Transformer cleaning package includes a
three-piece mixing bowl with swing away lid
production data collection. The FX series mixers are
primarily designed for masterbatch, compound, powder coatings and premixed powders applica- tions and include new lifting and rotation units and sealing system. Again, revised mixing tools have resulted in a 30% reduction in typical mixing times. Promixon claims to have built up an impressive
customer list over the past two decades, pointing to the recent delivery of seven heating/cooling mixing plants to a major producer of luxury vinyl times (LVTs) with operations in Belgium and the US. It also supplied an advanced heating/cooling mixing system to specialist Italian PVC film producer Mondoplastico last year. The system comprises a 1,200 litre capacity high speed turbomixer and two 2,500 litre high efficiency horizontal coolers. On the Battaggion stand at K 2016, Sales Engineer Simone Belotti stressed the merits of the company’s double-arm sigma blade kneaders for medium and high viscosity materials such as masterbatches. These are

available with either a tangential or overlapping action and with chamber volumes ranging to 5,000 litres. As well as its principal range of models with tilting
chambers, Battaggion also offers IPC sigma kneaders with single or twin discharge screws. One of its more recent developments is the upgraded IPCAPG model for production and granulation of colour masterbatches, which is available with an output capacity ranging from 150 to 600 kg/h of LDPE masterbatch.
Masterbatch focus HF Mixing Group has various batch mixers for produc- tion of a wide range of materi- als, including masterbatches and flooring compounds. Speaking during K 2016, Managing Director Andreas Limper highlighted the versatility of the company’s Umix universal horizontal mixers for mixing and kneading low to high
viscosity products. “You can get very high
shear forces, and they are flexible 36 PIPE & PROFILE EXTRUSION | January/February 2017
in use, you can stop them when you want. It’s a more transpar- ent process. You can adjust the speed, the fill factor, the
temperature, the ram pressure, the order of material dosing,” he explains.
“That is why batch mixers
are still used in a lot of niches, and we are doing a lot of research to expand their use for compound- ing natural fibres, for
example, and recycling. Our machines are very good at handling low-grade glass fibres and processing WPCs with original moisture contents of up to 10%. With continuous units, residence time can be just a few seconds, but with batch mixers it can be a few minutes, so they are much better for drying.”
Continuous performance Farrel Pomini showed its new CPeX laboratory continuous mixer at K 2016. Scheduled for availability in late Q1 2017, this unit is being targeted mainly at existing customers of the company’s full production units who until now have had to do laboratory work on twin-screw compounding extruders. The company says the new unit is ideal for lot sizes
of 10-30 kg/h, and is designed for use with master- batches and compounds of temperature sensitive, highly abrasive materials as well as highly filled or highly pigmented materials requiring intensive mixing while maintaining low processing temperature. The CPeX, which Farrel Pomini calls a Compact
Processor, features counter-rotating and non-in- termeshing rotors and can be configured to both standard and XL formats. It is the first time the company has supplied both configurations on a single machine. “The CPeX Compact Processor is designed to help
compounders successfully test and develop the most challenging formulations in a lab environment,” says Paul Lloyd, Business Unit Director at Farrel Pomini.
