A Comprehensive Guide to Process and Equipment for Sand Drying

High-quality sand used in construction or other industries is usually sourced from rivers, lakes, and seas, and will often contain high moisture content. Normally, it would be unsuitable for immediate use. To make sure the quality and stability of sand for industrial applications will work for your project, it has to go through a drying process using specialized sand drying equipment. Here’s a look at that process and how to find kiln support roller help.

What is Sand Drying?

Sand drying is the process of removing moisture from wet sand or sandy materials to achieve a desired level of dryness. This process is typically carried out using sand drying equipment, which employs hot air or other heat sources to evaporate or vaporize the moisture in the sand.

Why Sand Drying is Important

  • Quality improvement: Removing moisture from sand enhances its quality and stability, reducing the risk of decay and mold growth.
  • Extended shelf life: Lowering the moisture content of sand extends its shelf life, improving its utilization rate and market competitiveness.
  • Reduced transportation costs: Dried sand is lighter, which reduces weight and costs during transportation.

Process for Sand Drying

Belt Conveyor

Wet sand is transported to the sand drying production line via a belt conveyor, which ensures even distribution of the material.


The mixer breaks up large clumps of wet sand, preventing them from sticking together and facilitating the drying process.

Wet Sand Storage Bin

The wet sand is temporarily stored in a storage bin for controlled feeding into the vibratory feeder.

Vibratory Feeder

The vibratory feeder then disperses the sand particles, breaking them down into smaller clusters before scattering them onto the next belt conveyor.


A heating furnace provides the heat source for the dryer, generating high-temperature heat through fuel combustion.


The fan facilitates heat transfer from the furnace into the dryer, enabling moisture evaporation, adjusting airflow, transporting drying materials, and exhausting waste gasses.

Temperature Control System

This system monitors and regulates the temperature during the drying process for stability and safety.

Drive Unit

The drive unit powers the rotation of the dryer drum for uniform exposure of wet materials to the heat source.

Rotary Dryer

Inside the dryer, the wet sand comes into contact with hot air, accelerating heat and mass transfer and evaporating moisture.

Dust Collector

The dust collector removes dust and solid particles generated during the drying process, ensuring clean and dust-free discharged gas.

Vibratory Feeder

The vibratory feeder disperses and transports materials. By vibrating the sand, the feeder breaks it down into smaller particle clusters, dispersing larger sand chunks. This creates a more uniform and efficient drying process.

The Belt Conveyor

The belt conveyor connects various stages of the process and creates the continuous and stable transportation of sand by evenly distributing it on the conveyor surface, improving production efficiency and operational speed. The belt conveyor also saves labor resources and increases automation in production.
