Anhydrous calcium chloride pellets present unique challenges in pneumatic conveying due to their strong hygroscopic nature and tendency to bridge or cake. Traditional conveying systems often lead to line blockages, product degradation, dust emission, and frequent maintenance downtime, directly impacting production efficiency and safety. Headpowder delivers a tailored pneumatic conveying solution specifically designed to handle anhydrous calcium chloride pellets, addressing these operational pain points with robust engineering and customizable configurations.

Customer Pain Points

Operators of anhydrous calcium chloride handling processes face recurring difficulties: moisture absorption causes pellets to agglomerate inside pipelines and hoppers, resulting in clogged conveying lines and reduced flow rates. Mechanical wear from abrasive granules shortens equipment lifespan. Dust generation during transfer creates workplace hazards and product loss. Moreover, standard conveying systems lack the flexibility to adapt to varying pellet sizes, moisture levels, or plant layouts, forcing frequent manual intervention and unplanned stoppages.

Material Characteristics

Anhydrous calcium chloride pellets are highly deliquescent—they rapidly absorb atmospheric moisture, forming sticky surfaces and eventual dissolution. The pellets have a bulk density ranging from 0.8 to 1.2 g/cm³, particle size typically between 1–6 mm, and moderate abrasiveness. Their low melting point and tendency to release heat upon hydration demand careful temperature and humidity control throughout the conveying process. Hygiene and containment are also critical, as the material can cause corrosion to unprotected metals and irritation upon contact.

Our Solution – Customized Pneumatic Conveying System

Headpowder designs and manufactures dedicated pneumatic conveying systems for anhydrous calcium chloride pellets. Each system is engineered around the specific material properties and site constraints. We offer dense-phase or dilute-phase conveying modes, complete with dehumidified air supply, sealed rotary valves, anti-bridging hopper designs, and corrosion-resistant contact surfaces. The system is fully automated via PLC control, enabling precise material metering, gentle handling, and low-energy operation. Customization options include conveying distance up to 200 meters, throughput from 500 kg/h to 20 t/h, and integration with existing upstream/downstream equipment.

Solution Advantages

Our approach directly resolves the common pain points: the closed-loop pneumatic circuit with dried process air prevents moisture ingress, eliminating pellet stickiness and blockages. Wear-resistant materials (e.g., stainless steel 316L, ceramic liners) extend service life. Low-velocity dense-phase transport reduces dust generation and product attrition. The modular design allows rapid reconfiguration for future capacity changes. Advanced sensors and auto-purge cycles keep the system running reliably with minimal operator oversight. The result is higher uptime, consistent product quality, and safer working conditions.
