Dual
Stage Granulators - DSC- 18
The patented* Model
DSC-18 Dual State Granulator offers an improved, high output first
cutting stage, plus modular flexibility to meet a wide range of
processing applications.
You can use Foremost's standard HD-5B Granulator for a second stage;
or replace it with any model you choose. The DSC-18 uses two separate
cutting chambers. The first has a solid cylindrical rotor embedded
with 18 disc-shaped cutters which shave off small sections or pieces
of the solid lumps loaded in the hopper. The greater the weight
of purgings on this rotor, the higher its output.
The
shavings fall down into a conventional two-bladed open rotor lower
cutting chamber (Model HD-5B Granulator)
with sizing screen, where they are further reduced to the desired
size granulate.
*Patent Numbers 4,164,329 and 3,378,210
The standard configuration has a 16" x 20" lower chamber and 5/16"
hole size screen. This combination can achieve 1,000 to 2,000 lbs.
per hour on polyethylene and polystyrene purgings. Over-all throughputs
are generally constrained by the capability of the lower stage selected.
The upper stage, operating alone as a pre-cutter, has produced 10,000
lbs. per hour of cuttings from polyethylene "logs", for example.
With
that factor in mind, the machine was designed in a modular fashion
so that the upper stage can be coupled with a variety of lower stages;
be set up to feed several conventional granulators; or operate as
a separate pre-cutter. In all instances, blower unloading is standard
due to the high volume of output.
The DSC-18 upper stage uses unique disc-type cutters. Their concave
"cutting circle" has been optimized through extensive engineering
analysis to achieve maximum output at the lowest power requirement.
Since just one quarter of each disc is used for cutting at any time,
a new keen surface can be easily revolved into place simply by loosening
a single hold-down bolt on each disc when it dulls. In this way,
four fresh surfaces are available on each cutter before the disc
must be removed for resharpening. And since the knives rest in machined
seats in the upper chamber rotor, no gap settings are ever required.
Knife access is obtained by pivoting the hopper to one side.


The upper chamber is mounted on a wheel and rail system and can
be readily rolled back to expose the lower cutting chamber for service
or cleaning. The standard Model HD-5B
Granulator has a solid ribbed rotor. Screen access is via a
hinged rear panel, which also allows the blower chute to be removed.
The exact configuration of your machine can be varied to meet your
particular requirements.
