A motorized drywashing machine is excellent for the production demands of a one or twoperson operation. Under ideal conditions, it is able to process up to about a ton of raw material per hour, which is the equivalent of what a mediumsized wet sluicing operation can produce.
A drywasher is a common desert mining tool for gold mining.. A drywasher is like a highbanker, [clarification needed] since it uses a motor and a form of sluice, but it has no need for drywasher operates by the use of air. By forcing air to flow up through the material as it moves down the sluice, the heavier materials, like gold, will stay at the bottom and get trapped by the riffles ...
