Aggregates Wear Parts
Equipment, Parts and Materials by Production Process

Aggregate operations handle large volumes and measure margins per tonne. Wear-part selection must address:

Sustained production and low downtime; particle shape, flakiness, elongation, grading and fines content; the impact, abrasion and polishing characteristics of each rock; slurry erosion and dewatering-screen blinding in wet processing; rebar, wood, asphalt and tramp material in recycled feed; and strict iron contamination, particle-size and turbidity limits for specialty sands.

The longest-lasting wear part is not necessarily the best choice. Changes to chamber geometry, rotor profile or VSI discharge velocity can reduce product quality and overall plant returns.
