- I was looking to build a trommel since before I did the GOLD sluicing video. What is a Trommel? Well - its a rotating drum that is its basic form is a filtering system. For example, excavation contractors may screen their site debris into two fractions; a saleable topsoil for farms, nurseries and site-work, as well as cleaned rock for aggregates or landscaping work. This allows the contractor to resell their waste, instead of incurring the cost of sending it for disposal.
The same principle applies to the production of compost, sand/gravel, lumber mill by-products and municipal waste.
Trommels are also used in the recovery of gold from mineral rich soils. The dirt is broken up by high pressure water jets before entering the trommel, which breaks up the dirt further and outputs the rocks and stones while depositing the gold fragments in special plastic mats.
Partnering up with long time RC Adventures viewer, Mike, aka "MAV",(www.youtube.com/MadAddVent)
we have come up with something incredible. This project has been secretly being created for several months, and is the brainchild of MAV from the beginning. and now we are able to mine and filter Good Pay Dirt, from the Debris!
Once again a special thanks to Mike Aka MAV for helping make this RC Mining adventure possible! make sure to check out his YouTube channel! He has some great videos, tips and tricks for you to discover and enjoy! You may even want to Subscribe!
