Mobile and stationary processing combined.

The “Nordschwarzwald” (Northern Black Forest) natural stone plant was put into operation in 2006 after a construction period of 16 months. The plant’s design was a special challenge for Kleemann, as productivity was to be increased and optimum product quality guaranteed at the same time.

Magstadt is Germany’s most modern fully automatic crushing and processing plant and uses a combination of mobile primary crusher and stationary crushing and screening plant. Processing comprises three lines: pre-crushing and pre-screening unit, subbase plant, and high-quality chippings plant.

A mobile primary crusher located at the quarry face is used in the first processing stage. Bulk material quarried by blasting is fed into the crusher by a wheel loader. The limestone, which can have edge lengths of up to 1,800 mm, is reduced in size by the primary crusher to an intermediate product of grain sizes ranging from 0 to 300 mm. The crusher has a maximum throughput capacity of 800 t/h.

From the mobile primary crusher, the pre-crushed material is transported to the stationary crushing and screening plant via feed conveyors. In the secondary stage, the material is crushed by a Kleemann impact crusher SNH 14. Sophisticated feeding and crushing control is used here for the production of standardized final aggregate fractions. In the high-quality chippings plant – the third processing stage –, the material produced on the subbase line is refined to high-quality concrete chippings.

The final products are stored in 24 silos and can be blended to different mineral aggregate mixtures via two loading stations with a total capacity of up to 2,400 t/h. The loading stations in the Magstadt plant are equipped with a dust extraction system to ensure dust-free loading on trucks.
