These Grizzly Feeders have vibrating body that is made of thick plate along with a lining of anti-abrasive plate inside. These Grizzly Feeders increase the durability of the wear-prone crushing elements by maximizing the feeding area. Heavy Duty Grizzly Feeders are installed at the opening or over the hopper to prevent the damage to the crushing equipment and the hopper.
