Our 12v “Shaker Table” performs just like the big tables but ….. It can be used ANYWHERE.

Because it is a self contained, highly portable recirculating system, it works in the Shop, at Home, or in the Field!

The Deck Plate is made of a special Aluminum Alloy that has been produced by State of the Art Technology that machines V-Groves into its surface by a Computer Controlled Lathe to produce a consistent depth assuring proper material flow.

This new deck will not warp and will wear hard for many years.

The table has multiple adjustment points that enables the operator to set the material flow for any type of material cut they wish. It is “User Friendly” and, after a relatively short learning period, He or She will become proficient at separation and classification control. (Using a shaker table is as much of an Art as it is a Science). Material should be screened to 16 mesh for best results.

There are 4 discharge ports. The first collection trap will be mostly Gold with some black sand, the second will be black sand with some Gold, the third will be almost all black sand and the fourth will be all Gangue.
