Ross Offers Vertical Blenders
Designed for low-impact blending, Ross
Vertical Blenders feature a conical vessel
and a slow-turning screw that can thoroughly agitate a wide variety of materials including powders, granules, pellets,
fibers, slurries and pastes. The screw
turns on its own axis while being rotated around the vessel by an orbital arm.
Batch materials are lifted to the uppermost level of the cone then cascade slowly
back down in regions opposite the moving screw. This mechanism is not only
advantageous for blending friable ingredients but also for coating solids with a
minor liquid component and for vacuum
drying of heat-sensitive applications.
Available in many sizes from 1 through
500 cu.ft., Ross Vertical Blenders do not
require a bottom support bearing to keep
the screw steady so discharge is always
virtually 100 percent complete. This “
unsupported screw” design also simplifies
cleaning and maintenance.
Union Process Manufactures
A Pair of S-400 Attritors
Union Process, Inc., a manufacturer
of particle size reduction and dispersing equipment as well as related services for a broad range of research and
industrial applications, has built two twin
S-400 Attritors. The wet grinding batch
Attritors were built for a customer grinding Alumina. The customer’s throughput
requirements dictated the need for these
two large production mills. The starting
size of the customer’s material was approximately 300 microns.
Union Process was able to reduce the
size of the starting material to as small as
one to two microns in a very short time
(especially when compared to a ball mill).
Union stated that attritors are simple to
operate, very energy efficient and require
no premixing. The tanks are constructed
of 304 stainless steel, ceramic-lined and
are jacketed for cooling. The shafts are
stainless steel and the arms are sleeved
with tungsten carbide. The slurry capacity
of each S-400 Attritor is approximately
280-300 gallons. The grinding media
loading for each mill is approximately
300 gallons. Each S-400 is powered by a
75 HP, 2-speed, TEFC motor.
Red Devil Equipment
Introduces New Product
Red Devil Equipment Company introduces the all-new ergonomically designed DynoLift Transfer Cart. Safely
and easily move hundreds of pounds
of materials in pails, boxes, cartons or
more in virtually any commercial environment. Capable of carrying three five-gallon pails and four four-gallon cartons,

course of a day while virtually eliminating the risk of injury.
Grieve 750ºF Electric Walk-
in Oven for Drying Resins
Grieve offers model No. 941, an elec-
trically heated 750ºF (~399ºC) walk-in
oven, currently used for drying resin
mixtures. Workspace dimensions on
this oven measure 48”W x 48”D x
72”H. 60KW are installed in Incoloy-
sheathed tubular elements to heat the
unit, while a 4200 CFM, 3-HP recircu-
lating blower provides horizontal air-
flow across the load.
This Grieve walk-in oven features 6”
insulated walls throughout, Type 304 2B
stainless steel interior with continuously
welded seams, stainless steel exterior with
#4 brushed finish and heavy-duty double
front doors. No. 941 also features a digi-
tal programming temperature controller
and 10” diameter circular chart recorder
onboard.
Huber Launches Hydral
Coat 2 Ultrafine Alumina
Tryhydrate
Huber Engineered Materials has intro-
duced Hydral Coat 2 Ultrafine Alumina
Trihydrate (ATH) for use in coil coatings
and other high performance coating-
related applications. In coatings applica-
tions with low film thicknesses, extenders
are not commonly used because they
adversely affect the gloss and/or perfor-
mance properties. Huber conducted an
analysis comparing high-gloss white and
black coil coatings without extenders
versus the same coatings extended with
Hydral Coat 2 Ultrafine ATH.
The coatings delivered the same
performance, including 2,000 hours of
QUV weathering. In addition to a par-
tial replacement of TiO2, Hydral Coat
2 Ultrafine ATH replaced a portion of
resin content. The result is a lower cost
per gallon without any adverse impact on
aesthetics, flexibility or durability.
Emerald Unveils FOAM
BLAST 4213 and 4149
Defoamers
Emerald Specialties Group, a business
group of Emerald Performance Materials,
has introduced two new 100 percent active FOAM BLAST defoamers for coatings and graphic arts, including both
aqueous and energy curable (UV/EB)
applications.
FOAM BLAST 4213 is an innovative, organo-modified silicone (OMS)/
synthetic antifoam product, while
FOAM BLAST 4149 is a synthetic block
copolymer composition developed as a
non-silicone alternative, according to
the company.
Both new products offer excellent initial and long-term foam control for products such as interior and architectural
coatings and flexographic inks, according
to the company. FOAM BLAST 4213 and
4149 can both be added at low use levels
during pigment grinding or let-down to
achieve excellent long-term foam control
and a superior finish free of defects, craters or fisheyes caused by foam, accroding
to the company. Both products are low-VOC and free of alkylphenol ethoxylates
(APE).CW
