The product is made by the small selected particle ore, after heating& selective expansion in a vertical shaft kiln, and expansion perlite again by grinding to be certain particle powder products. Main features White, odourless, non-toxic.According to bulk density, grain size match, the expansion of formation of pore diameters and other differences , the product can be divided into fast, medium-speed, slow three varieties.
