In the lime powder processing sequence of a company in Yibin, Sichuan, the original operation relied on manual operation, which was not only inefficient but also faced issues such as dust dispersion and large fluctuations in dosing amounts. By introducing the lime powder automated dosing system provided by Head Powder, the company achieved full-process automation transformation from material storage, conveying, and metering to dosing, improving production line stability and working environment quality.

Customer pain points

Before the renovation, the client mainly faced the following challenges: First, when manually adding lime powder, dust was severely dispersed, causing ongoing impacts on operator health and the surrounding environment; Second, large errors in manual measurement lead to fluctuating lime powder dosing amounts, affecting the stability of subsequent processes; Third, under traditional operating modes, dosing efficiency is limited by factors such as personnel fatigue and shift handovers, making it difficult to meet the demands of continuous production; Fourth, there is a lack of real-time data feedback, so maintenance personnel cannot promptly grasp equipment operating status, resulting in prolonged troubleshooting time.

Product advantages

To address these pain points, Head Powder has launched an automated lime powder dosing system that offers a one-stop solution:

• Fully sealed negative pressure conveying and automatic unpacking and dosing, controlling dust spillage from the source and improving on-site air quality;
• Uses a high-precision weighing module and closed-loop control algorithm, with dosing accuracy deviation controlled within ±1%, meeting process requirements; li>
• The system supports automatic switching between multiple time periods and multiple ratios, allowing flexible adjustment of dosing volume according to production line needs, and supporting stable continuous operation;
• Equipped with data collection and remote monitoring functions, it displays material level, flow, alarms, and other information in real time, facilitating rapid response for operation and maintenance personnel.

After the system was put into operation, the dust concentration at the customer's lime powder processing site dropped significantly, operator labor intensity decreased, the dosing pass rate increased to over 99%, and overall production efficiency increased by about 30%.

System composition and workflow

The system mainly consists of a storage silo, negative pressure conveying pipeline, automatic unpacking machine, weighing hopper, screw feeder, and intelligent control cabinet. Lime powder is pneumatically conveyed by a tank truck into the storage bin, then broken by an automatic unpacking machine, then delivered via negative pressure pipeline to the weighing hopper. Feeding speed is controlled by feedback signals from the weighing sensor, and the final feed is accurately fed into the mixing and mixing equipment. The entire process is uniformly scheduled by a PLC controller, supporting both local and remote operation modes.
