  • About PerllteWhat is Perlite? Hess Perlite

    The global perlite industry actively mines a total of less than 8 square km (3 sq miles)—about 1% of the total perlite deposits available worldwide. Perlite mining has limited environmental impact. There is little overburden to manage, minimal waste, and no chemicals are needed to process the ore. Once mined, perlite does

    Crude perlite ore is mined, crushed, dried in a rotary dryer, ground, screened, and shipped to expansion plants. Horizontal rotary or vertical stationary expansion furnaces are used to expand the processed perlite ore. The normal size of crude perlite expanded for use in plaster aggregates ranges from plus. 250 micrometers
