Commitment:
Screw feeder conveyor is a mechanical conveying system that uses a rotating screw to move material from one point to another and is the choice of users who require particularly efficient discharge/feed from silos or hoppers. Screw feeder conveyor is designed to measure and control the flow of materials entering the process, such as mixing or mixing operations. It can be customized according to user requirements with different diameters, different lengths, and different inclination angles. It can be equipped with a speed-regulating motor to continuously adjust the speed to achieve quantitative feeding.
There are several types of screw feeder conveyor available, each designed for specific applications. Here are some of the most common types:
1. Horizontal Screw Feeder Conveyor: This type of screw conveyor is designed to transport bulk materials horizontally from one point to another. It is commonly used for material handling applications in industries such as food processing, chemical processing, and agriculture.
2. Vertical Screw Feeder Conveyor: This type of screw conveyor is designed to transport bulk materials vertically, often used to elevate materials from one level to another. It is commonly used in industries such as construction, mining, and agriculture.
3. Inclined Screw Feeder Conveyor: This type of screw conveyor is designed to transport bulk materials at an incline, often used to move materials between floors or up an incline. It is commonly used in industries such as food processing, chemical processing, and pharmaceuticals.
4.Twin screw feeder conveyor: Consists of two parallel, counter-rotating screws. This design allows for higher material throughput and greater mixing capacity than single screw conveyors. Twin screw feed conveyors are commonly used in industries such as food processing, chemical processing and pharmaceuticals.
5.Volumetric screw feeder conveyor: This type of screw feeder is designed to deliver a fixed volume of material per unit of time. It is commonly used in applications where precise dosing of material is required, such as in the food and pharmaceutical industries.
6. Shaftless screw feeder conveyor: This type of screw conveyor has no central shaft, which allows it to handle material that would otherwise wrap around a conventional screw. It is commonly used for handling materials such as sludge, gravel, and other abrasive or sticky materials.
Screw feeder conveyors are used to transport and handle bulk materials in a wide range of industrial applications. Some common uses for screw-fed conveyors include:
1. Metering and batching: It is commonly used in the metering and batching of materials in many industries such as food processing, chemical processing and pharmaceuticals. They can be designed to provide precise flow or material volume, making them suitable for applications where accurate metering is critical.
2. Mixing and stirring: It can be used for mixing and stirring powdery, granular, pasty and other materials. They can be designed with different types of screws, such as helical, ribbon or paddle, to achieve the desired mixing characteristics.
3. Conveying and conveying: It is often used for conveying and conveying materials between different stages of the production process. They can be used to move material horizontally, vertically or obliquely, making them suitable for a wide range of applications.
4. Filling and packaging: It can be used to fill and package materials such as powder and granules into bags, containers or other packaging forms. They can be engineered to deliver precise quantities of material, making them suitable for applications where precise filling is critical.
5. Garbage disposal: It can be used for the disposal and transportation of garbage materials, such as sludge, gravel and other sundries. They can be designed to handle abrasive and corrosive materials, making them suitable for use in wastewater treatment, mining and other industries.
Screw feeder conveyor is mainly composed of feed port, spiral blade, cylinder, hopper, drive device, discharge port and other parts. During operation, after the material is conveyed to the housing of the screw feeder through the feed port, the material is subjected to the centrifugal force and the frictional force of the pipe wall in the internal spiral groove, and rotates with the spiral blades, and moves along the spiral under the action of gravity. The trough slides downwards, so that the material is continuously pushed forward and conveyed, and evenly discharged from the discharge port.

Screw feeders and screw conveyors are two different types of mechanical conveying systems that serve different purposes. Screw feeders are designed for precise metering of materials into a process, while screw conveyors are designed for moving materials from one point to another over longer distances or elevated heights. Here are some other key differences between screw feeders and screw conveyors:
| Comparison item | Screw Feeder | Screw Conveyor |
 |
 |
|
| Speed | 5-20 RPM | 100-600RPM |
| Capacity | Used to process relatively small volumes of material, typically a few grams to a few pounds per minute. | Larger volumes can be handled, ranging from a few hundred pounds to several tons per hour. |
| Design | There are shorter screw lengths and larger diameters for better control of material flow. | Available in longer screw lengths and smaller diameters to maximize material throughput. |
| Application | Typically used in applications where precise metering of materials is critical, such as in the food and pharmaceutical industries. | For applications where material needs to be transported over longer distances or heights, such as in the mining and construction industries. |
| Material handling | It is designed for processing materials that are relatively easy to handle, such as powder, granular, flake, etc. | Can handle a wider range of materials, including abrasive and corrosive materials. |
Screw feeder conveyors can be customized to meet specific requirements and to suit the material being conveyed. Here are some examples of custom types of screw feed conveyors:
Shaftless Screw Conveyor: This type of screw conveyor has no central shaft, making it easier to clean and maintain. It is often used to move sticky or viscous materials that can clog conventional screw conveyors.
Live Bottom Screw Conveyor: This type of screw conveyor is used to convey difficult materials such as wet or sticky materials. It features a series of independently moving blades to prevent materials from sticking together or clumping.
Twin-Screw Feed Conveyor: This type of screw conveyor has two screws that rotate in opposite directions for better control of the flow of material. It is typically used in applications requiring consistent and precise flow.
Flexible Screw Conveyor: This type of screw conveyor has a flexible tube that can be bent and twisted to fit the available space. It is ideal for use in tight spaces and complex production layouts.

Silo, hopper emptying screw conveyor
Screw feeders placed below silos, hoppers, or other containment systems are used to control the discharge of bulk solids (in powder or granular form) from these units and from feeding equipment such as conveyors, mixers, etc.
Dust removal system, bag filter
Dust collectors, filters, and jet pulse filters are used to collect dust generated in the production line. The screw conveyor installed under the dust removal system is used to unload the collected dust.
Mixing, batching, batching system
Screw feeder conveyors can be used to control the discharge of bulk solids. Volumetric measurement of powdered and granular bulk materials is possible by controlling the shaft speed of the screw feeder. Gravity feeding of mixers or containers is accomplished by measuring the weight of the product being processed.
Bulk solid handling equipment uses screw conveyor for feeding/discharging
In some industrial processes, bulk solids processing equipment can be fed or unloaded with the help of screw conveyors. Feeding, batching, mixing, crushing processes are some examples where screw conveyors are used.
