AP-42, CH 11.30: Perlite Processing

2015-9-10  At the expansion plants, the processed ore is either preheated or fed directly to the furnace. Preheating the material to approximately 430E C (800E F) reduces the amount of fines produced inthe expansion process, which increases usable output and controls the uniformity of productdensity. In the furnace, the perlite ore reaches a temperature of 760E Cto (14980 0 to 1800E F), atwhich point it begins to soften to a plastic state where the entrapped combined water is released assteam. This causes the hot perlite particles to expand 4 to 20 times their original size. A suctionfan draws the expanded particles out of the furnace and transports them pneumatically to a cycloneclassifier system to be collected. The air-suspended perlite particles are also cooled as they aretransported to the collection equipment. The cyclone classifier system collects the expanded perlite,removes

Expanded Perlite - Bergama Perlite

Expanded Perlite. Perlite is a generic term for naturally occurring siliceous rock. It is distinguished from other volcanic Limestonees, when heated to a suitable point in its softening range, it expands from four to twenty times its original volume. This expansion is due to the presence of two to six percent combined water in the crude perlite rock.
