Abstract
A hinge dampening device is provided for a granulation processor having a bowl and a lid. A dampening device includes first and second spaced apart hinge supports fixed to the bowl and a pin extending through the lid collar residing between the hinge supports. The first end of the pin is fixed to the first hinge support, and a second end of the pin extends through the second hinge support. An adjustable compressive force is applied axially to the hinge supports and lid collar to create frictional resistance to rotation of the lid. The rotational resistance provides controlled opening and closing of the lid.

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 being fixed to one or the hinge supports to preclude rotation of the pin;
- and
- a compressive force being applied axially to the hinge supports and collar to create frictional resistance to rotation of the lid.
A processor for granulating particulate material, comprising:
- a bowl for mixing the material;
- a lid hinged to the bowl for movement between open and closed positions, and having a hinge collar;
- a hinge pin extending through the hinge collar of the lid and having opposite ends;
- a pair of spaced apart hinge supports mounted on the bowl and receiving the ends of the pin;
- one end of the pin being fixed to one of the hinge supports to preclude pin rotation;
- a nut on the opposite end of the pin and being threadable in opposite directions to increase and decrease pressure on the collar to adjust rotational resistance of the lid between the open and closed positions.
