RS 2000 Series Granulators:
The RS 2000 Series granulators can best be summarized as a medium-duty version mid-sized granulators. Most common feedback existing owners comment on is the build quality and heavy duty nature of this series compared to other brands in the same size range.
Common uses for the Getecha RS 2000 Series:
Beside-the-press large part applications (injection molding, blow molding, extrusion)
Central granulating room, off-line applications
Batch feed granulating of small to moderate sized parts
Extrusion application (sheet, profiles, edge trim)
Blow molding applications with special rotor configurations
|
RS 2000 Cutting Chamber/Rotor Technology:
Segmented rotors to provide for most efficient stagger arrangement for your application to save energy, reduce RPM and deliver the best regrind quality.
Staggered rotors for many applications to reduce RPM and noise levels while reducing the required motor size compared to non-staggered rotors.
Fully accessible, tool-free design for safer maintenance and cleaning procedures.
Standard, off-rotor blade setting fixture for quicker and safer blade replacement.
Continuous cutting circle for improved regrind, efficiency and operation of the your granulating needs.

SOLUTIONS TO MEET YOUR NEEDS!
Sample installations:
GRANULATION OF SKELETON SHEET
Duty assigned:
Granulating of skeleton sheet after an Illig-line at a maximum construction height of 34 inches.
- Material PP
- Width of sheet up to 28", thickness of sheet max. 1.5 mm
- Stroke 16 inches
- Throughput up to 450 lb/h with a 6 mm screen
| Granulator:
The granulator is RS 2000 Series w/ 10" rotor diameter.
Technical data:
- Feeding width up to 36 inches
- Cutting circle 10 inches
- Drive capacity 20 HP
- Smooth feeding rollers with frequency converter, Hand-hydraulics for opening of the feeding mechanism
|
 |
Feeding control:
A control jaw could not be inserted as a result of tight space. Two light barriers transmit a signal to the frequency converter when the sheet is too tightly stretched. The feeding process is then switched off.
GRANULATION OF MULTIPLE LAMINATE STRIPS AT DIFFERENT THICKNESSES
Duties assigned:
- Granulating of the marginal strip in the manufacture of laminated floor
- Material: PVC with glass or polyester fibrous web
- B = 50 mm, 0.8 - 4.5 mm strong
- Line speed: 75 ft/min
- Throughput: up to 425 lb/h at 20 mm square holing (coarse crushing)
 |
Special:
Should the thickness of the marginal strips be different, then the thicker marginal strip may press the feeding roller apart in such a way that the thinner marginal strip can no longer be clamped by the roller and will slide out of the infeed mechanism.
To ensure proper operation, it is therefore reasonable to apply one more infeed mechanism. Both infeed devices have a drive-motor and are therefore independent in their speed. The loops of the marginal strips can thereby be compensated in such a way that approximately equal infeed forces brought to bear on both marginal strips.
The fibrous webs tend to get fluffy. Special design on the front sides of the infeed rollers
Set-up of the granulator on a platform, downward drop of coarsely crushed material
|
|
System design:
RS 2004 with two infeed devices (width 70 mm)
Drive capacity 10 HP
Blade made of HSS (64 HRC) for the cutting of the fibrous webs
Speed control of the infeed mechanism:
Potentiometers are mounted on the centre-point of the rotary axis of the control jaw. Angular changes on the control jaw convert the potentiometer/frequency converter to an Off-Set of the infeed speed. By this means, an automatic adjustment to the production machine is realised.
|
 |
GRANULATION OF LONG PROFILES
Duties assigned:
Granulating of profiles with the dimensions 5" X 3" at varying lengths to 16 feet
Moderate throughput capacity
Getecha-solution:
RS 2533 (modified RS 2004), cutting circle Æ 250 mm, 300 mm width of blade
High-type design with bypass hopper
10 HP
Primary hopper infeed for cut-off trim scrap
|
The size of the bypass hopper must be adapted to the cutting circle and the width of the granulator:
Width of the bypass hopper < 80 % of the cutting width radius
The height and the angle of the bypass hopper must be designed in such a way that the profile and the opposite side do not rise up!
Granulator painted per customer specs.
