Mechanical conveying systems
Simple and proven, screw conveyors and rotary valvesIn the area of ‘mechanical conveying’, both rotary valves and screws can be used. The design lines solids Basic, solids Clean and solids Hygienic are available. The Hosokawa Solids Solutions rotary valves are also optionally available as a protection system according to the ATEX directive.
Rotary valves are used for dosing, feeding or discharging fine-grained and dusty products or granulates.
Screw conveyors are divided into tubular screws and trough screwsaccording to the type of construction. The screw helix can be designed as a full-bladed screw or as a shaftless screw. They are used in heavy industry as well as in the fine chemicals sector. Screw conveyors essentially consist of a conveyor trough or pipe, the screw conveyor consisting of a screw shaft and helix and the drive unit. Mild steel, stainless steel, wear-resistant and heat-resistant materials are used.
Our experts select the most suitable rotary valve or screw for you based on the product properties, working conditions and tasks to be performed.
