The HIGmill™ comprises a mill body, shaft with grinding rotors, shell mounted stator rings, gearbox, and drive. The grinding chamber is filled up to 70% with inert ceramic grinding media beads. Rotors stir the charge and grinding takes place between beads by attrition. The number of rotors (grinding stages) depends on the application and can ...
The relative 'efficiency' of horizontal grinding mills compared to other comminution equipment is often debated, and efforts to improve the energy efficiency of these mills is an ongoing area of attention for process engineers. The discharge arrangement design affects the material transport characteristics within a horizontal grinding mill.
Review of 11 mills showed the following results. They used kWh/t of mill. throughput as a bench mark given that they were grinding to a mill exit of 1800. cm2/g. All mills were running at 55% to 75% of critical speed. Practical results: Azergues. 100% > 72% of the charge (= 30% filling à %). Throughput 100% >80%.
