Modern Process Equipment
Focus
commodates 50 to 80 bags.
The hopper discharges into
an enclosed, flexible screw
conveyor, designed to handle
a wide range of materials,
including free- and non-freeflowing
bulk materials from
large pellets to sub-micronsized
powders. - Flexicon

Gentle conveying of
heavy loads
The Chain-Vey tubular drag
conveyor (photo) has been
proven to convey hundreds of
different products, including
ingredients for cement. The
system transports products
gently and efficiently, both
vertically and horizontally,
in a dust-tight environment
without product degradation
or declassification, says
the manufacturer. Other
features include a case-hardened
carbon-steel link chain
to convey high bulk densities
(cable systems cannot handle
the load) and XP (explosionproof)
rating upgrading capability.
Systems are available
for handling 650, 1,000
and 1,400 ft3/h. - Modern

specifications. Structural components
are prepared with a
glass-bead finish that is applied
in a dedicated, in-house metaltreatment
facility. This results
in smoother, more hygienic surfaces
that are free of imperfections,
such as weld scars, says
the manufacturer. - The David
Round Co., Streetboro, Ohio

These sanitary receivers
are easy to clean
The P-Series Sanitary Receivers
are designed to convey difThese
feeders handle
up to 850 ton/h
The Heavy Duty Electromagnetic Vibratory
Feeders (photo) are suitable
for handling coal, ore, aggregates, slag
or whenever high-volume, controlled
feeding is required. The feeders feature
an energy-saving intermeshed
a.c./permanent magnet drive. The
feeders are available in nine models
with capacities of up to 850 ton/h, and
can be supplied with overhead drives,
multiple-drive arrangements, " grizzlie "
decks and dust covers to meet
users' application requirements. They
feature an electromagnetic design that
has no moving parts, such as shafts,
cams or bearings, thus eliminating the
need for lubrication. Controls come
standard in NEMA 12 enclosures for
dusty environments; other enclosures
are also available. - Eriez Manufacturing
Co., Erie, Pa.

A jib crane for
pharmaceutical manufacturing
These new all-stainless-steel articulating
jib cranes (photo) are ideal for
lifting bulk bags or other materials
(up to 1,000 lb) in cleanroom environments.
Explosion-proof models of
these jib cranes are available to meet
electrical standards required in hazardous-environment
processing areas.
The cranes feature fully enclosed mechanical
components, including wirerope
hoist, gearbox and motor drum.
Lift height and boom/knuckle configurations
can be varied to meet user

ficult powders for continuous conveying
applications, such as hopper
loading and loss-in-weight feeder refill
applications, that require a high
level of sanitary design and frequent
cleaning. The receiver body is made
of stainless steel (DIN 1.4404, AISI
316L), with internal and external
electro-polished surfaces. Modular
design allows for easy disassembly
and cleaning. Tri-Clover fittings
allow for quick disconnection from
the conveying and vacuum piping. All
units have reverse-jet filter cleaning.
Models available include P-10, P-30
and P-100 with conveying rates of up
to 4,000 kg/h (8,800 lb/h). - K-Tron,
