Boron nitride (BN) is an advanced powder used in ceramics, release agents, electronics, thermal management, and cosmetics. Moving BN powder safely requires a dedicated pneumatic conveying system that prevents dust escape, contamination, and material degradation. Our engineered solution transfers boron nitride from storage hoppers to process equipment with stable flow and low product loss, while maintaining full operational safety.

BN powders are fine and light, so they tend to dust, segregate, and cake. Standard equipment can cause plugging or high product waste. The conveying velocity must be optimized: too high can degrade particles or create dust, while too low may block the line. Our design process analyzes particle size, bulk density, and flowability to choose the correct mode.

Depending on distance, throughput, and BN grade, we offer dilute-phase pressure conveying, dense-phase low-velocity conveying, or vacuum conveying. Dense-phase is recommended for high-purity or fragile powder because it reduces attrition and uses less gas. Vacuum conveying is convenient for feeding from bags or containers. All modes are fully enclosed and tailored to the site layout.

A complete system includes feed hopper, rotary airlock, blow tank, conveying pipe, receiving bin, dust collector, and PLC controls. The rotary valve feeds powder steadily; the blow tank or pressure vessel supplies compressed air or nitrogen; smooth-bend piping reduces wear and accumulation; the receiving bin separates powder from the conveying air.

BN particles are very fine, so filtration is a key factor. We install high-efficiency cartridge or bag filters with pulse-jet cleaning. The filters capture fine boron nitride powder and return it to the product stream. This prevents material loss, keeps exhaust air clean, and maintains stable pressure in the conveying line.

Automation and safety are built into every system. PLC and HMI controls monitor pressure, temperature, valve position, and motor status. Static grounding, pressure-relief devices, and optional inert nitrogen conveying protect against dust explosions. Leak-proof connections prevent product release. The system can be connected to your plant network for remote supervision.

Each boron nitride conveying solution is customized to process requirements. We adapt capacity, conveying distance, number of delivery points, and material contact surfaces. Stainless steel 304 or 316L construction and polished interiors are available for high-purity work. We can also integrate batching, weighing, packing, or multi-line distribution into the conveying system.

The system is suitable for many sectors. In ceramics, BN is used in sintered parts and spray-dried granules. In metals, it is used as a mould release agent. In electronics, it is used in thermally conductive fillers. In cosmetics, it improves powder texture. Each process benefits from a closed, dust-free conveying line that keeps product quality consistent.

We also offer retrofits for existing conveying lines: changing rotary valves, upgrading filters, optimizing pipe diameter, or installing more accurate metering. Our engineers provide installation supervision, commissioning, operator training, and after-sales support. Maintenance plans reduce downtime and keep the system running at maximum efficiency.

A well-designed boron nitride pneumatic conveying system provides safe, efficient, and reliable powder transfer. It reduces manual handling, prevents contamination, lowers energy consumption, and improves yield.
