Screw Conveyor

Product description
U-shaped screw feeder is widely used in industry, and its structure includes U-shaped groove, spiral shaft, spiral blade, drive device and inlet and outlet. The groove body is made of high quality steel plate, and the drive device includes motor and reducer. When working, the motor is driven by the reducer to rotate the spiral shaft, and the material enters from the feed port. Under the axial thrust of the spiral blade, it moves upward along the U-shaped slot to the discharge port to complete the feeding. Its compact structure covers a small area, sealing cover plate with U-shaped design, anti-leakage and dust effect is good, suitable for high health requirements of the industry. And the transmission efficiency can be adjusted according to the characteristics and needs of the material, the main parts are easy to replace, easy to maintain, can transport powder, granular, small block and other materials, a wide range of application.

Working principle
The working principle of U-type screw feeder is based on mechanical transmission and screw propulsion mechanism. The motor in the driving device is energized and the high-speed rotating power generated is transmitted to the reducer. The reducer converts the high speed and low torque of the motor output into the low speed and high torque suitable for the work of the spiral shaft.

The rotating spiral shaft drives the spiral blade to rotate synchronously, and the material falls into the U-shaped groove from the feed port. When the spiral blade rotates, its surface exerts normal thrust on the material, and this force is decomposed into the component force along the spiral axis and perpendicular to the axis. The vertical component makes the material rotate around the axis, but the U-shaped groove wall limits this rotation. The axial component force pushes the material to overcome the friction with the groove wall and itself, and moves upward along the U-shaped groove until it reaches the discharge port, realizing the continuous conveying of the material from the low to the high.

Product characteristics
U-type screw feeding machine has many advantages, and it has obvious advantages in industrial production. From the structural design point of view, it is compact in structure, occupies small space, and can flexibly adapt to all kinds of factory layout, whether it is an old workshop with limited space, or a new factory in pursuit of efficient space utilization, it can be easily installed.

In terms of material transportation, the U-shaped tank body is equipped with a sealed cover plate, which has excellent sealing performance, can prevent material leakage, effectively inhibit dust flying, and greatly improve the working environment, especially for industries with harsh sanitary conditions such as food and medicine. Moreover, its conveying efficiency is quite high, and it can flexibly adjust the shape, size and speed of the spiral blade according to the characteristics of the material, such as particle size, humidity, viscosity, etc., and accurately match the conveying needs to achieve efficient feeding.

From the maintenance point of view, the equipment structure is relatively simple, the main components are clear and easy to disassemble and replace, and the daily maintenance work is easy, which can greatly reduce the maintenance cost and downtime, and ensure the continuity of production. At the same time, its scope of application is extremely wide, powdery flour, cement, granular feed, grains, small chunks of ore and other materials, it can be stably transported, strong material adaptability, so that it in the chemical industry, building materials, food processing and many other industries to show their skills.
