Hi all,. I just bought a Mad Mining drywasher,. I believe this is a great machine !! Revolutionary ? ,. yeah, I believe it is .
I'll take this story back about a month or so,...I made it out on a one nighter,.. My friends , Jerry & Walt where to work the P.L.P. booth at a Temecula Valley Prospectors event ,held on the sleepy bear mine [active commercial placer mine], near Randsburg Ca. ,. Great event!!
As planed ,. we meet Bill of Mad Mining there ,. about 3:00 we headed on over to Bill's camp . I'll digress a bit here ,.. Jerry , just a week or two before ,. had told me about this crazy "new" drywasher he had just seen/used . Try as he might ,. he described this machine ,. "uses a electric motor ,. but ,.no you do use a gas blower" ,.. finds lots of fine gold ..""?? Hell,. I'm game , I'll throw some dirt on a man's "new idea".
At camp ,. we meet a few others ,. and Bill had a few of his "new idea" machines there,. and there was dirt to be thrown ,.
The material To be worked,. could be described as loose sand/gravel ,. shovel ready, for the most part . On an incline ,. we "toed in" the drywashers and started shoveling ,... believe at a +1 yd/hr rate ,. most runs where near half yd or so. The machines ran great , the fluid bed looked great . Hell,. even the dust stayed low ,. maybe from the lower amount of air used ,and/or the high frequency vibration ,. which feels more like a "hummm.." anyway it's a nice feature .
And yes ,. we found a bit of gold ,. Infact I'd say we found a lot of fine gold . But the area has a lot of fine gold ,. and one can always get some ,. but not a lot .

The tray & riffeles & other Au. traps . The tray is nice , tall sides ,. easy to remove ,. you can even just idle down the blower, pull the tray , dump it , slap it back in and away you go . In the first pic . you can see maybe one "revolutionary idea" ,. it's for sure some thinking "outside the box". The perforated plate is over the cloth ,. this should save the cloth from wear a bit ,. but each hole acts like a mini gold trap ,. well black sand for sure .

This unit uses a 12v motor for vibration . It runs at 4500 rpm [?] and draws 1.2 amp at start up and runs at .5 amp . this "high frequency" vibration, maybe the key to fine gold recovery ?? this motor is mounted under the hopper ,. and I'm sure it helps with the problem free feed .
This unit folds up nice and tight , and easy set up with four pins ,. and has 3 settings for hopper/feed rate . so., all around a great machine
