Functional Description
2-1 Models Covered in This Manual
This manual provides the necessary instructions for the installation, set-up, and
maintenance of our 3200 Series 32” x 63” and 32” x 84” granulators, which include models
BPHD, GPH and MSH.
2-2 General Description
The 3200 Series Granulators have a common cutting diameter of 18.1” (460 mm) and a
common throat size of 18” by widths of 40” or 56”. They are designed for big jobs in
reclamation of bulky blow-molded parts, pipe, purgings, sheet, film, fibers, and other high-
torque applications.
The machines conform to ANSI Standards B151.11 and NFPA 70, and they can be fitted with
screens having hole sizes to suit the particular application.
2-3 Typical Features and Components
Hopper
The hopper is a hinged, upright, enclosure with sound dampening. It tilts completely out of
the way for unobstructed access to the cutting chamber. It is designed to facilitate feeding
of material to the rotary knives and to prevent chips thrown from the cutting chamber from
reaching the operator.
Cutting Chamber
The cutting chamber is a rectangular enclosure comprising the main frame, the bed knives,
the bed knife shields, a balanced rotor, and a screen.
The main frame of the cutting chamber carries the bed knives and the bed knife shields.
Both the bed knives and shield are adjustable, and the bed knives have reversible cutting
edges for extended life.
The internal surfaces of the solid steel cutting chamber are machined to an exceptionally
smooth finish for ease of clean-out.
The screen is mounted in a swing-down cradle, positioned just below the rotor and acts as a
separating barrier to the granulated material, retaining the material in the cutting chamber
until the particle size is such that it will pass through the screen holes.
The solid hardened rotor carries the rotary knives. High-strength alloy steel screws are used
for attachment of all knives.
