COMPARISON

Summary of sorter selection/comparison criteria:

1. When buying an x-ray diamond recovery machine make sure that you get advice from a leading expert in this highly specialized field. 
2. Carefully check the track record of the company from which you consider buying your sorter. How many sorters, of the SAME MODEL you are offering to purchase, are currently operating in the field? What service backup etc can you expect? Check references! FLOW SORT has been in business for over 30 years! There are currently over 430 FLOW SORT machines in the field! Check our credentials with any of our customers.
3. When comparing the purchase prices of different makes of x-ray diamond recovery machines add the cost for all ‘auxiliary’ equipment that you need to operate this sorter to the actual sorter cost. (Compressor, air dryer, x-ray cooling water chiller, feed material dryer, etc.) For a FLOW SORT machine, you need NO ‘auxiliary’ equipment whatsoever, so there is NO extra cost involved!
4. When comparing the operating costs of different makes of x-ray diamond recovery machines make sure that you add in the operating cost of ALL ‘extra’ equipment that you need to operate with your sorter! With a FLOW SORT machine, there are NO EXTRAS!
5. How easy is it to operate and maintain the sorter you are considering buying? FLOW SORT machines are of modular construction, designed for rough handling, simple operating and easy Don’t service or repair on site; utilize FLOW’S exchange unit service!
6. Make sure that you get a written through-put guarantee, without any qualifications! FLOW SORT does guarantee the quoted (specified) throughput of its sorters without any “IF‟s” and “BUT‟s”!
7. Make sure that you get YOUR diamonds and YOUR feed material expertly tested before you purchase any x-ray-based diamond recovery FLOW SORT offers an analysis service to all its potential customers at no cost!
8. Recovery of diamonds from wet feed material is most definitely preferable to the recovery of diamonds from dry feed material for the simple reason that feed preparation processes prior to x-ray diamond recovery are wet processes! FLOW SORT machines are designed to sort wet material, even in seawater is acceptable. FLOW SORT machines obviously can also sort dry feed It is however not surprising that so far no one has ever taken up this option!
9. FLOW SORT’S mechanical ejector has many advantages compared to traditional air ejectors. For a wet feed x-ray diamond recovery machine it is a must! Further, note that FLOW SORT mechanical ejectors do not generate more yield than their pneumatic counterparts.
