After a lot of procrastination about building a decent gold processing unit to run a decent amount of dirt, I have been talking to another fellow prospector at work the last week, and I have decided to build a trommel.
I was originally going to build a small scale one to play with on the weekends, but decided today to upgrade it to a trailer mounted unit.
It will be grand for a home built job.
I plan to use a 44 gallon drum as the base of the trommel, and splice a stiff mesh into it.
for the problem of loading it due to being mounted on a trailer, I'm going to have a conveyor belt system so it can still be loaded by shovel to comply with the " no mechanical digging " rules.
the conveyor Will probably be driven by a hydraulic motor and maybe the trommel as well to be able to have enough torque to rotate the drum.
the hydraulic pump will just be one similar to that on a truck for a hiab crane. And an inline valve to control the speeds .
A lot of the hydraulic items I can source through work.
it will all be designed to run off a 12v so I'm not carrying generators or anything, just a pump for water.
Both the sluice and the conveyor will either be detachable or hinged so they can fold away during transport and be simple to setup again when on site.
This will also be a budget build, utilising as much scrap and spare parts as I can to help fly under the radar of the minister of finance lol.
Below is my first sketch of the plan...
