Rotary Drum Washer for Small Ammunition Cleaning

In this drum washer, 7.62mm shell casings 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. The system outputs 40,000 shell casings per hour.
