What should be paid attention to in the dry grinding of iron oxide scale by ball mill

The invention relates to a method for the agglomeration of ironoxidecontaining residual materials in particular scale and mill scale wherein the residual materials and paper sludge are dried and ground and agglomerates are produced by hot briquetting from a mixture of the residual materials and paper sludge so processed In this manner it is possible to produce mill scale briquettes of
