The replacement cycle for cone crusher wearing parts, like the mantle and concave (bowl liner), isn’t fixed but typically ranges from a few weeks to several months. A general guideline for a cone crusher’s eccentric sleeve and bushings is replacement every 1000-2000 hours of operation, while the thrust bearing might last 1500-3000 hours.
The actual lifespan is heavily influenced by several key factors, so it’s crucial to monitor wear closely rather than sticking to a rigid schedule.
Key Factors Influencing Wear Part Life
The wear life is a direct result of the interplay between the material being crushed and how the crusher is operated.
1. Material Characteristics (The Most Important Factor)
Abrasiveness: This is the single biggest factor. Materials with high silica (SiO₂) content, like granite, quartzite, and abrasive river rock, will wear out liners extremely fast. Soft materials like limestone or coal will result in a very long wear life.
Hardness: While related to abrasiveness, a very hard but non-abrasive material might be difficult to crush but won’t necessarily wear liners quickly.
Feed Size: Feeding material that is too large (slab-shaped or oversized) for the crushing chamber can cause localized “point loading” and stress, leading to premature cracking and uneven wear.
Contaminants: The presence of uncrushable “tramp” metal (rebar, bucket teeth, etc.) can cause catastrophic failure instantly. High clay content can pack in the chamber, leading to high pressure and accelerated wear.
