TECHNICAL SPECIFICATIONS FOR FLOW SORT TM
X-RAY DIAMOND RECOVERY MACHINE
These diamond recovery machines are designed to sort WET or DRY diamondiferous material and are built to be used under virtually any conditions.
Our sorters are built for permanent as well as mobile installations. Some are operating on river mining barges and others on marine diamond mining vessels!
Our sorter’s robustness, reliability, and simple operation, are all combined with high recovery efficiency and low maintenance costs. This is all backed by FLOW’S uncompromising after-sales service and thus has earned FLOW SORT products worldwide acceptance in the diamond mining industry.
Our FFXR 8/75 Bulk Sorter comprises 4 independent feed channels.
FEED CHANNELS CAN BE INDEPENDENTLY SET UP and CONTROLLED.
The sorter design allows a set of 2 channels being serviced whilst the other 2 channels remain fully in operation.
This feature REDUCES DOWNTIME FOR MAINTENANCE!
FFXR 8/75 DW Sorters are fitted with a FLOW SORT optical scanning system which was specifically designed to reduce yield and to enhance low luminescent diamond recovery efficiency.
FFXR 8/75 DW: 380 Volt (+- 10%), 50Hz, 3Phase
Power consumption approx. 8kVA.
Other Electrical Supply Specifications can be accommodated on request.
Flow Sort lightning and surge protection units, phase failure detection, and voltage stabilizer units, specifically designed and selected for FLOW SORT™ products, are available as optional extras.
QUALITY: Feed Water Supply must be filtered through a 100 Micron filter.
PRESSURE: Minimum: 400kpa Maximum: 800kpa
TEMPERATURE: MIN: +2.5°C MAX: +30°C
CONSUMPTION: Feed water consumption (flow Rate) depends on feed-rate, material size as well as the type of material to be sorted. Ranging from 30 l / min (typical) to 60 l/min
SORTER: MIN: +2.5°C MAX: +45°C REL. HUMIDITY: 95% (none condensing)
CONTROL PANEL: MIN: -5°C MAX: +45°C REL. HUMIDITY: 95% (none condensing)
FEED MATERIAL CAN BE WET OR DRY.
SORTER FEED MATERIAL MUST BE “CLEAN” ie FREE OF CLAY, SLIME, VEGETATION and FOREIGN OBJECTS
Minimum SIZE: Minimum size limit 6mm / Recommended Minimum 8mm
Maximum SIZE: recommended maximum 75mm
NO dimension may exceed 100mm
FEED MATERIAL MUST BE PRESENTED IN APPROPRIATE SIZE-RANGES, FREE OF UNDERSIZED and OVERSIZED MATERIAL.
PARTICLE SIZE RATIO: FLOW recommends not exceeding a particle size ratio of 3:1.
+ 8mm – 20mm, + 20mm – 32mm +32mm – 50mm, +50mm – 75mm
FLOW OFFERS A PROFESSIONAL CONSULTING SERVICE THAT WILL ADVISE ON OPTIMAL SIZE SPLITS APPLICABLE FOR SPECIFIC APPLICATIONS.
FEED RATE SPECIFICATIONS:
The feed rate of FLOW SORT MODEL FFXR 8/75 DW follows: FR = SC x d x s.g.
FR = FEED RATE in kg/hr
d = AVERAGE PARTICLE DIAMETER OF THE SIZE FRACTION BEING SORTED in mm
SC = “SORTER CONSTANT” This value varies with sorter configuration and application.
SC values for FFXR 8/75 BULK SORTERS are typically 1000, but vary with sorter application
SF = “SHAPE FACTOR” = average particle volume expressed as a portion of a sphere with diameter “d”.
If the average particle volume approx 60% of that of a sphere with the same diameter this value = 0,6
sg. = AVERAGE SPECIFIC GRAVITY OF FEED MATERIAL (g/cm3)
Each ejection will generate approximately 0,00024 % of the sorter’s federate FR (2,4 x 10-6 FR)
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.
The total luminescence emitted by a diamond by exposing it to X-ray radiation, varies most importantly with the X-ray exposure time, with its colour and transparency, impurities such as nitrogen, boron etc.
