How to choose the correct pebble crusher for your site

Oct 23, 2019 Robustness of the crusher: Pebble crushing is the toughest of crushing applications, so a crusher needs to be robust. Our Trio® TC series cone crusher is typically 40-50% heavier than similarly sized machines in the market and provides a superior level of protection against fatigue. When pebble crushing, weight really does matter.
