Hubei Yichang Lime Powder Auto-Dosing Conveying Case

Case Overview

This case study focuses on a lime powder processing facility located in Yichang, Hubei Province. The client, a medium-sized industrial manufacturer, required a reliable and accurate dosing and conveying solution for their lime powder production line. headpowder was engaged to design and implement an automated system that addresses the specific challenges of handling fine, abrasive lime powder.

Client Challenges

The client faced several operational difficulties with their existing manual dosing process. Inconsistent feed rates led to variations in product quality, while manual handling caused significant dust emissions, posing health and safety risks to workers. Frequent equipment blockages and high maintenance costs further reduced overall efficiency. The lack of real‑time monitoring made it difficult to control inventory and optimize production scheduling.

Our Solution

headpowder developed a custom automated dosing and conveying system tailored for lime powder. The solution integrates a precision screw feeder with a sealed pneumatic conveying line, ensuring consistent material flow and minimal dust leakage. An advanced control unit with touch‑screen interface enables operators to set precise dosing parameters and monitor system status in real time. The closed‑loop feedback mechanism automatically adjusts feed rates to maintain target output, reducing waste and improving product uniformity. Additionally, the robust construction, including wear‑resistant liners and sealed joints, significantly extends equipment life and reduces maintenance intervals.

Key Outcomes

After installation, the client achieved a measurable improvement in dosing accuracy, with deviation reduced to under ±1%. Dust emissions decreased by more than 90%, creating a safer work environment. Unplanned downtime dropped by 70%, and overall production throughput increased by 25%. The system’s intuitive controls allowed existing staff to operate it with minimal training.
