Description
Continuous auger flighting draws dry bagged concrete through a metered water spray tube to churn out mixed material on demand. The Mud Mixer MMXR-3225 Continuous Mixer uses an electric drive motor to mix up to forty bags of concrete per hour. Fence crews set posts fast. Running dry without water will pack aggregate inside the auger tube.
Heavy fourteen-gauge powder-coated steel forms the main hopper and auger barrel to resist rock impact. A sealed 0.75-horsepower electric gearmotor operates on 120V single-phase current drawing 10.5 full-load amps. A solid steel continuous auger routes material through a metered water manifold into an adjustable chute. The mobile chassis rides on two flat-free tires with a front caster. Net unit weight totals 145 lbs with dimensions measuring 24 inches wide by 66 inches long by 36 inches high.
Key Features of Mud Mixer MMXR-3225
Fence contractors and post setters buy Mud Mixer MMXR-3225 units when commercial concrete mixer pricing requires continuous on-demand output. This machine mixes bagged concrete, fence post concrete, mortar mix, and dry-pack grout.
- Hopper holds dry cement bags while the continuous auger mixes on demand.
- Integrated water valve meters exact fluid flow into the mixing auger barrel.
- High-torque 0.75-horsepower electric gearmotor operates on standard 120-volt household circuits.
- Adjustable discharge chute directs wet concrete straight into post holes without wheelbarrows.
- Flat-free transport tires glide over mud, sand, and lawn grass without flat tires.
- Secondary hose bib connection allows fast tool washdown and bucket filling on site.
- Electric control box includes instant forward and reverse auger rotation switches.
Continuous Auger Bench Torque Diagnostics
Bench testing confirms auger shaft speeds hold at 60 RPM under continuous dry bag feeding at one bag per minute. Motor current draws 8.8 amps during standard gravel concrete flow, peaking at 11.2 amps under heavy sand mortar feed. Motor casing temperatures level off at 136 degrees Fahrenheit after sixty minutes of continuous mixing. The internal auger flighting shows zero deformation under coarse gravel pressure. Water manifold check valves prevent backflow into the garden hose connection during operation.
Jobsite Usability Auger Upkeep Procedures
The low hopper height lets one worker drop dry concrete bags across the splitter without shoulder fatigue. The swivel chute directs wet concrete straight into fence holes without messy wheelbarrow shoveling. Do not buy this machine for bulk aggregate gravel mixing without pre-bagged concrete.
- Flush the auger barrel with water for two minutes after finishing each pour.
- Inspect the water flow control valve for sediment blockage each morning.
- Check auger barrel seals for grout leakage after fifty field hours.
