Rockmore Launches The New
T Series DTH Hammer Class

Attendees of Wipware's 5th Annual Seminar.

Participants from Seven
Countries Across Four
Continents Joined Canadian
Attendees for WipWare's
5th Training Seminar
North Bay, Ontario, Canada-The soldout 5th Annual WipWare Training Seminar at the Canadian Ecology Centre in
Samuel de Champlain Provincial Park,
Sept. 16-19, drew positive reviews from
attendees from Australia, South Africa,
Netherlands, United Kingdom, Brazil,
Chile and the United States.
This year's pit-to-plant theme featured prominent speakers highlighting
the importance of fragmentation data
on both the blasting and processing
end of operations in addition to WipWare technical staff outlining software
features and automated system maintenance.
Guest speakers covered a range of
topics starting with an in-depth look at
various blasting parameters and some
exceptions to the kuz-ram model by the

renowned Dr. Calvin J. Konya, President
of Precision Blasting Services and Director of the Academy for Blasting and Explosives Technology.
Dr. Adrian Dance, principal metallurgy consultant at SRK Consulting Inc.
and a leading authority on mine-to-mill
optimization, outlined the justification
for increasing drill and blast costs to
achieve better fragmentation in terms of
cost savings downstream in the milling
operations.
Francois Robichaud, metallurgical superintendent at Agnico-Eagle, described
his experiences using image-based bulk
material particle-size-analyzers to evaluate crusher performance and monitor
SAG mill feed leading to optimized particle sizes entering their SAG mill resulting in higher throughput and reduced
energy costs.
Seminar participants also received
hands-on training with WipWare's WipFrag and Delta software packages, and
instruction on installation, use and maintenance of the company's Momentum,
Reflex and Solo automated systems.

Wilsonville, Oregon, USA-Rockmore
International has recently launched the T
series DTH hammer line and introduces
the first model in this class - the ROK
600T.
This new addition to Rockmore's existing broad range of DTH hammers is a
breakthrough for DTH drilling technology for mining, construction, and waterwell applications. In addition to its ultra
high performance features, the new T
series design hammers utilize drill bits
with standard shank connections that
no longer require plastic parts commonly
known as blow tubes or foot valves. The
elimination of this plastic part associated
with the drill bit offers various technical
and economical advantages.
"We recognized a trending demand
in the DTH drilling sector for a high performance DTH tool that could utilize industry standard drill bits without plastic
components in order to increase reliability yet not compromise drilling efficiency," comments Mr. Pejman Eghdami,
Executive Vice President of Rockmore
International.
The new T series DTH hammer design
is the result of extensive research, development, and field-testing. The T series
is "tubeless" and achieves the goal of
using industry bit shank connections,
but without the plastic component imbedded in the bit. Although the "tubeless" DTH hammer has been offered
before, drilling performance was often
compromised when designed to operate
with an industry standard bit shank. In
addition, other manufacturers have introduced DTH hammers that utilize bits
without a plastic component, but such
DTH bits are proprietary in design, which
limit their availability.
"With our emerging T class DTH
hammers, we are offering the drilling
community a balanced solution of improved reliability without compromising
any drilling performance. And impres-
