ABSTRACT:
Expanded perlite is produced while simultaneously or substantially simultaneously coating the expanded perlite with an hydrophobic coating material by passing the expanded perlite and heated expander exhaust gases from the expansion chamber through a cooling and coating chamber provided with spray nozzles to provide a stream of atomized coating material onto the expanded perlite, while upstream thereof an air intake and temperature sensor are situated to control the air flow and temperature in the cooling and coating chamber so as to provide proper curing temperatures for the coating material upon the expanded perlite before it is separated from the exhaust gases.
