| Screw Conveyors for Powder and Granular Materials

VOLDE screw conveyor systems are reliable mechanical transfer solutions designed for the controlled conveying and feeding of powder and granular bulk solid materials between process equipment. They provide an enclosed, orderly product flow between silos, bins, mixers, dosing systems, extruders, or process lines. Depending on the application, they can be used as a short-distance dosing screw or as a conveying screw for longer lines. Thanks to horizontal or inclined layout options, they easily adapt to different facility layouts.

• Screw conveyor design suitable for conveying powder and granular material on horizontal or inclined lines
• A wide capacity range with diameter options of 114, 139, 168, 219, 273, 323, and 406 mm
• Use as a precision dosing screw over short distances or as a conveying screw on longer lines
• Custom-designed feed inlets suitable for silos, bins, and process equipment
• Clean, safe transfer that minimizes dust emissions thanks to the enclosed body structure
• Pitch and body geometry optimized according to different product densities and flow characteristics

| Process-Compatible Mechanical Design

VOLDE screw conveyors are designed through engineering calculations that take into account the flow properties, abrasiveness, and process conditions of the material to be conveyed. The drive system, screw pitch, bearing, and sealing elements are selected according to the application, ensuring long-lasting, stable operation. This creates a reliable mechanical infrastructure for both continuous conveying and precise process feeding applications.

• The motor-gearbox drive unit can be positioned on either the feed or discharge side
• Standard carbon steel screws, or HARDOX pitch options for abrasive materials
• Sealing and bearing systems selected according to material properties
• Dual-outlet or bidirectional screw configurations
• Carbon steel, AISI 304, or AISI 316 stainless manufacturing options
• Low maintenance requirements thanks to long-life bearing and support systems
• Easy maintenance and service access via inspection hatches
• A reliable, compact mechanical conveying solution for industrial processes
