What matters in the process
Wear can occur at feed acceleration zones, scroll surfaces, screens and discharge areas, depending on the design. Corrosion and abrasion can occur together, so choosing a material on corrosion resistance alone may be insufficient. Wear protection also affects inspection, replacement access and spare-part planning. The dry-solids load and its variation are essential for assessing both process and mechanical duty.
A practical example
A short trial may demonstrate clarification but reveal little about long-term wear. Combine trial performance with a review of the wear locations, protection method, inspection plan and expected replaceable components. Do not convert an unverified lifetime estimate into a fixed operating-cost guarantee.
What to check or specify
- Provide mineralogy, hardness and particle distribution.
- State normal and maximum dry-solids loading.
- Identify corrosive liquid constituents and temperature.
- Review wear protection, inspection access and repair methods.
Turn the result into a decision
Ask for a component-level wear strategy and a spare-parts proposal alongside the separation result. Compare LW, LLW or a combined family only where its mechanism matches the material. Include the cost and downtime of maintaining the wear-protected parts in the lifecycle assessment.
