Lab compounders | machinery feature
Kneading, mixing and milling in the lab It’s not just twin-screw extrusion that is being carried out in the lab. Devices for other compounding processes such as kneading, mixing and milling are also being miniaturised so that they can be successfully used for product development and small-lot production. Buss developed and recently began to manufacture the MX 30, a new 30-mm lab extruder with a four-flight Kneader design to match the full-scale Buss four-flight extruders. The MX 30 will scale up to the four-flight Quantec, used for PVC, and the four-flight MX series, used for olefin-based compounds like HFFR cable, nanocomposites, highly-filled masterbatches, and other applications. “This new lab line is useful for development work that
will then go to one of the 200 or so four-flight machines now in operation, and can also be used as a tool for customers interested in investigating the new kneader technology,” explains Mike Irish, vice president of Buss Kneader Technology at the company’s US subsidiary. The existing Buss lab machine, the MKS, is a three-
flight design. While the MKS and the new MX 30 could be used interchangeably to scale-up to either Buss three-
flight or four-flight machines, the new lab machine meets customer requests for a four-flight lab line. The MX 30 will have a standard 22 L/D split barrel to
give users the most flexibility. It also incorporates inlet screws with back venting for separate addition of feed- streams, which matches the production set-up for even better scalability or for use in semi- work production. “The kneader can accept direct injection of liquids at any point along the barrel,” notes Irish. The line includes a 40-mm crosshead extruder to build pressure for pelletizing, and can be equipped with either a standard strand pelletizer or an optional hot die-face pelletizer. The MX 30 will debut at the NPE 2012 International Plastics Showcase in Orlando, Florida this coming spring. B&P Process Equipment and

The advance into a new performance dimension of compounding technology. The new ZSK Mc18
twin screw extruder of Coperion, formerly Werner & Pfl eiderer, is the most pro- ductive high performance ZSK of all time. With a specifi c torque of 18 Nm/cm3
it stands for
considerable throughput increases with improved product quality and the widest processing window on the market – to provide you with a unique technology advantage. That’s what we mean when we say “confi dence through partnership”.
