Steel Grizzly
A grizzly is a screen which separates large rocks from fine material by sifting using long beams called grizzly bars.[1]  Grizzlies are usually installed on an incline to take advantage of gravity, but they can also be used horizontally if another way to propel the ore is available. Grizzly bars are placed closest together at the top of the incline, and furthest apart near the bottom. This way the smallest rocks are processed before large rocks, which prevents clogging.[2]
