Abstract :
The developments in drive technology enable us to consider the use of AC drives also for the kiln main drive. Although a lot of applications with AC kiln drives are running throughout the world successfully since 1987, a lot of people feel that the kiln main drive should be equipped in DC technology. The paper compares the AC and DC drives. The advantages and disadvantages of both drives are addressed. Besides investment costs, major characteristics and also operation and maintenance costs are listed
