Equipment · Trommel Screens

Separate fines.
Capture spec product.

Rent a mobile trommel screen anywhere in the United States. Sort fines, oversize, and contamination from compost, mulch, soil, and aggregate — in one pass, on-site, with the discharge stockpiles set exactly where you need them.

01 / How a mobile trommel screen works

Mixed material in. Spec product out.

A rotating drum tumbles material across mesh panels. Fines fall through first, mids through a coarser section, and oversize runs out the end. Three clean stockpiles from one machine, one pass, one operator.

FEED FINES MIDS OVERSIZE TROMMEL DRUM · CUTAWAY ROTATES
  • 01

    Load the feed hopper

    Loader or excavator drops mixed material into the elevated feed hopper. Apron belt meters it onto the rotating drum.

  • 02

    Drum rotates & tumbles

    The drum spins at 12-18 rpm. Tumbling action breaks up clumps, exposes every particle to the mesh, and keeps the screen self-cleaning.

  • 03

    Fines & mids sort by mesh

    Smaller particles fall through the mesh in the first section to the fines belt. Mid-size product passes a coarser mesh to the mids belt.

  • 04

    Oversize discharges off the end

    Anything that doesn't pass either mesh (sticks, rocks, contamination) runs out the end of the drum onto the oversize stockpile.

03 / What you can screen

Eight materials. One machine.

Swap the mesh panels and a trommel adapts to nearly any screening job. These are the materials operators run most.

01

Compost

Finished compost separation. Pull plastics, sticks, and stones; produce clean, baggable spec.

Mesh: 3/8" – 1/2"
02

Topsoil

Screen out roots, stones, and clumps to produce clean planting soil for landscape suppliers.

Mesh: 1/2" – 3/4"
03

Mulch

Color-grade fines, captured oversize back to grinder, spec product to bagging or bulk delivery.

Mesh: 1/2" – 1"
04

C&D fines

Recover dirt and fines from demolition debris. Reduce landfill tonnage and recover usable material.

Mesh: 1/4" – 3/4"
05

Crushed concrete

Pair with a concrete crusher to size aggregate to spec for road base, structural fill, or rip-rap.

Mesh: 3/4" – 4"
06

Sand & gravel

Quarry secondary screening, river-rock sizing, decorative aggregate for landscape supply.

Mesh: 1/4" – 2"
07

Wood waste

Post-grinder sizing for biomass fuel, animal bedding, and boiler-grade chip specifications.

Mesh: 3/8" – 2"
08

Soil remediation

Remove contamination, debris, and oversize from impacted soils ahead of treatment or disposal.

Mesh: 1/4" – 1/2"

06 / FAQ

What operators ask first.

Standard inventory: 1/4", 3/8", 1/2", 3/4", 1", 1.5", 2", and 4". Mesh swaps take approximately 30 minutes per panel. Tell us your target product spec and we'll ship the right mesh with the machine.
Quick rule: under ~150 yd³/day or tight site access, go with the MIDI. Production volume, multiple fractions, or continuous yard operation, go with the TROM 512. The 512 adds a third discharge belt standard, a 68 HP Cat engine, and a 3.2 cu. yd hopper. Share your daily volume target with the quote and we'll size it.
Yes, with caveats. Saturated material reduces throughput 30-50% because wet fines clog mesh openings faster. Frozen material can ball up inside the drum instead of tumbling apart. In both cases, coarser mesh and slower feed rates help. We'll factor moisture into the quote estimate.
The TROM 512 includes three discharge belts standard: fines, mids, and oversize. The MIDI ships with two standard; a bolt-on stacker adds a third fraction if needed. Both models stockpile directly under the conveyors, so a separate radial stacker is only necessary if you need larger stockpile capacity or radial sweep.
Trommels excel on organic, fibrous, and sticky material (compost, mulch, wet topsoil) because the tumbling action self-cleans the mesh. Vibrating screens work best on dry, granular material (crushed stone, sand, dry aggregate) where high-frequency vibration separates efficiently. If your feed is damp or stringy, a trommel is almost always the better choice.
Plan for 70' × 40' for the MIDI and 90' × 50' for the TROM 512. That accounts for the machine, a loader approach to the hopper, and discharge stockpile areas. Tighter setups are workable; share constraints in the quote.
All three. Most projects come out ahead on a weekly or monthly rate once delivery, setup, and mesh selection are factored in. We'll quote whichever duration works best for your scope.
