The Model TKK granulator provides ready access to all inner components for servicing. The entire rear quadrant of the crusher frame is hinged, enabling the assembled rotor to be lifted out of the crushing chamber without disturbing any part of the feed system. To save time and effort, this hinged rear quadrant can be supplied with hydraulic openers. For making cage adjustments to accommodate normal wear and to maintain product size, the granulator, in sizes of 44 inches or larger, is supplied with synchronous gear jacks as standard equipment.
