John,

I saw one being demonstrated at Hillhead this year. They are available but can't off hand remember the manufacturer. I'm sure the organisers could help.

The thing I saw looked like a standard bucket but with a single toggle integral crusher built into it. It would fit onto any standard digger.

Could this be a link to your machine search?

Dear John Gateley

You where right about the design. It was an O&K development.

They even demonstrated the digging part by attaching a bucket, boom and stick from the RH 300 (hydraulic excavator) to an old bucket wheel excavator (if I remember right a 40 000 m3 per day machine of the Bayrische Braunkohlen Industrie AG in Schwandorf).

The installation was able to dig material up to approx. 30 m above ground.

The idea was to let it load into a crusher placed at the centre of the machine and carry on with conveyor transport from there on.

The concept was mainly meant for the US market to strip waste in coal mines, when the overburden was not suitable for BWE operation but continuous transport was intended.

(*The O&K RH 300 then almost doubled the existing bucket capacity. Since the population of then large trucks was too small and the machine had mechanical and maintenance problems it was not very successful. The today available unit RH 200 is a much more successful design. )

The idea died with low energy costs. A prototype was never build.

I like the idea, but it faces the difficulties the introduction of long lasting investment (conveyor/continuous systems) in a marked driven environment, where return of investment is asked for in years and not in decades.

Nice to know, that somebody else remembers, what was discussed some 25 years ago.

Two year old thread, but..

I think your describing something like:

I have had viewed most of the equipment listed by the respective post contributors, and I will add a couple of designs that I have worked on and I have a new one under wraps for face stripping >30metre face height and moving the overburden as in the MMD exercise at Goonyella/Riverside. My method reduces the 15 Kilometres of conveyor to the spoil dump to 300 metres. The 15 Km of conveyors takes the spoil / overburden at Goonyella / Riverside only 300 metres from the face. It is also restricted to only <25 metres face height stripping and the plant weighs in over 4000 tonnes not including the P&H XP4100 face shovel. The area of the equipment footprint is huge 120 long by 80 metres wide.

The present consulting under approval design is for a strip machine, at greater than 10,000 tonnes per hour, to replace 4 Cat D11s, 2 Komatsu 475 Superdozers, 2 Cat 45 ton excavators, Cat 992 - 994 Loaders and a fleet of 6 x 6 Cat and Volvo acticulated trucks. I will keep you posted on developments.

hi i am a mining engineer . i want to know how the input feeding i being done in this sytem. i also have a huge stock pile of ROM coal. Can i use this type of apron feeders to be fed through the dozer or rubble in the stockpile. i need a feed of very small quantitiy , say 10,000 tonnes per day. my input size of run of mine coal varies from 0 to 1500mm . please suggest. ■

The system is a belt, chain & slat type for clean operation. It can be dozer or loader fed but I have a self feeding hydraulic system that is an attachment that pulls the material into the inclined feeder ramp. The whole feeder / crusher is mobile and moves every few minutes into the ROM as it is exhausted, if it is in a long stockpile. The machine is designed to be moved at 1 - 4 K/h and weighs in at <80 Tonnes. The machine setup by-passes coal fines and crushes only the oversize. The primary crusher for your application 1500mm would be 54x84KRB and can be diesel or electric powered and is a single person remote controlled or cabin operated. The feeder can be a separated assembly but I have not done any just feeder supply but I would be prepared to if required.

The whole system is designed to be autonomous without loaders or other equipment except for haulout from the pit. Send me a pit layout & your current operations setup and I can quote you on a suitable setup for your needs to Les.Dunn@tamecservices.com.au . ■

Guys,

Here is a machine that I have been developing. Just now releasing it to the mining sector.

It's the world's first fully mobile truck dump station. Will handle ultra class trucks (400t) and produce up to 10,000mtph. This model uses a low speed sizer.

Absolutly no earth works involved (will save millions each move)

Can be used with a shiftable face conveyor and mobile hopper, just like a mobile shovel fed stations, but with the added flexibility of trucks.

Let me know what you think?

Hi Glenn, FDL are one a number of companies that I will be approaching in the next month or so when I have the final university results of my OneFits Roll conveyor idler roll. I also have the DunnEasy Idler assembly which has just been examined by the US Patents Office and zero objections were raised which left my patent attorney stunned as this in his first ever over a 40 year period that this has happened. 'Letters Patent' will be the next step for the DunnEasy around the world where it has been patented. The 'Letters Patent' for the OneFits Head & Roll will be sort in the continuance of time.

Both products offer large 'Carbon Footprint' & 'Environmental' savings. The OneFits in the preliminary testing according to the calculations from (Rio Tinto and Xstrata Mine) 2 engineers for full replacement of idler rolls will save, on their 25Km of conveyors each, at conservative estimates, over AUD$5,000 electrical power per 24 hours of operation. I will post the University "Tundra Testing" of Newcastle in New South Wales on the website.

These products are market available and to view them, please visit http://www.tamecservices.com.au. Let me know if you like the products. Tamec is looking to sell full 'Design, Manufacture, Market, Install' Licences for the applicable areas around the world for the Technology and I would be willing to sell the IP if the dollars are sound.

Look forward to hearing from all. ■
