process for manufacturing expanded perlite

AP-42, CH 11.30: Perlite Processing

Crude perlite expanded for use as a concrete aggregate ranges from 1 mm (plus 16 mesh) to 0.2 mm (plus 100 mesh). Ninety percent of the crude perlite ore expanded for horticultural uses is greater than 841 µm (20 mesh). Crude perlite is mined using open-pit methods and then is moved to the plant site where it is stockpiled.

The Egyptian Co. For Manufacturing Perlite E.C.P

Perlite is not a trade name but a generic term for naturally occurring siliceous rock. The distinguishing feature which sets perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, it expands from (4 : 20) times its original volume. This expansion is due to the presence of (2 6 )% combined water in the crude perlite rock.
