True Temper Sports

True Temper Sports is the leading producer of golf shafts. Steel shafts are manufactured in
True Temper’s plant in Amory, Mississippi, which also manufactures bicycle frame components,
and steel products for the automotive and recreation industries.

True Temper’s steel golf shafts are the product of 41 individual manufacturing steps. Among the
most critical is polishing, a precisely controlled abrasive belt process which prepares the metal
for plating baths of duplex nickel, then chrome. These final steps are what give the shafts their
perfect, high-gloss shine.

As with all metal polishing operations, the safe and efficient collection of airborne particulate
is a key concern. In 2002, True Temper decided to replace one of several polishing process
dust collectors, which, due to internal corrosion and an increasing demand for maintenance,
had become obsolete. The company considered several alternatives, including both wet and
dry dust collection equipment.

True Temper chose a Whirl Wet Model MCD “(modular conveyor drag-out”) wet dust collection
system manufactured by Tri-Mer Corp.

More than 800 Whirl Wet systems are in operation, serving a broad range of metal grinding
and polishing operations, including those involving volatile materials such as titanium and
magnesium. Because the system is effective for the collection of all particulates one micron
and above, both soluble and insoluble, Whirl Wet dust collection systems are also used
throughout the food, chemical, and aggregate industries.

The Whirl Wet unit chosen by True Temper is mild steel, with stationary polypropylene impellers.
A corrosion-resistant liner protects mild steel wetted surfaces on the interior of the collector.
Because the Whirl Wet impellers are 100% polypropylene and resist the accumulation of the
collected material, corrosion in the impellers and blockage within the impellers is prevented.

Tri-Mer has systems serving similar applications that have demonstrated a 20-year service
life and longer. Whirl Wet units are manufactured in 100% polypropylene, 304 and 316 stainless,
FRP and PVC, in addition to mild steel.

Systems are supplied with one of three disposal options: manual, timed drain-down or, as was
the case with True Temper, Modular Conveyor Dragout (MCD). The latter is recommended for
heavy dust load applications, including grinding and polishing operations, because it allows
quick, easy removal of residue without shutting down the polishing operation – or even the
dust collector itself.

The Whirl Wet MCD at True Temper has operated continuously since its installation.
Beyond the advantages of efficient collection of polishing dusts and fines, the system has
also contributed to cleaner indoor air and simpler housekeeping, and is low-noise.

Requirements for system reliability and “zero unscheduled down-time” have been achieved.
High collection efficiency is maintained for lower emissions to atmosphere. Maintenance and
operating costs are low.
