grain-size

These include ash thickness and grain-size and the availability of equipment.

Actions to take for ash fall? 2009

The average grain-size of rock fragments and volcanic ash erupted from an exploding volcanic vent varies greatly among different eruptions and during a single explosive eruption that lasts hours to days.

The finer the grain-size of the valuable minerals in the feed, the smaller the sluice inclination must be to prevent the slurry velocity from becoming too high.

14.1 Jig screen, hand-jigging 1993

Dimensions: inclination of sluice depends on mode of operation and grain-size of feed: 2° - 8° for semi-continuous pre-concentration of heavy mineral feed; 14. 8° in Bolivia for reprocessing of narrowly classified concentrates in intermittent operation.

14.1 Jig screen, hand-jigging 1993

Wet screening is a low cost, simple, quick and precise alternative for sorting feed material of medium to coarse grain-size.

13.1 Set of rigid screens 1993

The sampling procedure should not only include numerous different sample locations but should also ensure that the grain-size of the samples also vary, in that samples of the finer fractions and the fines are also collected along with the large pieces of ore.

Throughput/Capacity: very dependent on grain-size of feed

Kirschner gives the following design data for the piston stroke relative to the grain-size of the feed:
