'square mill' (3,2m indiameter by 3,06m) can be adequately repre-sented by a single perfectly-mixed segment and, because of this and the high ratio ofdiameter tolength in the author's experimental mill, the same simplification wasadopted intheworkreported here. EXPERIMENTAL DETAILS The experimental work onwhich the model of the autogenous mill

Autogenous Grinding Explained. Mill length was the primary variable investigated in an autogenous pilot mill circuit. The 5-½' diameter mill had both pebble ports and ½" wide slotted grates. The plus ½" mill product was crushed in a cone crusher and returned to the mill feed along with the minus ½" plus 4 or 6 mesh fraction.

AUTOGENOUS MILL FEED PREPARATION TO REDUCE UNIT ENERGY CONSUMPTION ABSTRACT The through-put and energy efficiency of an autogenous (AG) grinding mill are adversely affected by variability in rock size and rock competency. This applies to both fully autogenous and semi-autogenous (SAG) grinding circuits.

Improving Autogenous/Semi-Autogenous Grinding Performance and Energy Efficiency with Optimised Pulp Lifter Design S Latchireddi1 ABSTRACT The comminution process indicates that the most energy-efficient comminution system would be one where the particles leave the breakage field as soon as they reach product size. Contrary to the free falling

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in .

The effects of temperature on autogenous grinding can be immediately divided into rheological effects and mechanical effects. The rheological effects are a result of the substantial increase in the viscosity of water as the freezing point is approached. The change in apparent slurry viscosity which results from changing temperature is shown in Figure 1.
