processing | Continuous and batch mixers Plasmec recently upgrad-


ed its testing room, where customers can set up mixing tests on various types of plastics compounds. The facility houses an HC Combimix 300/1000 unit that combines a TRM heating mixer with an HEC horizontal cooler, an RV 50-100 combining a TRM with an RFV vertical cooler, a TRL 13 laboratory mixer, and a TRR 150 container mixer. A test room is also the latest addition to the


Promixon site in Italy. The test facility houses an Xblend-MC/400/1200 heating/cooling mixing plant comprising an XM turbomixer and an XC horizontal cooler, and an FX-300 high-speed container mixer. 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 unidentified producer of luxury vinyl tiles (LVTs) with operations in Belgium and the US.

Masterbatch focus 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. HF Mixing Group has various


batch mixers for production of a wide range of materials, 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 in use, you can stop them when you want. It’s a more transparent 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 com- pounding 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.” For recycling operations, Limper says that larger units can even handle car bumpers that have simply been cut in half. HF has units with drive powers ranging from 500kW up to 2.5MW. 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 masterbatches 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. Compounding World will be taking a closer look at the machine in our Laboratory Compounders feature in the December issue.


Researching the mix Ajax Equipment (which was not at K2016 as much of its business is outside the plastics industry) reports that its Continuous Twin Screw Mixer is the primary mixing technology being used in research being carried out in the Project Chariot advanced manufacturing supply chain
