CUTTING SYSTEM HELPS GRANULATOR RUN AT HIGHER ENERGY EFFICIENCY

Piovan has introduced a new range of granulators that runs at lower power than compara-ble machinery, says the company. All new machines are fitted with a tangential cutting system: rotary blades are inclined with respect to the fixed blades and positioned as close as possible to the geometric tangent of the cutting circle – which improves cutting preci- sion. High production capaci-ties are achieved using smaller motors, while generating less heat and dust. This ensures a more regular cut and more dimensionally consistent regrind.

Piovan says they run at 25Wh/kg – lower than the industry standard of 40Wh/kg. The cutting chamber is made from machined pieces, which are then assembled ather than being cast or welded. This 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, says Piovan, as worn pieces can be replaced.
