Automotive - Finishing Sand Blow-off

Application:

Assist with the removal of the bulk/ majority of the casting sand off of molded flanges of utility cargo boxes traveling at 20fpm, prior to final assembly

Background:

Customer produces utility tractors which are fitted with various unloaders/cargo boxes. They attempted the same solution as many other manufacturer’s by using existing compressed air. They utilized

(4) 2” nozzles fed from a 4” compressed air header at 85psig. This required 86hp per nozzle, not to mention the elevated noise levels estimated at 108+ dbA.

Problem:

The problem was not the performance of the blow-off, but more an issue of reducing the noise level, as well as the associated cost of compressed air usage for operating (4) 2” nozzles, estimated at requiring 64kW/Hr to operate each nozzle

“Engineered” Solution:

Sonic 300 50hp Dual Blower system

•: (6) 1” nozzles

Producing 1,125cfm @ 3 psi with an exit nozzle velocity of 33,000 fpm @ 93dbA

Special Points of Interest:

Reduced compressed air usage by 86kW/hr or 73% per hour
Freed up plant air for other operations
Provided a quieter work envirnoment
