Bill's Gold Trommel Page

                                  Here are the Small Trommels.

                                             Four very different trommels, two gas powered and two battery powered.

                                       This is the first one we built and it worked very well , it has a small Keene A51A sluice under it.  It is
                                        powered by a small chain saw engine with plenty of gear reduction to get the slow 20-30 RPM. 

                                       Then came the twin engine model, that didn't double our gold production ;-) so we dropped back to....

                                        The new Weedeater powered version. The internal gear reduction of this motor eliminated lots of parts.
                                        This cost less to build, improved realibility, has less mainenance, it used the A51A sluice too.

                                                                                  Weedeater Gas Powered Trommel

                                        To enhance fine gold recovery on this trommel I put a Keene A51 sluice under it, it is much wider than
                                        the A51A and  it recovers fines and small nuggets very well. The orginal 3/8 trommel screen has a 1/4
                                        inch screen inserted in it for just fine and minus 1/4 in material. Note the metal cover over the rear sprocket
                                        and one over the rear of hopper to protect barrel sprocket from rocks/dirt which can cause lockups.
                                       .Great Saftey addition too. These larger Trommels weigh in at around 90 lbs are 5 ft. long and 3 ft. high.

                                                                                           Battery Powered Trommel

                                            Then I wanted to see if I could build a battery powered trommel with accompaning battery powered
                                        water pump.  Here is my 8 in bat powered trommel, very quiet in operation,  and it exceeded all my
                                        expectations on my field test. It uses a Keene A51A sluice, here it is running a recirculating test in the yard
                                        for over an hour with no problems. They  pulled 10 amps total, trommel 1.5 amps and pump 8.5 amps,
                                        the pump is a Rule 2000.  This trommel is 36 inches long and 24 inches high and weighs in at 30 lbs.

                                                                                                  Our New Baby

                                        Now the latest member to the trommel family is this little 6 inch barrel, battery powered unit. My Gold Gal
                                        wanted a tiny trommel to use at camp for those buckets of dirt we bring back.  This little baby comes in at
                                        23 lbs, and is 26 inches long and 22 inches high.
