Optimised energy utilization: drop from the industry standard of 40 Wh/kg to the new Piovan standard of 25 Wh/kg Most importantly, all new machines are fitted with an absolute- ly unique tangential cutting system. The rotary blades are in- clined with respect to the fixed blades and are positioned as close as possible to the geometric tangent of the cutting circle, therefore optimising and improving cutting precision. In this way, high production capacities are achieved using smaller mo- tors, with the additional benefit of minimising dust production and heat generation. These features ensure a more regular cut and more dimensionally consistent regrind. Without a cutting chamber of this quality, the regrind, in addi- tion to being irregular, will also have a higher dust content and will therefore be more difficult to process. N owadays, all industrial products are designed with a view to- wards recovering and recycling as many reject components as possible. In certain sectors, for example in the Food & Bevera- ge packaging sector, a decision is often made not to change raw material, in order to continue the existing recycling channels and methods. The need to develop recyclable materials influences and determines choices in the research and development sector. For this reason, granulators have assumed a fundamental role in the plastics sector, having been specifically designed to recover plastics processing waste and make it reusable. Piovan has redeveloped its range of recycling products introdu- cing very high quality machines able to satisfy all recycling needs throughout the plastics sector. In all cases where plastic is used in the packaging, medical, automotive, textiles and elec- tronics sectors, recycling is common practice, confirming the need for increasingly efficient and reliable granulators. Piovan has therefore introduced a new range complete with small, me-
