Conair’s SG2 Smart Granulator control adds predictive maintenance to larger Viper models
tum is used for the discharge, since the material is pre-accelerated for the later air conveyance. The modification helps to raise throughput rates, while energy consumption is unchanged. Design and ergonomics were also important factors in the redesign. The standard machine extensions – such as vibro-feeder or mounting bracket for the vacuum feeder – blend into one compact machine concept with clear lines. Mean- while, all parts are easily accessible. Even the door lock has been optimised, and now operates more efficiently and with less space requirements. Cables, connections and sensors are gathered in a central processing unit. Control unit of water injection – through valves and sensors – is now placed in an accessible housing that is dust- and splash-proof.
Hellweg’s 300 series central grinders combine a compact design with high performance. Thanks to the sturdy machine housing and the high moment of inertia of the massive, solid rotor they enable powerful grinding of a variety of parts, including pipes and profiles, thick-walled mouldings and – when using the special BR rotor – single-stage shredding of solid lumps from production start-ups. The MDSi 600/300 Smart Control Plus version includes power consumption analysis to optimise economy and automated lubrication with Blue- tooth monitoring to minimise maintenance effort. Each system features Hellweg’s own digital Smart
Control System which captures parameters such as power consumption, motor speed and bearing temperatures, as well as blade, screen and V-belt status. Because the control system can continuously optimise the relationship between motor load and throughput, it ensures economical operation while requiring little input from operators. Smart Control is generally available for all models and sizes of Hellweg system, starting from the 150 series machine-side grinders for granulat- ing small parts and sprues up to the 600 series heavy duty grinders designed for the toughest applications.
Redesigned pulveriser Neue Herbold has renewed its ZM 800 Pulverizer with a number of new features. One is the stream technique optimisation of the machinery housing. In the past, machines of this type were made with a round housing on a platform – but the new housing passage is supplied in a curved design. The background for the modification is that the material’s angular momen-

Size reduction Weima presented a number of systems – including granulators and shredders – at this year’s NPE show in the US. Its size reduction machinery included its WLK 10,
WLK 800 F+, and WKS 2200 single-shaft shredders. These were seen on two booths – in the main hall, and in the show’s Recycling Zone. The WLK 10 single-shaft shredder stands is a
versatile solution for processing a wide range of plastic materials. With a robust design and V-rotor technology, it efficiently tackles plastic lumps, pipes, automotive parts and many other components. Equipped with a 1000mm rotor and a lift-up
screen basket for easy maintenance, the WLK 10 offers more convenience and accessibility for operators. Its adaptable configurations ensure optimal performance tailored to each application, while its integration into a two-stage solution further enhances its versatility and efficiency, says Weima.
Medical granulation CMG has launched a new series of small granula- tors that can be used in the medical industry. The new G17-MED series are several and all contribute to obtaining the highest degree of precision and cleanliness, regrind quality (homoge- neous particle dimensions and absence of dust), efficiency of operation. The new granulators are applicable to injection moulding and of blow moulding – but in the ET1 or ET2 configuration are suitable for extrusion. The new series is designed to obtain homoge-
neous regrind shape and dimensions, along with little to no presence of dust. One benefit of the new line is the ability to produce regrind with very small dimensions – which has no adverse impact on
