High‑Accuracy Customized Screw Auger Conveyor Industrial Application Case

A domestic new‑energy material enterprise faced material‑transport bottlenecks in its lithium carbonate production workshop. The existing conveying equipment caused material segregation, blockage and large dust leakage. Material feeding accuracy could not meet process requirements, bringing unstable product quality and high‑frequency equipment maintenance. The enterprise adopted high‑accuracy customized screw auger conveyor to solve the above‑mentioned production pain points.

Core Customization Points

1. Structure customization: According to site layout, the inclined‑type screw auger feeding structure was adopted. Special anti‑clogging screw blades were designed for easy‑caking lithium‑carbonate powder. The whole machine adopted 316L stainless steel to satisfy anti‑corrosion requirement for battery‑grade materials.

2. Precision feeding configuration: Equipped with variable‑frequency drive and real‑time flow monitoring module, to realize continuous and stable quantitative feeding.

3. Sealing improvement: Adopted multi‑stage sealing structure to effectively control dust overflow in closed production environment.

Operation Effect

1. Feeding precision: Material feeding error is controlled within ±1.5%, solving the problem of uneven material ratio and stabilizing downstream reaction process.

2. Stable operation: Material blockage failure rate dropped by 92%; weekly maintenance workload was greatly reduced. Continuous running time reaches 720 hours without halt.

3. Environment & benefit: Dust leakage is basically eliminated. Labor cost for on‑site cleaning and post‑processing loss decreased. Annual comprehensive production cost saved more than 280,000 RMB.

Project Summary

This customized screw auger conveyor matches the special properties of new‑energy powder materials. It not only meets the site space and anti‑corrosion demands, but also realizes high‑precision quantitative feeding. The case proves that tailor‑made auger conveying equipment can effectively solve complex material‑handling challenges in fine‑chemical and new‑energy industries.
