CFlo in the Middle East

Five platforms cover the range, and each has a page written for Gulf feeds, water constraints and site conditions. Every plant is factory assembled, ships in standard containers and commissions on a prepared pad rather than being built up on site.

• Combo: the sand washing plant, taking crushed rock fines, limestone scalpings and as-dug sand to washed concrete and plaster sand and clean graded aggregate at up to 350 tonnes per hour on one chassis, with up to 95% of process water recycled.
• Aerograder: the dry air classifier, cutting fines from a dry feed below 5 mm with no process water, no cyclones and no baghouse, proven on dune sand for proppant in Abu Dhabi.
• Micrograder: the specification plant for silica sand, grading frac, glass, foundry, filter and sports sand to a tight band with attrition scrubbing, precision screening and spiral gravity concentration.
• Oremax: the ore washing and beneficiation plant, lowering cut-off grades on low-grade minerals by scrubbing, wet screening and precise cut-point control.
• Reurban: the mobile plant that recycles construction and demolition waste on the site that generates it, removing trash and washing the feed into specification recycled sand and aggregate.

Two process modules come with every wet plant as standard. The Hydromax high-rate thickener returns the great majority of the process water to the plant, and the Easysettle sludge bay manager rigidifies tailings at the point of disposal so they dry to a trafficable cake without a pond. Plants for the Gulf are CE certified, with the PLC control panel CFlo designs and builds itself housed in a double-door stainless steel enclosure rated for outdoor use in harsh environments.

Dune sand is abundant, fine and dry. Wind sorting leaves it too fine and too uniform for a concrete grading envelope on its own, and over the 1% limit on minus 200 mesh (75 micron) fines for proppant. The correction is a bottom-end cut rather than a wash, and in the Gulf it has to be made without process water. The Aerograder makes the cut dry, with no process water, no cyclone and no baghouse, on feed below 5 mm at below 2% surface moisture, which an arid site provides year round.

Four Aerograder units in Abu Dhabi grade local dune sand into proppant for a major oil and gas services operator at 280 tonnes per hour combined. The July 2026 verification campaign, run at 70 tonnes per hour per unit, held the graded product at an average of 0.83% minus 200 mesh against the 1% ceiling, with mass yield of about 90% and roughly 94% of the plus 140 mesh fraction recovered, on no process water; the case study carries the full figures. Where the sand needs its coatings taken off as well, the Micrograder is the wet route.

The Oremax washes and beneficiates low-grade ore and recovers saleable product from tailings and slimes, and the same Hydromax and Easysettle modules that recycle water on a sand plant let a mining operation retire a pond. The Reurban recycles construction and demolition waste where it is generated, floating off wood, plastic and paper and washing the rubble into recycled sand and aggregate that sells against primary material. The regional reference is at Rawdat Rashed near Doha, where Green & Grey Trading and Contracting runs a CFlo recycling operation for QPMC: 310 tonnes per hour across two phases, one of the largest construction and demolition waste recycling installations in the Gulf, recycling 95% of its water with fines held below 3% in the finished aggregate.

No plant is engineered from a catalogue. Sizing starts with a Sample Study of your own material at CFlo's pilot plant and laboratory at Howrah, a DSIR-recognised in-house R&D unit: usually a review of your existing gradation data, then a 20 kg bench sample by courier, and a pilot sample only if the bench result justifies it. In the Gulf the report settles the question that decides the plant, whether the route is wet, dry or both, and gives the water balance alongside the grades and yields. Pre-Engineering follows only if the numbers work and runs in parallel with financial clearance, so manufacture starts when the supply contract is placed. The Sample Study page sets out the programme, the timings and how samples travel. Where capital is the constraint, CFlo also offers equipment leasing or pay-per-tonne tolling.

A representative sample or a recent gradation of the feed, a chemical analysis if you have one, the moisture as it arrives, the specification the product has to meet, the tonnes per hour you want to produce, and how much water the site has, because water decides whether the route is wet, dry or both. If sand is currently being trucked to your operation, the landed cost per tonne is useful too, because it is the number a local plant has to beat. Send it through the form above or contact CFlo World FZE, and we will scope the Sample Study with you before you ship anything.
