PC particles, also known as polycarbonate pellets, are high-performance engineering plastics widely used in automotive, electronics, optical media, and consumer goods. In modern manufacturing, the transfer of PC particles from storage silos, bags, or drying hoppers to processing machines must be reliable, clean, and efficient. Pneumatic conveying solutions for PC particles provide a closed, automated, and flexible system that moves bulk materials through pipelines using air pressure or vacuum. These systems eliminate manual handling, reduce contamination risks, and improve overall production safety.

A complete PC particle pneumatic conveying system usually consists of a feed device, a conveying pipe, a separation device, a gas source, and an electrical control system. The feed device introduces granules into the pipeline at a controlled rate. The gas source, which may be a roots blower, compressor, or vacuum pump, provides the carrying velocity. At the downstream end, a cyclone separator or filter receiver separates the particles from the air stream. PLC-based controls monitor pressure, speed, and level to ensure continuous and stable operation.

Two common conveying modes are available for PC particles: dilute phase and dense phase. Dilute phase conveying uses high air velocity and low pressure to suspend particles in the air stream. It is suitable for short conveying distances and moderate capacities. Dense phase conveying operates at low velocity and high pressure, pushing slugs of material along the pipeline. This method is gentler and reduces particle breakage and dust generation. For PC particles, which are relatively hard but can be scratched or scuffed, dense phase is often preferred when higher quality is required.

The advantages of a customized PC particle pneumatic conveying solution are significant. Because the system is fully enclosed, it prevents dust leakage and keeps the material free from moisture and external impurities. It also saves floor space by running pipes overhead or along walls. The automation level is high, which reduces labor costs and enables accurate batch control. Furthermore, pneumatic conveying allows flexible routing around existing equipment, making it ideal for retrofitting or expanding production lines.

When designing a PC particle conveying system, several important parameters must be considered. These include conveying distance, vertical lift, throughput rate, bulk density, particle size distribution, shape, and moisture content. The number and radius of bends affect pressure drop and material degradation. The pipeline diameter and air velocity must be matched to the material properties to avoid blockage or wear. Proper sizing of the blower or vacuum pump is critical to achieve the required conveying velocity while minimizing energy consumption.

Our company specializes in custom PC particle pneumatic conveying solutions. We start with a detailed analysis of your material and site conditions. Then we design the optimal system layout, select the most suitable components, and provide installation and commissioning services. Our team has extensive experience in handling polycarbonate and other plastic pellets in various industries. We can integrate the conveying system with drying hoppers, gravimetric blenders, injection molding machines, and extruders to create a seamless production line.

Typical applications include PC particle feeding to injection molding machines for automotive light covers, electronic casings, and safety equipment. They are also used in extrusion lines for PC sheets, films, and profiles. In addition, PC/ABS alloy pellets can be conveyed safely with the same system when the parameters are adjusted accordingly. From small workshops to large-scale manufacturing plants, our conveying systems are designed to meet strict production demands.

We also offer auxiliary equipment such as hopper loaders, vacuum receivers, rotary valves, filter receivers, and control panels. All components are selected for durability, easy maintenance, and compatibility with PC particles. Optional features include variable frequency drives, anti-wear bends, and explosion-proof electrical equipment when required. With proper design and regular maintenance, our pneumatic conveying systems provide years of dependable operation, lower downtime, and a higher return on investment.
