Screw Feeder vs Screw Conveyor


Function –

Screw Feeders precisely regulate the flow rate of material into a process or system. They ensure that the material is delivered at a consistent and controlled rate. 

Screw Conveyors are designed to transport material from one location to another within a plant or system, ensuring efficient and reliable movement within the operational environment.

Application –

Screw Feeders are used for precise metering and dispensing of materials and are commonly utilised in applications where accurate dosing and feeding of material is critical such as in chemical processing, food production and pharmaceutical manufacturing. 

Screw Conveyors are ideal for moving large quantities of material efficiently over both short and long distances within a facility, often integrated into larger material handling systems in industries like food, agriculture and chemical. 

Placement in Process –

Screw Feeders are typically at the start of a process, under storage units such as bins or hoppers to manage the initial flow of materials.

Screw Conveyors can be placed at any point within a process where material needs to be transported, facilitating the movement and adding of material throughout the system.


Screw Feeders provide precise control of material flow rate, ensuring consistent and accurate dosing for processes that require exact quantities.

Screw Conveyors are capable of not only transporting material but also performing functions such as mixing and handling various types of materials, from free-flowing to more challenging substances.


Screw feeders are meticulously designed to control the flow rate of materials into a process or system. They regulate the amount of material being fed, ensuring a consistent, measured supply. This precision makes screw feeders ideal for applications requiring exact handling, such as packaging or batching. Typically positioned at the beginning of a process, under bins, hoppers, or silos, screw feeders manage the flow of materials into the next stage. Unlike conveyors, they do not transport materials over long distances but instead focus on controlling the rate at which materials enter subsequent equipment. This capability is vital in processes where precise metering or dispensing is required to maintain product quality and operational efficiency.

A screw conveyor is a highly versatile piece of equipment used for transporting bulk materials from one point to another within a plant or system. Capable of conveying materials horizontally, vertically, or on an incline, screw conveyors can be placed at any point within a process where material needs to be moved from one location to another, making screw conveyors particularly popular across many industries. Screw conveyors consist of a rotating screw or auger housed within a trough or tube, which propels materials along the conveyor path by either pushing or pulling them. Screw conveyors are renowned for their efficiency, reliability, and ability to manage a wide array of materials, from free-flowing powders to sluggish, non-free-flowing materials, making them indispensable in diverse industrial applications.

Recognising the distinctions between screw feeders and screw conveyors is crucial for selecting the appropriate equipment for your specific material handling needs. Each type of equipment offers unique advantages tailored to different applications, ensuring that your material handling processes are efficient and effective.


Versatility – Screw conveyors are exceptionally versatile, capable of transporting materials in various orientations. They can move materials horizontally across long distances, vertically to higher elevations, or at an incline to fit specific plant configurations. This adaptability makes them suitable for diverse applications across multiple industries.

Efficiency – Screw conveyors greatly improve bulk handling processes by automating material transportation. This automation reduces the need for manual labor and decreases the time needed to move large quantities of product, resulting in faster and more efficient production cycles. Their continuous movement ensures a steady flow of materials, enhancing overall operational efficiency.

Flexibility – Screw conveyors provide versatility in both plant layout and design. They can be tailored with multiple inlets and outlet points, enabling them to serve diverse locations throughout a facility. This adaptability ensures efficient routing of materials to various processing or storage areas, thereby optimising workflow and effectively managing resource allocation.

Material Handling – Screw conveyors excel in managing a diverse array of materials, including fine powders, sluggish substances, and those with intricate or irregular shapes. Their ability to handle challenging materials, which might otherwise clog or disrupt other conveyor types, can be enhanced by removing the central pipe. This adaptability makes screw conveyors particularly suited for industries working with a wide variety of unconventional materials.

Space Utilisation – Screw conveyors can be customised to integrate seamlessly into your plant layout, effectively utilising available space. They offer flexibility in terms of length, diameter, and configuration options, allowing them to be tailored to specific operational requirements. By integrating screw conveyors into the plant design, you can maximise space utilisation and streamline production processes.

Maintenance – Screw conveyors are engineered with maintenance considerations, often featuring drop bottoms and self-cleaning functionalities. Drop bottoms facilitate the effortless removal of residual materials, thereby simplifying the cleaning procedure. Self-cleaning mechanisms contribute to sustained operational efficiency by minimising downtime and preventing the accumulation of debris and obstructions within the conveyor system.


Accuracy in Feed Rate – Screw feeders enable meticulous control over the flow rate of materials, which is essential for processes that demand exact quantities. This accuracy ensures that each batch receives the correct amount of material, reducing variability and enhancing product consistency.

Adjustability – Operators can easily adjust the feed rate to meet specific production requirements. This flexibility is vital for processes where the material flow needs to be varied based on production speed, product type, or other factors.

Materials handling – Screw feeders can handle a broad spectrum of materials, including fine powders, grains, granular, flakes, and pellets. This versatility makes them suitable for industries ranging from food and pharmaceuticals to chemicals and plastics.

Efficient Material Use – Precise control over material flow minimises the risk of overdosing or underdosing, which can result in product loss and waste. Accurate metering ensures the optimal use of raw materials, leading to significant cost savings and promoting a more sustainable operation. By reducing material waste, screw feeders enhance both economic and environmental efficiency in your production processes.

Hygienic options – Screw feeders can be manufactured in an array of finishes, including crevice-free with smooth, easy-to-clean surfaces and components for industries like food processing, chemical and pharmaceutical to minimise the risk of contamination and to help maintain a sanitary environment, ensuring that product quality and safety are consistently upheld. 

Ease of Maintenance – Many screw feeders feature a design that facilitates quick and efficient maintenance. Accessible components and modular construction allow maintenance personnel to swiftly inspect, clean, or replace parts without extensive downtime. Quick-release mechanisms for critical components further expedite maintenance tasks, ensuring minimal disruption to production schedules.
