Crushing and screening is at the heart of any mining operation and any improvements made in this area reflect positively on the bottom line.

ALLU Transformer D and M-Series attachment buckets are entirely driven by the hydraulics of the carrier machine and were designed to deliver a one-step screening and loading solution capable of handling all materials from wet soils to coal and rock.

The M series was developed specifically for the mining industry and has attachments to suit 50-160 tonne excavators and 30-90 tonne wheel loaders.

The D-series was designed for use in soft rock quarries, handling of sand and gravel aggregates, material loading at ports, de-clumping of hardened materials and processing of green waste and compost materials.

When looking at ALLU case study projects with an holistic approach – given multiple equipment mobilisations – fuel costs and the cost to process in low margin return ore or reclaiming projects have shown between $1.50-$2.50/t savings in running costs, in comparison to multiple unit processing configurations.

Custom configuration

The buckets can be fitted to either excavators or wheel loaders and instantly converts them into a mobile primary screening and loading plant.

Depending on the model, each bucket is fitted with three or four shafts, which are chain-driven by the on-board, 1400cc heavy-duty, hydraulic motor – powered by the carrier’s hydraulic pressure.  These shafts either feature a hammer mill profile for impact crushing and screening or a cam lobe design for screening.

A range of blade and drum sizes are available to provide fragment sizes of 50mm, 75mm, 100mm and 150mm.

Each application is different, so by interchanging drums, the bucket can be configured for optimal undersize and oversize to meet the needs of a particular site.

Built tough to suit these harsh environments, the frame of each Transformer bucket is made from 100pc wear-resistant steel and utilises genuine CAT ground engagement tools, ensuring that replacement teeth can be sourced anywhere in the world.  All blades, hammers and bars are hard-metal coated for added durability.

Single step operation

As the Transformer bucket begins processing, the undersize material falls through the bottom screen and can be tipped directly into a truck or processing plant.

The oversize remains in the bucket and can be tipped onto a stock pile or conveyor.

In terms of crushing power, the ALLU buckets can  process material rated between 1 and 4 on the MOH scale.

This typically includes coal, gypsum, dolomite, limestone, sandstone, shale and talc.  An added bonus is the bucket’s ability to handle wet material without clogging, which is often a serious challenge in clay-bound areas.

Machine to material

Apart from their diversity, Transformer buckets offer the most portable processing solution available – they allow the machine to go to the pile, the pile no longer needs to be hauled to the machine.  This creates significant transport cost savings as haul trucks are not required to bring material to the processing plant and there is no need for an additional excavator to load the hauled material into a fixed crusher.

Such mobility also permits a machine fitted with the Transformer attachment to be quickly and easily transported via low-loader to a satellite location, or even a different site, where it can be put into production immediately.

Again, this eliminates the necessity for a separate remote plant and associated wiring and infrastructure.

Data acquisition

Processing data is of huge value to production and financial personnel and the M-Series buckets tick that box too.

Using ALLU’s proprietary ALLU-DARE data recording system, information such as processed tonnes, bucket count, processing time, total working time, down time, cycle time and even hydraulic temperature can be recorded and viewed via the web app.

This allows the actual throughput of the attachment to be monitored, recorded and included in production schedules, new project quotes and when estimating project finish times, just as it would be from a fixed plant.

Australia-wide

ALLU Transformer buckets are distributed to more than 30 countries around the world and are now available across Australia.

RD Williams is the Australian importer of the ALLU buckets, and has partnered with an experienced network of successful businesses which ensures that all sales, parts and servicing of the Transformer attachments is taken care of by a dedicated dealer in each state.

The network includes: Walkers Hammers (Victoria); Groundtec (NSW); QLD Rock Breakers (QRB) (Qld and NT); Total Rockbreaking Solutions (TRS) (WA); RAM Equipment (SA); and DLM Machinery (Tasmania).

ALLU’s Transformer attachments provide processing and handling solutions for a number of industries.

Nick Angus from QRB said their unique design delivers increased efficiency and productivity on site, capex savings by eliminating the need for remote processing plants, transport savings with only a low-loader required to move the carrier from location to location and reduced operating expenses from the ‘one operator, one machine, one attachment’ philosophy.

Finlay Screening and Crushing Systems offers a range of jaw crushers, impact crushers and cone crushers to suit a range of mining applications, from coal to gold, and everything in between.

The Terex Finlay J-1480 jaw crusher

Jaw crushers effectively break down materials such as granite, limestone, concrete and asphalt, and Finlay’s machines include a powerful combination of performance, simplicity and versatility combined to suit almost any application.

