PPG has expanded its SEMCO high volume automated mixer line with two new heavy-duty mixers
for precision mixing of higher viscosity, multicomponent adhesives, sealants
and other chemicals in SEMKIT packages. The Semco model 1088HD mixer
and Semco 1188HD mixer are equipped
with robust motors to thoroughly mix
high viscosity aerospace adhesives, while
the Semco 1188HD mixer has added
capability for use in potentially volatile
and corrosive environments, like those
encountered by aircraft carrier maintenance operations.
According to Goldi Singh, PPG global
product development and engineering
manager for aerospace packaging, PPG
designed the new heavy-duty mixers with
stronger motors that can manage the
mixing process for high viscosity chemicals, especially aerospace adhesives.
“With 2016’s successful launch of the
Semco 1088 high volume chemical mixer,
our customers expressed a need for its
quality and productivity benefits for more
rigorous environments and materials,”
Singh said. “We fortified the Semco 1088
mixer with a stronger motor and holding
components to manage the mixing pro-
cess and ensure a full, thorough mix even
with high viscosity material. Mixing high
viscosity chemicals is no longer a chal-
lenge with the new Semco 1088HD and
1188HD mixers.”
The Semco 1088HD and 1188HD
mixers are equipped with a holder feature
that prevents the cartridge from spinning
during operation, which is common when
mixing high viscosity materials with oth-
er types of mixers. Operators simply in-
sert the Semkit package into the machine,
tighten the cartridge holder and run the
machine. The mixers operate until the
target stroke count is achieved.
The Semco 1188HD mixer is ATEX
Class II rated for use in potentially vola-
tile environments. Additionally, it car-
ries specific salt fog resistance for use
in some of the world’s most corrosive
environments.
Designed for both barrier style
and injection style Semkit cartridges,
Semco 1088, 1088HD and 1188HD
mixers can produce homogeneous
chemical distribution with one-touch
adjustment for the five most common
Semkit package configurations used
in the aerospace industry. In addition, they can automatically inject and
evenly distribute the correct amount of
catalyst into a prefilled injection style
Semkit package, which is required for
the material to meet application and
performance requirements.

Grieve Introduces New
850°F High Temperature
Walk-in Oven
No. 852 is an 850°F (454°C), high temperature walk-in oven from Grieve,
currently used for heat treating and baking varnish at the customer’s facility.
Workspace dimensions of this oven measure 60” W x 96” D x 72” H. 120 KW
are installed in Incoloy-sheathed tubular
heating elements, while a 7800 CFM,
5-HP recirculating blower provides combination airflow to the workload.
This Grieve oven has 8” insulated
walls and a 4” insulated floor. Additional
features include an aluminized steel interior and exterior and safety equipment
for handling flammable solvents, including explosion venting door hardware.
Controls on the No. 852 include a
digital indicating temperature controller
& manual reset excess temperature controller with separate contactors.
Ross Introduces Heavy-duty
and High-capacity Multi-agitator Mixing Systems
Ross VersaMix Multi-Shaft Mixers
designed for robust large-scale production enable reliable and repeatable batch processing of high-volume
viscous applications such as solid-liq-uid dispersions, thickened emulsions,
suspensions, pastes and gels. As a
multi-agitator system, the VersaMix
is easily adaptable for mixing at low,
intermediate and high shear levels, or
any combination necessary for powder
wet-out, deagglomeration, emulsification, homogenization, heating/cooling
and deaeration.
Agitator combinations, horsepower
selections, recipe controls and other features of the VersaMix are always tailored
to address the specific process demands
of any mixing application. One available
configurations is Ross Model VMC-750,
equipped with a dual-post lift, interchangeable 750-gallon mix vessels, and a
triple-agitator system consisting of a low
speed anchor, high speed disperser and
high shear rotor/stator assembly. Each
agitator is independently-driven and controlled from an HMI panel.
Laboratory models (1, 2 and 4 gallons)
are easily scaled to pilot/medium scale ( 10
and 40 gallons) and on to large capacity change-can models (from 100 through
1,000 gallons). Fixed-tank designs are offered up to 4,000 gallons capacity. CW
