Product Overview

A vertical screw conveyor lifts bulk material straight up in a single pipe, which makes it the most space-efficient way to fill silos, bins and truck tanks where an inclined belt or bucket elevator will not fit. This 160mm unit handles grain, seed, pellets and powder at 8-10 T/H with a lifting height from 6m to 10m.

Key Features

• Vertical screw inside a seamless steel pipe with flange joints, assembled on site without welding.
• Top-mounted drive with anti-rotation device and thrust bearing to carry the column weight.
• Adjustable feed gate at the inlet hopper to control the filling rate and avoid overloading.
• Centrifugal discharge head directs material into the silo without dust spillage.
• Support brackets for wall or silo mounting, no extra steel structure needed.
• Optional level sensor and automatic stop to prevent silo overfilling.

Technical Parameters

Note: all dimensions, capacity and motor power are customized according to the material bulk density, conveying distance and installation angle.

Applications

• Grain silos and flat warehouses - filling from ground level
• Feed mills - lifting mash and pellets to mixing bins
• Flour mills - vertical transfer between floors
• Chemical and plastic plants - powder and pellet lifting

Selection & Customization

Vertical conveyors require the inlet to be flooded evenly. Tell us the material, bulk density, lifting height and silo top opening size, and we will size the pipe, speed and motor. Stainless steel pipe, explosion-proof motor and a dust-free telescopic discharge spout are available.

Packing & Delivery

The machine is wrapped with waterproof film, fixed on a steel pallet and packed in a fumigation-free export wooden case. Spare parts, motor and control cabinet are packed separately. Delivery time is 7-15 working days after deposit, shipping by sea, rail or air per your forwarder.

FAQ

Q: Why does the motor need a thrust bearing?

A: The whole weight of the vertical screw column rests on the top bearing, so a heavy duty thrust bearing and anti-rotation device are essential.

Q: What is the maximum lifting height?

A: Up to 18m with the 200mm model; beyond that a bucket elevator is usually more economical.
