Vermiculite Expansion Furnace

What is vermiculite ore ?

Vermiculite is a natural, inorganic, non-toxic mineral that will expand under the action of high temperature. After high-temperature roasting, the volume of vermiculite can rapidly expand several times to dozens of times. The expanded vermiculite is called expanded vermiculite. The high-quality expanded vermiculite can reach a maximum temperature of 1100°C.

Expanded vermiculite has good electrical insulation, widely used in thermal insulation materials, fireproof materials, seedlings, flowers, trees, friction materials, sealing materials, electrical insulation materials, refractory materials, smelting, construction and other fields.

vermiculite application areas

• (1) Architecture: insulation and heat insulation of building roofs and walls; lightweight aggregates of building materials.
• (2) Industrial: Dip-pressed hydrophobic perlite insulation board, sound absorbing panel, partition wall panel, fireproof panel, etc.
• (3) Deep cold, low temperature engineering insulation, industrial equipment, pipeline insulation, etc.
• (4) Agriculture and horticulture: soil improver, soilless culture substrate, pesticide retardation agent.
• (5) Others: filter aids, fillers, abrasive materials, slag materials for steel making processes, etc.

Overview of Vermiculite Expansion Furnace

Vermiculite Expansion Furnace is different with perlite expansion furnace, the whole system not have preheating furnace and the furnace’s inner structure is equipped with baffle plate to increase the residence time of the vermiculite in the furnace body, uniform distribution and better puffing.
