High Recirculating Loads In Ball Mill Circuits
Quality Mining Ball Mill Ceramic Ball Mill . Mining Ball Mill Large Discharge Opening Mineral Ore Mining Ball Mill Ball Milling Equipment High Return Iron Ore Mining Ball Mill Grinding Efficiency Ball Milling Machine Intermittent Mining Ball Mill Small Capacity Dry Grinding Ball Mill 1500 4500 Ball Grinding Machine Mining Ball Mill for Gypsum Limestone Iron Ore Industrial.High capacity (short retention time) Sensitive to feed composition (critical size material) Semi-Autogenous Grinding (SAG) Mill. Wet or dry Higher capacity than A-G mill grinding Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed plus 4-12 ball charge (ball dia.100- 125 mm) High capacity (short retention time).Schellinger's calculated ball mill efficiency, in dry or wet ball mill grinding, ranges between 10 and 19 , with the higher figure occurring at the optimal mill loading. In terms of the Brace and Walsh surface free energy of quartz, his results give a ball mill efficiency that is less than 0.5 .With ball milling tanks of agate, nylon and porcelain etc. for pumping vacuum). The capacity of vacuum ball milling tanks is not over 250ml. Maximum charge of ball milling tank three fourths of the cubage of the tank (including milling ball). Granularity of materials fed Soft materials ≤ 10 mm other materials ≤ 3 mm.
