Rotary drum liners are a valuable tool in protecting the drum shell in applications where excessive corrosion or abrasion is a concern. This is typically seen in the heap leaching process, as well as in inorganic fertilizer production.
Liners can also provide a temporary solution to maintaining production when shell wear is present, while a replacement shell is made.
Available Liners
FEECO provides both rubber and metal drum liners. Metal liners are available in stainless steel for corrosion resistance, or AR steel for abrasion resistance.
All drum sizes can be outfitted with a liner.
Indications that a Drum Liner may Require Replacement
A worn liner can allow material to get between the drum shell and liner, causing shell wear. Liners not regularly monitored and replaced have the potential to cause catastrophic shell failure.
As such, liners should be regularly monitored as part of an inspection program, with personnel looking for the presence of:
- Thin spots
- Holes
- Visible wear
Any signs of wear should be addressed immediately.
Frequently Asked Questions (FAQs)
Drum liners require replacement only when they become worn. The frequency of replacement varies significantly from one operation to the next, with the material being processed and operating conditions making wear rate unique in each setting.
Liners are generally available with a lead time of 6 to 12 weeks.
Since the drum will be shut down during installation of the new liner, and the interior will be readily accessible, it’s a good opportunity to conduct any other necessary repairs, drum service work, or inspections.
