30 Second Briefing
CEMTEC and Eirich have formed a grinding alliance that combines CEMTEC’s primary tumbling mill technology with Eirich’s TowerMill for fine and ultrafine grinding in mining and mineral processing plants worldwide. The partnership targets flowsheets where large SAG/ball mills handle coarse feed and vertical TowerMills close circuits with hydrocyclones for sub-100 µm product, offering a single-source package from primary to ultrafine size reduction. For engineers, this could simplify mill selection, liner and media strategies, and power-draw optimisation across the entire comminution circuit.
Technical Brief
- CEMTEC contributes design and supply of large-diameter tumbling mills for primary ore grinding duties.
- Eirich brings TowerMill vertical stirred mill technology, focused on fine and ultrafine mineral grinding.
