TMX 1500 Forced Action Concrete Mixer

$4,016.50

The Collomatic TMX 1500 is a compact, automatic forced‑action mixer built for contractors who handle heavy pre‑bagged materials every day. Its high‑capacity drum mixes up to five bags or 32 gallons per batch, while three low‑speed, angled mixing arms deliver a consistent, high‑quality mix and keep your crew productive from first pour to last.

  • High-capacity mixing: Handles up to 32 gallons, or roughly 5 bags of heavy pre-bagged material, in a single batch, so you can move quickly on larger projects.
  • Powerful motor: A 3.6 hp motor driven by a 240 V power supply delivers the torque you need for dense mixes such as mortar and concrete.
  • Forced action mixing system: Three precisely angled mixing arms rotate at a controlled speed to thoroughly blend heavy materials and support a consistent result from batch to batch.

Concrete Mixers FAQs

It comes down to what you're mixing and how much of it. Thin, flowable materials like self-levelers and grout do well with a handheld paddle mixer. Thicker, stiffer mixes like polymer mortars and repair concrete call for a forced-action drum or cone system with an auger. For smaller batches or frequent material changes, an auger mixer or handheld paddle keeps things simple. Check the individual product specs to match paddle style to your mix.

A double paddle mixer uses counter-rotating paddles for a faster wet-out, better control in heavy mixes, and less strain during long pours. A single paddle mixer is lighter and easier to maneuver, a solid fit for standard mortars and grout.

Yes, with the right paddle and a low RPM to keep air out of the mix. Forced-action drums and cone systems are especially well suited to resin-bonded sands, since they shear the material evenly.

Rinse the paddle or drum right after use and never let material cure inside it. Check paddles and augers regularly for wear or bent blades, and replace them if the mix starts coming out uneven.

If you're mixing often or working with specialty materials, buying makes sense. For an occasional or one-off pour, renting is the more practical route. Reach out if you'd like to rent a mixer for your project.

Add powder gradually into water and keep the RPM low to limit dust. Enclosed or cone systems help with higher-capacity, lower-splash batching, and working in a ventilated area with a wet-mix technique also goes a long way.
