Ball Mill Liner components: Our ball mill liners solutions can be fitted with MultoMet composite lifter bars, shell plates and head plates. The MultoMet range utilises Hardox 500 wearresistant steel, attached to the leading edges of the lifter bar array and embedded within shell plates and head plates, ensuring maximum abrasion and impact resistance.
The Bond Ball Work Index Test determines the resistance of ore to grinding in a ball mill, expressed as a work index kilo Watt hour per ton (kWh/t). The work index is then used to calculate the specific energy requirements for sizing ball mills or determining their throughput for a target grind. Sample Requirements: 10kg

Most rod mills used in mineral processing are of the overflow discharge type as illustrated in Figure Centre peripheral (Figure ) and end peripheral discharge mills (Figure ) are also in feed end is generally fitted with spout feeders, scoop feeders, double scoop feeders or drum feeders.
The standard Bond Rod Mill Work Index test procedure is firstly to stage crush the feed to pass mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond rod mill. A Bond rod mill is by, with wave liners (of a form described by Bond), which runs at 40rpm and tilts as described below.