The J-1480 single toggle Jaw Crusher is fitted with a Terex Jaques 1370mm x 762mm (54” x 30”) single toggle jaw crusher chamber and a heavy-duty undercarriage for exceptional on-site mobility.

The hydrostatic drive, independent hydraulic pre-screen, heavy duty vibrating feeder, with automatic control to regulate the feed into the crusher, ensures that the machine delivers maximum performance and efficiency, reducing down time whatever the application.

Selectable discharge of fines materials to either the by-pass or main conveyor and reversible operation for clearing blockages are features of this machine.

Finlay Screening and Crushing Systems manager Ronnie Bustard said the J1480 enabled a coal mine to maximise throughput on their plant to about 400 tonnes per hour.

“This machine can actually ramp up to 750 tonnes per hour depending on the size its crushing and the feed size going into it,” he said.

“On this particular site it’s a bit slower because the coal being crushed is quite large, however the J-1480 is more than capable of taking the bigger feed size and, unlike smaller crushers, is less likely to become blocked as a result.”

Operators can also choose to collect product via the bypass conveyor, or discharge the product via the main conveyor and the integrated pre-screen system removes fines and sizes before entering the jaw chamber, reducing packing and wear on the jaw liners.

“The customer didn’t want to generate fines, so the bypass feature with the pre-screen helps and you can generate less fines than you would with an impactor or cone crusher,” Mr Bustard said.

The I140RS impact crusher

Finlay stocks a range of high quality mobile impact crushers that use a combination of unique crushing variations to provide low wear costs, superior materials and high reduction ratios.

The Terex Finlay I-140RS shapes the future through innovation, with advanced technological design resulting in improved material flow and production capabilities in quarrying, mining, demolition and recycling applications.

Incorporating the Terex CR032 impact chamber with direct drive and an advanced electronic control system, the machine provides operators with high material reduction ratios and produces a consistent product shape.

A key component of the machine is the on-board innovative quick detach 4.8m x 1.5m (16’ x 5’) single deck screen.

For applications not requiring recirculation of materials for further processing or stockpiling, the complete screening and recirculating system can be quickly detached from the machine.

The high productivity, ease of maintenance and operation makes the machine an ideal solution for large scale producers and contract crushing operators.

Mr Bustard said the I-140RS had a range of features, including the ease of material flow through the machine being greatly improved with each component increasing in width as the material moves through the machine; fully hydraulic assisted apron setting features, making adjustment of the aprons convenient; and efficient and a heavy duty vibrating grizzly feeder (VGF) with integral pre-screen, removing dirt fines and sizes bypass material for reprocessing.

“Throughput on this machine is around 450 tonnes per hour,” he said.

“As opposed to our jaw crushers, the impactor means you can crush down to smaller sizes as it’s adjustable to suit different requirements.

“For our coal client we ran the machines with independent pre-screens – again bypassing a lot of the inspec material, which does two things; one, cuts down the load on your rotor which increases throughput, and two, it means you’re not crushing inspec material.”

The I-140 RS also has a quick on-board detachable recirculating system, including large 4.8m x 1.5m (16’ x 5’) single deck screen as well as a recirculating conveyor which can be rotated from closed loop configuration or utilised for stockpiling making an additional oversized product.

“The variable speed of the rotor also determines how hard you hit the coal and that again determines how much plus the recirculating conveyor on this machine can be slewed out to stockpile position for coal with high ash contamination,” Mr Bustard said.

“You will lose a little coal by stockpiling that material rather than putting it back into the chamber but your ash content comes down and that’s worth doing.

“Like in the gold process, it’s worth sacrificing a little bit than putting it back in and wasting time, contaminating it and bring it down to a low value.”

C1550 P and C1540 cone crushers

Terex Finlay cone crushers are ideal for the aggregate and mineral processing industries.

These cone crushers have been effectively designed to only break down the materials that need to be crushed, in order to increase the capacity of the machine and greatly reduce running costs.

Finlay’s cone crushing equipment includes innovative features such as hydrostatic drive, rapid set up time, chamber clearing, high reductions ratio, high output capacity and advanced electronic control systems.

The Terex Finlay C-1550P leads the way, incorporating the proven Terex 1300 cone crusher driven through direct drive.

The machine features a patent pending optional pre-screen module with a single deck 2.45m x 1.52m (8’ x 5’) screen for removal or bypass of fines from the feed material.

The integrated chute system, below the pre-screen, allows the fines material to be discharged from the machine using the optional by-pass conveyor or reintroduced onto the main product conveyor.

Both methods improve the overall plant throughput capacity, product flexibility and liner wear reduction.

The cone features variable speed drive, hydraulic tramp relief system and ability to change closed side setting while crushing.

