I dont want to re envent i want to make another one. ok?

But thank you for your information

Samplers range from legal assay equipment to scoops on the end of a log pole. If you are so cash strapped & the matter is urgent I suggest the latter is your only option.

If you design an automatic system in-house your will not be certified and the design period must be added to the procurement period, as well as the performance risks. Cutting a material stream is often dangerous, plenty of guarding & interlocking is involved, and your insurers???? will take you to the cleaners.

I thought copper prices were on the up slope recently. ■

No money + long purchase time = scoop on long pole

as louis has suggested.

Maybe carried out at a transfer chute to avoid damaging the belt. ■

Gentlemen

In this Forum, i think it is the best way, to talk to each other with respect.

Dear mr B.A

Feel free to send me a overview of your system, then i will give you some ideas.

It is simple fact that Google will provide a wealth of information for those who bother to use it.

"belt conveyor samplers" yields many references including on page 1 :

http://www.m-w.dk/division.asp?Name=jawo

http://www.au.sgs.com/homemechanica...psmssau.htm

http://www.eriez.com/resources/webpa...eltsampler.pdf

These pages include photographs and drawings, and can be used as the basis for a "do it yourself" design.

Those who make such systems commercially have the practical knowledge acquired over time and at cost to themselves. Clearly they should not be expected to to part with their knowledge and designs for NO COST, unless they have a desire to go out of business! ■

Dear mr Designer

This is a Forum for sharing knowledge.

If you not intend to share any knowledge with other company- that is fine.

Anyway we should all keep talking to each other with respect. ■

Suggesting contact outside the forum is hardly sharing knowledge within the forum. All too often the forums topics are befuddled by replies which imply the particular writer has trade secrets which he does not want the other forum members to see or, more importantly, comment on. What's to hide? When a website or manual is readily available & somebody persists in ignoring that source of information then either they don't understand the content or they are, to quote, trying to re-invent...These forums will always contain a degree of subjectivity because of the nature of the business they represent & forum members appreciate that. ■

Babak,

I notice you work for NICICO. Are you working at Kerman? I visited Sarcheshmeh in June 2005 to review your sampling systems and to provide a sampling presentation to your site engineers. At the time I was surprised at the lack of mechanical sampling equipment throughout the entire complex.

I'm sorry to see that the economic crisis has hit your operations. It is, however, very important that as the market slides productivity improvements, keeping costs to a minimum, safety and automation will be the way to maintain momentum for the mining industry. Correct and accurate representative sampling is a key component in maintaining process efficiencies.

Anyway, have a look at some of the videos on our web site. The Automated Sampling video is quite informative as are the sampler animations. This may provide you with an indication of what is required.

We would be happy to provide you with a quotation to supply a sampler to suit your operations. You may find the cost is not as expensive as you think. The capital cost could easily be recovered in productivity improvements.

Regards

Adam Nicholson

Babak,

Thanks for your reply.

We do not promote the use of cross belt (or hammer) samplers. Our engineering team strives to design samplers that meet or exceed international standards regarding good sampling practice.

We find it difficult to design a cross belt sampler that fully complies to these sampling standards. Such requirements as locating the cutter at a point which affords access to the complete material stream; avoiding spillage and/or throwing of the sample, and; minimal restriction of sample flow are difficult to achieve when using a cross belt sampler. It is important to meet these requirements to obtain an unbiased sample for analysis.

We are finding that our customers, especially those in the minerals and iron ore industries, prefer the use of cross stream (or falling stream) samplers. We find that this type of sampler better conforms to good sampling practices.

We engineer a range of linear cross stream samplers that can representatively sample up to 100mm particles at 16,000 tonnes per hour as well as rotary and arcual cross stream samplers (such as vezins) for smaller sampling applications.

Our experience shows that cross belt cutters are commonly used for sampling coal. They are generally cheaper than falling stream samplers, particularly when a cutter must be retrofitted.

If a company is going to invest in mechanical sampling devices then we feel it is best to supply a falling stream sampling system that best complies to sampling standards.

I'm not sure, however, if this will meet your requirements/budget?

If you can provide me your contact mailing address I would be happy to post you a copy of our sampling DVD and associated catalogue.

Regards

Adam Nicholson

Be aware that patent protection forbids the use of an invention, not just the manufacture & sale aspects. If there is patent content in the design/specification then you are sticking your neck out if something goes astray. You will not be indemnified against competitors of the device copied & worse; you will be totally responsible for any dismemberments or decapitations. Tell Ops to put up the proper money or do without. ■
