Screw conveyor liner is an important part of screw conveyor, and its selection and use have an important impact on the performance and service life of the equipment. When selecting a liner, it is necessary to consider comprehensively according to the characteristics of the conveyed object and the process requirements to select the appropriate liner material and specifications. At the same time, during use, it is also necessary to pay attention to the installation and maintenance of the liner to ensure its normal operation and prolong its service life. 
The function of the screw conveyor liner is mainly to protect the spiral blades and cylinders, reduce wear and corrosion, and also improve the conveying capacity and efficiency of the equipment. There are many kinds of materials for liners, such as polymer materials, wear-resistant ceramics, rubber, etc. Different materials have different abrasion, corrosion and impact resistance, so the selection should be evaluated according to the actual needs. In addition, the installation and fixing method of the liner also needs to be determined according to the design and process requirements of the equipment to ensure its stability and reliability. During the operation of the screw conveyor, the liner will be subjected to the friction and impact of the material, so it needs to be inspected and repaired regularly. If the lining is found to be seriously worn or cracked, it should be replaced in time. At the same time, it is also necessary to regularly clean up the residual materials inside the equipment to prevent the accumulation of materials from causing damage to the equipment. In order to prolong the service life of the liner, some preventive measures can also be taken, such as controlling the particle size and humidity of the material, reducing the speed of the equipment, etc. 
In conclusion, the selection and use of screw conveyor liners has an important impact on the performance and service life of the equipment. In the process of selection and use, a variety of factors should be considered to ensure the normal operation of the equipment and prolong the service life. At the same time, it is also necessary to pay attention to the maintenance and maintenance of the equipment, and find and solve problems in time to keep the equipment in good condition.
