Shandong Headpowder Engineering Co., Ltd. (headpowder) is a professional engineering company from Shandong, China. The company has successfully designed, manufactured, and commissioned a complete plastic powder automatic dosing and pneumatic conveying system in Cali, Colombia. This project is an important pneumatic conveying case in Latin America. It proves that a fully enclosed material transfer system can effectively handle plastic powders, provide accurate dosing, and create a clean and safe working environment.

The project was built for a plastics processing plant in Cali, one of Colombia’s most important industrial cities. The customer needed a reliable solution to transport plastic powder from storage to mixing and dosing equipment. Plastic powder can be dusty, hygroscopic, and difficult to move, especially under warm and humid conditions. Manual handling often causes dust pollution, material loss, and unstable batch quality. To solve these problems, the plant chose a modern automatic dosing and pneumatic conveying system to improve productivity and safety.

Headpowder’s engineering team designed a complete process line for this Latin America pneumatic conveying project. The main equipment includes a storage hopper, discharge device, rotary airlock feeder, positive displacement blower, conveying pipeline, cyclone separator, pulse-jet bag filter, weighing bin, and automatic control system. Every component was selected according to the characteristics of plastic powder, including particle size, bulk density, moisture content, and abrasiveness. The compact pipe layout is especially suitable for existing buildings with limited space.

In the automatic dosing pneumatic conveying process, plastic powder first enters the rotary airlock feeder from the storage hopper. A positive displacement blower generates steady air flow that carries the powder through the pipeline to the receiving point. At the delivery end, the cyclone separator separates most of the material from the air, while the bag filter cleans the remaining exhaust air. The powder then falls into the dosing unit, where load cells and an intelligent control system weigh each batch accurately. The PLC and HMI enable operators to set recipes, monitor production, and record data for full traceability.

For plastic powders with high bulk density or sensitive requirements, Headpowder can also apply dense-phase pneumatic conveying. This low-velocity, high-pressure method reduces pipe wear, material degradation, and energy consumption. In the Cali project, the automatic dosing function is closely integrated with the conveying sequence, so material feeding and weighing are perfectly synchronized. This guarantees high batch accuracy, reduces feeding errors, and makes production more consistent.

The benefits of this automatic dosing pneumatic conveying system are significant. It eliminates dust leakage, improves plant hygiene, and protects workers from exposure to fine powder. It also reduces labor costs because the process is fully automated and only needs simple supervision. Material losses are minimized, which lowers production costs. In addition, the sealed system prevents moisture absorption and contamination, preserving the quality of the plastic powder. For the Colombian customer, this means greater production stability and higher final product quality.

This project is not only a successful equipment supply but also a valuable reference for other manufacturers in Latin America. Colombia and other emerging markets need efficient and environmentally friendly material handling systems. Headpowder has proven that Chinese engineering can adapt to local conditions and provide responsive service. The company offers installation guidance, commissioning support, operator training, and spare parts supply to ensure long-term reliable operation.
