In industrial equipment, the high discharge end of the shell liner is a key component of many material handling systems, especially in high-wear environments such as ore terminals, mines and quarries. Its main function is to protect the equipment from material impact and wear, while ensuring the smooth flow of materials. This paper will discuss the function, maintenance method and application scenario of high discharge end of shell liner.
1. Function and design
1. Wear resistance and shock absorption
The high discharge end of the shell liner is usually made of high hardness and high toughness materials, such as high chromium cast iron, low carbon alloy steel or ceramic composite materials. These materials not only effectively resist the impact and wear of the material, but also reduce the vibration of the equipment through the damping layer in the design. For example, some new linings use polytetrafluoroethylene (PTFE) and polyurethane (PU) shock-absorbing rubber sheets to further reduce wear on equipment.
2. Optimize material flow
The design of high discharge end can significantly affect the flow efficiency of the material. Reasonable arrangement of lining boards can reduce the accumulation and blockage of materials in the unloading process, so as to improve the operation efficiency of the whole system. ZTA ceramic composite liner, for example, performs well in ore terminal applications because of its smooth, non-stick surface.
2. Maintenance and maintenance
1. Check and replace regularly
Regular inspection of shell liner wear is the key to maintenance. Once the liner is found to be seriously worn, it should be replaced in time to avoid equipment failure caused by liner damage. Some of the new liners are designed with easily replaceable structures, such as single-sided fasteners, greatly reducing maintenance time and costs.
2. Optimize the installation
The correct installation method can extend the service life of the liner. For example, the use of high-strength single-sided fasteners and unique locking mechanisms ensures that the liner maintains its clamping force throughout its wear life. In addition, some liners are designed with sealing plugs to prevent foreign matter from entering the mounting hole, further improving the safety of the liner.
3. Application scenarios
1. Ore dock
Ore wharf is one of the main application scenarios of high discharge end of shell liner. Due to the high hardness of the ore, the large conveying capacity and the high drop impact, the service life of the ordinary liner is often short. Because of its excellent wear resistance and impact resistance, the new ceramic composite liner has been widely used in large ore wharfs such as Rizhao Port and Tangshan Port, and its service life has been significantly extended.
2. Mines and quarries
In mines and quarries, the high discharge end of the shell lining plate is used to protect the discharge end of the crusher, mill and other equipment. By selecting the right liner material and optimizing the design, the wear and maintenance costs of the equipment can be significantly reduced. For example, Metso’s wear-resistant lining solutions provide more durable protection through optimized design and material selection.
Iv. Summary
The high discharge end of shell liner plays an important role in industrial equipment, and its wear resistance, shock absorption and material flow optimization functions are crucial to improve equipment efficiency and reduce maintenance costs. By selecting the right materials, optimizing design and regular maintenance, the service life of the liner can be significantly extended to ensure the efficient operation of the equipment. Whether it is an ore dock or a mine quarry, the high discharge end of the shell liner is a key component to ensure smooth material handling.
