MINING BOLSTERS RH460 DTH HAMMER SERIES
Mining has added 6- and 8-inch models to its growing RH460 DTH
hammer family, designed to reduce costs, increase penetration rates
and prolong service life in even more drilling applications.
Mining is also introducing 4- and 5-inch RH460hp hammers,
air-efficient high-pressure models designed to operate at 32-35 bar
(450-500 psi). At 35 bar, RH460hp hammers consume less fuel and
cost less to operate than similar hammers at the same pressure.
The high-pressure hammers, an ideal match for DR500-series rigs and
the company’s new Pantera, feature the same benefits as all RH460
hammers.
The growing RH460 family optimizes the impact-energy transmission
in variable ground conditions. Enhanced air cycle improves
expansion and compression rates, producing more power while
reducing air and fuel consumption.
Developments in the piston design and improved lubrication
capabilities dramatically increase piston and hammer life across
the RH460 series. Mining has devoted much R&D work into
designing the bearing surfaces to ensure bending vibrations in the
piston are eliminated.
RH460 hammers also feature a unique V-lock mount system designed to
prevent movement of the internal components, ensuring reliability
and eliminating the need for shims and special assembly tools.
The working principle of the RH460 range ensures that the hammers
start up in any direction, making their design well-suited for all
surface and underground mining applications.
The design of the RH460 series makes the hammers easy to service.
The complete high-performance, cost-effective range is designed to
utilize bits with generic shank types.
ROSCHEN LAUNCHES LATEST IN RH460 DTH HAMMER SERIES
has launched a 4-inch hammer in its proven RH460 DTH series,
designed to reduce drilling costs, increase penetration rates and
prolong service life.
The growing RH460 family optimizes the impact-energy transmission
in variable ground conditions. Enhanced air cycle improves
expansion and compression rates, producing more power while
reducing air and fuel consumption.
Piston and hammer life are dramatically increased in the RH460
series, thanks to developments in the piston design and improved
lubrication capabilities.
