AFX Fusion Systems

2009-05-26T17:40:00.002-06:00

A robotic bead fusion system that has been scaled to meet the varying production demands of XRF laboratories.

The AFX4 system is based on the hugely successful 12 furnace fusion systems that, to date, have mass-produced millions of fused beads. This compact 4 furnace system better suits the requirements of the typical production laboratory.

It contains the same reliable components and the same proven methodology as the original high capacity systems that revolutionised large scale bead fusion preparation techniques. This technology is now accessible to a wider range of end users.

It is technology that distinctly surpasses any previous methodology and apparatus currently used in XRF laboratories around the world. It provides an efficient alternative from the low volume, manually demanding, batch processing methods currently adopted.

The AFX4 cell allows for manually filled crucibles to be introduced via a conveyor. The ADFX4 cell has the added benefit of automating the sample and flux dosing stage.

Linear Automation Systems

2009-05-26T17:38:00.005-06:00

Essa’s linear automation systems link high capacity sample preparation equipment with proven mechanical sampling devices using reliable sample transfer mechanisms.

Simply load your dried field sample into a crusher and collect the assay portion and pulp residue at the other end.

Linear automation systems offer many of the benefits associated with more flexible robot-based automation cells but at a fraction of the cost.

Greater consistency, improved traceability, better hazard management and insulation from labour availability and cost fluctuations are benefits from automating sample preparation processes.

These systems are specifically designed for medium throughput mineral laboratory sample preparation requirements. They are ideal for processing mineral ores such as gold, nickel and iron ore.

They are well suited for use at remote mining and exploration sites and do not require skilled labour to operate.

OEM Sample Preparation

2009-05-26T17:33:00.002-06:00

Tungsten Carbide Pulverising Mill Bowl

Tungsten carbide is the grinding head of choice for many laboratories where elemental contamination is limited to just two principal contaminants: tungsten and cobalt.

With the Essa 125cc grinding head all surfaces in contact with the sample (bowl, ring, roller and lid) are machined from tungsten carbide. The bowl chamber and inner lid layer are encased in stainless steel to increase overall strength and to reduce material cost.

The bowl and lid incorporate ergonomically-designed lifting flanges to enable easier handling when processing samples.

Chemical Composition:
Cobalt (Co): 6.0% by weight

Multiload & Multipour Systems

2009-05-26T17:25:00.002-06:00

Essa pioneered the development and engineering of the apparatus to facilitate multiple crucible loading and pouring in fire assay. The invention of both the multiloading and multipouring systems is one of the few innovations to benefit fire assay technology in recent times – a technique that has remained relatively unchanged for centuries.

Working closely in conjunction with fire assay operators the Essa multiloading and multipouring systems are practically designed, easy to operate and robust in construction.

These systems are specifically designed to suit your particular requirements and cater to such variables as crucible and cupel type, furnace manufacture and crucible layout configuration in the furnace.

XRF Press

2009-05-26T16:14:00.001-06:00

Essa Australia manufacture a bench mounted, two piece, high pressure, electro-hydraulic actuated press for laboratory use in the preparation of pressed powder samples for x-ray fluorescence analysis.

It is made up as a press unit and a separate 240 volt, single phase, electro-hydraulic power pack. The press unit is designed for free standing on the customer’s bench top with the separate power pack placed within a 3 metre hose length of the press unit. The most frequently used location for the power pack is the floor area beneath the press unit.

XRF Fusion Equipment

2009-05-26T16:11:00.001-06:00

Essa Australia has engineered a single furnace XRF bead fusion machine that has the flexibility of being operated manually or easily incorporated into an automated laboratory environment. Fusion time is 9 minutes with a total cycle time of approximately 10-12 minutes per sample. Castable crucibles can be used which means no pouring is required. If normal crucibles are used then the fused sample must be poured into a mould. This can be done manually or automated using a small industrial robot. It would be, therefore, most efficient to incorporate several furnaces serviced by a single robot.

XRD Press

2009-05-26T16:09:00.001-06:00

The Essa Australia XRD Press is designed to semi automate the preparation of pressed powder samples for analysis by XRD. The pneumatic piston forms a lightly pressed sample into a two piece sample holder associated with standard XRD analysers.

Barrick Automated Sample Preparation System

2009-05-22T16:43:00.001-06:00

ROCKLABS Automated Systems are based on the concept of a sample flowing through a process, not a series of batch events. The concept has been developed over the last fifteen years. Many new machines and devices have been invented by ROCKLABS Ltd to facilitate this concept.

