Powder Metering at Ultra Low Rates

Powder Metering at Ultra Low Rates
Micro ingredient and ultra low dosing of bulk solids are becoming a specialist sector for Trantec Solids Handling. Traditional metering feeders with oversized auger screws are often coerced into running very slow to deliver small quantities of powder, this approach can compromise the performance and produce erratic dosing.

For the last 25 years, Trantec has been designing and manufacturing metering screw feeders and is now applying this expertise to the challenges posed by minor ingredient dosing. Trantec’s Micro and Nano feeder range takes proven feeding technology and applies it to the miniature world of ultra-low dosing of powders, flakes, and granules. Trantec utilized computer modeling and 3D printing to eradicate the complex manufacturing problems created by the production of such a compact metering feeder.

Featuring auger screws as small as four millimeters in diameter, including multi-start flights which offer accurate metering and steady flow at very low rotational speeds, Trantec micro feeders are extremely versatile. Product agitation and conditioning for cohesive powders are provided by an independently driven agitator or stirrer giving variable speed or pulse running as required by the application.

Feed ranges down to milligrams per hour rising to many grams per hour are typical. Loss in weight, gain in weight and gravimetric versions provide even greater accuracy and controllability. Refill of the compact feeder can be done manually or with a second volumetric screw feeder under the control of the Micro feeder.

Trantec Micro and Nano feeders are manufactured using precision machined components produced in our factory. Our investment in the latest CNC machine tools keeps these micro feeders cost-effective whilst maintaining the highest quality levels and a minimal supply chain. Quick-release, easy-clean features are included as standard. Low voltage operation makes these machines safe to use in laboratory and industrial environments alike. Major components such as the conditioning sections are machined from solid stainless steel billets making the feeder robust and capable of operating in harsh environments.
