Ferrous sulfate powder is a finely divided, high-density crystalline material widely used in water treatment, agriculture, pigment manufacturing, and chemical processing. Its particles are abrasive and mildly corrosive, and the powder can absorb moisture, cake, and bridge inside hoppers and pipelines. Therefore, a robust pneumatic conveying solution must control gas velocity, minimize contact with metal surfaces, and maintain a stable solids-to-air ratio. A well-engineered system not only moves powder efficiently but also preserves its chemical integrity and prevents dust escape.

Our customized ferrous sulfate powder pneumatic conveying systems are designed around the exact flow properties of your material. We begin with bulk density, particle size distribution, angle of repose, moisture content, and cohesion testing. These data determine the optimum conveying mode: dilute phase or dense phase, vacuum or positive pressure, and choose the correct pipe diameter, bend radius, and air mover. For ferrous sulfate, dense-phase systems are commonly recommended because lower velocities reduce pipeline erosion and particle attrition, while gentle slug flow prevents material degradation.

Positive-pressure dense-phase conveying uses compressed air to push material at high solids loading and low velocity. The powder moves in plugs through the line, reducing wear and air consumption compared with dilute-phase transfer. This approach is especially effective for iron salt powders that are slightly hygroscopic or prone to segregation. Vacuum conveying can also be implemented for bag dumping and dust-free unloading, where a pickup nozzle transfers powder from open containers or supersacks into the process line without creating dust clouds.

Every system includes a dedicated air supply package, feed device, conveying line, and receiver. For ferrous sulfate powder, the feed device is often a rotary airlock, screw feeder, or venturi eductor, depending on pressure differential and material characteristics. The air supply may be roots blowers, screw compressors, or regenerative blowers, selected to provide the required pressure and flow. Receivers are fitted with cyclonic or bag filters to separate powder from transport air, ensuring clean discharge and minimal product loss.

Pipeline routing is one of the most important elements of a reliable conveying design. Long horizontal distances, vertical lifts, and multiple discharge points require balanced pressure profiles and proper bends. Long-radius elbows or ceramic-lined bends are recommended for ferrous sulfate to minimize erosion at impact points. The line should be as short and straight as possible, with an adequate slope for drainage and cleaning. Our engineers model the entire route using advanced simulation tools to verify that the material will not stall or stratify.

Material handling safety is critical. Ferrous sulfate dust can irritate eyes, skin, and the respiratory tract, so dust-tight connections, explosion-suppression options, and easy maintenance access are essential. We integrate rotary valves with pressure relief, filter receivers with reverse-pulse cleaning, and inert-gas purging when required. PLC controls manage conveying sequence, material level, pressure, and air flow. Sensors detect line blockage or filter pressure, and the system automatically adjusts purging or alerts maintenance.

Typical applications include unloading ferrous sulfate from bulk bags, moving powder to dissolution tanks for water treatment, feeding micronutrient blending lines, dosing pigment reactors, and transferring recycled powder between process stages.

We also offer laboratory testing, retrofits, spare parts, and operator training for a complete long-term solution.
