Steel Grizzly Screen

A grizzly screen or deck is a simple way to separate oversized rocks before they are fed into a crushing unit that will be crushed into smaller pieces for further processing. There is a rich history behind grizzly screens, as they were first used a few hundred years ago when mining first became mechanized. Since then, grizzly screens/decks have evolved into essential equipment which enhances the automated refining operation of the modern era. (more…)
