1. A Used Crusher That Has Been Freshly Painted

A coat of paint can cover a lot of sins. While a refurbished machine with documented service history is a safe option, a used crusher that has been quickly painted may be hiding wear and tear. Be cautious of what’s often called an “aerosol overhaul.” Always ask for service records, details of refurbishment, and a clear explanation of what has been replaced or repaired.

2. The “You Can Crush Anything” Claim

No crusher can process everything. Each type of crusher—jaw or impact—has limits. If a salesperson insists that a machine can crush any material without exception, it’s a red flag. This often signals a lack of technical knowledge or, worse, a deliberate exaggeration. A trustworthy supplier will help you match the right crusher to the right material and application.

3. Unrealistic Production Rates

If production claims sound too good to be true, they probably are. Output depends on a variety of factors:

• Feed size and preparation
• Material hardness (e.g., asphalt vs. reinforced concrete)
• Moisture content
• Loading equipment capacity
• Operator skill and experience

While past case studies can give a good indication, no one can guarantee specific production numbers for your site. Always treat “maximum output” figures with caution and ask for realistic performance ranges instead.

4. Sales Without Site Evaluation

A compact crusher is not a “one size fits all” purchase. If a supplier pushes a machine without understanding your application—through a site visit, material analysis, or detailed consultation—that’s a warning sign. The right crusher should be chosen for your specific material and output requirements, not simply because it’s available in stock or at a lower price.

5. Limited Access to Spare Parts and Service

No matter where you operate, equipment uptime is critical. A supplier who cannot provide quick access to wear parts and after-sales service puts your business at risk. Ask about local or regional spare part availability, service networks, and response times. If a manufacturer has no infrastructure in your region, your downtime could be costly.

6. A “Good Used” Crusher at a Bargain Price

If a used compact crusher is priced well below market average, there’s usually a reason. Crushers are high-wear machines—over time they require replacement parts and significant maintenance. A machine priced at the low end often signals heavy use and upcoming repair costs. A fair price reflects remaining life hours and condition; a bargain price often signals future headaches.

7. No Start-Up Training Included

A crusher is only as productive as its operator. If a supplier doesn’t include operator training, it’s a red flag that they may not fully understand the machine themselves—or don’t prioritize your success. Proper training ensures safe operation, optimized production, and reduced downtime. Make sure training and ongoing support are part of the purchase.
