In an increasingly competitive marketplace, modern farming relies more and more on efficient material handling to keep productivity high, costs controlled and workflows running smoothly. From grain and livestock feed to fertiliser, seeds and agricultural waste, moving granular materials safely and consistently is vital in the day-to-day operations of your farm.
In this guide, from the conveyor experts at Coveya, we’ll explain in detail how screw conveyors in agriculture are used across the agri sector, their many benefits and the different types of screw conveyors available. We’ll also help you choose the right system for your needs and determine whether agricultural screw conveyors could help improve efficiency on your farm.
Quick Recap: What Are Screw Conveyors?
In short, a screw conveyor is essentially a material handling system that uses a rotating helical screw, often known as a flight, to move granular and loose materials through a tube or trough. They are very effective at transporting powders, pellets, grains and other granular materials in a controlled, consistent and efficient way.
Unlike some conveyor systems, screw conveyors significantly reduce spillage and loss as they tend to use either a trough or a completely sealed tube to transport the material through, which also helps control dust. For a deeper explanation, we’ve prepared a full guide to the different types of screw conveyors.
Why Efficient Material Handling Matters on Modern Farms
Like many businesses, modern farms are under significant pressure to do more with less. Labour shortages across the sector are making it difficult to recruit and retain workers, particularly for repetitive material handling tasks. Meanwhile, rising fuel, equipment and operational costs continue to eat away at profits.
While facing these difficult issues, farmers must continue to harvest and process their produce more quickly to maximise productivity and prevent delays down a very tightly controlled supply chain. It may only be one small part of the overall picture, but this is where screw conveyors in agriculture can play their part.
Automating the movement of grain, feed, fertiliser and other bulk materials can make oft-repeated processes much more efficient and consistent. They can also help lessen product loss through spillage and maintain the quality of products throughout the handling process.
Common Agricultural Applications of Screw Conveyors
Grain Handling
One of the single most common uses of screw conveyors in agriculture is grain handling. They can be used to efficiently transport wheat, corn, barley, rice and soybeans between different areas of your farm or processing facility. Screw conveyors are regularly used for loading and unloading storage bins, as well as moving grain between cleaning, drying and processing stages, helping to maintain a steady and controlled flow of materials.
Feed Handling
Your livestock operations can often be boosted and streamlined by clever use of screw conveyors to transport animal feed quickly and consistently. They’re versatile enough to be integrated into automated feeding systems, helping reduce the need for manual handling while ensuring your animals always receive a consistent supply of feed. Screw conveyors are also commonly used within feed mills, helping move ingredients and finished feed products between different stages of production.
Seed Processing
Seed quality and careful handling are critical for your agricultural operations, so controlled automatic handling is always an important consideration. Screw conveyors can meet the requirements needed to gently but efficiently move seeds between processing, packaging and storage areas while maintaining a consistent flow. When correctly specified, this type of farm conveyor helps reduce unnecessary handling, boosting seed quality and helping operators manage a significant volume of seeds more efficiently throughout each cycle.
Fertiliser Handling
When fertiliser needs to be moved in bulk, it can be difficult to do so safely and efficiently without the ideal equipment. Screw conveyors deliver a controlled way to transfer material, allowing fertiliser to be moved between storage, mixing and application areas with the utmost care and minimal spillage. By reducing the need for manual handling in this area, they can also contribute to workplace safety while creating a more consistent and efficient process.
Biomass and Agricultural Waste
Screw conveyors can also be used efficiently in a range of biomass and agricultural waste processes, especially where materials need to be moved in a contained and controlled manner. Their versatility allows them to handle wood chips, crop residues and various forms of organic waste, helping speed up your waste management operations. Their enclosed design also helps reduce material loss while maintaining a cleaner and safer working environment.
Key Benefits of Screw Conveyors on Farms
1. Reduced Labour Requirements
Efficient screw conveyors can help you reduce reliance on manual labour or redeploy workers in more essential areas across your farm. This can help you save time and money, and can be especially beneficial on farms that have been hit by the general labour shortage across the agriculture sector.
2. Increased Operational Efficiency
Because screw conveyors provide a continuous flow of material, they help streamline day-to-day operations. Faster movement of materials between storage, processing and loading areas reduces delays and bottlenecks, helping keep materials moving consistently throughout your farm and improving overall productivity.
3. Space-Saving Design
The popularity of screw conveyors in agricultural settings is boosted by their relatively compact footprint compared to other solutions, and our expert engineers can even install them in areas where space is limited. Their flexible, modular design also means they can be integrated into existing layouts with minimal disruption.
4. Versatility Across Materials
One of the biggest advantages of farm conveyors is their sheer versatility. They can be used to move a wide range of agricultural materials, including grain, feed, seed, fertiliser, powders and pellets. Our conveyors are built to handle a wide range of materials, as you can discover on our Materials We Handle page.
5. Lower Product Loss
The enclosed design of many screw conveyors helps minimise spillage during the transport of materials, which can really help reduce loss and wastage. This can help protect valuable and hazardous materials while also creating a cleaner working environment and a more efficient overall process.
6. Improved Workplace Safety
By reducing manual lifting and limiting direct contact with moving materials, screw conveyors can help improve workplace health and safety. Our enclosed systems help to reduce exposure to dust and moving machinery, helping create a safer environment for farm workers.
Types of Screw Conveyors Used in Agriculture
Horizontal Screw Conveyors
Horizontal screw conveyors, as the name suggests, move materials across a level plane and are commonly used for short to medium-distance transport on farms. They can be used to transfer grain, feed and other bulk materials between storage areas, processing facilities and other parts of your farm as necessary, providing a simple and reliable solution.
Inclined Screw Conveyors
Inclined screw conveyors are used when materials need to be moved from one elevation to another. In agriculture, they are commonly used for loading silos, storage bins and processing equipment, helping move grain, feed and fertiliser efficiently while making better use of the available space on your farm.
Shaftless Screw Conveyors
Shaftless screw conveyors are cleverly designed to handle materials that may cause blockages in more conventional conveyor solutions. Their design helps reduce clogging when moving sticky, fibrous or difficult agricultural by-products, making them particularly practical for biomass and waste-handling applications.
Tubular Screw Conveyors
Tubular screw conveyors use a fully enclosed casing which helps contain dust, reduce spillage and protect sensitive materials from contamination. This makes them particularly useful where product quality is important or where materials are stored and transported outdoors in changing conditions.
