A self-loading concrete mixer combines material loading, mixing, and transportation into a single machine, streamlining concrete production on-site. The operational process involves three key stages: pre-operation checks, the main mixing process (including loading, water addition, and mixing), and post-operation procedures. The machine's hydraulic systems and operator cabin controls allow efficient material handling from loading aggregates to discharging the final mix. Its integrated design eliminates the need for separate loaders and mixers, making it ideal for remote or small-scale construction projects.
Key Points Explained:
-
Pre-Operation Preparation
- Position the self loading concrete mixer on stable ground near material piles
- Conduct safety checks (fluid levels, tire pressure, hydraulic systems)
- Verify all control systems in the operator cabin are functional
-
Material Loading Process
- Use the integrated loader bucket or hydraulic arm to scoop aggregates (sand, gravel)
- Transfer materials to the hopper, with options including:
- Hydraulic hopper systems
- Conveyor belt mechanisms
- Built-in weighing system ensures precise material proportions
- Cement is added separately through a dedicated loading port
-
Water Addition & Mixing
- Activate the water dosing system (typically 10-15% of total mix volume)
- Water pump delivers measured quantity based on mix design
- Rotating drum initiates mixing (usually 3-5 minutes per batch)
- Drum rotation speed varies by phase:
- 12-18 RPM during mixing
- 2-6 RPM during transport
-
Transportation & Discharge
- Mixed concrete is transported while drum continues slow rotation
- Adjustable discharge chute (180-270° rotation) directs concrete flow
- Hydraulic systems control chute height (typically 2-4m reach)
- Discharge rate averages 0.5-1.5 m³/minute depending on mix viscosity
-
Operator Controls
- Centralized cabin controls manage:
- Engine throttle (usually 1500-2000 RPM operating range)
- Hydraulic pressure (140-200 bar typical range)
- Drum rotation direction (clockwise for mixing, counterclockwise for discharge)
- Digital displays show critical parameters:
- Batch volume (common capacities: 4-12 m³)
- Mixing time
- System diagnostics
- Centralized cabin controls manage:
-
Post-Operation Procedures
- Immediate drum cleaning with water jets (prevents concrete buildup)
- Hydraulic system depressurization
- Inspection of wear parts (blades, hopper mechanism)
- Documentation of batch quantities for project records
Have you considered how the integrated design reduces labor requirements compared to traditional mixer+loader setups? These machines exemplify the trend toward multifunctional construction equipment that improves efficiency on smaller job sites.
Summary Table:
| Stage | Key Actions | Equipment Features |
|---|---|---|
| Pre-Operation | Position machine, check fluids/tires, test controls | Hydraulic system verification, operator cabin diagnostics |
| Material Loading | Scoop aggregates, transfer to hopper, add cement | Integrated loader bucket, weighing system, dedicated cement port |
| Mixing | Add water (10-15% volume), rotate drum (3-5 mins) | Adjustable RPM (12-18 for mixing), water dosing system |
| Transport/Discharge | Rotate drum slowly, position chute (2-4m reach) | 180-270° chute rotation, 0.5-1.5 m³/minute discharge rate |
| Post-Operation | Clean drum, depressurize hydraulics, inspect wear parts | Water jets for cleaning, diagnostic documentation tools |
