Organic pigments are widely used in plastics, inks, coatings, and rubber. Their fine particles and low bulk density make them challenging to handle. Pneumatic conveying offers a safe, efficient, and dust-free solution for transporting these sensitive materials. These systems prevent material segregation and reduce manual handling.

We provide customized organic pigment pneumatic conveying systems designed for each plant's unique requirements. Our solutions cover various conveying distances, throughputs, and material properties. We also ensure minimal product degradation and easy cleaning. We provide complete process control and automation to ensure consistent transfer. Our engineering team evaluates every aspect of the conveying process to ensure optimal performance.

A typical system includes a feed hopper, rotary valve, blower or vacuum pump, pipeline, cyclone, filter, and control system. Depending on pigment characteristics, we select either dilute phase or dense phase conveying. Each component is selected based on the pigment's particle size, abrasiveness, and hygroscopicity.

Dilute phase uses high velocity and low pressure, suitable for non-fragile pigments. Dense phase operates at low velocity and high pressure, which is ideal for fragile pigments that may break during transport. Selection depends on the particle strength and air velocity to prevent breakage.

Pipeline design is essential for organic pigments. We use smooth pipes, long-radius bends, and proper air velocity to prevent blockages and particle damage. The system also includes automatic purging for quick product changeovers. The purge system uses compressed air or nitrogen to clean the line after each batch. This reduces downtime and ensures product quality for the next batch.

Dust control and safety are critical. Our closed-loop systems utilize negative pressure, high-efficiency filters, and explosion-proof equipment. For flammable pigments, inert gas conveying can be provided to meet international safety standards. Our solutions meet ATEX and NFPA guidelines for combustible dust.

As an experienced organic pigment conveying manufacturer, we offer full engineering, fabrication, installation, and commissioning. Our in-house production ensures high quality and short lead times. We also provide remote support and spare parts. Our engineers also offer operator training and performance optimization. Our team works closely with the client to ensure smooth installation and startup.

Material characteristics, such as particle size, moisture, and flowability, are analyzed in our laboratory. This data allows us to accurately size the system and avoid common problems like line blockage and poor feeding. We also measure bulk density and angle of repose to ensure reliable flow.

We supply a full range of components, including screw feeders, rotary airlocks, slide gates, and silos. Stainless steel options are available for food-grade or pharmaceutical-grade pigments, while carbon steel with wear-resistant liners serves industrial uses. For abrasive pigments, ceramic-lined bends are available to extend service life.

Our reliable and cost-effective organic pigment conveying solutions have been delivered to pigment producers and factories worldwide. Contact us for a tailored proposal that meets your production needs. Our solutions are suitable for both new plants and system retrofits. We have references in many countries and can provide case studies on request.
