LAS402 4 Stage Linear Automated Sample Preparation System
A Simple, Robust and Cost EffectiveAutomation Solution

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.
