To address common issues in powder storage and transportation in the rubber and plastics industry, such as bin arching and poor discharge, Head Powder customized a bin arch breaking conveying system for a rubber and plastics company in Shiyan, Hubei, effectively supporting the continuous normal operation of the production line.

Customer pain points

The company mainly uses rubber and plastic powder, with large silo volumes. During long-term storage, moisture, static electricity, and friction between particles easily cause arching and bridging on silo walls and discharge ports, leading to interruptions in feeding or flow fluctuations. Traditional manual tapping or vibration methods have limited effectiveness and cannot achieve automated control, severely restricting production efficiency and increasing maintenance costs.

Solutions and product advantages

Based on on-site conditions, Head Powder has designed an integrated arch-breaking conveying system. This system reasonably arranges a pneumatic arch-breaking device at the silo cone, intermittently spraying high-pressure gas to instantly loosen and decompose the arched material; At the same time, by working with more precise conveying fans and sealed pipelines, the powder after the arch is continuously and stably transported to the next process. The entire system uses PLC automatic control, allowing real-time adjustment of arch breaking frequency and intensity based on material level signals and conveying pressure, enabling unattended operation. Compared to the original solution, this system improves feed uniformity, reduces feeding interruption time by over 90%, and decreases the need for manual intervention, saving operating costs for the company.

Application Effects

After the project was put into operation, the conveying efficiency of rubber and plastic powder was stably supported, malignant arching no longer occurred in the silos, backend equipment operated smoothly, and product quality consistency improved significantly. This arch-breaking conveyor system has been successfully replicated on multiple similar production lines, validating its reliability and applicability.
