Trough screw conveyors are designed with U-shaped troughs, which are the most common trough shape and are suitable for almost all applications. Remove cover for full access to screws and hangers; makes screw conveyors less maintenance-intensive for horizontal or slightly elevated mechanical conveying of powders, granules and lumps in the food, grain and non-food industries bulk material. With proper design, trough screw conveyors can also be used for batching, wetting, mixing or crushing of bulk materials.
Trough screw conveyor pushes the materials forward through the rotation of the screw screw. It has the advantages of large transportation capacity, stable operation, low energy consumption, and easy maintenance. Commonly used in mining, building materials, chemical industry and other industries, it is used in raw material transportation, packaging transportation, waste processing and other process links to improve production efficiency and realize the automation of the production process.
Trough screw conveyors are used in a wide range of industries and applications to move bulk materials horizontally or at a slight incline. Some of the common applications of trough screw conveyors include:
1. Agriculture:Are used to move grains, seeds, and other agricultural products from storage to processing or packaging facilities.
2. Chemicals: Are used to transport chemicals, such as powders, pellets, and granules, from one process to another.
3. Food and Beverage: Used to move food products, such as flour, sugar, and spices, from storage to processing or packaging facilities. They are also used to transport beverages, such as beer and soft drinks, from one process to another.
4. Mining: Used to transport ores, minerals, and other mining products from one location to another.
5. Pharmaceuticals:Used to move pharmaceutical powders, tablets, and capsules from production to packaging facilities.
6. Waste Management: Trough screw conveyors are used to move waste materials, such as municipal solid waste, from collection points to processing or disposal facilities.
7. Water Treatment: Used to move sludge and other waste materials from water treatment facilities to processing or disposal facilities.
8. Plastics: Trough screw conveyors are used to move plastic pellets, powders, and granules from production to packagingfacilities.
9. Construction: Used to transport construction materials, such as sand, gravel, and cement, from one location to another.
10. Recycling: Are used to move recyclable materials, such as paper, plastic, and metal, from collection points to processing facilities.
Classification by driving method
Single shaft trough screw conveyor: When the length of the trough screw conveyor is less than 35m, it is a single-axis driven screw.
Double shaft trough screw conveyor: When the length of the trough screw conveyor is greater than 35m, it is a double-shaft driven screw.
Classification by type of intermediate hanging bearings
Rolling hanging shaft trough screw conveyor: Rolling crane bearing adopts 80000 type sealed bearing, which is commonly used to transport materials with a temperature of ≤80°C.
Sliding hanging shaft trough screw conveyor: Sliding crane bearings are equipped with dust-proof sealing devices and are often used to transport materials with relatively high temperatures ≥80°C or materials with large moisture content.
Classification by screw conveyor material
Carbon steel trough screw conveyor: Ordinary carbon steel is mainly suitable for cement, coal, stone, and other industries that have no special requirements for materials.
Stainless steel trough screw conveyor: Stainless steel material is mainly suitable for grain, chemical, food and other industries that have requirements for transportation environment. It has high cleanliness and no pollution, but the cost is high.

Trough screw conveyor is to use the thrust generated by the rotating spiral blade to transport the material to be conveyed. It is usually composed of three parts: the screw conveyor body, the in and out device, and the driving device. The material enters from the feed port of the screw conveyor, and moves in the direction of the discharge port under the rotation of the spiral blade.
Versatility
Can handle a wide range of materials, including powders, granules, and pastes. They can also be used for both dry and wet materials, making them a versatile option for many applications.
Minimal Maintenance
When disassembling the screw, there is no need to move the drive device, and when disassembling the suspension bearing, there is no need to move the screw. The suspension bearing can be lubricated without removing the cover plate.
Customizable

Hygienic
Can be designed to meet hygienic standards for food and pharmaceutical applications. They can be constructed from materials that are easy to clean and sanitize, such as stainless steel.
Space-Saving
It has a compact design and can be installed in tight spaces and can be configured to fit into existing processing lines.
Gentle Handling
Provide a gentle handling of the materials being transported, which is particularly important for fragile materials or those that are easily damaged.
1.Different Types of Screw Conveyor Troughs
The shape of the slot is the first decision a buyer must make.
a."U" - U-shaped screw conveyor troughs are the most common trough shape and are suitable for almost all applications. Remove cover for full access to screws and hangers; makes screw conveyor less time consuming to maintain.
b.Trumpet - The flared screw conveyor chute is used in applications where a large volume of material may be conveyed over the screw or where a larger opening at the top of the chute is required. These applications include fruit and vegetable rendering and agricultural processing centers.
c.Tubular – Tubular screw conveyor troughs are ideal for inclined applications (>15°) as the tube ID is ½" from the auger OD to help prevent material from falling back on the auger as it goes up the slope. Tubular troughs can also be used to convey viscous material because the tight ID/OD minimizes material collection areas.Tubular channels are available as a one-piece "O" or as a two-piece "C" assembly that bolts together.
d.Rectangular – Rectangular screw conveyor troughs are used for grinding applications. The rectangular cross-section allows material to gather around the screw and create a barrier between the screw and the housing. This barrier protects the shell from abrasion.
2. Optional material
Depending on the screw conveyor application, what is being conveyed, and how corrosive or abrasive the material is, the troughs may be made from different materials.
a. Mild Steel (A36) – Mild steel screw conveyor troughs are suitable for almost all conveying applications and are the most commonly used type. Example materials to be conveyed in mild steel screw conveyor troughs include cornmeal, flour, and frac sand.
b. Stainless Steel (304 and 316) - Stainless steel screw conveyors are used in applications where contamination or corrosion is a concern. There is also some thinking that stainless steel is a better choice for abrasive and high impact applications because it will work harden. Example materials conveyed in stainless steel screw conveyor troughs include ice, pet food, salt and spices.
c. Abrasion Resistant Steel (AR235 or AR400) – Abrasion Resistant Steel Screw Conveyor Chutes are suitable for abrasive materials as this material can be 2-4 times harder than mild steel. Example materials to be conveyed in mild steel screw conveyor troughs include foundry sand, potash and minerals.
Depending on the properties of the conveyed material, the tank can be filled at 15%, 30% or 45%.
Specifically, the highest tank fill levels are for light, free-flowing, and non-abrasive particles, and lower tank fill levels (15% and 30%) are more effective for heavier, slower, and more abrasive materials. suitable.
