Handle virtually any bulk solid material
Flexicon stand-alone equipment and automated plant-wide systems convey, discharge,
condition, fill, dump and weigh batch bulk materials dust-free
lexicon engineers and manufactures a broad range of equipment
that handles virtually any bulk material, from large pellets
to sub-micron powders, including free-flowing and non-free-flowing
products that pack, cake, plug, smear, fluidize, or separate.
Individual bulk handling equipment includes: flexible screw conF
veyors,
tubular cable conveyors, pneumatic conveying systems,
bulk bag dischargers, bulk bag conditioners, bulk bag fillers, bag
dump stations, drum/box/container dumpers, and weigh batching/
blending systems. Each of these product groups encompasses a
broad range of models that can be custom engineered for specialized
applications, and integrated with new or existing upstream and
downstream processes and storage vessels.
All equipment is available to food, dairy, pharmaceutical and industrial
standards.
For large-scale bulk handling projects, Flexicon's separate
Project Engineering Division provides dedicated Project Managers
and engineering teams on four continents to handle projects from
concept to completion. Working with each customer's preferred engineering
firm or directly with their in-house team, Flexicon adheres
strictly to the customer's unique standards, documentation requirements
and timelines through a single point of contact, eliminating
the risk of coordinating multiple suppliers.
Flexicon's worldwide testing facilities simulate full-size customer
equipment and systems, verify performance prior to fabrication,
demonstrate newly constructed equipment for visiting customers,
Flexicon offers stand-alone bulk handling equipment as well as
plant-wide systems integrated with new or existing processes
and study the performance of new designs.
The company recently doubled the size of its manufacturing facility
and world headquarters in Bethlehem, PA, and also operates
manufacturing facilities in Kent, United Kingdom; QLD, Australia;
and Port Elizabeth, South Africa.
Fast, homogenous mixing
The Bella XN fluidized zone mixer from Dynamic Air is a twin-shaft design that uses a
" weightless " central fluidized area to provide thorough yet gentle mixing of dry products
ing times of 15-30 s. A weightless
zone created by low-speed
counter-rotating paddles generates
low friction without
shear. This makes it ideal for
abrasive products and fragile
products that cannot tolerate
rough handling. Even flakes
or spray-dried bodies remain
intact.

by Dynamic Air achieves fast,
high-capacity, low-shear, precision
mixing of either dry bulk
solids or liquids with solids.
Regardless of particle size,
shape or density, materials are

gentle action, with typical mixThe
Bella mixer consists
of twin drums which have
two counter-rotating agitators
with specifically angled
paddles. The paddles sweep
the entire bottom of both
mixer drums and yet allow
the mixer to be started under
full load (Figure 1). The material
in the mixer moves in a

ZONE B
horizontal counter-clockwise
direction at the perimeter
while simultaneously moving
both left and right in the center
(Figure 2). The material in
Zone B (Figure 1) is in its normal
gravimetric state as it is
being moved and dispersed.
In Zone A, a weightless zone is
created which effectively lifts
the ingredients to an almost
weightless state, allowing them
to move freely and randomly,
regardless of particle size and
density. Thus the two zones'
interaction becomes highly efficient
as every particle moves
rapidly to create a highly homogeneous
mix, the key to the
Bella mixer mixing technology
for fast, precise mixing.
The Bella mixer is available
in stainless steel and mild steel
construction.
