This key corporation in the defense, aerospace, security and outdoor sport industries needed to clean 7.62mm brass shell casings in the manufacturing process.
Parts Cleaning Problem:
They were using 70 year old parts washers that no longer cleaned their parts efficiently or effectively. They needed new washers to clean the shell casings after heat treatment.
A 5-stage D-24 Drum Washer with a 24-inch diameter drum that cleans shell casings after heat treatment…
The system outputs 40,000 shells per hour. Shells are put through the following 5 stages: acid pickling to remove the heat treatment scale, rinse, rinse, lube, and dry. All wetted parts of the system are stainless steel. The drum has “scoops” to bring the fluid into the drum (there are no pumps). In the wet stages, the shells are fully immersed.
