Screw Conveyor Design – Screw Feeder CAD Model for Bulk Material Transport
Structural Steel Body | Stainless Steel Shaft & Helix | 1.5kW Drive
This screw conveyor design delivers a complete screw feeder CAD model for transporting bulk materials like gypsum, lime, cement, and flour. The body is built from structural steel S355JR, with the shaft and helix in stainless steel 1.4301 for material contact durability. A 1.5kW gear motor drives the screw at up to 50rpm, giving you a proven reference design ready for CAD modification.
