Software for Twin-Screw Element & Barrel Configurations Burgsmüller in Einbeck, Germany (a KraussMaffei Berstorff company) has developed software for configuring screw elements and barrel housings for twin- screw extruders. Called ScrewCon, the software can be used for configuring the processing sections of a wide range of different twin-screw extruders. The software provides tailored screw-element and barrel-housing configurations for any application with true-to-scale visualization. In addition to in-depth process- engineering know-how and the specific rating of conveying, kneading, mixing or retaining elements, ScrewCon software offers tips on the optimum material selection for the screw elements and housings to maximize service life and output rates. ScrewCon has a library of about 3000 screw elements and barrel housings for different twin-screw extruder brands, types and sizes. If the required elements are not available, Burgsmüller can easily add them using the basic data all machine owners have on hand. Burgsmüller can also provide compounders with the most cost-effective screw configuration by integrating special elements as well, like multi-process elements, shoulder kneading disks or other mixing elements. +49 05563 705-0 • COMPOUNDING High-Speed Mixer Provides Dispersion, Planetary Stirring PowerMix Model PDM-10 from Charles R. Ross & Son Co., Hauppauge, N.Y., combines high- speed dispersion with planetary stirring action. This is said to impart high shear to hard-to-mix applications with low flowability. Pictured are two PowerMix machines with interchangeable mix vessels. Beyond a traditional kneading action, the mixing mechanism of this proprietary planetary design is suited to heavy pastes and slurry-like applications involving a considerable amount of powders that need to be wetted out and dispersed uniformly. These 10-gal models feature an additional sawtooth blade on each disperser shaft, doubling the shear-input capacity of the mixer. A rectangular stirrer orbits the vessel, effectively exposing the entire batch contents to the shearing action of the dispersers. For more viscous applications prone to climbing up the stirrer, patented high-viscosity blades are available with a helical curvature that pushes product forward and downward. Fully automated PLC recipe controls and data-acquisition systems are available. 800-243-7677 • Controller Supports Two Independent Feeder Lines FEEDING/LOADING COMPOUNDING Coperion K-Tron (U.S. office in Sewell, N.J.) has added new features to its K-Vision software. The K-Vision controller is a graphical operator interface for controlling multiple devices such as feeders or feeder-refill vacuum receivers in a process. With the release of K-Vision Software version 2.0, it can now handle a total of 24 devices (e.g., KCM feeder controls or MPC refill controls) in one or two lines. The previous version managed a maximum of 16 feeder controllers in a single line. K-Vision uses a 12.1-in. color LCD display together with a touchscreen. It offers a quad-screen display mode for viewing multiple pages on one feeder or a single page on multiple feeders. Designed for simple operation and fast and easy startup, K-Vision offers graphic visualization of process information, utilizing flexible trend graphs. This feeder interface offers event logging and supports all of the different feeding control types for both continuous and batch operation. Easy to maintain, K-Vision software updates can be accomplished with a compact flash card or a USB flash drive. K-Vision offers a variety of remote-access options. A second K-Vision can be connected via Ethernet as a remote interface for visualization and control of feeder and line parameters. K-Vision also comes with a VNC server, allowing any VNC client—on a PC, tablet or smartphone—connected to the same network to be used as a secondary user interface. In addition to the current connectivity options—including VNC, Ethernet/IP, Profinet, Modbus TCP—K-Vision now also has email capability. 856-589-0500 • @plastechmag 47 Plastics Technology N E W P R O D U C T S F O R P L A S T I C S P R O C E S S I N G With Technology Keeping Up Compounding Equipment PRODUCT FOCUS
