Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today's global markets, expanding mining groups are trying
Jun 15, 2017 · Moreover, since few quantities of solvent are used, substrate hydrolysis that occurs during MOF synthesis can be limited in ball-mills. Applications of ball-milling in various domains can be found in literature but it is at an early stage of development when it is applied to the synthesis of MOFs .

Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.
