For the preparation of limestone to feed the rotary kiln or shaft kiln, it is necessary to achieve a specific grain band. In particular, the very low fines content and the negligible amount of oversize grain of the DRC crusher are of great importance for the energy-efficient treatment of limestone for the firing process in the rotary kiln or shaft furnace.
CRUSHING LIMESTONE
AS MUCH COARSE GRAIN AS POSSIBLE
In particular, in the production of cement, where a coarse-grained limestone is needed in the shaft furnace or in the rotary kiln, the process property of coarse-grained crushing of the DRC series is of high importance. This saves costs for investment and maintenance, as well as the energy required to operate another crusher and additional conveyor belts.
The mechanical synchronization of the rollers ensures that the cubic grain shape is achieved. Synchronization positions the tools continuously with each other so that the geometric configuration produces a cubic grain shape. Likewise, an efficient feed of the material is achieved.
The hydraulically adjustable crushing gap ensures maximum process control. This allows the required grain sizes to be set efficiently and precisely.
