Metal slag processing // REMONDIS´ Lippe Plant

Practically all of the metals contained in the slag can be recovered. Go to recycling process. The special feature of LEGRAN’s metal slag processing system at the Lippe Plant is the way the material is treated. The slag and spent refractories need to be pulverised before they can be processed and this job is carried out by a rod and ball mill ...
