Spherical obturator perlite is a low water absorption and high strength characteristics of the new insulation material. → ore processing by automatically feeding → preheating → automatic blanking →-heating → Products Cold and automatic transmission → product collection → → classification measurement products packaging → storage. The product expanded by the high-temperature furnace, the expansion of perlite particles found on the surface of micro-round and have a glass of consecutive frames, Pore closed for the hollow interior of the structure.

Main purposes : the product has high strength, low water absorption, easy dispersion notable feature can be used for increasing mobility, widely used outside wall insulation mortar, decorative plates, thermal insulation panels of light aggregate use, the same time instead of part Zeeospheres use. It can also serve as a building, metallurgy, industrial furnace (light firebrick aspects), and other industries use.
