The equipment used to expand vermiculite in industry is called Vermiculite Expansion Furnace. According to the different fuels used, vermiculite expansion furnaces can be divided into natural gas vermiculite expansion furnaces and gas vermiculite expansion furnaces. Before the raw vermiculite expands into the Vermiculite Plant, it needs to be preheated and dried the water percent below 5% . Our company's Vermiculite Expansion Equipment can expand raw vermiculite to tens of times the original volume. Expanded Vermiculite can be mixed into compound fertilizer to increase crop yield, and can also be used as thermal insulation material.
