Pneumatics Product Line

November 30, -0001

The K-Tron Process Group has several additions to its feeder and premier pneumatics product line. K-Tron's new Micro Cone feeder, features a highly innovative screwless feeding mechanism that accurately doses free flowing color, masterbatch or additives into a blending system or directly in the process screw of an extruder. Using a simple induced flow rotating tube/cone, the Micro Cone Feeder doses down to a few granules at a time, with a feed rate range of 0.2 to 2 dm³/hr (0.007 to 0.07 cu ft). With use of an extension tip, the feeder can feed as low as 0.1 dm³.

Additionally, K-Tron's new extrusion control package offers the ability to control the extruder speed so that its output has a predictable and repeatable mass flow. By accurately measuring material throughput, gravimetric extrusion control can compensate for material and process variations and provide more consistent end product quality. It is primarily targeted for use with single screw flood fed extruders in both mono- and co-extrusion applications such as profile extrusion, cast sheet, blown film, cable coating and laminating. Gravimetric extrusion control is virtually a necessity for multi-layer co-extrusion systems. Its benefits include exact control of end product quality, significant savings in material costs, highly accurate multi-layer co-extrusion of films, longer production runs due to consistent extruder output and the ability to detect problems before the product goes out of specification.

Premier Pneumatics has also introduced the new Series 4 Microprocessor Controller (Series 4 MPC) for operating up to 24 vacuum receivers on one blower. The controller consists of a central control unit which features an easy-to-use, touch-sensitive keypad. The operator controls the whole system, including turning receivers on and off and setting draw times from one central location. The Series 4 MPC can be integrated into the K-Tron Smart Connex feeder controls, providing one simple control solution for both feeders and vacuum sequencing receivers. The unit is shipped pre-programmed, eliminating complex logic programming. Additional features include CE conformity, LED visual indicators, easy on-screen system setup, back-up blower capability, blower shutdown for automatic bag filter cleaning, password protection, built-in networking capability and computer interfaces for data acquisition.

Premier Pneumatics introduces its ProBlend Zone Blender for blending or homogenizing free flowing bulk material within a hopper or silo. With its special geometric shape, the compact and simple Zone Blender provides multiple flow zones in which the material can pass through at different velocities and residence times. As a result, the discharged material contains a uniformed blend of material from the hopper or silo. The Zone Blender uses a combination of mass flow (first in – first out) with funnel flow (last in – last out) to help homogenize the blend and reduce the effect of segregation in re-circulating, batch or continuous systems, or any application requiring the blending of materials.
