Hydraulic drives for clinker cooler roller breakers

The author considers the design of a roller breaker equipped with a hydraulic drive for the purpose of improving the operating reliability of the clinker crushing and grate cooler system in cement factories. In contrast to the electric drive, the hydraulic drive offers essential advantages for a crushing process using slow-rotation rollers, including the flexibility to adapt to higher speeds. In addition to the particular drive characteristics, a number of improvements in process technology and economy are achieved, proving the roller breaker´s superiority over the conventional hammer crusher. All of these features were implemented with the aim of increasing the reliability of cooler/breaker operation, that is, minimizing kiln stops caused by this area
