Complete case of leak-free sealed conveying of rubber additive powder in Xingtai, Hebei

In the field of rubber additive powder transportation, a certain company has long faced challenges such as dust leakage, material loss, and environmental pollution. To address this common pain point in the industry, Head Powder leveraged its mature pneumatic conveying technology to tailor a leak-free, sealed conveying system for them. This system has been successfully implemented on rubber additive production lines in Hebei, Xingtai, and other locations, achieving fully enclosed and low-pollution transfer from feeding to the final process.

Customer pain point analysis

Rubber additive powders have fine particle size and light specific gravity, making traditional mechanical or open pneumatic conveying prone to dust and leakage. On one hand, leakage leads to material waste and increases production costs; On the other hand, dust leakage seriously threatens operator health and makes it difficult to meet emission requirements set by environmental protection authorities. Additionally, powders are prone to moisture absorption and caking during transportation, affecting the stability of subsequent mixing processes. After trying various solutions, the company still faced issues such as low conveying efficiency, frequent system clogging, and high maintenance costs.

Detailed explanation of product solutions

To address these pain points, Head Powder offers a positive pressure dense phase pneumatic conveying solution, with the following main features:

• Fully sealed, leak-free design:The system uses highly sealed pipelines and rotary feeders, achieving full isolation from the feed inlet to the discharge point, with dust leakage rates below industry standards. Combined with the auto-artery flushing and back-blowing dust removal device, it helps keep the work environment clean.
• Moisture-proof and anti-caking treatment:Combined with nitrogen or dry air as the transport medium, the inner wall of the pipeline is specially polished to effectively prevent the adsorption and caking of rubber additive powders. The system is equipped with an online moisture monitoring module that can adjust conveying parameters in real time.
• Low energy consumption and efficient conveying:Uses optimized flow control technology for accurate gas-solid ratio, reducing compressed air consumption while improving conveying speed. Practical application data shows that unit energy consumption is about 35% lower than traditional dilute-phase conveying.
• Intelligent Control and Easy Maintenance:Integrates PLC and touchscreen HMI, supporting remote monitoring and fault self-diagnosis. Key components use a quick-install structure, allowing daily cleaning and replacement of wear parts to be completed in a short time, reducing downtime.

Application scenarios and results

This solution has already been put into use by multiple rubber additive enterprises in Hebei and Xingtai, covering various powder materials such as carbon black, zinc oxide, antioxidants, and accelerators. The system has operated continuously for over 8,000 hours without any leakage incidents. The material loss rate has dropped from the original 1.2% to within 0.1%, and the workshop's dust concentration meets the GBZ 2.1 occupational contact limit. The company successfully passed the environmental protection inspection.

Service support

Head Powder offers one-stop services from solution design, equipment manufacturing, installation and commissioning, to after-sales operation and maintenance. For the low-temperature northern winter environment, the system is equipped with heat tracing and insulation layers to help the equipment operate normally. At the same time, conveyor routes can be flexibly expanded according to customers' capacity upgrade needs.
