How to Keep Your Concrete Mixer in Good Condition
Regular maintenance helps extend the working life of a concrete mixer, improve reliability and maintain consistent mixing performance. Since mixers operate with cement, sand, aggregate and water, cleaning and inspection should be part of every workflow.
The six mixers covered in this guide range from 80L to 100L capacity, with weights between 88kg and 145kg, meaning maintenance requirements can vary depending on the mixer design, transport frequency and workload.
Cleaning the Drum After Use
Cleaning the mixer immediately after completing a job is one of the most important maintenance steps. Wet concrete is much easier to remove than hardened material, which can reduce drum capacity and affect future mixing performance.
For example, a 100L mixer that develops significant concrete build-up over time may lose usable mixing space and place additional strain on the motor and drive components.
After use, remove leftover material, rinse the drum, clean discharge areas and check for any concrete deposits around mixing components.
For forced-action mixers such as the SoRoTo, cleaning the paddles and internal mixing parts is especially important because material can collect around moving components.
Motor and Moving Parts Maintenance
Regular inspection of mechanical and electrical components helps prevent unexpected breakdowns.
Important areas to check include:
- Drive belts
- Bearings
- Wheels
- Electrical connections
- Petrol engine components
- Safety guards
Electric mixers in this guide range from 550W to 1.1kW, while petrol models use Honda engines, meaning maintenance requirements differ between power types.
Electric mixers should have cables and connections inspected regularly, while petrol-powered models require checks for fuel systems, oil levels and air filters.
Preventing Concrete Build-Up
Preventing hardened concrete deposits is easier than removing them later. Regular cleaning after each use helps maintain mixing efficiency and prevents unnecessary stress on the motor and drive system.
This is particularly important for larger machines such as the 145kg Renegade RIUCM35, where hardened material can make cleaning and movement more difficult.
Operators should avoid leaving unused concrete inside the drum for extended periods and should never attempt to remove blockages while the mixer is running.
SafeWork NSW highlights that workers should not place hands or body parts inside mixers during cleaning, troubleshooting or maintenance while the machine is connected to power.
Seasonal Storage and Preparation
Proper storage helps protect the mixer from corrosion, weather exposure and mechanical issues when it is not used for extended periods.
Before storage:
- Clean all concrete residue
- Dry the mixer completely
- Store under cover
- Protect electrical components
- Prepare petrol engines correctly
Weight and portability should also be considered during storage planning. The mixers in this guide range from 88kg SoRoTo to 145kg Renegade, so suitable storage space and safe movement methods are important.
Before returning the mixer to operation, inspect the frame, wheels, controls, guards and power or engine components to ensure safe operation. A regular pre-start inspection can help identify problems before they affect productivity.
Conclusion
Choosing the right concrete mixer depends on matching the machine to the intended application rather than selecting the biggest capacity or highest power rating.
