Rock Drilling And Jaw Crusher Profile
Edited by Alan L. Hitchcox
Rock drilling
is all about power and speed. You need a lot of
power
to break into solid rock and high speed
to repeatedly hammer away at a
work site. For
safety and high productivity, many of today’s
machines
feature remote control. This presents
a challenge because the remote
control must be
easy to operate yet allow full functionality of
the
machine.
Top hammer percussive
drilling — the most common method for drilling
holes up to 140 mm diameter — hammers the rock
with impacts transferred
from the rock drill
to a drill bit in the bottom or a hole. Hydraulic
pressure generates the force required —
pressure builds to a maximum and
when
released, drives an impact piston forward. When
the piston strikes
a chuck, it transfers its
kinetic energy as a stress wave through a drill
rod to the drill bit, which uses this impact
energy to pulverize the rock.
Obtaining the
highest drilling productivity and economy requires
operation of all components in the system to
be highly synchronized.
Design criteria
When designing the hydraulic system for a rock
drill rig, the operator
must be given complete
and independent control of the key parameters —
percussion pressure, percussion frequency,
feed force, and rotation —
to achieve optimum
drilling efficiency. When all of these parameters
are
optimized to suit working conditions, the
drill bit has full contact with
the rock and
the shock wave captures maximum kinetic energy to
ensure that
each impact achieves high
productivity.
Although the design of
the machine itself accounts for much of the
machine’s productivity, achieving maximum
productivity to meet cost
targets requires a
well-engineered hydraulic system with components
that
can maintain high reliability even in the
face of frequent heavy impacts.
Furthermore, a
precise remote control is needed to achieve the
high
synchronization necessary for maximum
productivity. Remote control also
provides
higher visibility, controllability, and safety
than
machine-mounted controls. It also lends
itself to data acquisition to
monitor
operation and aid in improving future design of
machines.
Nimco Controls AB, Malmo, Sweden,
developed a system to meet these
criteria in
drill rigs manufactured by KG Mekaniska AB, Karl
Gustav,
Sweden. The electrohydraulic system
integrates the features of Nimco’s
Easy- Prog
CANbus-based remote-control system with its CV
2000 LS series
pressure-compensated valve. As
a result, drill rigs have produced optimal
results over the last two years.
The
electrohydraulic system consists of a variable-
displacement pump
with load sensing to improve
energy efficiency of the system, the CV 2000
LS pressure-compensated valve, and the
EasyProg CANbus system. Designers
also made an
effort to reduce the amount of hydraulic hose in
the machine.
Not surprisingly, then, the new
design contains about 13 less hose.
Component
details
The CV 2000 LS valve can accommodate a
flow of 125 lpm to each cylinder
port and is
designed to work with both fixed- and variable-
displacement
pumps. Work port flow is
controlled by 12- or 24-V proportional solenoids,
with manual hand lever override functions
available. Pressure limiters
can be fitted on
each individual work port together with shock
andor
anticavitation valves.
The EasyProg control is a PC-based system that
can be programmed in
modules; hardware can
also be built in modules to suit requirements of
the application. Its CANbus configuration
allows for digital and analog
inputs and
outputs. It features an easy-to-use menu for
entering all
settings and standard functions.
Automatic functions for drill rigs, for
example, enhance the speed of parameter
settings as well as ensure
specific safety
parameters.
The CV 2000 LS valve controls key
rock drill operating functions, such
as
percussion pressure and frequency, rotation
torque, and feed force.
It also controls track
drives, positioning, and a hydraulic fan drive.
The rock drill in action
To achieve the
best combination of productivity and economy, the
operator sets the percussion pressure and
frequency, and the control sets
rotational
speed according to set frequency. The final
setting is feed
force which is set against the
percussion pressure to position the drill
bit
close to the rock. These settings are all
maintained by the CV 2000
LS valve, which has
two compensators per spool section — one for each
cylinder port.
Hydraulic settings are made
via the EasyProg electrical remote
control
unit. Feed force is remotely controlled by the CV
2000 LS pressure
compensator through a pilot-
operated, electrically controlled
proportional
relief valve. This enables a continuous setting of
the feed
force while maintaining the
possibility of a second pressure limiter
working as an overpressure cutoff valve. The
design enables two pressure
limiters for one
cylinder port and extremely fine, stable pressure
control.
The valve’s compensators
exhibit flat flowpressure curves and
provide a
constant flow, regardless of load pressure. The
frequency and
rotation of the drill bit is
harmonized with the precise pressure setting
for the feed force. The PL-2000 pressure
limiter’s distinct pressure
cut-off point
ensures that the correct flow is maintained
throughout the
entire pressure range.
The
EasyProg drill rig version software has automatic
setting
functions to help the operator reduce
initial setup time. It also contains
maintenance and service frequency options that
can be accessed remotely
by OEMs through a GSM
unit that vcan be connected to any mobile phone.
Additional functions and portable remote
control units can be integrated
either by wire
or by Bluetooth, which, in the new version, has a
range
of 100 m.
Recently, we have talked
about rock drilling , the general mining
machinery. Of course, there is just a simple
talk. So that we have to
understand. Next, I
introduce a further, the mining machinery in the
other
a mechanical - jaw BR550JG-1 jaw
crusher — from Komatsu
America International
Co. —includes fully hydraulic tracked travel and
crushing systems. Powered by Komatsu's 306-hp
SAA6DI25E-2 engine, this
crusher has a
material-output range from 110 to 507 tons per
hour, with
adjustable open-side discharge
settings from apacities
make the machine
suitable for highway construction, housing
development,
and tunnel works, as well as
quarry, demolition, and excavation
applications.
The 52-ton self-propelled
crusher's high travel speeds (with a
maximum of approximately 2 mph), along
with its 25% gradeability, allow
efficient
relocation. And once relocated, it can maneuver
itself into
tight quarters and start to
operate immediately, processing a variety of
materials — including concrete debris and hard
rock.
The Komatsu designed and built 30- x
44-in., single-toggle jaw is
driven
hydraulically with a PC800 LSHT variable-
displacement motor via
a V-belt. Its speed
range — from 210 to 300 rpm — helps to adjust the
jaw to the materials to be crushed. The
closed-loop crusher control
incorporates
Komatsu's patented Hydraumind technology to
optimize
efficiency. Through a combination of
load-sensing and
pressure-compensated valves,
the HydrauMind hydraulic control and
monitoring system supplies the appropriate
flow of oil to each function.
Simultaneously,
it identifies potential overloads and
automatically
slows down the vibratory grizzly
infeed's gear-type motor before the
overloads
become a reality. A pressure dial on the control
can be set
for anticipated rock hardnesses to
work hand in hand with the Hydraumind
system.
The hydraulic design also allows the crusher to
start from a
stopped position, even when fully
loaded, and it has a reverse-rotation
function
to help remove bridged or plugged material from
the jaw chamber.
A 42-in. wide discharge
conveyor — driven by another LSHT piston-type
motor — carries material away from the jaw
chamber.
For more versatility, the crusher can
be operated from its on-board
control station
with hydraulic-excavator-type levers, or from
ground
level or the excavator or loader cab
via an optional radio remote control.
The
remote control operates all travel functions,
feeder onoff, jaw
onoff, engine auto
decelerate, emergency stop, and even the horn.
Above, we will rock drilling machine with jaw
