A screw conveyor is a machine that uses a motor to drive a spiral to rotate and move materials to achieve transportation purposes. It can be transported horizontally, tilted or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, and convenient closed transportation.

In terms of transportation form, screw conveyors are divided into two types: shaft screw conveyors and shaftless screw conveyors. In appearance, they are divided into U-shaped screw conveyors and tubular screw conveyors. It has compact structure, small cross-sectional area, light weight, good sealing performance, high conveying efficiency and flexible process layout. It is easy to assemble, disassemble, move and operate. It is suitable for transporting a variety of powdery, granular and small bulk materials, such as clay powder, coal powder, cement, sand, grains, small coal, pebbles and cast iron chips. It is not suitable for conveying materials that are highly viscous, easy to agglomerate, and easy to deteriorate.

The spiral is the main component of the machine. It consists of a shaft and spiral blades welded on the shaft.

The wear is serious when transporting hard materials, such as iron ore, quartz stone, etc.

In order to ensure the long-term stable use of the screw conveyor, a layer of wear-resistant ceramic lining plates will be installed on the spiral blades of the conveyor and inside the box.

The material of the wear-resistant ceramic lining plate is alumina ceramic. Has good wear resistance, corrosion resistance and high temperature resistance.

The application advantages of industrial wear-resistant alumina ceramics in conveyors are reflected in the following aspects:

Wear resistance: Wear-resistant ceramics can significantly extend the service life of equipment with their excellent wear resistance. In mining operations, the feeder needs to continuously handle a large amount of hard materials such as ore, sand and gravel. These materials will cause serious wear and tear on the inner wall of the feeder during the transportation process. The high wear resistance of wear-resistant ceramics can effectively reduce this wear and reduce maintenance frequency and costs.

Corrosion resistance: Materials may contain corrosive ingredients. Wear-resistant ceramics have good corrosion resistance and can resist the erosion of these corrosive substances, protect the metal structure of the feeder from corrosion, and ensure the long-term stable operation of the equipment.

High temperature resistance: Due to the high-speed friction and compression of materials, higher temperatures may occur. Wear-resistant ceramics have excellent high-temperature resistance and can maintain stable performance in high-temperature environments to avoid equipment failure or performance degradation caused by high temperatures.

Improve conveying efficiency: The smooth surface of wear-resistant ceramics can reduce the resistance of materials during the feeding process, allowing materials to pass through the feeder more smoothly, thus improving conveying efficiency.
