Screw Conveyor

Product description
Screw conveyor is the key equipment in the industrial material handling process, and is favored by its unique structure and excellent performance. It has a long barrel or trough body, the material is strong, can adapt to all kinds of complex conditions. Inside, the spiral blades are tightly welded to the rotating shaft that runs through the fuselage, like a hovering dragon. Blades or continuous equal pitch, to achieve smooth and efficient transportation; Or use variable pitch design to flexibly respond to different material characteristics.
 
Working principle
Power transmission: The screw conveyor is powered by a motor, and the motor is connected to the screw shaft by a coupling, a reducer and other transmission devices. After the motor starts, the power is transmitted to the spiral shaft, so that the spiral shaft rotates at a certain speed.
Material push: A spiral blade is installed on the spiral shaft. When the spiral shaft rotates, the spiral blade also rotates. After the material enters the chute from the feed port, it will be driven by the spiral blade. Because the spiral blade has a certain pitch and spiral Angle, in the rotation process, it will produce a component force along the spiral axis of the material, which will push the material to move along the axis in the material groove, as the nut rotates on the screw, and the final material is discharged from the discharge port.
Material conveying speed: The conveying speed of the material is related to the speed of the spiral shaft, the pitch of the spiral blade and the characteristics of the material. In general, the faster the spiral shaft speed and the larger the pitch, the faster the material delivery speed. However, for materials with different characteristics, such as materials with large viscosity or poor fluidity, the speed and pitch need to be properly adjusted to ensure that the material can be smoothly transported.
 
Features & Benefits
1. Simple structure: mainly composed of spiral shaft, spiral blade, chute, drive device and other components, compact structure, easy to manufacture and install, occupy small space, can be operated in narrow space.

2. High conveying efficiency: the rotation of the spiral blade drives the material to move continuously and stably along the axis, which can achieve higher conveying capacity and meet the needs of different production scales.

3. Flexible conveying direction: horizontal, inclined or vertical conveying can be achieved. By changing the installation Angle and blade design of the screw conveyor, it can adapt to a variety of different production layout and process requirements.

4. Good sealing: the material tank is usually closed, which can effectively prevent material leakage and dust flying, not only ensure the integrity of the material, but also improve the working environment, suitable for conveying powder-like, granular and other dust prone materials.

5. Strong adaptability: can transport a variety of types of materials, including grain, fertilizer, cement, ore, etc., the particle size of the material, humidity has a certain range of adaptation, according to the characteristics of the material to choose the appropriate spiral blade and transport parameters.

6. Low maintenance cost: fewer parts, stable operation, low probability of failure, daily maintenance is mainly to check the wear of spiral blades and bearings, timely replacement and lubrication, simple maintenance work, low cost.

7. Multi-point feeding and discharging can be realized: multiple feeding and discharging ports are opened on the tank to facilitate the addition and extraction of materials at different locations, which can meet the complex production process requirements and improve the flexibility and convenience of production.
