ICMIEE-PI-140116 Development of new perlite/sodium ...

2017-1-5  Perlite is a glassy volcanic rock of rhyolitic composition, which can be processed into an expanded form for cellular structure formation [2,3]. The expansion takes place due to the presence of water in perlite when heated to about 649-816oC. The expanded perlite particles are light, environmentally friendly, and possess good acoustic and insulation properties. They have been used as additives or main components for composites, e.g. Portland cement/perlite composites for blocks [8-10], perlite/sodium silicate boards, roof insulation panels made of perlite/fibers/bituminous material, fibre reinforced perlite/cement composites, building boards made of fiber/asphalt coated perlite or urea–formaldehyde resin/mineral fibers/gypsum/glass fibers, fibre reinforced sodium silicate/perlite composite, moisture resistant gypsum boards

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
