Patent ID: 7789596

Claim:
A system for forming an air suspension flow of insulation particles suitable for use in a process for forming an insulation product, comprising: a blowing machine for forming and blowing an insulation particle/air suspension through at least one outlet; at least one hose having an inner diameter in the range of about 2 inches to about 6 inches, for transporting the air suspension of insulation particles; a nozzle attached to an outlet end of the at least one hose and one or more spray nozzles for spraying a liquid binder onto the insulation particles, and a centrifugal booster fan in communication with the blowing machine, wherein the centrifugal booster fan is located downstream from the blowing machine, but upstream of the nozzle and the one or more spray nozzles and is connected to receive the air suspension flow of insulation particles into the input of the centrifugal fan to increase the velocity of the air suspension flow of insulation particles downstream of the booster fan, compared with the velocity of the air suspension flow of insulation particles received by the centrifugal booster fan and to increase the velocity of the air suspension flow of insulation particles through the nozzle to reduce the rebound of insulation particles and to produce a more consistent blown-in insulation product having improved properties, the centrifugal booster fan having an outlet that communicates downstream with the nozzle.
