What are the heat source options for sand dryers?

The production capacity of a sand dryer is usually measured by the amount of raw materials processed per hour, which can range from tens of kilograms to several tons. For example, a small laboratory dryer may process tens of kilograms of sand per hour, while a large industrial dryer can reach the capacity of processing tens or even hundreds of tons per hour. What are the heat source options for a sand dryer?

1. Gas: Use natural gas or liquefied petroleum gas and other fuel gases as the heat source, and burn them to generate high-temperature hot air for drying.

2. Biomass pellets: Use the heat energy generated by the combustion of biomass pellets for drying, such as wood chip pellets, straw pellets, etc.

3. Electricity: Use electricity for heating, and use electric heaters or electric hot air blowers to generate hot air for drying.

4. Firewood: The traditional firewood barbecue method is suitable for some areas without stable power supply and gas supply conditions.
