  • AP-42 CH 11.30 Perlite Processing

     · 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
