CEMCO Turbo 80 VSI Crusher

CEMCO, Inc. (CEMCO) Vertical Shaft Impact (VSI) Crusher Increases Production
at Metroplex Sand & Gravel’s Fort Worth, TX Plant by 55%

Metroplex Sand & Gravel produces C-133 concrete sand and C-144 masonry sand by
crushing river rock feed material. Since Metroplex’s January, 2008 installation of
a CEMCO Turbo 80 VSI Crusher, the plant has increased production of C-133
concrete sand by an estimated 55% according to Keith Newell, President and
Chief Operating Officer.

“In addition to the increased production, Metroplex
Sand & Gravel is now able to use the new CEMCO VSI Crusher to process reserves
into a product that could potentially sell at a higher price than C-133 sand,”
said Mr. Newell. “The CEMCO VSI Crusher has dramatically increased our
production and value thereof, while also adding years to our base of available
reserves. This has all been achieved at a cost per ton which I feel is quite
low given the overall benefits of the machine. From the initial setup of our
crusher, to programming the drive, to days of on-site support (and hours of
off-site support over the phone), you (CEMCO) have taken product support to a
level that I believe to be unprecedented in this industry.”

“Integrating a programmable Siemens Variable Frequency Drive (VFD) with
the CEMCO Turbo 80 creates a versatile material processing machine that will
save Metroplex about 25% per KW hour used. The annual dollars saved on
electricity alone pays for the new crusher,” said Mike Neal, CEMCO’s National
Sales Manager.

“We are pleased to have been able to deliver a tool capable of delivering
this level of productive output. We believe that Metroplex will realize
considerable benefit from their purchase of the Turbo 80,” said Neil Hise,
CEMCO’s president. “We believe that CEMCO’s line of turbo VSI Crushers are
the most productive, most reliable and most cost effective VSI Crushers in the
market. Feedback like this from our customers is why we pride ourselves in
providing the best service in the industry.”

CEMCO, a 45 year old industrial equipment manufacturing company, has a
world renowned line of VSI Crushers. Out of the nine (9) crusher models that
CEMCO manufactures, the Turbo 80 is its mid-size model. The Turbo 80 can be
equipped to operate between 100-275 TPH with a max feed size of 2.5″ material.
CEMCO VSI Crushers are designed to make the components that require routine
maintenance easily accessible. Major servicing of the CEMCO VSI can be done
in less than an hour, reducing the plants “down time” and lowering overall
operating cost. The drive system of all CEMCO VSI Crushers uses a filtered
oil lubrication system that greatly increases the life of the crusher.
