Magnesium oxide (MgO) is a versatile bulk powder used in refractories, chemicals, environmental protection, agriculture, and pharmaceuticals. Pneumatic conveying provides an enclosed, flexible, and automatic way to move MgO to process equipment. Our custom solutions match every system to the exact material behavior and site conditions.

The key benefit is a sealed pipeline. It prevents dust escape, limits moisture pickup, protects product quality, and eliminates spillage. The compact line can be routed around existing equipment or into difficult areas. With fewer moving parts than mechanical conveyors, maintenance is simple and operation is clean.

MgO powder can absorb moisture, form lumps, stick to pipe walls, and cause abrasion. A reliable system controls air quality, adjusts gas speed, and uses wear-resistant bends and pipes. This prevents blockages and reduces downtime.

Every magnesium oxide conveying system is custom engineered. We start with material testing, capacity calculation, route design, and a site survey. Then we choose positive pressure, vacuum, or combined conveying. The layout fits your plant, avoids interference, and makes future expansion easier.

For long distances and high throughput, dense phase conveying is often preferable. A pressure vessel feeds MgO into the pipe, and compressed air pushes the powder forward in slow-moving slugs. Low velocity reduces wear, protects particles, and uses less energy per ton.

Dilute phase conveying uses high-velocity air to suspend MgO in the pipeline. It is economical for short and medium distances. Material stays airborne until it reaches a receiver or cyclone. Many magnesium oxide transfer lines use this method with excellent results.

Vacuum conveying is ideal for loading MgO from bags, drums, silos, or process machines. Negative pressure keeps dust from escaping into the workplace. Operators dump material safely and cleanly, while the system moves powder to a centralized collection point.

Main components include a blower or compressor, rotary feeder, screw conveyor, blow tank, rotary airlock, valves, pipeline, bends, receiving hopper, dust collector, and control panel. Every part is matched to the material's abrasiveness and sealed to avoid leakage. Ceramic-lined or long-radius bends are used at wear points.

We can also integrate dryers, dehumidifiers, air coolers, moisture probes, level sensors, weighing hoppers, and batching controls. For MgO, dry conveying air is essential. These additions keep powder free-flowing and improve accuracy.

Automation is built into every system. A PLC controls filling, pressurizing, conveying, filtering, and discharging. A touchscreen shows real-time status, alarms, and production data. This reduces operator workload, improves repeatability, and lets the line run continuously with minimal supervision.

Benefits include dust-free operation, lower labor cost, better safety, and stable product quality. The sealed system prevents contamination and reduces raw material loss. Compact pipes save floor space. Low-wear components and fewer moving parts lower maintenance expenses.

Applications include feeding refractory mixers, dosing MgO into reactors, filling storage silos, supplying packaging machines, and adding powder to water treatment or desulfurization systems. We adjust pipe size, air velocity, pressure, and equipment configuration to reach the desired capacity.

Our scope includes installation, commissioning, and long-term service. Each system is tested before delivery. On site, engineers adjust parameters and train operators. We provide spare parts, documentation, and preventive maintenance plans.

Choosing a custom magnesium oxide pneumatic conveying solution requires a partner who understands powder handling. We combine proven technology with practical experience in abrasive and hygroscopic materials. We deliver a safe, efficient, and economical design for complete plants or single lines.
