How to get maximum life out of pulleys
One of the most impactful practices aggregate producers can employ to save money for their plant is carrying out proper care and maintenance of equipment, to extend the unit’s lifespan. By conducting regular inspections and following appropriate maintenance instructions, producers can avoid costly replacements.
Most pulleys provide for more than 10-20 years fatigue life if designed properly – as long as wear items, such as lagging and bearings, are maintained. It is more cost effective, in most cases, to refurbish an existing pulley than to buy a new one. Therefore, pulleys should be reworked to save cost and get maximum life out of the machine.
Conveyor pulley lagging should be replaced before any indications of bare steel. If the steel shell is compromised, a new pulley is often required. Therefore, producers should take appropriate steps to inspect and rework pulleys to ensure the pulley is not damaged beyond repair.
Precision Pulley & Idler offers two levels of rework service
PPI (Precision Pulley & Idler) offers customers several means to maintain the condition of its pulleys. In addition to providing a lagging wear strip to help customers identify when the lagging is ready to be replaced, PPI offers two levels of rework service: Tier I and Tier II.
TIER I
Tier I is a basic strip and relag for a conveyor pulley. This level of rework is for pulleys that do not require any disassembly or re-assembly. PPI offers three procedures for this level of rework: stripping, re-lagging and non-destructive testing. The pulley is typically received completely disassembled.
