Extrusion 2-2018

31 Extrusion 2/2018 Innovative design and manufacturing methodolo- gies put the new Piovan granulators a step ahead of current solutions available in the market The cutting chamber is made from machined pieces, which are then assembled rather than being cast or welded. This design has enabled the construction of high-precision components that improve the efficiency of the cut and the quality of the ground product, while improving the life of the granulator, as worn pieces can be replaced. Another distinctive feature of the Piovan granulators is the possibility for customisation. Even the most basic versions can be modified to suit the specific needs of the process. N35-60: the state-of-the-art granulator One of the very distinctive models of the new Piovan range of granulators is the N35-60, a machine encom- passing all of the characteristics described above, in ad- dition to featuring a 90° adjustable hopper for four loading positions, ensuring that if fed by conveyor belt, the direction of the belt can always suit the granulator hopper inlet. Maintenance is therefore simplified and less operating space is required. N35-60 is part of a family of three granulators designed specifically to process large pieces or such as injection moulded food containers; large bottles or cans (blow moulding); tanks, bins, (rotational moulding process). These objects are normally quite large and light and can therefore bounce and be difficult to cut. Piovan size reduction solutions: excellent results using less energy Piovan granulators are also fitted with energy efficient electrical and control systems: the entire transmission system has in fact been revised to achieve effective energy savings when used 24/7. Even if the granulator doesn’t work continuously, it is possible to optimise peak loads to reduce energy consumption. For example, in the case of blow moulding, the granula- tor is used heavily at start-up, while during operation it is used intermittently to grind 20 to 30 percent of pro- duction. Between one mould and another there are a series of idle periods in which the granulator is inopera- tive, even if the motor remains on. The energy saving system intervenes in this case to manage the idle pe- riods and optimise consumption. The new range of Piovan high-efficiency granulators guarantees energy savings between 15 and 35 percent depending on the application. PIOVAN S.p.A. Via delle Industrie 16 - 30036 S.
