— A mechanical classifier often receives its feed from a ball mill and produces (1) finished material which overflows to the next operation and (2) sand which returns to the mill for further size-reduction. ... which includes the volume of a ton of solids plus the necessary volume of water to make a pulp of the particular specific gravity desired ...

For the full scale mill, specific power is multiplied by the feed rate to get the net mill power. This must then be increased by the anticipated mechanical inefficiencies (bearing/gear friction losses and possible speed reducer losses) as well as electrical losses, in order to arrive the gross mill power. ...

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 …

 — The design feed rate was established using the AMIRA P420 BCC Gravity Model to simulate gold recoveries at different gravity throughput rates. The mill water balance constrained the gravity circuit capacity to 500 t/h, and the capacity of the existing cyclone feed pump further restricted the gravity feed rate to 360 t/h.

Note: Water movement through the test container may be used as an alternative to use of quiet water. Table 2 shows the water stability of ground and unground standard feed (see Table 1) and the effects of replacing 5 percent of rice bran with various organic and mineral materials suggested as binders.

Ball-Rod Mills, based on 4″ liners and capacity varying as 2.6 power of mill diameter, on the 5′ size give 20 per cent increased capacity; on the 4′ size, 25 per cent; and on the 3′ size, 28 per cent.

Both mill discharges join together at the cyclone feed sump and are pumped to the cyclones. The overflow is to be 60% - 200 mesh (74 microns) with a minimum of 40% solids by weight. The underflow becomes the ball mill feed. The specific gravity of solids is 2.9, and the estimated circulating load is 225%.

 — In this equation, E is the specific energy required for the grind, and F80 and P80 are the sizes in micrometers that 80% of the weight passes of the mill feed and product respectively. The parameter Wi, known as the work index of the ore, is obtained from batch bench tests first devised by Bond (1961).

Specific gravity is the ratio of the object's density to the density of water, i.e.: begin{equation} text { Specific gravity }=frac{text { Density of an object }}{text { Density of water }}nonumber end{equation} The units cancel out in the ratio. Therefore, the specific gravity is a unitless number.
