FLSmidth’s linear automation systems link high capacitysample
preparation equipment with proven mechanicalsampling devices using
reliable sample transfermechanisms.
Simply load your dried field sample into a crusher andcollect the
assay portion at the other end.
Linear automation systems offer many of the benefitsassociated with
more flexible robot-based automationcells but at a fraction of the
cost.
Greater consistency, improved traceability, better
hazardmanagement, increased throughput and insulation fromlabour
availability and cost fluctuations are benefits fromautomating
sample preparation processes.
These systems are specifically designed for mediumthroughput
mineral laboratory sample preparationrequirements. They are ideal
for processing mineral oressuch as gold, nickel and iron ore.
They are well suited for use at remote mining andexploration sites,
in transportable laboratories and do notrequire skilled labour to
operate.
System Features
Up to 10 kg of lump ore can be fed into the system
Rapid crushing to 2 mm from 110 mm prior todividing
System output of 75 micron with selectable pulpweight and number of
collected portions
Coarse reject either collected or discarded via optionalreject
conveyor
In built air blast cleaning minimises contaminationSmall footprint
Readily transportable and ideal for remote locationwork
Simple and fast installation
Manual handling of samples greatly reduced
Less risk of human error - skilled labour not needed
Designed for easy maintenance as major equipmentitems positioned at
floor level
Modular design incorporating proven Essaequipment
Description and Capabilities
The LAS402 linear automation system includes an EssaModel JC2501
Jaw Crusher, an Essa RTS034V variablesplit rotary tube sampler and
a fine pulverising EssaABM200R Autobatch Mill with an in-built
rotary divider.An in-feed load cell is also supplied as standard.
Thesystem’s PLC determines the appropriate coarse splitratio based
on initial sample mass to ensure the requiredsample weight for fine
pulverising.
The JC2501 accepts lump ore and core up to 110 mmand produces a
fine crushed material, 85% passing2 mm, suitable for division and
pulverising.
The crusher features a simple self feeding mechanism.This prevents
the crusher being choke fed with an excessof fine or compactable
material that may overstress thecrusher. In addition, it completely
prevents operatorexposure to the crushing chamber whilst sample is
beingcrushed.
The variable split rotary tube sampler delivers a coarsesplit of
between 5% and 48% of 2 mm material.
Coarse material reject from the sampler is dischargeddirectly from
the side of the ABM200R cabinet. If thereject is not be collected
then it is recommended that it isremoved via a reject conveyor.
The ever reliable ABM200R mill, fitted with a 2000 ccbowl,
pulverises up to 1.2 kg to 75 micron. Typically800 g is selected.
The rotary divider after the ABM200R divides the sampleto
selectable portions. This is done by placing one ormore segments
into a standard rotary sample divider.A trouble-free bucket lifter
moves samples from thecrusher to the rotary tube sampler keeping
all majorequipment items on ground level for easy maintenance.The
bucket lifting system includes an air blast cleaningstation, with
dust extraction point, for keeping the bucketfree of residual
sample material.
The RTS034V and ABM200R both incorporate in-built airblast clean
and dust removal systems to minimise samplecross-contamination.
Method of Operation
The system is controlled by a single operator weighing andfeeding
samples at the in-feed point.
Typically samples are crushed to 2 mm and then fed to theRTS034V, a
coarse split of 800 g is taken and introducedto the ABM200R where
it is pulverised to 75 micron beforebeing fine split to
configurable segments.
Up to three samples are processed in the system at anyone time.
Skilled labour is not required to operate this system.
Typical Throughput
If crushing 2 kg to 10 kg of sample and fine pulverisingnominally
0.8kg you can achieve up to a maximum of ten(10) prepared samples
per hour.
