TECHNICAL SPECIFICATIONS FOR FLOW SORT TM
X-RAY DIAMOND RECOVERY MACHINE
This diamond recovery machine, specifically designed to sort WET or DRY diamondiferous material, under virtually any conditions, is the “work-horse” in the FLOW SORT sorting machine stable.
Within 14 years of the sorter’s launch, we have sold some 500 units to diamond mines all over the world.
Our sorters are suitable for “fixed” installations and “mobile” installations as well as on board of “marine” diamond-mining vessels.
It is our sorter’s robustness, reliability, high recovery efficiency, easy operation and low maintenance, as well as our uncompromising after-sales service that earned the acceptance of our products in the marketplace.
We offer our sorters in two basic models. SINGLE STAGE MODELS coded as XR 2/50 DW and
TWIN-STAGE MODELS (double pass sorters) referred to as TSXR 2/50 DW.
Both XR and TSXR sorters are available as a standard (STD) as well as marine (SEA) versions.
Both diamond recovery machine models can also be supplied (Configured) as re-concentration sorters
(REC) designed to treat the concentrate of several primary sorter models.
Standard XR: 380 Volt (+/- 10%), 50 Hz, 3 Phase + Neutral, + Earth.
Power consumption approx. 3kVA.
Standard TSXR: 380 Volt (+/- 10%), 50 Hz, 3 Phase + Neutral, + Earth.
Power consumption approx. 4kVA.
Other Electrical Supply Specifications can be accommodated on request.
As optional extras Flow Sort also supplies lightning protection, surge and phase failure protection, as well as voltage stabilizer units.
QUALITY: Water supply must be filtered through a 100 Micron filter.
PRESSURE: Water supply pressure must not be less than 400 kPa and not exceed 800kPa.
TEMPERATURE: MIN: +2.5°C MAX: +30°C
Volume XR-: Typically 15 litres/min. Water flow rate (volume) however varies depending on feed rate, material size and type of material to be sorted.
Volume TSXR-: Typically 25 litres/min. Water flow rate (volume) however varies depending on feed rate, material size and type of material to be sorted.
SORTER: MIN: +2.5°C MAX: +45°C
RELATIVE HUMIDITY: 95% non-condensing
CONTROL PANEL: MIN: -5°C MAX: +45°C
RELATIVE HUMIDITY: 95% non-condensing
Min SIZE for XR- & TSXR- 2/50DW: There is no minimum size limit! The recommended minimum is 2mm.
Max SIZE for XR- & TSXR- 2/50DW: Recommended maximum is 42mm. Maximum is 50mm
(No particle may exceed 50 mm in any dimension)
For maximum recovery efficiency, we recommend a size ratio of 2:1 for material below 4mm and up to 3:1 for material above 3mm.
FLOW SORT OFFERS A PROFESSIONAL CONSULTING SERVICE TO ADVISE ON OPTIMAL SIZE SPLITS FOR SPECIFIC APPLICATIONS.
4 fractions: + 2mm – 4mm, + 4mm – 10mm, + 10mm – 22mm, + 22mm – 42mm
3 fractions: +2mm – 5mm, +5mm – 12mm, +12mm – 32mm
FEED MATERIAL CAN BE WET OR DRY. IMPORTANT IS THAT THE MATERIAL IS “CLEAN” i.e. FREE OF CLAY, SLIME, VEGETATION OR OTHER FOREIGN OBJECTS.
FEED MATERIAL MUST BE PRESENTED IN APPROPRIATE SIZE RANGES AND FREE OF UNDERSIZED AS WELL AS OVERSIZED MATERIAL.
FLOW SORT SUPPLIES HIGH-SECURITY SELF-LOCKING CONCENTRATE BINS, DESIGNED TO FIT DIRECTLY ONTO A SORTER’S CONCENTRATE OUTLET.
SORTER MODELS XR-2/50 DW & TSXR-2/50 DW and
RE-CON MODELS XR-2/50 DW-rec & TSXR-2/50 DW-rec
Sorter feed rates “FR”,in kg/hr, are computed by using the following formulae:
FR (kg/h) = SC x d(mm) x SF x sg.
d = AVERAGE PARTICLE DIAMETER (WITHIN A GIVEN SIZE FRACTION) in mm
SC = “SORTER CONSTANT” This value varies with sorter configuration and application. SC values for primary recovery applications vary from 150 to 600 and for concentration applications (REC sorter version) from 15 to 25.
SF = “SHAPE FACTOR” = the particle volume expressed as a portion of the volume of a sphere with “d”. (a particle with 60% of the volume of a sphere of diameter “d” results in a “SHAPE FACTOR” = 0.6)
sg. = AVERAGE SPECIFIC GRAVITY OF FEED MATERIAL (g/cm3)
Diamond recovery efficiency is influenced by many factors such as feed rate, feed material particle size ratio, feed material temperature, feed material contamination with fines and dirt, and so on.
Diamond detectability based on X-ray luminescence varies with a diamond’s colour,
impurities, level of transparency, nitrogen content etc.
FLOW SORT has developed technology that is capable of detecting the most faintly luminescent diamonds under the most difficult of circumstances!
