Antistatic agent powders are vital additives used to prevent electrostatic discharge and reduce surface resistance in plastics, films, fibers, and electronics. Due to their fine particle size, low bulk density, and high cohesion, they are difficult to handle with ordinary mechanical equipment. Dust leakage, material degradation, and unstable feeding are common problems. A purpose-designed pneumatic conveying system offers a sealed and automated way to transfer these powders from storage to processing points, preserving product quality and providing a clean, safe working environment.

The core system consists of a receiving hopper, a precisely controlled feeding device such as a rotary valve or screw feeder, a conveying pipeline, a cyclone or bag filter separator, and a programmable logic controller. The antistatic powder is metered into the pipe and transported by low-pressure or high-pressure air. Pressure sensors and level indicators send real-time data to the PLC, which adjusts the feed rate and air velocity to maintain stable flow. All components are built with smooth surfaces and easy-clean designs to prevent residue build-up and to allow rapid product changeovers.

For most antistatic agent powders, dense-phase conveying is the preferred choice. In this mode, the material moves through the pipeline as slow-moving plugs, which minimizes particle attrition, reduces dust generation, and protects the powder's performance. Dilute-phase conveying may be selected for short distances or free-flowing materials. Our engineers test each powder's particle size, moisture content, cohesion, and explosion limits before deciding on the best system configuration. This careful analysis ensures reliable operation, lower energy consumption, and minimal wear on the pipeline.

Safety is a major concern when handling antistatic powders, so our systems feature completely sealed pipelines, explosion-proof electrical components, and full antistatic grounding. The conveying pipe is manufactured from stainless steel with an optional mirror-polished interior to reduce friction and material accumulation. All hoppers and filters are bonded to earth to prevent static charge build-up. An automatic purge system cleans the line after each batch, preventing cross-contamination and maintaining consistent quality. The entire process is enclosed, eliminating dust emissions and improving workplace air quality.

Every production line is unique, and we offer fully customized antistatic powder conveying solutions. Our team begins with a detailed material analysis and an on-site inspection to determine the optimum conveying capacity, pipe diameter, bend radius, and feeding accuracy. Custom options include nitrogen inerting for explosion protection, remote monitoring and control, and special surface finishes for food-grade or pharmaceutical applications. Equipment can be fabricated to meet ATEX, CE, or GMP requirements. We also provide complete documentation, installation supervision, and operator training to ensure a smooth startup and long-term reliability.

These pneumatic conveying systems are widely used in chemical plants, masterbatch production, plastic compounding, cable materials, and additive manufacturing. Antistatic powders are often dosed in small quantities, so precise and repeatable feeding is critical. Our systems deliver consistent batches to mixers, extruders, and packaging machines, improving product uniformity and reducing waste. By replacing manual handling, they also lower labor costs and enhance operator safety. With proven technology and responsive after-sales support, our antistatic powder conveying solutions help manufacturers achieve higher efficiency, safer operations, and a better return on investment.
