Screw Conveyor

Product description
Screw conveyors are widely used in various fields such as agriculture, mining, construction, and chemical engineering as material conveying machinery. Their core structure consists of screw blades, a drive shaft, a casing, and a drive unit, capable of conveying bulk materials horizontally, inclinedly, or vertically. They feature a simple structure, small footprint, stable conveying efficiency, and adaptability to various material properties. They are easy to connect with other equipment to form production lines, but their conveying effect is limited for materials with high viscosity or prone to caking.
 
Working principle

The working principle of a screw conveyor is that the driving device drives the transmission shaft and the spiral blades fixed on the shaft to rotate. By utilizing the friction and thrust between the spiral blades and the materials, the bulk materials move forward along the inner wall of the casing as the spiral blades rotate, thus achieving continuous conveying of materials in horizontal, inclined or vertical directions. During this process, the rotation of the spiral blades provides an axial driving force for the materials, enabling them to overcome their own gravity and the friction with the casing and complete the conveying along the set path.

 
Product characteristics

1. Simple and compact structure
It mainly consists of spiral blades, transmission shaft, casing and driving device. It has few components and occupies a small area, making it easy to install in narrow spaces or connect with other equipment (such as crushers, silos).
2. Wide conveying range
It can convey various bulk materials, including powdery (such as flour, cement), granular (such as grains, sand and stones), and small blocky (such as coal blocks, ores), and can achieve horizontal, inclined (with an inclination angle usually ≤ 20°) or vertical conveyance.
3. Conveying process is sealed
The casing can be designed as a fully enclosed structure to reduce dust and leakage of materials, especially suitable for conveying materials that are prone to pollute the environment (such as dust) or are affected by the environment (such as getting damp and deteriorating).
4. Easy operation and maintenance
It operates stably with a low failure rate. Daily maintenance mainly involves lubricating the bearings and checking the wear of the blades. The maintenance cost is low. It can also adjust the conveying volume by controlling the motor speed, which is highly flexible.
5. Can achieve additional functions such as mixing and stirring
When the spiral blades rotate, they can perform light mixing or stirring of the materials, suitable for scenarios that require simple pre-treatment (such as feed mixing, material humidification).
