Granulator for blow moulding

The following technical features in particular ensure the high efficiency of the grinding process for blow molding applications:

  • a super tangential inlet into the cutting chamber, simplifies and speeds up the feeding and catching of voluminious plastic parts
  • the segment rotor with its staggered blade rows
  • fans in the hopper for additional air flow during the grinding process and therefore improved cooling of the regrind

The powerful RS 2400 and RS 3000 central granulators in the B-design are very well suited for inline use close to production due to their compact design and comprehensive sound insulation.

The model series RS 38000, RS 45000 and RS 6000 easily swallow voluminous plastic parts even with their standard cutting housing.

We are looking forward to assist you on the choice of machine!


High efficiency

  • opening of hopper and cutting chamber without tools
  • screen holder removable
  • low cleaning time due to smooth, all-side machined surfaces
  • high energy efficiency due to cutting geometry and EnergySave motor controller

Excellent regrind quality

  • scissors cut with constant cutting circle
  • rotor in v-cut keeps the material in the centre
  • stationary blade is mounted against hardened stop
  • rotary blades adjustable outside of the granulator

High realibilty

  • strong construction
  • rotor shaft made of high-quality tempered steel
  • rotor segments mounted om shaft with couplings (over 20 years experience)
  • solid belt pulley for a high centrifugal moment

Individual features

  • water cooled cutting chamber for temperatur-sensitive material
  • wear protected version for filled materials
  • various hopper versions
  • mechanical and electrical integration into a production line

Various rotor versions, drives and blade qualities are individually designed for your application, grinding reliably, energy-saving and producing an optimum grinding material quality.

Suitable wear protection packages secure your investment, reduce your maintenance costs and increase your profit when grinding abrasive materials.

Water-cooled cutting chambers and cooling-air supply reduce the thermal stress on your materials, protect against plastification in the cutting chamber and enable optimum grinding even in critical applications.

Maximum energy efficiency thanks to the latest design, drive motors in the energy efficiency class up to IE 4 and the use of GETECHA EnergySave, a system that significantly reduces your power consumption under partial load.

Electrical accessories from GETECHA connect your rotary cutter to the peripherals, control upstream and downstream units, create safety and increase your productivity. If you need special equipment and cannot find it anywhere, please contact us.

The modular granulator platform of the GETECHA rotary cutter allows variations of a wide range of proven assemblies, components and functions from the entire GETECHA rotary cutter range.

Perfect dosing and material feed into the rotary cutter as well as material discharge are options which are decisive for grinding performance and regrind quality. GETECHA peripherals (belt conveyor, screw feeders, metal detectors, ionizers, screw dischargers and extraction systems…) optimize your grinding system and create efficiency and safety.

RS 2404-B

The RS 2404-B central granulator is the compact size reduction solution for volumnious residues or faulty parts from blow moulding production.

RS 38060

The central granulator of the RS 38000 series proves its worth in blow moulding technology as a stand-alone or inline solution, depending on the on-site situation.

Hopper with push-in device

For the photo the fly-back curtains in the hopper have been removed. In the upper area the air cooling fans and the push-in device can be seen clearly.

RS 6012

Lagre granulator of the RS 6000 series in a sound-insulated cabinet for the size reduction of blow-moulded fuel tanks. The feeding conveyor belt serves for additional cooling of the tanks.
