What is a Vertical Spiral Screw Elevator

Moving powder or granules from low to high doesn't have to take up half your floor space. Our vertical spiral screw elevator does the job straight up, in a fraction of the footprint you'd need for a regular conveyor or bucket system.

So how does it work? A rotating screw inside a sealed tube gently pushes material upward. No shaking, no tumbling. Just a steady, even rise from the feed point right up to your discharge height. The motion is smooth enough that your product stays exactly as it should be—no mixing, no separation of different particle sizes, no dust clouds.

This setup saves you from constant cleaning or product waste. It runs quietly, handles a wide range of materials, and fits neatly into tight production lines. You can set it and forget it, knowing that your material moves at a predictable rate, batch after batch.

Installation is straightforward. Maintenance is simple. And because the casing is closed, you keep your product in and contaminants out.

If you are tired of bulky equipment that fights for space or unreliable lifts that break your material flow, this elevator gives you a cleaner, simpler way to go vertical. Let's talk about your material and your height.

Unlike traditional horizontal conveyors or bulky bucket elevators, our spiral lift conveyor leverages centrifugal force and friction to overcome gravity, ensuring a smooth, steady, and controlled material flow without product segregation.

How does a Vertical Spiral Screw Elevator work?

Material enters through the bottom inlet. A rotating spiral flight then pushes it straight up along the enclosed vertical casing. The sealed design keeps dust inside and protects your workshop from contamination. Once the material reaches the top, it flows out smoothly through the discharge outlet, ready for the next processing step, packaging line, or storage silo. The whole move is steady and controlled, so your product stays uniform from bottom to top.

Controlled feeding starts with bulk materials such as powders, chemical granules, or food ingredients being fed into the bottom inlet hopper. Then the helical action conquers gravity as the heavy-duty motor drives the central shaft and the high-precision screw flight rotates rapidly, creating a mechanical lifting force that pushes the material upward along the spiral track. The safe and dust-free enclosure means the material travels vertically through a completely sealed casing, ensuring zero dust leakage and protecting your workshop environment from contamination. Finally, efficient discharge happens once the material reaches the top, where it is smoothly expelled through the outlet directly into your processing machines, packaging lines, or storage silos.

What are the advantages of Spiral Lift Conveyor?

This vertical conveying system is engineered exclusively for powder materials with a fully sealed, dust-free design that eliminates scattering and ensures reliable pollution control.

Frequently Asked Questions About Spiral Lift Conveyors

Q1: How do I choose the right size of vertical screw elevator for my powder?

A: It depends on your material characteristics (bulk density, moisture), required lifting height, and capacity. Contact Dahan engineers for a free sizing calculation.

Q2: Can this spiral conveyor handle sticky or fragile materials?

A: For sticky powders, we design shaftless screw conveyors or special surface coatings to prevent clogging. For fragile granules, we adjust the RPM to ensure gentle handling.

Q3: Does the equipment meet food-grade sanitation standards?

A: Yes, our stainless steel spiral lift conveyors are designed with smooth welds and easy-clean hatches to comply with strict food and pharmaceutical hygiene regulations.
