The three spare bearings for the roller press seemed to be in a better state, but no one was sure. When fractures occurred on the roller surface, the high-pressure grinding roller press was dismounted for welding repairs and the large 4-row oil lubricated cylindrical roller bearings were taken out and labelled "unreliable" spare parts.
