MudMixer MMXR-3221 Heavy-Duty Portable Multi-Use Concrete Mixer

The MudMixer MMXR-3221 Heavy-Duty Portable Multi-Use Mixer is designed to make mixing and dispensing bagged concrete, mortar, and compatible construction mixes faster, cleaner, and more consistent. Its continuous mixing design combines dry material with an adjustable water supply as it moves through the auger, allowing mixed material to be delivered directly where it is needed.

Powered by a 120V electric motor, the MMXR-3221 eliminates the need for a gasoline engine and provides convenient operation anywhere a compatible electrical and water supply is available.

Continuous Mixing System

Unlike traditional drum mixers that require individual batches, the MudMixer uses an auger-driven continuous mixing system. Dry mix is loaded into the hopper, where the integrated bag opener helps simplify loading.

A fully adjustable water control dial allows the operator to regulate water flow to achieve the desired mix consistency. The auger then moves and mixes the material before dispensing it through the chute.

The electric drivetrain is designed to process up to approximately 40 bags of mix per hour, helping improve productivity on larger projects.

Heavy-Duty Portable Construction

The MMXR-3221 features a body constructed from 14-gauge high-strength steel and a frame made from 1-inch steel pipe for demanding jobsite use.

Its Marathon flat-free tires provide convenient mobility without the downtime associated with pneumatic tire punctures.

A 330-degree pivot system provides flexibility when positioning the discharge chute, allowing mixed material to be directed more precisely around the work area.

Convenient Cleanup

An attached secondary hose provides convenient access to water for cleanup after mixing. The electric components and connections are designed with water resistance in mind, while auger guards help improve operator protection during use.
