Q: What should I look for in liners? How do I choose the right liner?

A: This has been a frequent question asked of us.
Liners can provide abrasion resistance, corrosion resistance, improved sanitation and clean-out, and improved flowability. Although my answer here will focus on abrasion resistance enhancement in chutes, transitions, spouts, and hoppers, it is important to keep in mind that liner selection will offer inherent differences with regard to the other above parameters.
We all have struggled at times with liner selection, comparing useful life with or without liners to upfront capital cost. The applications for liners are diverse in bulk material handling. Many of the materials handled impose potential severe wear in areas of impact and sliding.

As it applies to these applications, abrasion is the gradual removal of a surface as a result of contact with another material. In the case of liners, this can be imposed by the impact or the sliding of materials such as aggregates or whole grain or by the impact of high-velocity dust particles on the exposed surface. More specifically, this wear can be...Read More>>>
