Combo Sand Washing Plant
Perfect sand. Each time. Every time: a fully integrated m-sand manufacturing plant with the power of mobile.
The CFlo Combo is a patented, fully integrated sand washing plant that produces washed M-Sand at 50–500 tonnes per hour on a single compact modular chassis. It combines feeding, washing, dewatering and stockpiling with water recycling that cuts fresh water demand by up to 95%, and is available in X70, Alpha, Multi and Turbo variants.
World-leading sand washing technology
Proven across hundreds of installations, CFlo sand washing technology helps customers maximise the quality and value of washed sand for construction, mining and industrial sand applications. The Combo takes that innovation and gives it the power of mobile: a compact plant that streamlines sand washing with unmatched efficiency and water management, on a minimal footprint.
The range covers 50 to 500 tonnes per hour across the Combo X70, Combo Alpha, Combo Multi and Combo Turbo variants. Every plant is Super modular by design: one integrated chassis that ships compactly and commissions fast, custom built for your specific project.
Inside the Combo
- Feed point efficiency: the feed hopper features an integrated belt feeder for efficient transfer of material to the next stage of processing
- Cut point efficiency: each patented Combo is custom built for your project, giving efficient control of silt cut points so washed sand meets your specification every time
- Superior sand dewatering: the Centriscreen Dewatering & Sizing System delivers washed sand that is ready for market straight from the belts, turning product into revenue as quickly as possible
- Unrivalled control of specification: integrated wing stockpiling conveyors controlled by a hydraulic cylinder let you make concrete sand and plaster sand at the same time
Use up to 95% less water
The Combo integrates CFlo's tried and tested water recycling technology, so you run the latest sand washing technology while reducing your water requirement by up to 95%. Our sludge management technology accelerates tailings drying for a smaller tailings footprint and returns recycled water to the plant much faster than other systems. Easysettle Sludge Bay Manager uses high performance polymer technology to rigidify tailings at the point of disposal, releasing water instantaneously from the treated slurry.
Safe access and automatic operation
There are no compromises on the Combo: you get the same walkway specification as a static processing plant, so your people have quick, easy and safe access for maintenance. The plant is Super smart too, with an on-board control panel in a double door stainless steel enclosure built for harsh outdoor environments, and a touch screen PLC as standard.
Proven in the field
GR Infraprojects runs a fleet of 11 Combo plants across its highway projects, relocating each in about 10 days and producing IS 383 compliant M-Sand at around Rs 550 a tonne against Rs 2,000 for natural sand. YTL Cement in Malaysia converts 0–5 mm crusher dust into 70 TPH of graded M-Sand with two Combo X70 plants at its Batu Tiga Quarry. And Zeal Alliance in Ratlam replaced a screw washer with a Combo X70 to produce consistent Zone II M-Sand with lower water use.
Frequently asked questions
What capacity does the Combo sand washing plant come in?
The Combo family spans 50 to 500 tonnes per hour, with X70, Alpha, Multi and Turbo variants. Each plant is custom built for your project and feed material, so the silt cut point and product gradation match your specification from day one rather than being tuned by trial and error on site.
How much water does a Combo sand washing plant use?
Up to 95% less than conventional washing. The Combo integrates CFlo's proven water recycling technology on the same chassis, and the Easysettle Sludge Bay Manager releases water from tailings instantaneously so recycled water returns to the plant faster than other systems. That also shrinks your tailings footprint and settling pond requirement.
Can the Combo make concrete sand and plaster sand at the same time?
Yes. Integrated wing stockpiling conveyors controlled by a hydraulic cylinder give you unrivalled control of sand specification, letting one Combo produce concrete sand and plaster sand simultaneously. The Centriscreen Dewatering & Sizing System delivers both products ready for market straight from the belts.
How much does M-Sand from a Combo cost to produce?
Production cost depends on your feed material, power cost and scale, but the benchmark is strong: GR Infraprojects produces IS 383 compliant M-Sand at around Rs 550 a tonne with its Combo fleet, against roughly Rs 2,000 a tonne for natural sand. Talk to us with your feed details for a project-specific number.
How is the Combo different from a bucket-wheel or screw washer?
Screw and bucket-wheel washers give you little control over the silt cut point, so fines and quality drift with the feed. The Combo controls the cut point precisely, dewaters sand to market-ready moisture straight off the belt, and recycles up to 95% of its water. Zeal Alliance replaced a screw washer with a Combo X70 for exactly this reason: consistent Zone II M-Sand.
How big is the footprint, and can it be relocated?
The Combo is a fully integrated mobile plant on a single compact chassis, so it needs a fraction of the space of a conventional wash plant and no civil-heavy installation. GR Infraprojects relocates its Combos between highway packages in about 10 days, which is the practical test of a genuinely modular plant.
