Claim:
1. A hinge for a particle granulator having a bowl with a lid movable between open and closed positions and having a cylindrical lid collar comprising: first and second spaced apart hinge supports fixed to the bowl adjacent opposite ends of the collar; a pin extending between the hinge supports and through the collar, and having a first end fixed to the first hinge support to preclude rotation of the pin, and a second end extending through the second hinge support; at least one Belleville washer adjacent the second end of the pin to exert a compressive force axially to the hinge supports and collar to create frictional resistance to rotation of the lid; and a nut threaded on the pin adjacent to the Belleville washer to vary the force from the Belleville washer.
