Keeping your aggregate crusher in top shape isn’t just about extending its lifespan — it’s about boosting productivity, reducing downtime, and saving money. And let’s face it, a crusher that’s running smoothly is a crusher that keeps your team happy. Whether you’re crushing gravel, limestone, or those oddball boulders, following these six essential maintenance tips will keep your crusher in top-notch condition.

Aggregate crushers undergo a lot of wear and tear when crushing rocks. Proper maintenance is important to keep it running smoothly and efficiently. Here are some maintenance tips to keep your crusher in top-notch condition.

1. Inspect and Replacethe Air Filters: Keep Dust Out

Aggregate crushers and dust go hand in hand, but that doesn’t mean your machine has to choke on it. Before operating your aggregate crusher, inspect the air filter. Gently tap or blow out the air filter to remove accumulated dust. When dust exceeds the primary filter, it’s time to change it. A clean filter helps your engine run efficiently and protects it from costly damage. 

2. Check Grease It, Oil It, and Top It Off Fittings and Fluids

Keeping fluids at the proper levels helps your aggregate crusher run properly. Ensure the grease fittings are well-lubricated to prevent friction and wear. Check the oil, coolant, and hydraulic fluid, and top off the fluids if running low. It’s also important to check the fuel and Diesel Exhaust Fluid (DEF) levels to ensure an adequate supply of each. If there’s not, top them off as well. Low fluids can lead to overheating, poor performance, or worse — complete failure mid-job.

3. Maintain the Impact Crusher: A Little TLC Goes a Long Way

Before opening the crusher box, activate the RM release system to allow packed dirt to loosen up. Inspect the impact crusher for wear and damage and replace worn parts. Before closing the crusher housing, clean the edges and seating areas to ensure a proper seal. It’s also essential to readjust the gap size opening and verify that the crusher housing is securely locked.

4. Clean and Clear Your Screens for Better Results

Clean screens allow the crusher to separate materials of different sizes better. For a smooth material bypass, take the time to remove material pegging and blinding on the pre-screen. Check for tears or wear on the screen surfaces and repair or replace as necessary.

5. Inspect and Repair Conveyor Belts

Conveyor belts are the lifeline of your crushers, moving materials efficiently. Keep them in shape by Cchecking the conveyor belts for damage, tears, or worn sections  and repair any issues you find. Adjust belt skirting as needed to prevent material spillage without causing belt wear. Keep belt clips stored with the machine for on-the-spot repairs of minor tears or cut ends.

6. Perform a Complete Visual Inspection

Conducting a comprehensive visual inspection is the final step to ensuring your aggregate crusher is in good condition. Check for damages and missing parts or components. If you find damage, repair it or schedule a service. If you’re missing parts, replace them as soon as possible. Inspect for dust buildup around Rosta torsion elements and clean the area if needed. Look for hydraulic leaks and address them promptly. Finally, check the battery life and charge the remote-control battery if necessary.