The large hopper/feeder has an automated metal detection and a purge system to protect the cone and reduce downtime by removing metal contaminants via the purge chute.

The hydraulically adjustable feed conveyor allows the machine to be operated using either the innovative pre-screen system, or, if required, by feeding directly into the cone.

Comparatively, the C-1540 cone crushing equipment features a number of major benefits including hydrostatic drive, rapid set-up time, high reduction ratio, high output capacity and advanced electronic control system with an integrated pre-screen feature.

By only crushing the products that need to be crushed, the capacity of the machine is increased and wear costs reduced.

The metal detector on the hopper with self-clearing facility is also another notable feature.

With an automatic tramp metal relief, hydraulically adjustable closed side settings, ease of maintenance and direct hydrostatic drive, the Cone chamber is already well established in the marketplace.

Mr Bustard said the use of the J-1480 Jaw Crusher, along with both the C-1550P and C-1540 cone crushers, is an effective combination for gold miners.

“With a client making a 14mm minus for their ball mill (which is an extremely hard and abrasive material), we put it through the J-1480 jaw crusher, then into the C-1550P cone crusher with a pre-screen of 14mm to bypass the inspect material from the chamber,” he said.

“Oversize plus 14mm passed through the chamber, and crushed down to approximately 35mm minus, which then goes on to a screening plant.

“The oversize (+14mm -35mm) from the screening plant goes out into a C1540 cone crusher which is smaller (the C1550P is a 1300mm cone and the C1540 is a 1000 mm cone in comparison) is fed back onto the screen so that all inspect material 14mm minus on the ground goes straight to the ball mill.”

The post Crushing the competition appeared first on The Australian Mining Review.

While the company offers a wide range of services, from bulk material handling to air cannons and magnets, it specialises in the design and construction of ore screens, and has been selling them throughout Australia and to all corners of the globe since Mel King expanded Minspec to form OreFlow in 2013.

With a team of 16 on board, OreFlow has the capacity to do the big jobs, and the agility of a small team of experts to create a tailored, personal experience.

The team is small enough to be nimble, but big enough to do the heavy lifting and get the job done.

OreFlow Technical Specialist Mel King said that “we quote it, we draft it, we build it to a certain stage, and then if it gets too big, we sub contract it to an engineering company, but we will do QA from start to finish”.

“Everything is drawn in-house, it’s engineered in-house, our springs are made locally, we are an Australian company and our customers love that about us.”

Whether a customer needs a Trommel screen for waste processing, or a vibrating screen for materials separation. Oreflow can provide the right screen type, and the right screen size, to achieve the outcomes and aims required.

The company understands that to get it right when it comes to material size, conforming to a rigid specification relies heavily on using the appropriate screen size.

Different materials have different separation rates, and this is why it is important that the correct screen size is used, as it will maximise the efficacy and efficiency of the screen.

For this reason, OreFlow’s engineering team optimises the design of all its equipment using JKTech simulation software.

Oreflow works with local Australian providers who continue to offer the highest quality components at competitive prices, along with the face-to-face relationships that are at the core of its success.

“We have established relationships that are very strong and provide us first class service. We get approached everyday by people who want us to use their products, but we don’t need to when what we’ve got works so well” Mr King said.

“Our providers are loyal, consistent and we always get good pricing so why would we want to change that.”

Oreflow’s timely well-built machines have been used across Australia and all over the world, and Mr King said that there was a lot of international interest around OreFlow’s products.

“We are Australian and we work for Australians and we are Australian-owned and operated, but we export worldwide,” he said.

“We have sent screens to Africa, to Asia – Indonesia and PNG – and we have a lot of interest from Europe.

Oreflow’s strength comes from its business model which is centred around the customers it serves and the close relationships it builds with suppliers.

“We do anything to do with moving material from one point to another” Mr King said.

“We operate small because we want to stay nimble, lean and effective – it works for us.”

Oreflow is the Australian master distributor for the Brelko range of spillage control products, which have quickly gained acceptance in the Australian market place.

It is a major supplier of skirting systems, belt scrapers, air cannons and impact beds both locally and overseas.

The company’s conveyor, belt and apron feeder design and manufacture are becoming internationally renowned.

Oreflow also imports its own range of conveyor idlers and frames, which are readily interchangeable with Australian manufactured products without modification.

The company has exported crushers, screens, feeders, belt scrapers and idlers overseas to various countries including Ghana, Senegal, Burkina Faso, Mali, Tanzania, Indonesia, Philippines, Saudi Arabia and Zambia as well as many local iron ore, gold, nickel and mineral sands projects.

The Oreflow service team are also multi-skilled in elevated work platforms, Franna cranes and rigging, thus reducing waiting time on jobs.
