Machine Checklist for Rock Crusher

During the inspection of a used rock crusher we check those items and write an inspection report

• Basic Machine information and configuration
• Engine information and condition
• Condition of Exterior (chassis, sheet metal, conveyor belts and frames)
• Condition of hydraulic system (hoses, valves, cylinders, vibrators, motors)
• Functional test as far as possible
• Wear of Jaw or Impact crusher (also possible for cone crusher)
• Condition of the Feeder, Hoper, Bunker
• Test of forward/reverse operation
• Functional check of Safety items
• Comments and recommendation for repairs
• Transport dimensions

See a sample of a report below. On request we can send a PDF-version of such a report.

Pictures and video coming with a Mevas-Report

Each machine inspection comes along with 50-80 pictures and in some cases with a short video. In case of interest it is possible to see an inspection report for an impact crusher in detail on our Google-Drive folder.

Checklist for crusher inspections

When inspecting and comparing impact crushers and jaw crushers, there are some specific points to consider for each type of crusher. Here’s a checklist highlighting the key differences for both types of machines.

Take a close look at the following points during an inspection of a pre-owned impact crusher:

1. Exterior: Check for visible wear, rust or damages.
2. Structure: Inspect the frame for any damage or structural issues.
3. Rotor and Crushing Chamber: Examine the rotor, hammers and crushing chamber for wear.
4. Bearings: Check bearings for wear and proper lubrication.
5. Feed System: Inspect the feed hopper and conveyor for damage.
6. Drive System: Examine the motor, gearbox and drive belts for wear and alignment.
7. Hydraulic System: Check hydraulic hoses and cylinders for leaks.
8. Electrical Components: Ensure all electrical components are working.
9. Safety Features: Check the guards and the emergency stop functionality.
10. Documentation/Testing: Review maintenance records, user manuals, and conduct a test run (if possible with material).

And here is the checklist for the inspection of jaw crushers:

1. Jaw Plates: Examine the jaw plates for wear and assess the need for replacements.
2. Bearings: Inspect bearings for wear or play.
3. Toggle Plate and Toggle Seat: Check for wear and proper alignment.
4. Eccentric Shaft: Inspect for damage or misalignment.
5. Flywheel: Examine for balance and signs of wear.
6. Hydraulics: Check for leaks, proper pressure and functionality.
7. Drive System: Inspect the motor, belts, and pulleys for wear, alignment, and tension.
8. Clearance and Adjustment: Confirm settings and test adjustment mechanisms for smooth operation.
9. Electric: Check the electrical system, including wiring, switches and control panels.
10. Safety items: Verify the presence and functionality of safety features such as guards and emergency stops.
11. Functional test: Carry out a function test. If possible, use some material to check how the machine works.

What is a rock crusher and what is it used for?

1. Mining: In mining operations, crushers are used to break down the extracted ore or minerals into smaller, more manageable pieces. This makes it easier to transport and process the materials further.
2. Construction: Rock crushers are employed in construction projects for breaking down large rocks into smaller, more manageable sizes for use in construction materials like concrete, asphalt, and other building materials.
3. Quarrying: In the quarrying industry, crushers are used to break down the extracted rock into smaller pieces that can be used for various construction purposes. This includes aggregates used in concrete production.
4. Recycling: Crushers are often used in recycling operations to break down materials such as concrete, asphalt, and other construction waste into reusable materials.
5. Demolition: In demolition projects, rock crushers are used to break down structures and buildings by crushing the concrete and other materials.
