Screw conveyors are essential equipment in various industries, facilitating the efficient movement of materials from one point to another. However, the continuous operation of screw conveyors in harsh and abrasive environments can lead to wear and tear, affecting their performance and longevity. To address this issue, manufacturers have developed innovative solutions such as screw conveyor trough wear bars.

AR400 Wear Bars: A Cost-Effective Solution
One of the key materials used in the construction of screw conveyor trough wear bars is AR400 wear bars. AR400 wear bars are known for their durability and resistance to abrasion, making them ideal for use in applications involving abrasive materials such as grit and screenings with high grit content. These wear bars are designed to withstand the harsh conditions within the screw conveyor trough, providing protection against wear and extending the lifespan of the equipment.
Positioning of Wear Bars
In a typical screw conveyor trough, a number of wear bars are positioned longitudinally and at intervals around the inside of the trough. This strategic placement helps distribute the wear evenly across the surface of the trough, reducing the impact of abrasive materials on the conveyor components. By effectively managing the wear and tear on the trough, the wear bars contribute to the overall efficiency and reliability of the screw conveyor system.
Screw Conveyor Trough Lining
Apart from wear bars, another important aspect of enhancing the durability of screw conveyors is the use of trough lining. Trough lining serves as an additional layer of protection for the conveyor trough, shielding it from the abrasive materials being conveyed. Common materials used for trough lining include rubber, polyurethane, and ceramic tiles, each offering unique benefits in terms of wear resistance and impact protection.
Screw Conveyor Liners
In addition to wear bars and trough lining, screw conveyor liners play a crucial role in safeguarding the internal components of the conveyor system. Liners are typically made from wear-resistant materials such as AR400 steel, ceramic, or polyurethane, depending on the specific requirements of the application. These liners help prevent direct contact between the conveyed materials and the conveyor components, reducing friction and wear.
Shaftless Screw Conveyor Material
Shaftless screw conveyors are commonly used in applications where traditional shafted screw conveyors may not be suitable. The absence of a central shaft allows for the conveyance of sticky, viscous, and stringy materials without the risk of clogging. When it comes to selecting materials for shaftless screw conveyors, considerations such as abrasion resistance, corrosion resistance, and impact strength are paramount to ensure long-term performance.
Shaftless Conveyor Liners
Similar to shafted screw conveyors, shaftless screw conveyors also benefit from the use of protective liners to enhance their durability and efficiency. Shaftless conveyor liners are designed to fit the unique geometry of shaftless screws, providing a smooth surface for material flow while minimizing wear and abrasion. These liners are available in various materials and configurations to suit different operating conditions and material characteristics.
