Shandong Headpowder Engineering Co., Ltd. (abbreviated as headpowder) successfully delivered a comprehensive positive pressure pneumatic conveying system for resin powder materials in Palembang, Indonesia. This project serves as a benchmark case for pneumatic conveying solutions in Southeast Asia, showcasing the company's expertise in handling fine, cohesive, and abrasive resin powders under demanding industrial conditions. The Palembang facility required a reliable, dust-free, and high-capacity transfer method to move resin powder from storage to processing stations, and headpowder's engineered system met all operational requirements.
The client, a leading chemical manufacturer based in Palembang, Indonesia, faced challenges with traditional mechanical conveying methods for resin powder. Existing bucket elevators and screw conveyors caused frequent blockages, dust emissions, and product degradation. The plant needed a closed-loop, automated system that could convey resin powder over a distance of 150 meters with multiple discharge points, while maintaining material integrity and minimizing maintenance. The specific requirements included a conveying capacity of 12 tons per hour, a maximum particle size of 500 microns, and the ability to handle both virgin and recycled resin powders with varying moisture content. After evaluating several international suppliers, the client chose headpowder due to its proven track record in pneumatic conveying projects across Asia and its customized engineering approach for resin powder applications.
Headpowder designed a dense-phase positive pressure pneumatic conveying system specifically tailored for the resin powder application in Palembang. The system utilizes a rotary airlock feeder at the material inlet, a high-pressure Roots blower rated at 55 kW, and a series of wear-resistant conveying pipes made of stainless steel with ceramic-lined bends to minimize erosion. The positive pressure configuration ensures that the resin powder is pushed through the pipeline at a controlled velocity, typically between 8 and 12 m/s, which prevents particle breakage and reduces energy consumption compared to dilute-phase systems. The system includes four branch lines leading to different silos and mixing stations, each equipped with automated diverter valves and level sensors for precise material distribution. A centralized PLC control panel with HMI touchscreen allows operators to monitor flow rates, pressure drops, and filter condition in real time, ensuring continuous and stable operation.
This Indonesia pneumatic conveying case highlights several technical innovations. First, the dense-phase positive pressure design reduces air consumption by up to 40% compared to conventional dilute-phase systems, making it more energy-efficient for the Palembang plant. Second, the system incorporates a proprietary air injection system at the discharge end to prevent material bridging and ensure complete emptying of the pipeline after each batch. Third, all contact surfaces are constructed from 304L stainless steel with a surface roughness of less than 0.8 micrometers, meeting the hygiene standards required for resin powder used in food-grade packaging applications. Fourth, the pneumatic conveying system includes a pulse-jet dust collector at the vent line, achieving a filtration efficiency of 99.9% for particles down to 1 micron, thus maintaining a clean working environment. The entire system was pre-assembled and tested at headpowder's facility in Shandong, China, before shipment, reducing on-site installation time by 30%.
The installation of the positive pressure pneumatic conveying system at the Palembang, Indonesia site was completed within 45 days, including civil works, pipe routing, and electrical integration. Headpowder sent a team of two senior engineers to supervise the commissioning and train local operators. The system has been running continuously for over 18 months with a reliability rate of 98.5%. The resin powder conveying capacity achieved 13.2 tons per hour, exceeding the design specification. The client reported a 70% reduction in dust emissions and a 50% decrease in maintenance costs compared to the previous mechanical system. The product quality remained consistent, with no measurable change in particle size distribution or moisture content after conveying. This successful Indonesia pneumatic conveying project has become a reference case for other resin powder manufacturers in the region, including facilities in Jakarta and Surabaya.
The headpowder-supplied positive pressure pneumatic conveying system for resin powder in Palembang includes the following major components: (1) a 10 m³ feed hopper with a screw feeder and level indicators; (2) a rotary airlock valve with a capacity of 15 m³/h, equipped with a variable frequency drive for speed control; (3) a Roots blower unit with a discharge pressure of 0.8 bar(g) and a flow rate of 120 m³/min, fitted with a silencer and inlet filter; (4) a conveying pipeline of DN150 schedule 40 stainless steel, with a total length of 180 meters including 12 bends; (5) four receiving silos each with a capacity of 30 m³, equipped with high-level and low-level alarms; (6) a pulse-jet dust collector with 24 filter bags and a compressed air cleaning system; (7) a PLC control cabinet with remote monitoring capability via Ethernet. All components are designed to withstand the tropical climate of Palembang, including high humidity and ambient temperatures up to 40°C, with special corrosion protection coatings applied to exposed surfaces.
Headpowder followed a structured project management approach for this resin powder pneumatic conveying project. The engineering phase included 3D modeling of the layout, computational fluid dynamics (CFD) analysis of the conveying line, and stress analysis of the pipe supports. Quality control was implemented at every stage: raw material inspection, welding procedures qualified to ASME standards, hydrostatic testing of the pipeline, and functional testing of the control system. The project was delivered on time and within budget, with a full set of documentation including piping and instrumentation diagrams (P&ID), operation and maintenance manuals, and spare parts lists. Headpowder also provided a two-year warranty and a service agreement for annual inspection and maintenance support.
