Three-Pass Rotary Sand Dryer for Mortar Sand Preparation
Three-pass rotary sand dryer for dry mortar plants that need lower sand moisture before screening, storage and weighing. This design suits projects that want a compact drying section before the mixer and need more stable sand condition for tile adhesive, plastering mortar and other specialty mortar products.

Why This Dryer Fits Mortar Projects
For dry mix mortar production, sand moisture directly affects weighing accuracy, storage condition and final product stability. A practical dryer is not only about evaporation capacity. It also has to match your fuel condition, target tonnage and the rest of the aggregate handling line.
Lower Heat Loss
The three-pass structure keeps the drum path more compact and helps reduce heat loss compared with simpler drying routes.
Stable Sand Before Batching
Dryer sizing should match the moisture of the incoming sand so the downstream screen, silo and weighing section can work more consistently.
Easier Line Integration
The dryer can be matched with hot air furnace, conveyors, dust collection and vibrating screen as one aggregate preparation section before the mortar plant.
Typical Use and Matching Scope
NEO usually recommends the dryer as part of a practical process route instead of supplying the drum alone.
Best For
- New mortar plants using damp river sand or manufactured sand.
- Projects that need lower moisture before storing sand in finished bins.
- Customers who want to add screening and grading after drying.
- Factories that need a compact dryer before a specialty mortar line.
Typical Support Modules
- Hot air furnace selected by fuel type and local condition.
- Belt conveyor or bucket elevator before and after drying.
- Vibrating screen for final sand grading.
- Cyclone and pulse dust collector around transfer points.
- Storage hopper or finished sand silo before mortar batching.

Reference data only. Final recommendation should still be checked according to your raw sand moisture, target final moisture, fuel type and installation layout.
What We Need Before Recommending a Model
A dryer should be selected by your raw material condition first, not only by target capacity.
- Raw sand moisture range and the target moisture after drying.
- Target output per hour for the mortar line.
- Whether the dried sand will go to screening, storage silo or directly to batching.
- Available fuel condition such as gas, coal, diesel or biomass.
- Site layout, environmental requirement and dust collection expectation.
Product Photos & Selection Details
Sand dryer selection depends on initial moisture, final moisture target, fuel condition, dust collection and downstream storage.

| Selection Item | What to Confirm | Why It Matters |
|---|---|---|
| Raw material condition | Stone or sand type, feed size, moisture and hardness. | Raw material decides dryer, crusher and wear-part configuration. |
| Final sand target | Moisture, particle size, grading and shape requirement for mortar use. | Mortar-grade sand needs stable moisture and suitable grading. |
| Capacity target | Tons per hour, daily output and operating hours. | Capacity affects main machine model, burner, screen and conveyors. |
| System matching | Dust collector, screening, storage silo and link to mortar plant. | Aggregate treatment should connect smoothly with the mixing line. |

FAQ
Common questions before choosing a sand dryer for a mortar project.
Is this dryer only for yellow sand?
No. The parameter sheet also includes slag, fly ash and clay directions. For mortar projects, the most common discussion is dried sand before screening and mixing.
Do I need screening after drying?
Usually yes. Many dry mortar projects still need vibrating screening after drying so the final sand grading matches the target formula better.
Can NEO match the dryer with the full aggregate section?
Yes. NEO can combine the dryer with furnace, conveyors, screen, dust collector and storage arrangement before the mortar batching system.
Can NEO match this machine with my mortar sand requirement?
Yes. Please provide raw material, feed size, moisture, target grading and output. NEO can suggest a dryer, crusher, screen and storage combination for mortar-grade sand.
Need a dryer before your mortar mixer?
Send raw sand moisture, target output and fuel condition. NEO will suggest a practical dryer size and support module direction.
