CM500 Case / Media Separator
Why You Need a Case-Media Separator
By Duane Thomas
Once you’ve cleaned your brass, it’s sitting there inside the Dillon vibratory case cleaner, all nice and clean for loading, but still nestled in the case cleaning media. Obviously, removing cases by hand, and pouring media out of each and every one, would be entirely too time-consuming. Wouldn’t leave you with the cleanest hands in the world either. So, how to swiftly and efficiently separate the cases from the media, ideally while leaving you with clean hands? Good question! Dillon Precision answered that when they designed a device called the case-media separator.
The case-media separator comes in two pieces, (1) a plastic basket with multiple open slots all over it, (2) a largish tub with two metal brackets, one to each side, centered on the tub’s long axis. There’s a doglegged handle running through the basket, and its through-rod rests on the brackets. Coming out of one side of that rod is a prong that fits down into a hole in one of the brackets, to stabilize the basket, and prevent it from moving around. The basket is in two pieces, hinged on one side.
Open up the basket and pour the contents of the vibratory case cleaner, all the cases and media, too, into the part of the basket that’s over the middle of the tub. Most of the media, its individual granules being smaller than the slots in the basket, will run through it and be caught in the tub – but not all of it. Close up the basket, there are two clamps to hold it shut, lift up on one side of the basket and move it slightly to the side, so the stabilizing prong is no longer in the corresponding hole in the bracket. Now the basket can move freely. Begin cranking the handle, the basket will spin, cases will bounce around, dislodging any media, and centrifugal force will cause it to be flung out of the basket, through the slots.
We knew from the beginning that the simplest method of separating would be a rotating cage, but we had to find a design we could manufacture economically. The solution was an injection molded reversible part. It's simple, and it works great. The CM-500 Case/Media Separator is designed to handle the load of a CV-750 Case Cleaner which is about 500 pieces of 45ACP or 38/357, or about 200 pieces of 30-06 brass. The tub measures 13.5" x 19.5"
