SEDIS – Chains for the Cement Industry

Service environment
Cement plants impose abrasive dust, heat and impact on chains used in feeders, bucket elevators, grate and cooler conveyors.

Construction features

• High‑alloy steels and deep hardening for bearing components exposed to fines and clinker carry‑back.
• Robust attachments and large bearing areas to tolerate shock from lumpy material.
• Sealing and shielding options to block ingress at the joint without trapping heat.

Engineering guidance

• Define MAWL (maximum allowable working load) with factor of safety for transient jams.
• Check pitch choice against minimum sprocket teeth to control polygonal speed fluctuation.
• Specify heat‑resistant lubricants or dry‑film solutions in hot zones; isolate lube lines from radiant heat.

Maintenance cues

• • Trend elongation by section; replace at threshold to protect sprockets.
  • Plan scraper/cleaner interfaces where clinker fines tend to accumulate.
