy and premium fans.
