PF-S Volumetric Powder Feeder

Feeds difficult powders such as Cabosil®, TiO2 and other pigments without bridging or clogging the hopper or the screw. Exclusive trough design defeats flooding by dissipating kinetic energy of material stream at initial fill. Agitator and screw overwind prevent material compaction or arching over screw flights. Feeder disassembles easily for total cleaning, eliminating contamination problems when changing materials, (Download PDF) Proven ability to feed difficult powders PF-S Volumetric Powder Feeder controls both flooding and clogging problems associated with difficult-to-handle powders. Unique feeder trough effectively de-aerates and contains the powder at the initial fill cycle to prevent flooding. Independently driven agitator maintains optimum material conditioning while screw speed can vary to control flow rate. Material does not build up within the continuous screw tube liner, preventing binding or erratic feed.
 

Power Wall Screw Feeders

Moves the materials that other volumetric feeders can't budge. Pneumatic PowerWall™ diaphragms provide reliable material flow. Pulse action is independent of feed rate, resulting in wider turndown capability. Fully adjustable while operating, to fine tune performance. Built to survive, with welded steel box frame construction for long life. From gentle flutter to pounding pulse THAYER "PW" Volumetric Feeders provide consistent, reliable volumetric metering of anything from delicate products to the most stubborn materials. Conventional flexible wall feeders have mechanical devices which are only capable of slight hopper wall movement. They just do not have the "kick" needed to move hard-to-handle materials. PW Feeders have safe, reliable pneumatic PowerWall diaphragms which can be adjusted from gentle flutter to pounding pulsation, to consistently and reliably feed even the hardest-to-handle materials. Random wall action prevents stable arch formation or material compaction, keeping screw flights filled. Unique construction Elastomeric diaphragm is driven by regulated air pressure, with independent cycling control for each wall. Reinforced diaphragm sheet combines strength and flexibility needed for long life. It is completely supported by the steel housing, is inexpensive, and is easily replaced.

   

 

LRS-F Screw Feeders

Feed range up to 10lbs/hr @ 50 pcf material. Exclusive Powder Feeder Technology Thayer Scale's feed chamber is designed to eliminate common problems associated with feeding powders. The feed chamber, with conditioning screw, assures precise, reliable delivery of material to the feed screw. Eliminates material build up, screw starvation and binding, assure steady uninterrupted flow. Fast and Easy to Clean The LRF is designed for fast, easy and thorough clean out. The feeder completely disassembles in less than one minute. No tools or special skills are required. High quality, rugged, stainless steel (material contact parts) construction assure years of reliable, trouble free operation even in the most severe industrial environments.

Handles a wide range of material bulk densities at low to medium feed rates. Unique low rate feed screw eleminates the need for old fashioned, expensive, difficult to maintain twin screw designs. Patented "compound flight" feed screw design works in conjunction with patented "U-trough" feed chamber to eliminate common problems associated with feeding powders such as screw starvation and binding. Exclusive Powder Feeder technology Patented "compound flight" feed screw design works in conjunction with Thayer Scale's "U-trough" feed chamber to eliminate common problems associated with feeding powders such as screw starvation and binding. Patented "U-trough" feed chamber with independently driven agitator assures precies, reliable delivery of material to the feed screw. Eliminates material build up, controls material aeration. Delivers a steady, predictable flow. Fast and easy to clean PFM-S is designed for fast, easy and thorough clean out. Feeder completely disassembles in less then one minute. No tools or special skills are required. With optional rotating hopper, feeder does not have to be removed from production line in order to clean out or change screws. High quality, rugged, stainless steel construction assures years of reliable, trouble free operation even in the most severe industrial environments. PFM-S Powder Feeder