The overall aim is simplicity of design and construction to minimise construction costs and running costs and enable the system to be operated by existing laboratory technicians and maintained by existing plant fitters.

All ROCKLABS Automated Systems are custom designed and built to meet the requirements of each laboratory. The layout will depend on sample details such as quantity, weight and type of sample to be processed per shift, the degree of automation and the building where the Automated System will be used as well as many other details.

To ensure success, there must be sufficient testing of a customer’s samples to determine the machines to be used and allow for possible changes in the future. e.g. sample weight may be increased.

Good teamwork is required. ROCKLABS’ staff and the customer’s staff must all work together to ensure the best outcome.

Automation allows for samples to be loaded as batches and the whole batch, up to 20 samples or more, processed with no operator involvement.

Over the last eight years ROCKLABS’ Automated Systems have processed many millions of samples, reducing laboratory costs and ensuring that high quality samples are ready for analysis.
Automation is a very big subject, so please contact ROCKLABS to discuss how ROCKLABS
Automated Systems can help your laboratory.

Price and delivery
As each System is custom built, prices can vary from USD100,000 to USD500,000. The price will include installation, training and Warranty. With every System, there is a need for a site visit, test work, design, building, shipping, installation, training etc. A minimum of six months must be allowed for each order of an Automated System.

Porgera Mechanised Sample Preparation System

2009-05-22T16:36:00.003-06:00

A Mechanised System is a combination of two or more machines and devices so that a process of sample preparation can be carried out without any operator action. Mechanised Systems are normally more complex than COMBOs or may have a different construction to a COMBO, e.g machines built in a tower layout, so a sample can travel vertically from one machine to another.

A Mechanised System has no automation so any changes of settings must be done manually by the operator. The machines and devices are turned on and left running until all the samples are processed. Samples are processed singly, they cannot be loaded as a batch of samples.

Mechanised Systems are designed to reduce operator lifting and handling to a minimum to reduce labour costs. They are normally supplied in a cabinet to reduce noise and allow dust extraction.

Mechanised Systems cost less than Automated Systems and are simpler, so the running cost is lower. They are ideal for laboratories processing 100 to 300 samples per day. Mechanised Systems have applications outside the laboratory e.g sampling stations, processing very large samples in a plant or mill.

Price and Delivery
Mechanised Systems cost USD50,000 to USD200,000. Discussions, testing, custom designs are all required so delivery time is approximately 3 - 6 months.

Smart Geo-Prep

2009-05-22T16:30:00.000-06:00

Rocklabs’ Smart Geo-Prep is an automated version of the very successful Boyd – RSD Combo. The automation is provided by an easy to use PLC.

When using Smart Geo-Prep the operator chooses an optimum weight for the split that will be produced. For example, when using a ring or puck mill, there is an optimum amount for pulverising, not too high a weight so the sample is pulverised fully, not too small a weight so the pulverised sample is representative of the original material.

The operator weighs each sample (this can be recorded in a LIM System) an loads it into the Boyd Crusher. The sample material falls into a small belt conveyor that takes it to the RSD.

The speed of the belt is controlled by a PLC so that small samples travel slowly, to ensure a high quality split through the RSD. The RSD is controlled by the PLC to provide the pre-set weigh plus the remainder. The remainder can be retained or dumped. If dumped, it can be removed by a second belt conveyor to a bin or outside the building.

CRM – RSD Combo

2009-05-22T16:27:00.001-06:00

Features

Highly efficient.
Pulverising and splitting in one operation
Coarse/Fine pulverising
Two splits only – sample and remainder. Splitting segments are available.
Large sample collector for up to 10kg
Air ducting built in for dust extraction and Head cleaning
Safety switches built in

In a COMBO, two machines to devices are inter-connected so a samples goes through both as one process.

The best example is Rocklabs Boyd-RSD Combo. In this combo, a sample is loaded into a Boyd Crusher. The crushed material falls into a vibrating feeder or onto a conveyor belt, which transport it to an RSD standing alongside the Boyd Crusher. The RSD splits out a portion for pulverising.

COMBOs reduce handling, increase sample output, improve sample quality and reduce costs.

COMBOs are not automated. Settings such as split percentage can be changed manually.

COMBOs are produced in small batches to minimise cost, but there can be some modifications to suit each installation. For example, a Boyd-RSD Combo normally has the RSD on the right of the Boyd but this can be reversed.

The price range of COMBOs is approximately USD10,000 to USD50,000.
