Caprolactam is a hygroscopic and cohesive material commonly used in nylon production. During pneumatic conveying, its tendency to absorb moisture and form lumps often leads to pipeline blockages, equipment wear, and production downtime. These challenges require a carefully engineered approach to maintain material integrity and system reliability. Headpowder addresses these pain points with customized pneumatic conveying solutions designed specifically for caprolactam handling.

Material Characteristics

Caprolactam exhibits a low melting point (around 69°C) and strong hygroscopicity. When exposed to humidity, it absorbs moisture quickly, causing surface stickiness and agglomeration. The material is also abrasive in its solid form, which can accelerate wear on conventional conveying equipment. These properties demand a system that minimizes exposure to ambient air, controls temperature, and reduces mechanical impact.

Product Overview

The Headpowder caprolactam pneumatic conveying system is a fully integrated equipment set that includes a dosing feeder, conveying pipeline, air source unit, dust collector, and control panel. The system adopts dense-phase or dilute-phase conveying modes based on material characteristics and customer requirements. All components are fabricated from stainless steel or specialized alloys to resist corrosion and abrasion.

Solution Advantages

Moisture Prevention Design

The conveying circuit is sealed with airtight flanges and uses dehumidified compressed air to prevent moisture ingress. The entire pipeline is insulated to maintain stable temperature, reducing the risk of condensation and lump formation.

Wear-Resistant Construction

Pipe bends are lined with ceramic or treated with hardened steel to withstand the abrasive nature of caprolactam particles. Straight sections are made from thick-wall seamless tubing, extending service life and reducing maintenance frequency.

Precision Flow Control

An intelligent dosing system regulates material feed rate based on pressure and density feedback. This ensures consistent conveying velocity, minimizes particle degradation, and prevents pipeline blockages even during start-up or shutdown phases.

Automated Operation & Monitoring

The control system includes PLC-based automation with touch screen HMI. Operators can set parameters, monitor real-time pressure and flow, and receive alerts for abnormal conditions. Remote monitoring and data logging support predictive maintenance and process optimization.
