Small imbalances inside crusher components can lead to substantial, expensive problems if left unchecked. Daily, comprehensive inspections can identify issues such as broken or worn parts, debris build-up and loose components.

Abrasive materials such as aggregates, sand and gravel found in a variety of construction and road building applications, expose crushers to the risk of excessive wear. This wear can cause even greater damage and slower production if not kept in check.

To increase production and efficiency, operators need a strong working knowledge of a crusher’s parameters and should perform regular maintenance and cleaning to reach the crusher’s maximum lifespan.

A crusher’s discharge chute is under a lot of stress for the majority of the machine’s run time, and, as a result, requires regular maintenance. The specialized design uses a shelf system with an abrasion-resistant wear bar that allows crushed material to build up and act as a wear liner. This minimizes maintenance, which translates to dramatic savings in labor and wear parts.

Abrasive materials such as aggregates, sand and gravel found in a variety of construction and road building 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 the crushers' maximum lifespan.

Top Wear Components to Check Regularly

1. 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.

2. 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.

3. 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.

4. 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.
