What the batching plant enforces
- Gradation envelope: concrete sand must sit within the specified sieve curve — too fine and water demand spikes, too coarse and workability dies.
- Fines content: material passing 75 μm is limited; clay and dust above limit fail loads on arrival.
- Shell and deleterious material: crushed shell content in coastal sand sources is a real rejection cause in the Gulf.
- Moisture consistency: batching computers assume stable moisture; swinging moisture swings slump.
The configuration that holds spec
| Stage | Equipment | What it controls |
|---|---|---|
| Scrubbing | Spiral or log washer for clay-bound feed | Breaks clay coatings off grains |
| Classification | Hydrocyclone classifier | Cuts the 75 μm fraction to target |
| Dewatering | Dewatering screen | Stable 10–14% moisture for batching consistency |
| Recovery | Fines recovery on overflow | Puts saleable fines back into the envelope, not the pond |
Gradation is a blending problem
Most plants holding tight envelopes run two streams — a coarser washed sand and recovered fines — and blend at the stockpile. This is where the recovery unit earns its keep twice: once in yield, once in gradation control. We configure the cyclone cut point to your target curve, using your feed sample.
UAE project notes
- Ready-mix acceptance testing is daily; budget for a sieve shaker and train your operator to run gradation checks before the customer does.
- Jebel Ali receives the machinery; plant sites across the emirates are a straightforward haul.
- Water recycling is expected by Dubai and Abu Dhabi municipalities — see our Oman water-circuit notes for the closed-circuit design.

Sourced and inspected in Gongyi
- Sourced in Gongyi. Machines are built at qualified Gongyi-area plants we select and coordinate in Gongyi, Henan — with clear specs and transparent pricing.
- Test-run before shipment. Every line is trial-run or inspected at the plant before dispatch; you receive video evidence with the inspection report.
- Spare parts from stock. Wear parts and standard components ship with the machine, with manufacturer stock behind every order.
- 12-month warranty. Core machinery is covered for 12 months, backed by ongoing technical support coordinated by our team.
