avoided. This type of material feeding also allows the use of motors with lower kilowatt power, meaning lower electricity consumption.” Regarding increased profitability long-term, he


holding modules and not on a holding block. CMG says: “The rotation of the rotor does not


produce the very detrimental “drag” effect, meaning the mass of material being ground in the cutting chamber does not rotate with the rotor producing lots of dust and fine particles, that will all become waste through the washing line. The production of fine particles is reduced to few percentage points, versus a common 15% or more from conventional granulators.” The rotor is an open-type design and occupies only 30% of the cutting chamber volume. This feature alone allows more than double the quantity of material in the cutting chamber, says CMG. The new cutting chamber has the so-called “tangential set up”. There is no need for feeding aid devices, commonly used with conventional granulators. CMG has also developed the new G26 granulator

line, for use with injection moulding, blow moulding and extrusion processes. There are three models: G26-30, G26-45 and G26-60. The standard configu- rations cover capacities from 50 kg/h up to 300 kg/h. The line features integral sound enclosure and an innovative feed hopper design to accommodate the widest variety of shapes and dimensions of the parts to be ground. CMG says all models operate in high-efficiency conditions, are equipped with EISA premium-efficiency motors and can have AMP controls. Energy utilisation is 20 Wh/kg. On the topic of energy conservation,


Jürgen Schnitzer, Sales and Marketing Manager at Neue Herbold based in Sinsheim- Reihen, Germany, says: “Higher output can be achieved using a so-called forced feed, whereby material will be positively fed into the grinding chamber via force screws and not only by gravity. This has another positive effect. Due to the forced feed of the material, the grinding chamber is always full of material to be ground and therefore spike of the amperage is

says: “Another quickly developing area is contin- ued optimisation of the cutting geometry with the aim of increasing the lifespan of cutting tools.” Smart control systems have become a key component in efficiency and energy conservation. The latest generation are compatible with standards for Industry 4.0, which now dominates the market- place and is a vital consideration for customers. Schnitzer claims the benefits of Industry 4.0 are many and varied. “To begin with, it facilitates a simple and intuitive interface between man and machine, allowing the operator to manage the granulator using PLC (programmable logic controller). Remote maintenance and/or diagnos- tics or problem solving is made easier, and compliance with the latest safety parameters, health, and hygiene standards is automatic.” “Industry 4.0 is predisposed for connection to factory computer systems with remote loading of instructions and/or part programs and allows automated integration with the factory logistics system or with other machines in the production cycle,” Schnitzer continues. “Crucially, it also expedites continuous monitoring of working condition and process parameters through suitable sensor sets and adaptivity to process drifts.” For systems to be certified Industry 4.0 compli-


ant, they must be fully prepared for connection to SCADA factory information systems, MES or ERP with Ethernet connection and standard TCP/IP protocol OPC-UA, which facilitates the exchange of production data, including machine status, electri- cal absorption, batch management times, mainte- nance intervals, and alarms and/or signals. This means that any weak spots or deficiencies can be quickly identified and remedied, making the entire operation more streamlined and effective. At the K2022 exhibition, Rapid Granulator
