Drum Washer to Clean Brass Shell Casings – Case Study 21132

Background:

This key corporation in the defense, aerospace, security and outdoor sport industries needed to clean 7.62mm brass shell casings in the manufacturing process.

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.

The System/Solution:

A 3-stage D-24 Drum Washer with a 24-inch diameter drum that cleans the brass shell casings after the final press… The system outputs 26,000 shells per hour, sending them to final machining. The stages are alkaline wash to remove the stamping fluids followed by rinse and dry. All wetted parts of the system are stainless steel. The drum has “scoops” to bring the fluids into the drum (there are no pumps). In the wet stages, the shells are fully immersed.
