Introduction
Powder screw conveyor is a type of conveyor system specifically designed for handling and transporting powdered materials. It consists of a helical screw blade contained within a tube or trough, which rotates to move powders along the conveyor length.
Powder screw conveyors are widely used in industries such as food processing, pharmaceuticals, chemicals, plastics, building materials, agriculture, mining and environmental engineering. They are used to transport and handle powder and granular materials, including food raw materials, pharmaceutical powders, chemicals, plastic granules, cement, ore and waste treatment. These conveyors provide reliable material handling solutions, increasing production efficiency and material handling accuracy.
Types of powder screw conveyor
1. According to material:
Stainless steel: It is mostly used in industries with high requirements for hygienic environment, such as food and medicine. It is acid-resistant, corrosion-resistant, wear-resistant, not easy to rust, and easy to clean after use. Its service life is longer than that of carbon steel.
Carbon steel: Used in industries that do not have very strict hygiene requirements. It has lower cost, large transportation capacity, good heat insulation effect, no need for cooling devices, and low power consumption. However, the anti-corrosion and anti-rust effects are somewhat inferior.
2. According to the conveying angle:
Horizontal: used for continuous and even transportation of loose materials horizontally or slightly inclined (below 20º). The transportation distance is generally not more than 20 meters.
Incline: used to convey materials within a 60° range, with a conveying length of up to 60 meters.
Vertical: Conveys materials vertically upward at 90°. The rotation speed is higher than that of ordinary screw conveyors. The lifting height is generally not more than 3 meters.
Application
Powder screw conveyors are widely used in many different industries, including but not limited to the following areas:
1. Food processing industry: Powder screw conveyors are often used in the food processing industry to transport powdery food raw materials such as flour, sugar powder, seasonings, and cereals.
2. Chemical industry: In the chemical production process, powder screw conveyors are often used to transport chemicals, granular raw materials, powder particles and other materials.
3. Pharmaceutical industry: used to transport pharmaceutical raw materials, pharmaceutical powders, capsule fillings and other powder materials in the pharmaceutical process.
4. Building materials industry: Powder screw conveyors can be used to transport powder or granular materials such as cement, lime powder and other building materials.
5. Agricultural field: In agricultural production, powder screw conveyors can be used to transport powdered agricultural raw materials such as feed, seeds, and fertilizers.
6. Plastic processing industry: used to transport plastic raw materials such as plastic particles and plastic powder.
7. Mining industry: In the process of ore processing and ore transportation, powder screw conveyors can be used to transport ore powder, slag and other materials.

Features and Benefits
1. Reliability: Blocking and jamming are not easy to occur during material transportation, and the feeding is uniform and stable.
2. Flexibility: The powder screw conveyor can adapt to different process requirements and material characteristics. By adjusting the diameter, pitch and speed of the spiral, accurate control and regulation of materials can be achieved. Additionally, they can be customized based on site conditions to accommodate different installation and layout needs.
3. Efficiency: The powder screw conveyor can achieve continuous and uniform material transportation. The rotational motion of the screw propels material along the length of the conveyor, enabling efficient material transfer. They are often able to handle large volumes of material and maintain low energy consumption during processing.
4. Versatility: The powder screw conveyor can not only carry out horizontal transportation, but also can carry out inclined and vertical transportation. This makes them suitable for a variety of different process layouts and space constraints.
5. No dust: It has good sealing effect, prevents dust and pollution, can isolate materials with strong odor and easily raise dust, and improve the working environment.

Special design
Composition Structure
The main structure of the powder screw conveyor includes the following parts:
Screw: It is usually a spiral screw made of wear-resistant material (such as stainless steel or carbon steel). The screw is fixed to the shaft and an electric motor drives the rotation of the shaft, thereby propelling the material along the length of the conveyor.
Tube/Trough: The spiral is located in the tube or trough body. They are usually made of wear-resistant, corrosion-resistant materials such as stainless steel or carbon steel. Pipes or troughs play the role of containing and protecting materials, and also provide the support needed for materials during transportation.
Inlet and Outlet: The powder screw conveyor has an inlet and an outlet. The inlet is used for inputting materials, and the outlet is used for discharging materials. The location and shape of these ports can be designed and customized based on specific application needs.
Drive System: It usually consists of a motor, reducer and coupling or belt drive. The motor provides power, and the reducer converts the high-speed rotation of the motor into a rotational speed suitable for the screw conveyor, and transmits the power to the screw through a coupling or belt.
Support Structure: Powder screw conveyors are usually installed on a support structure to provide stable support and fixation.
