SAND COOLER

Various types of coolers like water-spray type, fluidised bed type, vertical counter blow type are available.

1. Water-spray type:

• Fastest cooling method available.
• Ideal in case, where additional moisture is desirable.
• No need for any additional airflow.

2. Fluidised bed type:

• Ideal for fine grain and powder material for cooling.
• Cool air covers most of the grain surface for rapid cooling.
• Available for No-Bake and Lost Foam Process.
• Fluidization is done with a controlled amount of airflow help to remove dust and fines from the sand.
• Provision of a temperature sensing system for output sand.

3. Vertical counter blow type:

• • Gives counterflow to the vertically falling sand (or any grainy material).
  • Consumes less power and airflow compared to Fluidised bed type sand cooler.
  • Ideal for good availability of height.
