K-Tron to Premier Revolutionary New Feeder Technology at ChinaPlas 2003

Pitman, NJ--- (September 25, 2003)--- The K-Tron Feeder Group will premier a revolutionary new concept for feeding bulk materials at Chinaplas (Booth #2A01 hall 2), December 4-7, 2003 in Beijing, PR China. Known as the K-Tron Bulk Solid Pump (BSP), this new K-Tron feeder does not use the usual screws/augers, belts or vibratory trays to convey the material. It utilizes positive displacement action to feed free flowing materials with astounding accuracy, offering uniform discharge, consistent volume and gentle handling.

The BSP feeder has vertical rotating discs that create a product lock-up zone conveying the material smoothly from storage hopper to discharge outlet, achieving true linear mass flow. Utilizing a simple design and the principle known as “lock up,” the material in the feeder is moved together in true positive displacement, producing excellent linearity and breakthrough accuracy levels. With no pockets or screws and only one moving part, the compact feeder is cleaned in seconds, making it ideal for applications with frequent material changes.

Both gravimetric and volumetric versions of the BSP will be available for free flowing materials, such as pellets and granules. Two models will be introduced initially. The BSP-100 will feed from 2 to 200 cubic dm/hr (0.07 to 7 cubic ft/hr). The BSP-125 will feed from 9 to 900 cubic dm/hr (0.32 to 32 cubic ft/hr). K-Tron will also introduce a new gravimetric blender utilizing BSP feeder modules.

The illustration shows how the BSP uses positive displacement technology and a unique operating principle - use of a product "lock-up zone" that smoothly conveys material from hopper storage to discharge. In the illustration four zones are color coded: Zone 1 blue)-- Consolidation- where interparticle forces produce lock-up at the end of the zone; zone 2-- (light blue-- rounding the hub) rotation--material rotates as a solid body; zone 3 --

relaxation (purple)-- interparticle forces fall below lock-up threshold;

zone 4 (light purple- turning to white)-- Active discharge.
