Side mills

GRS 180 / GRS 300

It grinds sprues of all kinds and small missing parts economically and quietly. The large grinding chamber opening in combination with the inclined rotor makes the size reduction of bulky sprues possible. The GRS RotorCutters can be individually equipped and adapted. Both models are available with a low or high frame. Different rotors or drive powers can also be easily realised.

The GRS 180 / GRS 300 side grinders are the perfect choice for those looking for a quiet and efficient way to grind sprues of all kinds. The large grinding chamber opening in combination with the inclined rotor enables the grinding of even bulky sprues. The GRS RotorCutters can be individually adapted to the respective tasks. The GRS 180 / GRS 300 are powerful, reliable and long-lasting side mills. Their grist quality is excellent, as the grist is ground evenly and effectively. Both mills are easy to clean. The DIN ISO 13849-1 Performance Level C safety technology starts when the hopper is full. The rotor has double bearings on one side. In addition, the mills operate very quietly and have a high productivity.
 

RS 1615

The RS 1615 can be individually equipped with hopper and material container depending on the task. Its knives are always ready for use, because after a knife change or regrinding, the cutting gap and the cutting circle always remain identical without any adjustment work. Almost maintenance-free and easy to clean, the RS1615 requires very little floor space in the area of the injection moulding machine. It reliably grinds sprues and small missing parts and offers a good quality of the material to be ground and the optimum feed behaviour over the entire service life of the knives.
 
The highly productive RS 1615 impresses with optimal accessibility and short maintenance or cleaning times. The completely swing-out grinding chamber allows easy access to all parts of the mill, the sieve can be removed without tools. The rotating front disc seals the bearing against dust. The rotor has double bearings on one side and is very reliable. The blades, arranged in a scissor cut, deliver excellent grist quality. The RS 1615 side mill is available in various hopper or container versions and can be individually adapted to the respective requirements.

The compact RS 2400 is designed for hourly throughputs of up to 220 kg and can be used close to production. It has a cutting circle of 240 mm and is built in cutting widths of 226, 452, 678 and 904 mm.
It is used as a small central mill in injection moulding operations or as an auxiliary mill for large sprues, as well as a feeding machine for edge strips, foils, punched grids and profiles.
 
GETECHA's RS 2400 is renowned for its high energy efficiency and excellent regrind quality. Its constant rotor cutting circle shear cut technology and EnergySave motor controller make it energy efficient. The knives can be adjusted outside the RotorCutter, the adjustment gauge is included. The grinding chamber and hopper can be opened without tools, the sieve holders are removable, and smooth surfaces enable quick cleaning. The rotor blades are mounted on a steel shaft with clamping sets. The solid V-belt pulley has a high moment of inertia to move even heavy loads. An optionally cooled housing protects temperature-sensitive material. If required, the RS 2400 can be supplied in a wear-protected version for filled materials. In addition, different hopper variants can be selected.
 

RS 30000

The segmented rotor is the perfect solution for fast and uncomplicated cutting. It performs its task reliably and powerfully - whether in injection moulding or on the blow moulding machine. Depending on the model, the ergonomic RotorCutters process up to 600 kg/h. The RS 3000 series has a cutting circle of 300 mm and is manufactured in cutting widths of 400, 630, 945, 1,260 and 1,575 mm. The RS 3000 series is particularly versatile - whether as a central granulator in injection moulding operations, as an auxiliary or central granulator in blow moulding operations (canisters up to 20 l) or as a feeding machine for edge strips, foils, punched grids and profiles.
 
The RS 3000 is very productive. The hopper and grinding chamber can be opened without tools, and the sieve holders are removable. Its smooth surfaces are quickly cleaned. The cutting geometry and the EnergySave motor controller enable high energy efficiency. The regrind quality is very convincing due to the shear cut with constant rotor cutting circles. The V-cut rotor holds the material in the centre, while the fixed knives are mounted against the hardened stop. In addition, the rotor blade can be adjusted outside the rotor cutter.
 
The RS 3000 is very reliable. Thanks to the solid housing construction and the high-quality steel rotor shaft, it is very stable. The rotor segments are mounted on the steel shaft with clamping sets, and the V-belt pulley generates a high inertia. If required, it has a cooled housing for temperature-sensitive material. The rotor and hopper variants can be selected depending on the application.

