Consistent slurry composition in the preparation and storage phase guarantees stable casting outcomes, higher material utilization and reliable production performance.
Proper agitation inhibits solid settlement via continuous gentle circulation, enabling uniform distribution of cement, lime, fly ash and aluminium powder.
AAC Slurry Separation Control Factors
Several operational conditions affect the segregation of AAC slurry. To achieve stable storage, raw material features, slurry viscosity, tank structure and stirring parameters must be well matched.
| Control Factor | Influence on Slurry Stability |
| Particle distribution | Determines sedimentation speed and material uniformity |
| Slurry viscosity | Affects suspension ability during storage |
| Agitation speed | Controls mixing efficiency and prevents excessive turbulence |
| Storage time | Longer waiting periods require stable continuous agitation |
| Agitator design | Determines circulation pattern and bottom material movement |
AAC slurry contains particles with different densities. Proper agitation prevents settlement, maintains uniform composition, and ensures stable casting performance.
Approach1: Maintain Continuous Slurry Movement
Maintaining stable internal circulation in storage tanks prevents AAC slurry separation by reducing particle settlement and improving material consistency.
Excessive agitation may increase air content and energy consumption. Balanced mixing ensures sufficient circulation while protecting slurry properties.
A well-designed slurry agitator creates vertical and horizontal flow patterns, lifting settled materials and maintaining uniform slurry distribution.
Key requirements include:
- Uniform slurry circulation throughout the tank
- Reduced dead zones at the bottom area
- Stable low-speed mixing operation
- Continuous suspension of solid particles
- Suitable mixing intensity for AAC materials
Approach2: Select Suitable AAC Slurry Agitator Structure
The agitator configuration dictates slurry flow patterns. Optimized mechanical designs are necessary to accommodate varying tank dimensions and slurry properties.
AAC slurry agitators consist of motors, transmission assemblies, shafts and impellers, generating circulating force to keep solid particles suspended.
| Component | Function |
| Motor system | Provides stable power output for continuous mixing |
| Shaft assembly | Transfers rotational force into the slurry |
| Mixing blades | Creates circulation and particle suspension |
| Support structure | Maintains stable operation under long-term working conditions |
Approach3: Control Agitation Speed
Low-speed agitation maintains AAC slurry suspension, prevents sedimentation, and avoids excessive disturbance during storage operations.
The suitable speed depends on:
- Slurry density
- Storage tank diameter
- Material particle size
- Production waiting time
- Required casting consistency
| Operating Condition | Recommended Control Direction |
| Short storage period | Stable intermittent or continuous mixing |
| Long storage period | Continuous low-speed agitation |
| High solid content slurry | Higher torque mixing structure |
| Large storage tank | Optimized circulation blade design |
Approach4: Optimize Storage Tank and Agitator Matching
Unstable agitation causes slurry inconsistency, affecting block density, strength distribution, and production efficiency. Speed control requires proper equipment matching.
The matching design should consider:
- Tank capacity
- Slurry filling height
- Agitator installation position
- Blade diameter
- Mixing coverage area
For example, a deeper storage tank usually requires a longer shaft and optimized blade arrangement to ensure bottom circulation. A wider tank may require a larger mixing range to avoid stagnant areas.
Approach5: Prevent Sediment Accumulation at Tank Bottom
The tank bottom is the most sensitive area for slurry separation because heavier particles naturally move downward under gravity.
Once sediment accumulates, normal mixing may require more power to redisperse the material. Continuous bottom circulation is therefore important during storage.
Effective design methods include:
- Proper blade position near bottom area
- Strong vertical circulation capability
- Suitable shaft length
- Stable torque output
- Smooth material flow transition
High-performance agitators avoid merely churning the surface layer of slurry. They build an integrated top-to-bottom circulation channel to sustain homogeneous material dispersion.
Approach6: Maintain Slurry Temperature and Storage Environment
Temperature changes can also influence slurry behavior during storage. Stable storage conditions help maintain predictable slurry characteristics.
Important factors include:
| Environmental Factor | Control Requirement |
| Temperature variation | Avoid excessive fluctuations |
| Storage duration | Minimize unnecessary waiting time |
| Tank protection | Reduce external environmental influence |
| Equipment operation | Maintain stable working conditions |
Agitators are primary devices for inhibiting material separation, yet ambient storage conditions have impacts on slurry stability.
The integrated AAC slurry storage system requires well-matched tank structures, effective agitators and orderly production arrangements.
Approach7: Optimize Slurry Agitator Running Mode
Continuous operation mode should be selected according to slurry storage requirements, production rhythm, and material characteristics. The objective is maintaining slurry suspension while avoiding unnecessary mechanical stress.
Key considerations include:
- Continuous operation during long waiting periods
- Intermittent mixing for short storage cycles
- Stable torque output under different slurry conditions
- Automatic control based on production requirements
A properly configured running mode helps maintain consistent slurry properties between preparation and casting stages.
Slurry Agitator Maintenance for Long-Term Stability
Regular maintenance ensures that slurry agitators maintain stable performance throughout continuous production cycles.
Wear, vibration, or reduced rotation efficiency may affect slurry circulation quality over time.
Maintenance focus includes:
- Checking motor operating conditions
- Inspecting shaft alignment
- Evaluating blade wear
- Confirming transmission stability
- Cleaning material accumulation areas
