How to increase impact crusher output

Increasing the output (measured in tons per hour, or TPH) of an impact crusher involves a holistic approach that combines operational adjustments, strategic maintenance, and optimizing the entire crushing circuit.Increasing the output of an impact crusher involves optimizing several key factors, from the material feed to the crusher’s internal settings and regular maintenance.

1. Optimize Material Feed:

Consistent and Uniform Feed: This is paramount. An erratic or inconsistent feed rate can lead to underloading or overloading, both of which reduce efficiency.

Underfeeding: The crusher is not working at its full potential, leading to wasted energy and reduced throughput.

Overfeeding: Can cause clogging, increased wear on components, higher power consumption, and poor product shape.

Solution: Use a vibrating feeder or grizzly feeder to ensure a steady, even flow of material across the full width of the rotor. Adjust the feeder speed to match the crusher’s capacity.

Optimal Feed Size:

Larger Feed Size: Can slow down processing and increase wear. Ensure the maximum feed size is within the crusher’s recommended limits (typically 80% of the feed opening depth).

Solution: Pre-screening is crucial. Use screens to remove oversized material before it enters the crusher, which can overload the machine and increase wear.
