    According to [26], when grinding in a ball mill, the reduction in size occurs according to three mechanisms of fragmentation: abrasion, splitting, and

  • A Successful Model of Cost Reduction in the Melt Shop

    Today’smost competitive mills are discovering that they can positively control and influence more than 25 points of value across the entire mill process. These include slag engineering, energy consumption, yield improvement, refractory consumption, and equipment utilization. These profit points live at the center of


    Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost.

  • Ball Mills and Ball Charging Bulk Handling

    Grinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level. The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the size reduction and distribution required in the discharge.

  • Addition of pebbles to a ball-mill to improve grinding

    2017-4-1 · The control of ball-mills is relatively simple in comparison (i.e. addition of balls to maintain power and control of the cyclones and pulp density). Pebble-milling is used on some mines for secondary grinding, to reduce operating costs. However, the availability of pebbles is essential and pebble storage is required.
