As few losses as possible

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 CST crusher are of great importance for the energy-efficient treatment of limestone for the firing process in the rotary kiln or shaft furnace.

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 CST series is of high importance. Depending on the size of the feed grain, even a crushing stage can be omitted in the comminution process since a comminution ratio of up to 1:7 can be achieved. 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.
