Assuming an ore where the solids have a specific gravity of 2.6, one ton of solids as 30% solids (70% solution) will occupy 86.7 cubic feet, while at 50% solids will only occupy about half that space, namely, 44.31 cubic feet.

Gelatinization occurs by mechanical means such as grinding, pressure, and by hot water. Soft feed at an environmental temperature of 25°C can be brought to a temperature of 85°C by the addition of 4 to 6 percent moisture from steam. Frictional heat due to passage of feed through the pellet mill adds 2 or 3 degrees of temperature.

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the product …

Size of feed material will determine the table settings. Pulverized rod mill pulps for gravity recovery tables should not exceed 65-minus to 100-minus 95% except where specific gravity, size, and shape will allow good recovery.

THE STANDARD MODEL KNELSON CONCENTRATOR The standard model KC (Figure 1) is a centrifuge that develops 60 g's and classifies a feed of 6 mm or less by specific gravity. The feed is introduced to the concentrator by gravity through a vertical tube to the base of the rotating bowl.

Feed Speed (feet per minute) x Depth of Cut (inches) x Kerf (inches) x Specific Gravity x 100 ÷ 144 ÷ Arbor Drive Efficiency (percent) x 100. Note: Specific Gravity: Douglas Fir = .45, Oak = .60, Southern Yellow Pine = .47, Spruce = .37, Oak = .60

involves the use of methylene iodide (CH2I2) which is diluted with acetone to reduce the specific gravity (SG) of the liquid phase to the target SG. With an SG of 3.3, the range of HLS testing using methylene iodide can be from 3.3 to 0.8 (i.e., the specific gravity of acetone), which far exceeds the requirements of most mineral systems.

A specific gravity of 1.39 was calculated, but the specific gravity value was to low for the K -chart as indicated on Figure C-6. So specific gravity of 2.60 for a temperature of 20 degrees was chosen instead. Lastly, Figure C-7 is a control chart and value that were used for the sample calculation to solve for percent finer.
