PHB Weserhütte (PWH) have built and recently commissioned two circular stockpile systems which are used to stack, homogenize and reclaim raw coal for Gewerkschaft Sophia Jacoba in Hückelhoven, Germany.

The PWH circular stockpiling system with its careful material reclaiming properties was chosen after an in-depth study of all characteristics of known systems such as rectangular storage areas with different stacking systems and various methods of reclaiming working on the principles of drum or bucket wheel reclaimers.
