2-3 Typical Features and Components
Hopper
The hopper is an upright enclosure bolted to the top of the cutting chamber. The hopper is
designed to facilitate the feeding of material to the rotary knives and to protect the operator
from material that may be thrown out.
Cutting Chamber
The cutting chamber is a rectangular enclosure comprised 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. The
downstroke bed knife shield is adjustable.
The screen is supported in position 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 rotor carries the rotor knives. The rotation of the rotor produces a cutting action between
the rotor knives and the stationary bed knives, thus reducing the material size.
Drive System
The rotor is indirectly driven by the motor through v-belts. The motor shaft pulley, v-belts,
and the rotor shaft pulley are shielded by safety guards or a sound enclosure.
The motor is mounted on an adjustable sliding base, which is mounted at the left end of the
granulator.
Discharge System
The granulated material that falls through the screen is collected by a discharge chute beneath
the cutting chamber and directed into a bin. The bin can be removed from the front of the
granulator for emptying.
On models fitted with an airveying system (optional), the granulated material that has fallen
through the screen is collected in a transition piece located beneath the cutting chamber. The
transition piece is connected to a blower, which conveys the granulated material through
ducting to the cyclone separator. The cyclone separator allows the granulated material to drop
out of the air system into a container.
Base
The base is caster-mounted, with two swivel casters for easy positioning.
