Quick change for micro- drip products


Maillefer’s dual bowl configuration allows producers of irrigation products to switch quickly from one product to another. A consolidated frame


allows producers to make set-up adjustments in a few simple steps. The operation of switching to a waiting bowl – filled with new drippers – takes less than half an hour, says the company. It is especially simple when changing to drippers of a similar size. More important dripper


differences may require additional adjustments, but they remain quite simple with a second consolidated bowl. Changing the insertion tool and adjustments are easy, thanks to preset positions and graduated scales built into the fixed frame. ❙ www.maillefer.net


WOOD-PLASTIC COMPOSITES Extruding temporary housing in WPC


Battenfeld-Cincinnati used a line based on a FiberEx 93 extruder to make a special ‘H-profile’ at its recent open house event during AMI’s Wood-Plastic Composites conference. The profile, made from 72% wood fibre and 28% polypro-


pylene, was a key component in temporary housing made entirely from WPC profiles. The FiberEx 93 extruder has a 34D processing length and maximum, output of 420kg/h. It is equipped with a degassing system. The geometry of the gas outlet valve and the screw prevents leakage of melt particles from the processing chamber and ensures a high degassing performance. Line elements included a Beologic profile die, EMDE


material conveyance system and a ConPro dosing system. ❙ www.battenfeld-cincinnati.com ❙ www.beologic.com

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


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 simplified and less operating space is needed.


rather 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. One model in the new


range, the N35-60, features a


Fast access to the machine is another important factor, given that in certain operating conditions cleaning may be necessary on a daily basis. This is a response to a specific request by users who need to insert the granula- tors at the end of production lines where space is often limited.


The new range guaran-


tees energy savings of 15-35% depending on the application, says the company. ❙ www.piovan.com
