Greater crusher life with four-check process

Hard abrasive materials, such as granite, ores and rock found in many mining applications, expose crushers to the risk of excessive wear. This wear can cause even greater damage to the machine if not kept in check. Damaged components slow production processes and result in additional expenses and downtime. Complete regular maintenance and cleaning to reach crushers’ maximum lifespan.

Top Wear Components to Check Regularly

  • Blow Bars: As a fundamental element in the crushing process, blow bars come in contact with abrasive material at great speed and force when moving materials. These parts require daily inspections and, if worn or damaged, replacement.
  • Curtain Anvils: Like blow bars, curtain anvils also come in contact with and take the impact of abrasive material while crushing the moving material. For optimal performance, inspect daily and replace if worn or damaged.
  • Screen Cloth: Screen cloth sorts and separates crushed material. Examine the screen cloth for left behind debris and to prevent potential screening problems clean the screening cloth by hand.
  • Belts: Belts take on the impact of the crushed material while moving it. Check conveyors for loose, punctured or broken belts. If damaged, make the proper adjustments or repairs.

Overall Maintenance Strategies

Small imbalances inside crusher components can lead to substantial, expensive problems. Daily, comprehensive inspections identify issues such as broken or worn parts, debris build-up and loose components. Keep units serviced, making sure wear parts remain properly secured.

A well-maintained crusher leads to several more years of service and more profit when it comes time to resell.
