In AAC production, sand, quicklime, and fine powder require different conveying solutions due to their unique material properties and handling challenges.
Custom Belt Conveyor systems optimize structure, capacity, and protection design to ensure stable material transfer throughout AAC production processes.
Material Characteristics Determine Belt Conveyor Design
Conveyors designed without taking material properties into account often suffer from uneven feeding, heavy dust generation, severe belt abrasion and material buildup. Hence, material analysis must be completed prior to selecting or customizing belt conveyor systems.
| Material | Main Characteristics | Conveyor Design Focus |
| Sand | Heavy, abrasive, granular material | Wear resistance and stable transportation |
| Quicklime | Reactive powder, easy to absorb moisture | Sealing and dust control |
| Fine Powder | Lightweight, easy to disperse | Closed conveying and accurate feeding |
Sand Handling

Stable Conveying
As a primary AAC raw material, sand needs crushing, grinding and stockpiling before slurry preparation. Continuous contact with conveyor belts during transport leads to sustained belt wear.
The main customization considerations include:
- High wear-resistant conveyor belt selection
- Reinforced conveyor frame structure
- Suitable belt width according to production capacity
- Stable tension control for long-distance conveying
High Wear Resistance
Sand particles create continuous friction during transportation. The conveyor belt and supporting rollers should be selected according to abrasion levels to extend service life.
For heavy sand conveying applications, thicker belts and stronger roller systems can provide better durability under continuous operation.
Large Conveying Capacity
AAC plants usually require continuous sand supply. Belt width and speed should match production requirements to prevent material shortage during processing.
Typical customization factors include:
- Belt width selection
- Conveyor length
- Inclination angle
- Motor power configuration
Flexible Layout Adaptation
Workshop layouts vary widely. Custom belt conveyors adopt horizontal, inclined or composite conveying structures to link various processing devices. Such flexible design is critical for renovated AAC production lines constrained by limited installation space.
Quicklime Handling

Moisture Protection and Safe Material Transfer
Quicklime acts as a core binder for AAC block manufacturing, yet its conveying standards differ from sand.
Highly susceptible to moisture reactions, quicklime deteriorates if exposed to humid surroundings. Conveyor systems for this material thus require enhanced sealing and protective structures.
Closed Conveying Structure
During transportation, quicklime powder can generate dust. A covered or enclosed conveyor structure helps reduce dust dispersion and protects the workshop environment.
- Covered belt conveyor
- Sealed transfer points
- Dust collection connection points
Moisture Prevention Design
Quicklime properties are highly susceptible to storage and transport conditions. Conveyor parts shall limit contact with outside humidity.
Customization options include:
- Protective covers
- Sealed feeding sections
- Weather-resistant components for outdoor installation
Controlled Feeding Accuracy
Unlike large sand particles, quicklime requires more accurate material feeding because its proportion affects the AAC mixture ratio.
A customized conveyor system can work together with feeding equipment to maintain stable material supply and improve mixing consistency.
Fine Powder Handling

Precision Conveying
Lightweight, diffusible and airflow-sensitive fine powders demand special conveying solutions.
Such fine materials are generated during grinding and raw material preparation in AAC manufacturing, where standard open conveying structures often deliver unsatisfactory performance.
Dust-Controlled Transportation
Fine particles can easily escape during loading and unloading. Recommended solutions include:
- Enclosed conveyor sections
- Sealed discharge points
- Optimized feeding devices
Smooth Material Flow
Though lightweight, fine powders disperse readily. Shock loads or irregular feeding can result in uneven material spreading.
A suitable conveyor design focuses on:
- Stable belt running speed
- Uniform feeding
- Reduced material accumulation
Integration with Automated Production Lines
Automated material transport is now a standard need for new AAC production facilities. Sensors and control systems fitted on fine powder conveyors sustain steady operation.
Tailored conveyor setups create more efficient links among storage, weighing and mixing devices.
Comparison of Three Custom Belt Conveyor Solutions
| Item | Sand Conveyor | Quicklime Conveyor | Fine Powder Conveyor |
| Main Challenge | Abrasion and heavy load | Moisture and dust | Dispersion and accurate feeding |
| Key Design | Reinforced structure | Sealed protection | Dust-controlled conveying |
| Priority | Durability | Material protection | Conveying precision |
| Suitable Area | Crushing and storage sections | Raw material preparation | Grinding and feeding sections |
Customization Factors for AAC Belt Conveyor Systems
Conveyor Capacity
Output volume dictates conveyor belt dimensions, speed and motor power. Large AAC plants face full-process shutdown risks if conveying throughput fails to match production demands.
Customization should consider:
- Material feeding volume
- Operating hours
- Production output
- Future expansion requirements
Conveying Distance and Layout
AAC factories often have complex production layouts. The conveyor length and installation angle must match the actual site conditions.
- Horizontal transportation
- Inclined transportation
- Long-distance conveying
- Multi-section conveying systems
Material Protection Requirements
Sand focuses on wear protection, quicklime focuses on moisture isolation, and fine powder focuses on dust control.
Therefore, conveyor customization should balance:
- Material characteristics
- Production environment
- Maintenance requirements
- Operating stability
Drive System Selection
For continuous AAC production, stable motors and appropriate transmission systems help maintain consistent operation during long working periods.
Key considerations:
- Motor power
- Speed control
- Load conditions
- Operating frequency
