Gravimetric Blenders - MBWB
Foremost manufactures gravimetric blenders to meet the metering
and blending needs of the plastics industry. Our Mini-Batch Weigh
Blender is a fully integrated, automatic weighing system which
meters individual ingredients sequentially into a centrally mounted
weigh chamber.
The metering feeders offer dual speed (bulk/dribble) operation
for maximum throughput while maintaining high accuracy. Each ingredient
is weighed and totalled. When a batch is completed, it is held until
called for. This allows the system to be integrated with any existing
process.
Design Features
Our standard gravimetric blenders have feature up to four ingredient
stations located over an integral weigh chamber. Each station consists
of a modular 1.5 cu. ft. quick change hopper and vibratory feeder
assembly. The central .75 cu. ft. weigh chamber is suspended from
a hermetically sealed load cell, and all components are mounted
to a common rigid frame.
Interchangeable hoppers are complete with sightglass, handles,
snap-on lid, and maunal slide gate. Virbratory feeder asssemblies
are bolted to the support frame in individual cradles. This feature
facilitates quick removal for maintenance. The patented weigh chamber
suspension provides highly accurate, reproducible
weighing while reducing the potential for load cell damage inherent
in other systems.
The MBWB controls for our gravimetric blenders consists of separate
high and low voltage panels, minimizing the effects of electromagnetic
noise and enhancing system reliability. The low voltage panel houses
the field proven Foremost FDP IV digital weigh processor interfaced
with an industrial programmable controller. Operator controls are
located on the face of the panel and twin LED dispalys indicate
all system operating parameters on both a real-time and accumulated
basis. Data entry is though a numeric touchpad secured by a keyswitch.
Controls include full alarm and condition indicators.
