Solutions for Inline Recycling 2Cy^ars ZERMA Shanghai ■ ±5S The Home of Size Reduction

ZERMA offers a suitable solution for any challenge in the field of plastic recycling. For the inline recycling sector ZERMA offers the following machine series: GSL Slow Speed Granulators to directly grind runners and sprues from the injection machine GST Soundproofed granulators featuring a very aggressive tangential infeed and cutting chamber GSC Soundproofed compact granulators suited for a wide variety of inline tasks GSE Same as GSC series, but without soundproofed housing All machines offer these benefits: • Consistent end product • Reduced fine particles • Low heat generation • Reduced...

Take control of your scrap Granulation and size reduction of plastics, e.g. scrap from blow and injection moulding or extrusion processes, requires a lot of know how and experience. ZERMA has a long history in the design and implementation of size reduction equipment and offers a product portfolio which is as wide as the spectrum of materials that need to be processed.

Inline recycling application examples GSL slow speed granulator working next to an injection moulding machine, directly grinding runners and rejects. The regrind is directly reintroduced into the production. ZERMA granulators can be integrated into a variety of production processes. Common applications include rejects and scrap from injection moulding of small parts like caps and closures to TVs or automotive components as well as flush from blow moulding applications. With an optional roller feeder the machines can be used for the inline processing of edge trim and skeletal waste in extrusion...

GST granulator in a blow moulding application. Tops and tails are fed to the granulator by a conveyor and the resulting material is directly fed back into the extruder. GSC granulator grinding skeletal waste in a thermoforming process. The machine is equipped with a dual feed hopper in order to accept reject products. Advanced engineering – great results 05

The right machine for today‘s inline recycling requirements The ZERMA granulators of the GSL, GST and GSC series are designed for the inline recycling of scrap like runners, sprues, tops, tails and reject parts directly at the production machine. The resulting regrind can either be collected in a central silo or be mixed with virgin material and reused immediately. The compact size and low noise of these machines makes them a perfect fit for in-house applications. Machines can be integrated into the production line Low dust and noise emission yy Simple maintenance and up to date safety yy Different...

ZERMA range of inline granulators 07

GST series- aggressive tangential infeed The ZERMA granulators of the GST series are available in two rotor diameters, 250 and 400 mm with widths ranging from 300 to 1000 mm. While the smaller machines feature an open F rotor, the bigger machines rely on a heavier S rotor. The rigid design makes them dependable units and includes advanced standard features such as replaceable wear plates. • Compact design • Soundproofed chamber and hopper • Aggressive infeed and curved back wall • Large screen area • Knives are adjusted outside the machine

Small footprint – great results 09

GSC series – the soundproofed all-rounder The ZERMA GSC compact/soundproof granulators are designed with a complete soundproof enclosure resulting in an extremely quiet operation. Different rotor designs are available in widths ranging from 300 to 1400 mm with a diameter ranging from 300 to 700 mm. The completely welded cutting chamber in conjunction with the V rotor GSC design ensures dependability in operation and universal application use. While it delivers excellent soundproofing capabilities, it still offers easy and quick access to the cutting chamber during rotor and stator knife changes,...

Sturdy compact design Different rotor types available yy Soundproofed housing yy Knives are adjusted outside of the machine yy Integrated controls yy GSC – with optional feeding conveyor Efficient cut – great results 1

GSL series – dependable low speed performance The beside the press granulators of the ZERMA GSL series run at low speed to ensure low noise operation and low dust regrind. The specially designed rotor knives can be sharpened numerous times and due to their unique design do not need to be adjusted. The granulators are fed via a sound absorbing hopper which can be tailored to fit your specific needs. All GSL machines offer connections for vacuum systems in order to directly reintroduce the regrind into your production process. GSL – with optional conveyor belt and integrated metal detector

• Direct drive • Specially designed rotor knives do not need to be adjusted in the machine • Easy tool less access to the machine for maintenance and cleaning • Frame and hopper can be tailored to fit your needs

The disc pulverizers of the PM series are available with disc diameter from 300 to 800 mm. These pulverizers are high speed, precision grinders for the processing of medium hard, impact resistant and friable materials. The material to be pulverized is introduced through the centre of a vertically fixed grinding disc which is mounted concentrically with an identical high speed rotating disc. Centrifugal force carries the material through the grinding area and the resulting powder is collected with a blower and cyclone system. Depending on the application the machines can be equipped with one piece...

Simple adjustment of cutting gap Choice of discs or segments Low drive power - High throughput Innovative efficient design Wide range of accessories Easy temperature control High speed – great results 15

Technical details – well thought out and efficient GSL: The curvature of the specially profiled rotor knives ensures a constant cutting radius after re-sharpening thus maintaining the original cutting gap. Awkward knife adjustment is no longer necessary. The Quick Snap System allows the lower front plate section to be easily removed for granulator cleaning. The lower front plate section is held in position by two sturdy lever clamps. Staggered rotor blades create an The granulators are available with individual blade cut thus increasing different rotor options to fit diffethe cutting torque....