Large mills

RS 6000

This central mill was designed for all areas of plastics size reduction. It quickly and carefully shreds large-format parts from the injection moulding and blow moulding sector such as punching grid rolls, solid sheets, bumpers, thick-walled pipes and extruder lumps. The cutting circle of the RS 6000 series is 600 mm, its cutting widths 600, 900, 1,200 and 1,500 mm. The machine serves as a central mill for bumpers, dashboards, punching grid rolls, extruder lumps, pipes and sheets, as well as for large parts such as barrels or plastic tanks. In recycling, it processes up to three tonnes of plastics, copper or circuit boards per hour.
 
Their easy handling is one of the advantages of the series. The hopper and grinding chamber can be opened without tools. The sieve holder can be rolled out and the smooth, continuously machined surfaces are quickly cleaned. The cutting geometry and EnergySave motor controller ensure impressive energy efficiency. The V-cut rotor fixes the cut material in the centre of the rotor, the fixed knives are mounted against hardened stops, and the rotor knives can be adjusted outside the RotorCutter.

Feed mills

RotorCutter with wide infeed

The extremely quiet RotorCutter offers a continuous and adapted film feed. The range of applications is wide: The machine serves as a central mill and shreds film rolls from the winder stand (off-line) or works directly behind a thermoforming line (in-line). In a low-built version, they stand under a die cutter. The infeed rollers are smooth (standard), knurled or toothed, as required. In addition, with larger roller diameters, articles that are not punched out can also be shredded in the film. GETECHA developed an automatic speed adjustment system especially for use behind a thermoforming machine. This evaluates the dancer movement and position and determines the current average feed speed of the thermoforming machine. The result is transmitted to the infeed of the rotor cutter. The adjustment of the speeds with a potentiometer is therefore no longer necessary. This allows the person at the machine to focus on optimising the production of parts.
 
The dancer is pneumatically damped, keeps the film taut and prevents undue tension. Adjustment to the line speed is made by the frequency-controlled infeed. The adjustable wipers avoid wrappers. Users benefit from integrated sound insulation and the decoupling of the shredding unit from the base frame. The low rotor speed reduces the dust content in the ground material and also lowers noise emissions.
 
Further advantages: The funnel and grinding chamber can be opened without tools. The sieve holder can be rolled out and the smooth, continuously machined surfaces are quickly cleaned. The cutting geometry and EnergySave motor controller ensure impressive energy efficiency. The V-cut rotor fixes the cut material in the centre of the rotor, the fixed knives are mounted against hardened stops, and the rotor knives can be adjusted outside the RotorCutter. The rotor segments are mounted on the steel shaft with clamping sets, the V-belt pulley generates a high inertia torque. If required, it has a cooled housing for temperature-sensitive material. The rotor and hopper variants can be selected depending on the application.
 

RotorCutter for edge trim

To dispose of edge trims on calenders and rewinders, GETECHA can equip its RotorCutters with two infeeds. Adjusting to the speed of the upstream line enables production-safe operation. The infeed rollers are smooth (standard), knurled or grooved as required and are all wear-protected. For applications with highly fluctuating or high line speeds, GETECHA integrates the infeed speed with the line speed. The additional speed adjustment enables production-safe operation.
 
Further plus points: The hopper and grinding chamber can be opened without tools, and the sieve holder can be removed. Smooth, fully treated surfaces allow for quick cleaning. Cutting geometry and EnergySave motor controller ensure impressive energy efficiency. The shear cuts have a constant rotor cutting circle. The fixed knives are mounted against hardened stops, the rotor knives can be adjusted outside the RotorCutter.
The encapsulated design and low speed have two advantages: quiet operation and low-dust regrind.
 

Pre-shredder

Foil cutter FS

The machine shreds edge strips directly in the pipeline - even very thin films (up to 10 µm). Besides plastic, it processes many other materials: paper, cardboard, aluminium, textiles, glass fibre fleece and even wood veneer.
The FS is designed for installation in pipelines. Its stable cast housing as well as the bearing of the rotor on both sides ensure an accurate cutting gap.

The film cutters are used on production lines from 20 to 1,000 m/min. Its drive motor can be adapted to the respective line speed by means of a frequency converter. In addition, different rotor variants extend the range of application to the shredding of chips.
 

Hacker GH

The GETECHA chippers cut sheet edge strips directly during production in the extrusion line. They are mounted on an adjustment unit below the sheet run. One chipper works per edge strip. The cuttings fall onto a cross conveyor belt which transports them sideways out of the line. The adjustment unit can be adapted to the respective production machine, covering the complete production width. The length of the precut parts depends on the line speed of the extrusion line and the number of strokes of the chippers. The number of strokes of the chippers can be adjusted to the line speed with the frequency converter.
