In the powder transportation segment of the rubber and plastics industry, the safety risks posed by flammable and explosive dust have always been a core concern for enterprises. A rubber and plastic manufacturer located in Kunming, Yunnan, has a production process involving the transfer and feeding of large quantities of rubber and plastic powder. The original conveying equipment had hidden dangers such as dust leakage, static electricity buildup, and insufficient explosion-proof ratings, which not only affected the workshop environment but also posed threats to the safety of operators and equipment. To address these pain points, Head Powder has customized an explosion-proof sealed conveying system for rubber and plastic powder, achieving sealed and safe operation throughout the entire process from feeding to the end of the process.

Analysis of customer pain points

This customer faced multiple challenges in powder transportation: first, dust emissions caused raw material waste and workshop pollution, resulting in high cleaning and maintenance costs; Second, ordinary conveying equipment lacks effective explosion-proof measures, which may trigger ignition or explosion accidents if encountered by sparks or static electricity; Third, powder materials tend to clump and bridge easily, causing poor feeding and affecting production continuity; Fourth, traditional open conveying methods cannot meet increasingly stringent environmental protection and safety production regulatory requirements. Customers urgently need a sealed conveying solution that supports both safety and efficiency.

Solutions and product advantages

After in-depth on-site research, the Head powder technology team designed and implemented a fully sealed explosion-proof conveying system tailored to the characteristics of rubber and plastic powders. The system uses high-grade explosion-proof motors, anti-static pipelines, and explosion-proof electrical control cabinets to eliminate ignition sources at the source; Flange seals and quick-release clamps are used at pipeline connections, helping to eliminate leakage; Equipped with a combined arch-breaking device and pneumatic conveying process to improve powder bridging issues; At the same time, an intelligent monitoring system is integrated to detect pipeline pressure, temperature, and dust concentration in real time, and automatically shuts down and alarms in case of abnormalities. After the complete system was put into operation, dust concentration in the customer's workshop dropped by over 80%, energy consumption was cut by about 15%, and it successfully passed local safety and environmental protection inspections.

Application value

This project not only solved the customer's flammation and explosion risks and environmental challenges but also improved raw material utilization and production continuity. Sealed conveying reduces material loss and manual cleaning frequency; Explosion-proof design supports continuous operation of personnel and equipment; Intelligent control reduces operational difficulty and human error. This case fully demonstrates Head Powder's technological accumulation and customization capabilities in explosion-proof sealed transportation, and also provides a replicable reference path for safety upgrades in similar rubber and plastics enterprises.
