Screw Conveyor

Screw Conveyor Application

Screw conveyor is specially designed for material transportation. Used for: slaughtering, pet food, fish meal.

1. Food Processing: Screw conveyors are used to move food products, such as grains, flour, sugar, and spices, through the various stages of processing.
2. Agriculture: Screw conveyors are used to move agricultural products, such as grain, feed, and fertilizer, through processing and storage facilities.
3. Pharmaceuticals: Screw conveyors are used to move powders, granules, and other materials through the manufacturing process for pharmaceutical products.
4. Mining: Screw conveyors are used to move ore, coal, and other mining products through processing and storage facilities.
5. Construction: Screw conveyors are used to move cement, sand, gravel, and other construction materials.
6. Power Generation: Screw conveyors are used to move coal, ash, and other materials in power generation facilities.
7. Pulp and Paper: Screw conveyors are used to move wood chips, pulp, and other materials in pulp and paper mills.
8. Chemical Processing: Screw conveyors are used to move chemical products, such as acids, alkalis, and solvents, through processing facilities.
9. Waste Management: Screw conveyors are used to move waste materials, such as sewage, through treatment facilities.
10. Recycling: Screw conveyors are used to move recyclable materials, such as paper, plastic, and metal, through recycling facilitie

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. The screw conveyor is commonly used to transport materials such as powders, granules, and small pieces, as well as liquids and sludges, in a variety of industries, including agriculture, mining, food processing, and waste management. Screw conveyors are versatile and can be used in both horizontal and vertical configurations, and can be powered by an electric motor or by a diesel engine. They are relatively simple and efficient in their design, and can be easily disassembled for cleaning or maintenance.

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.
