What is a Screw Conveyor

A screw conveyor is a type of mechanical conveyor that uses a rotating helical screw blade, called a “flighting,” within a tube or trough, to move bulk materials horizontally or at an incline. It is a prevalent choice for transferring materials ranging from powders, granules, and small fragments to liquids and sludges across diverse sectors, including agriculture, mining, food processing, and waste management.Screw conveyors exhibit adaptability, functioning effectively in both horizontal and vertical setups, and can be propelled by either an electric motor or a diesel engine.Their design is characterized by its simplicity and efficiency, allowing for straightforward disassembly to facilitate cleaning or maintenance procedures.

Design characteristics and options

(1)Standard screw conveyor

1. U shape screw conveyor is designed instainless steel material, increase the corrosion resistance of equipment.

2. Between screw shaft, we use alloy steel pipe and spiral blade welding, select screw blade with standard diameter, screw pitch , to guarantee material delivery stability.

3. The design for low-carbon steel wear plate avoid the direct friction between blade and body, increase the service life of the equipment.

4. Independent drive and design from leading part let the overhaul more convenient.

5. Cover is designed withstainless steel, sealed with body, create a closed workspace, prevent colour leakage.

6. Leg is designed withstainless steel.

7. Stand material is carbon steel with galvanized or colour painted.

8. Covermaterial is stainless steel.

(2) Pre-heating (or water cooled) screw conveyor

1. Increased jacket and one set pipe valve at bottom of U shape groove

2. When the internal medium of system jacket is saturated steam, screw conveyor preheat the material in transportation as

3. Preheating screw conveyor.

4. When the internal medium of system jacket is cooled water, screw conveyor cool the material in transportation as water cooled screw conveyor.

(3) Drain screw conveyor

1. Design the strainer at the bottom of U groove, the diameter of drainer is adjusted according to the material.

2. The design of drainer will make pre-extrusion and collect the liquid or fat  in transportation of material, so improve the oil pressing efficiency.

(4) Air cooled screw conveyor

1. At the top of screw, we designed air cooled system, material is cooled by air in transportation.

2. Used for cooling less material, cooling capacity is calculated according to the material throughput.

Screw Conveyor FQA

Screw conveyors are a type of mechanical conveyor that use a rotating helical screw blade, also known as a “flighting,” to move liquid or granular materials. They are commonly used in industrial settings for the transportation of bulk materials such as powders, grains, and small parts. Here are some frequently asked questions about screw conveyors:

1.How does work?

It works by rotating a helical screw blade, or flighting, inside a tube or trough. As the screw rotates, it pushes material forward, moving it along the conveyor.

2.What materials can be transported ?

Screw conveyors possess the capability to transfer a diverse range of materials, encompassing powders, granules, crystals, pellets, and small components. They find frequent application across industries such as food, agriculture, pharmaceuticals, and mining.

3.What are the advantages of using a screw conveyor?

They exhibit simplicity, efficiency, and versatility. They excel in transporting materials both horizontally and on inclines, offering easy adaptability to various scenarios. Furthermore, they are economically viable and demand minimal maintenance.

4.What are the disadvantages ?

Screw conveyors are not suitable for materials that are easily compacted or have a tendency to “bridging”, also it’s not suitable for material with high moisture content, high temperature, and corrosive materials.

5.How can I determine the right size ?

Sizing a screw conveyor depends on factors like the conveyed material, desired conveyance speed, and required capacity.
