The chain bucket elevator is a professional vertical bulk material lifting equipment specially optimized for dry mortar production lines. As the core conveying equipment in mortar production processes, it is mainly used for continuous vertical lifting of powdery and granular materials such as dried sand, cement, fly ash, slag powder and mortar additives. Adopting reliable chain traction and bucket loading structure, the equipment realizes stable, sealed and high-efficiency vertical transportation of materials from low-level feeding points to high-level mixing bins, storage silos and screening equipment. It perfectly solves the problems of low efficiency, serious dust leakage and unstable feeding of traditional conveying equipment. With adaptive design for abrasive and dry building materials, it can support 24-hour continuous heavy-duty operation of full-automatic dry mortar production lines, ensuring uniform and stable material supply for each production link, and effectively improving the overall automation and production efficiency of mortar processing.

- Stable Chain Traction & High Reliability: Adopts high-strength alloy traction chain and thickened integrated buckets, featuring strong tensile resistance, excellent wear resistance and anti-fatigue performance. Different from belt-type elevators, the chain transmission structure avoids slipping and deviation caused by material weight and long-term operation, ensuring stable conveying speed and zero material throwing during operation, with extremely low failure rate.
- Full Sealed Structure & Zero Dust Leakage: The whole machine adopts fully enclosed welded shell with reinforced sealing design at feeding and discharging ports. It completely suppresses dust overflow during material lifting and conveying, effectively improving the workshop production environment. It fully meets the environmental protection production standards of dry mortar factories and solves the dust pollution problem of traditional conveying equipment.
- Large Conveying Capacity & High Efficiency: Optimized bucket arrangement and material lifting trajectory design realize continuous and efficient material loading and unloading. The conveying capacity covers multiple specifications to adapt to small, medium and large mortar production lines. The stable lifting speed ensures uniform material supply, effectively matching the continuous operation rhythm of mortar mixing and batching systems.
- Strong Material Adaptability & Wear Resistance: Specially designed for abrasive dry building materials such as quartz sand and machine-made sand. The contact parts of buckets and chains are treated with high-temperature wear resistance and anti-corrosion process, which can adapt to long-term conveying of high-abrasive, dry and non-sticky powdery and granular materials, with long service life.
- Compact Structure & Flexible Installation: Vertical integrated layout occupies small floor space, saving workshop area and civil construction cost. The equipment height and conveying specifications can be customized according to on-site workshop layout and process height difference. It supports flexible docking with mixing bins, silos, screening machines and other equipment, with strong site adaptability.
- Low Operation Cost & Easy Maintenance: The equipment has a simple and reasonable mechanical structure with few vulnerable parts. The chain and bucket components are standardized and replaceable, with low daily maintenance difficulty. Low power consumption and high operation efficiency effectively reduce long-term production and operation costs for enterprises.
- Safe & Intelligent Operation: Equipped with anti-breakage, anti-blocking and overload protection devices. It supports linkage operation with the whole mortar production line, with automatic stop and alarm functions in case of material blockage, overload and chain failure. The matching intelligent control system realizes unattended automatic conveying operation.

- Perform a full pre-start inspection daily, focusing on the tightness and wear of the traction chain, firmness of bucket bolts, sealing of the shell, and flexibility of transmission parts. Eliminate loose parts, foreign blockages and severe wear faults before startup.
- Follow the standard startup sequence: start the elevator for no-load operation first, confirm stable chain operation and no abnormal noise, then start feeding. Strictly prohibit load startup to avoid chain overload, bucket deformation and motor burnout.
- Keep uniform and stable feeding volume, avoid sudden excessive feeding causing internal material blockage, chain jamming and material overflow. It is forbidden to feed oversized hard sundries to prevent bucket damage and equipment failure.
- Regularly check the chain tension during operation, adjust the tensioning device in time to prevent chain loosening, deviation or falling off, and ensure synchronous and stable operation of the chain and buckets.
- Prohibit long-term overload operation of the equipment. Match the feeding volume according to the rated conveying capacity to avoid accelerated wear of chain and bucket components and shortened service life caused by long-term overload.
- Regularly clean residual materials and dust inside the machine shell, feeding and discharging ports to prevent material accumulation from affecting conveying efficiency and causing blockage faults during subsequent operation.
- Regularly lubricate transmission bearings, sprockets and chain components, check the wear degree of buckets, chains and sealing parts, and replace severely worn and aging parts in time.
- Cut off the total power supply completely during equipment maintenance, debugging and cleaning. It is forbidden to open the sealed shell or touch running parts during operation to prevent mechanical injury safety accidents.
- Keep the operating environment dry and ventilated, regularly inspect electrical circuits, sensors and linkage control systems to ensure sensitive signal response and stable linkage with the mortar production line.
- Stop feeding first when shutting down the equipment, and continue no-load operation for 3-5 minutes to completely discharge internal materials, then cut off the power supply to avoid material accumulation inside the machine.
