Mini-Mobile Gold Processor. One of our unique designs combines a sluice connected directly to the hammer mill outlet. The hammer mill is a standard 16″ x 12″ powered by a 22 hp gasoline engine and will accept a feed size up to 2-1/2 inches. This makes for a portable and cost effective small production machine or robust sampling system.
