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
Lots of cubical grain for the rotary kiln or shaft furnace
AS FEW LOSSES AS POSSIBLE
AS MUCH COARSE GRAIN AS POSSIBLE
The gentle crushing process produces only a small proportion of the smaller fractions. For that you get more coarse grains. Decisive for this effect is an especially for this application adapted crushing tool that is tuned for interaction with the opposite crushing roller.
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.
CUBIC COARSE GRAIN
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.
