Heavy calcium powder, or ground calcium carbonate, is widely used in plastics, rubber, coatings, papermaking, construction, and chemical industries. Because it is abrasive, dusty, and often fine, conveying must be safe and efficient. Traditional methods can cause dust leakage, material loss, and high labor costs. Pneumatic conveying uses air flow through sealed pipelines to eliminate these problems. Our heavy calcium pneumatic conveying solution provides clean, continuous, automated transfer that meets modern production standards.

Our system includes a Roots blower, rotary airlock feeder, conveying pipeline, cyclone separator, bag filter, pressure sensors, and PLC control panel. Raw powder enters through a sealed feeding device, mixes with high-speed air, and moves to the discharge point. A cyclone and bag filter separate powder from air, while clean air is released or recycled. This closed-loop design ensures stable transfer, prevents dust emission, and reduces product loss.

We offer dilute phase and dense phase pneumatic conveying systems. Dilute phase uses high air velocity and low pressure, suitable for short distances and moderate capacities. Dense phase uses low air velocity and high pressure to push material plugs through the pipeline, reducing wear and particle degradation. For abrasive heavy calcium powder, dense phase is often recommended because it lowers impact against pipe walls, extends service life, and saves energy.

When designing a customized heavy calcium pneumatic conveying solution, our engineers evaluate bulk density, particle size, moisture, angle of repose, abrasiveness, conveying distance, elevation change, and required throughput. These factors determine the pipeline diameter, air velocity, pressure drop, and power consumption. We also consider the existing plant layout, operating procedures, and safety requirements. Correct component selection avoids pipe wear, material buildup, airlock leakage, and excessive fines generation, ensuring stable operation and consistent final product quality.

Key equipment includes ceramic-lined wear-resistant elbows, abrasion-resistant straight pipes, adjustable-speed rotary feeders, high-efficiency bag filters, pressure relief valves, and explosion-proof electrical controls. Ceramic-lined elbows are important because heavy calcium powder moving at high speed can quickly erode ordinary carbon steel. The fully sealed pipeline prevents dust leakage at joints and valves. Automatic reverse-pulse cleaning maintains filter performance, and the control system adjusts operating parameters in real time to prevent blockage and maintain a stable material-to-air ratio.

This heavy calcium pneumatic conveying solution brings multiple benefits to production lines. It eliminates dust pollution, reduces raw material loss, lowers labor costs, and improves overall efficiency. Because the pipeline is sealed, operators have no direct contact with the powder, minimizing health and safety risks. The continuous process can be integrated with grinding, drying, sieving, storage, packing, and truck loading. Automated controls prevent overpressure and blockage, while recorded data helps factories maintain stable product quality and traceable production management.

The system conveys heavy calcium powder from mills to silos, between process stages, or directly to packaging machines. It handles fine powders from 200 mesh to 1250 mesh and coarser granular materials. Typical applications include silo storage, batching, blending, direct feeding to extruders or mixers, and bulk truck loading. Our engineers can design single-line or multi-point conveying networks with automatic switching valves to send materials to different destinations as required.

As a professional heavy calcium pneumatic conveying manufacturer, we provide complete services from site survey, system design, and equipment fabrication to installation, commissioning, and operator training. We offer capacities from 1 t/h to over 50 t/h and conveying distances up to several hundred meters. The layout can be horizontal, vertical, or multi-bend. Every solution is customized to the customer's site and budget, ensuring safe operation, lower energy use, and long-term reliability.
