Question: An operator is feeding a cone crusher and notices the crusher amperage is consistently running high, indicating overfeeding. What is the most appropriate and immediate action?

Answer options: ✅ Reduce the feed rate to the crusher until the amperage returns to the normal operating range.

• Increase the crusher's closed side setting to handle more material.
• Bypass the crusher entirely and send material to a different part of the plant.
• Continue feeding at the current rate, as the crusher will eventually clear itself.

Correct answer: Reduce the feed rate to the crusher until the amperage returns to the normal operating range.

Explanation: Consistently high amperage in a cone crusher indicates an excessive feed rate, which can lead to inefficient crushing, increased wear, and potential damage. Reducing the feed rate is the immediate corrective action.
