Caring for your cone crusher: A guide to optimising performance
A cone crusher punishes itself in every minute of operation. It squeezes a dense mass between heavy castings until the mass disintegrates. It abrades and minces aggregate until the material yields to the applied forces. It rumbles and vibrates and bangs as its core shaft spins eccentrically to capture and reduce chunks of aggregate.
P&Q University Lesson 8- Screening | #Site Title
At the primary stage, large scalping screens remove fine material before the feed enters the primary crusher, helping to protect the crusher's wear parts from abrasive stone or sand material that has already been sized. Without scalping, the primary crusher's liners wear faster, requiring more frequent changes and maintenance downtime.
