The Mini-Max Trommel Wash Plant is the largest most efficient “mini” trommel manufactured in the United States.

This wash plant is a highly portable and versatile unit that can be towed behind an ATV. The unit has a wide stance and good center of gravity with good ground clearance due to the included ATV tires which are perfect for difficult terrain. The tow bar is removable by pulling a single 1/2-inch hitch pin. The Mini-Max can be easily set up and ready to run in minutes. The legs are fully adjustable in height to compensate for varying terrain & also to adjust material processing rates.

The standard Mini-Max can be disassembled without tools into its major components in under 1 minute to facilitate loading & unloading into/out of a standard truck bed or trailer. The all-steel frame is fully triangulated for maximum durability while still remaining lightweight enough to maneuver the unit by hand.

This Wash Plant is powered by either a Gas driven (Standard model) or a Diesel driven option or an Electric driven option is available as well as a “V” series model that includes a vibrating Pan Feed style hopper for the ultimate in feed rate washing and tuning ability (identical in design to the 159-V hopper, just smaller).

This Wash Plant is offered in two styles for either Gold Recovery or Diamond / Gemstone / Gold Recovery.

The gold recovery model includes a matching sluice box gold recovery system that is 6’ (1,829mm) long x 15” (381mm) wide. Different lengths are available upon request.

The Diamond / Gemstone / Gold recovery model replaces the sluice box with a matched to-size 12” (304mm) Duplex Pan-American Diamond Jig recovery system.



The Standard Feed Hopper (same style as supplied with the Standard Mini-Trommel) comes with a full spray bar system with a “pusher jet” for quick and easy processing of materials as well as excellent material washing.  It is fully removable with four 3/8-inch locking pins and also available is our optional quick-release 4-inch Dredge Adapter.  The removable Dredge Adapter is designed to the standard Feed Hopper.

We offer a wide range of Feed Hopper styles. Including the “Mechanical Feed Hopper” (shown in the image gallery) which is for use with small Backhoes and Mini-excavators.  This style hopper has a full “Grizzly bar” classification system for the raw material and a single spray bar on top that is fully adjustable.  This style is a down-sized version of the ones found on our standard 159 model Wash Plants.

Another Feed hopper option is our new “Clay-Buster” hopper (shown in the image gallery) which is designed for High clay environments and can be fed by shovels or buckets.

The 2-stage barrel is 8 foot in total length and 15 inch in diameter.  The “Scrubber” section of the barrel is 48 inch in length and is loaded with a full array of slurry “turn plates” (material lifting bars) as well as slurry dams, both of which enable excellent clay and cemented gravel break down and washing.  This unit has the largest and best working “Scrubber” section available for a unit this size and helps level out the material “surging” that is common with shorter barrels.

The screen portion of the barrel is 36 inch in length and is manufactured from perforated steel (punch plate) with the highest percentage of “open area” available to help produce some of the highest “Tons per Hour” numbers available to the open market.  Classification hole size is 1/2-inch standard with other sizing options available upon request.  The tail section of the barrel contains two of our “Nugget rings” for retention of oversized values.

The motor comes with a heavy-duty skid plate underneath.  The fuel tank is remote-mounted & comes with an inline fuel filter.  The heavy-duty positive chain drive system utilizes sealed unit bearings and is fully adjustable in tension both at the motor as well as the barrel.  The drive system is a variable 6-13 RPM design and is strong enough to process full loads at idle.

The water delivery system consists of an adjustable angle full-length spray bar inside the barrel that is easily removable by way of a quick-release pull pin and is fully adjustable in flow rate with its own gate valve.  The standard Feed Hopper also contains a perimeter spray bar that is also easily removable as well as adjustable in angle and also comes with its own gate valve for flow adjustment.  The Hopper spray bar also contains a “pusher” jet to aid in the consistent material feed when shoveling or feeding by the bucket.  The Hopper also has a quick-release safety cover to protect the spray bar from damage and provides a sturdy place to “bang” the shovel clean or rest a bucket.

This unit will easily process 3-5 full five-gallon buckets of material per minute so we felt there was no real need for a “bucket rest” feature in or on the Feed Hopper for this unit.  The water distribution box also has a connection for a washout hose.

The included sluice box gold recovery system measures in at 72 inches long by 12 inch wide and is more than adequate at keeping up with the feed rate associated with this Trommel Wash Plant.  Standard riffle design is a “70/30” mix of 3# Gratex (large expanded) and Hungarian style riffles that have varied spacing and angles to ensure great recovery percentages of values.  We can also custom-tailor the sluice recovery system to the specific recovery needs of your particular operation as well.

Also included with the sluice is one of our infamous 2′ long “Raised Slick-Plates” to provide a smooth flow transition to the riffles which increases recovery numbers.  The sluice comes with a full  square tube “ladder” style frame and fully adjustable legs to enable ease of adjustment of sluice angle.  When setting up for operation, the sluice can be mounted on either side of the Trommel unit with a single 3/8-inch grade 8 quick-release mounting pin which allows for ease of adjustment to almost any angle.
