Welcome to
Dry Mining Equipment.
We are based in Arizona, USA, specializing in the production of innovative desert mining.
MAG-ZIP Technology Co-Developed with Magnetic Systems International's No Contact Drum Separator
Looking for a solution to the "Black Sand" problem when mining dry placer gold? You have come to the right place! The MAG-ZIP rapidly separates magnetite from a continuous flow of dry placer gold concentrates, FIRST, before doing anything else!
It lightens the load by 30-50% in just a few minutes! The volume for the next step is smaller and lighter. The new MAG-ZIP technology saves enormous amounts of time and cleaning up concentrates has never been easier.
NOTE: The MAG-ZIP precludes "bird nesting" by twigs/leaves in the hopper by screening the feed to -12 mesh which runs fast, smooth, and more selectively. Besides, the vast majority of detrital magnetite is ground by nature to be below 12 mesh. Even the common lead bird shot is removed by the 12 mesh screen.
The MAG-ZIP now (2020) uses weak magnets which are much more selective than strong magnets. The magnetite can be re-run to check for any stray particles, and re-runs are even faster! Two passes removes ~96% of the magnetite, and two quick re-runs makes sure it is pure magnetite. All four runs process 1/2 gal in 2 minutes!
Think you don't have enough cons? We run 30-40 yd/day and still only bring home 1 tray, about 1/2 gal. It saves us over an hr of time with the clean up!
Vibra-Bucket
Shakes Your Screens, so you don't have to!
The Vibra-Bucket assists the otherwise tedious screening of fine mesh sands; it makes this task easier! It has a 30W industrial vibrator mounted inside a 5 gal heavy duty steel pail with a further reinforcing bottom board. A special flat rimmed (short) 3.5 gal plastic bucket fits above the motor to hold the screen and catch the sand. The flat rim gets the vibration transferred from the metal pail. Sections of rubber tape inside the steel pail rim provide a snug fit with air gaps, so that there will never be a "stuck bucket" due to a vacuum seal. The base plate keeps the pail bottom flat by preventing the rim from digging into the ground and dampening the vibration.
When tested with a 8 lb (1/2 gal) 3/1 mix of -12M/+12M actual placer sand it delivers 97% in 1 minute. The speed controller provides turning down the force to MEDIUM range where it will screen about twice as fast as maximum. In this way, sand stays closer to the screen which allows more particles to find the holes. Full force is needed at first to help stir a heavier load at start, but shallow batches are recommended. .
A video shows how a gallon of waste magnetite was re-screened to -12M and it goes through in about 15 seconds and the added weight dampens the sound!
The vibration motor is 115V AC. An inverter is available as an option to work with 12V DC source in the field.
Tilt-a-Bucket Handle
The handle/ring slips over the lower end of a 5 gal bucket and slides up a couple of inches for a snug fit. The bucket may now be lifted by two points, the bail and the lower handle. It provides a much better way to handle the weight of a full bucket and simultaneously have complete control to tilt and pour or empty completely. It is manufactured with all aluminum parts to not add any appreciable weight to the assembly. The handle is configured with a large enough opening against the bucket side that even a large hand with a glove may fit around the handle. It is easily removed and transferred from one bucket to another. The unique design of the bent edges of the handle provides strength and smooth edges for handling. Slight adjustments may be made by hand to compensate for the subtle differences of bucket diameters produced by different vendors.

Wherever buckets are used (paint , oil, water. rocks, feed, debris etc) these handles can assist.
