Synthetic graphite is a high-value material widely used in lithium-ion battery anode materials, refractory products, carbon brushes, semiconductor components, and advanced composites. The particles are hard but brittle, so careless handling can cause cracks, broken grains, and unwanted fines. In Singapore, industrial facilities must meet strict quality, safety, and environmental standards. The existing transfer method caused unacceptable product degradation. Therefore, the customer needed a gentle yet efficient conveying method. Headpowder proposed a dense-phase pneumatic conveying system designed specifically for low breakage.

Dense-phase conveying works by using compressed gas to push a compact mass of powder through a pipeline at low velocity. This is very different from dilute-phase conveying, where particles are suspended in a high-speed air stream and collide with walls. In dense-phase flow, the material moves in stable plugs or dunes, greatly reducing collisions and friction. This behavior is ideal for synthetic graphite because it preserves the particle size distribution and minimizes the generation of fines. In addition, the system operates with a high solid-to-air ratio, so less compressed air is consumed and the product remains stable during transport.

In this Singapore project, Headpowder used a pressure vessel blow tank as the conveying source. The synthetic graphite is loaded into the blow tank through a charging valve, sealed, and then pressurized with filtered compressed air. When the preset pressure is reached, the outlet valve opens and the material is driven into the pipeline. Sensors and a programmable logic controller regulate pressure, valve timing, and backpressure to maintain steady plug flow. This careful control prevents sudden pressure surges that could damage brittle particles and ensures repeatable performance from batch to batch.

Pipeline design was another critical factor in achieving low breakage. Headpowder selected pipes with smooth interior surfaces and used large-radius bends wherever the line changed direction. Diverter valves and reducers were chosen to keep cross-section changes gradual and avoid turbulence. The receiving hopper is equipped with a vent filter to separate air from the graphite and ensure dust-free operation. The whole system is fully enclosed, preventing contamination and helping the plant meet strict Singaporean safety and environmental requirements. During commissioning, the synthetic graphite retained its original particle shape, fines generation was very low, and the rated conveying capacity was reached.

The low-breakage dense-phase system also brings economic and operational advantages. Low conveying velocity reduces pipeline wear, so maintenance intervals are longer and downtime is minimized. Gas consumption is much lower than for dilute-phase systems, and the compact equipment layout fits easily into an existing Singapore production building. The PLC-based control allows automatic operation with minimal operator attention. The results have remained consistent since start-up: no blocked lines, no visible dust, and no significant change in product quality. These benefits combine to give the customer a stable, clean, and cost-effective conveying solution for a sensitive material.
