Silica Sand Dryer
Industrial Rotary Drying System for Silica Sand, Quartz Sand, Frac Sand and Other Industrial Sands Tongding silica sand dryers are designed for continuous drying of silica sand, quartz sand, frac sand, glass sand, foundry sand and other granular mineral materials.
Features:
- Heat Source: Coal / Gas / Biomass
- Capacity: 3–120 TPH | Customizable Drying System
- For typical silica sand applications, the system can be designed to reduce moisture from around 6% to below 0.5% under suitable operating conditions.
- The drying system can be configured according to the actual material characteristics, including feed moisture, target final moisture, particle size, bulk density, required capacity and heat source.

Silica Sand Drying from Around 6% to Below 0.5% Moisture
For dry-mix mortar, glass sand, foundry sand and other industrial applications, moisture control directly affects downstream processing.
Tongding drying systems can be configured for silica sand with typical feed moisture around 6% and a target final moisture below 0.5%, when the material and operating conditions are suitable.
The dryer is sized according to the actual production requirement rather than capacity alone.
Key factors include:
- Feed moisture
- Target final moisture
- Required capacity
- Particle size distribution
- Bulk density
- Material characteristics
- Heat source
- Downstream screening and storage requirements
Applications
Working Principle
Wet silica sand is fed into the rotary dryer through the feeding system.
Inside the rotating drum, the material is continuously lifted and dispersed by the internal flights. Hot air passes through the material, transferring heat and evaporating moisture.
The dried material moves toward the discharge end and is then conveyed to screening or storage.
Dust-laden exhaust gas passes through the dust collection system before discharge.
The complete system can be configured according to the required capacity, material characteristics and downstream process.
Complete Silica Sand Drying System
For projects requiring more than a standalone dryer, Tongding can integrate the main equipment into a complete drying system.
Typical Equipment:
This configuration can be expanded or modified according to the customer's production process.
Heat Source Options
Different projects have different fuel availability and operating costs. Tongding drying systems can be configured with different heat sources according to local conditions.
Typical options include:
- Natural Gas
- Diesel
- Biomass
- Coal
The appropriate heat source depends on local fuel availability, required drying capacity, material moisture and operating requirements.
Technical Specifications
| Model | Motor Power | Capacity | Drum Speed |
|---|---|---|---|
| HG1625 | 4 kW | 3–8 TPH | 9 rpm |
| HG2240 | 7.5 kW | 10–15 TPH | 9 rpm |
| HG2250 | 7.5 kW | 20 TPH | 9 rpm |
| HG2958 | 5.5 kW × 4 | 30 TPH | 7 rpm |
| HG3270 | 11 kW × 4 | 60 TPH | 7 rpm |
| HG3890 | 15 kW × 4 | 100 TPH | 7 rpm |
Customized configurations up to 120 TPH can be considered according to project requirements.
For final equipment selection, capacity should be evaluated together with feed moisture, final moisture, material properties and heat source.
What Information Do We Need for Dryer Selection?
A silica sand dryer should not be selected by capacity alone.
For a technical proposal, please provide the following information:
| Required Information | Example |
|---|---|
| Material | Silica Sand / Quartz Sand / Frac Sand |
| Required Capacity | 20 TPH |
| Feed Moisture | 6% |
| Target Final Moisture | <0.5% |
| Particle Size | Mesh / mm |
| D50 | If available |
| Bulk Density | If available |
| Heat Source | Gas / Diesel / Biomass / Coal |
| Application | Dry Mortar / Glass / Foundry / Frac Sand |
| Destination | Country / Port |
If some laboratory data are not available, send the information you already have. Our engineers can determine which additional parameters are required for equipment selection.
