Alumina powder pneumatic conveying is an essential process in aluminum oxide production. Our customized solutions handle powder efficiently, safely, and with minimal degradation. Whether you need a new line or a retrofit, we engineer systems according to capacity, distance, layout, and material properties. Advanced airflow technology, precision components, and intelligent controls ensure stable, dust-free transfer in every application.

Alumina powder is fine, abrasive, and slightly hygroscopic. It requires careful selection of conveying velocity, air volume, and pipeline material. Our design begins with material analysis and on-site measurements. We calculate the optimal solid-to-air ratio to reduce pipe wear and energy use while maintaining fluidization. The result is a safe, economical, and high-performance conveying system for refineries, smelters, ceramics plants, and catalyst plants.

We offer dilute-phase and dense-phase pneumatic conveying solutions. Dilute phase uses high-velocity air to carry powder over short distances and moderate capacities. Dense phase uses low velocity and high pressure to push material in slugs, reducing wear and air consumption. For abrasive alumina, dense phase is often preferred. Our engineers evaluate your route, capacity, and material, then select the most reliable and energy-efficient mode for your project.

Each system uses high-performance equipment: rotary airlock feeder, roots blower or compressor, feed hopper, conveying pipe, wear-resistant bends, receiving silo, bag filter, dust collector, and control panel. We integrate level sensors, pressure transmitters, flow meters, and automated valves. For abrasive alumina, pipes and bends are ceramic-lined or made of wear-resistant alloys. The rotary feeder provides accurate, air-tight feeding; the filter separates powder from air and returns product to storage or process.

Depending on site conditions, we configure positive pressure, negative pressure, or combined systems. Positive pressure is ideal for one-to-many delivery from a single feed point to multiple silos. Negative pressure is suitable for vacuum loading from bulk bags, bins, or truck hoppers. All configurations are fully sealed to prevent dust emission, comply with environmental regulations, protect operator health, and reduce product loss.

Customization is at the core of our service. We provide capacity evaluation, route layout, elevation profile, bend radius, pipe diameter, air consumption calculation, motor power selection, and PLC programming. We also supply explosion-proof electrical equipment, remote monitoring, and touchscreen HMI. The control system can integrate with DCS or MES platforms for real-time diagnostics, alarm management, and automated start-stop. All parameters are monitored continuously to ensure stable conveying and low operating cost.

Installation and commissioning are handled by our experienced engineers. We provide detailed drawings, erection guides, and on-site supervision. During commissioning, we optimize air velocity and feed rate to reach the specified capacity and pressure. We also train your operators and maintenance staff. After-sales service includes spare parts, inspections, wear-part replacement planning, and remote support. Our goal is maximum uptime, low maintenance costs, and a long service life for every component.

Our alumina powder pneumatic conveying systems are widely used in aluminum smelting, refractories, ceramics, catalyst manufacturing, and chemical processing. They handle metallurgical-grade, calcined, activated, and high-purity alumina. We support multi-point feeding to silos, furnace hoppers, packing machines, and mixing stations. Every project includes P&ID diagrams, general arrangement drawings, electrical schematics, and operation manuals. Choosing our solution means lower energy consumption, less dust, less waste, safer workplaces, and stable production.
