Blastec®
is the originator of the 1,760 RPM direct drive shot blast
wheel. Since its introduction in 1976, many others have attempted
to equal our success. What keeps us
ahead of the pack? Our design. Now in its 7th generation,
our original concept still remains the leader in the industry:
A large diameter wheel turning at a low RPM and delivering
the maximum amount of abrasive per square inch. While we
have improved the maintenance aspects of the Blastec®
wheel through these generational changes,
parts for all wheels remain available and each generation
is easily upgradeable to current specs.
Use
of the Blastec®
wheel
increases productivity by up to 50% and extends the life of
the blades by 100% or more, and impellar and control cage
life by 300% or more, compared to competitive models. In production
tests and operating cost
studies, the Blastec®
wheel outperforms conventional 13 inch - 19 1/2 inch diameter,
2,250 - 3,600 RPM wheels. It also lowers dBA noiselevels by
up to 20% compared to the V-belt wheel assembly, and thus
eliminates the need for sound suppressors. |

The multi-patented
24-inch diameter Blastec®
wheel incorporates a double-sided runnerhead design, and two- sided,
reversible blades of long and narrow design features. Operating
speed is a cool, efficient 1,760 RPM. To improve performance standards,
Blastec®
engineers pioneered the concept of low RPM, direct drive between
motor and wheel. Horsepower robbing, high-maintenance items such
as spindle and pillow block bearings, sheaves, and V-belts have
been eliminated. This design assures maximum transmission of net
motor energy to the blade tips, optimizing shot velocity and pattern
efficiency.
The Blastec®
wheel is bi-directional, it is designed to rotate in either direction
(CW or CCW) at its full capacity in motor sizes ranging from 15-100
HP. The same wheel parts are employed regardless of rotational direction
or horsepower - so there is no need to stock different replacement
parts for different applications. Therefore, in multi-wheel facilities,
parts inventory requirements are greatly reduced.
 MAINTENANCE
The
Blastec®
wheel is specifically designed to simplify maintenance procedures.
The double sided runnerhead Is constructed of extremely durable
alloy steel. It is machined to exacting tolerances, heat treated,
and balanced to the toughest quality standards. Blades are easily
removed for replacement, or can be flipped end-for-end and reinstalled,
all through the top lid opening without the inconvenience of removing
the impeller, control cage or feed spout assembly. Side and end
liners can also be removed without disturbing any of the wheel’s
moving parts. As a result of this superior design, overall maintenance
time is significantly reduced.
RETROFITS
The Blastec®
wheel is the perfect candidate when considering upgrading your existing
shot blast machine. Each
Blastec®
wheel is shipped completely assembled. The industrial electric motor,
along with the steel housing and hinged lid are mounted to a Blastec®
heavy-duty base plate. Factory pre tested, the wheel is ready for
installation and operation with minimal setup. An installation drawingillustrating
the exact wheel location required for optimum performance is also
provided. Blastec®
offers installation and start-up assistance or complete turn-key
installation.
