WHY RANGE MINER

WHY RANGE MINER

The Range Miner Difference

The initial goal was to make a tumbling machine for brass casings without the problematic noise. Mitigating the noisiness was achieved by suspending and isolating a cylinder within a cylinder, the theory being of like sound waves  when they bounce and meet cancel. In this application the theory proven. 

A drum large enough to satisfy a reasonable amount of brass / media also proved to be heavy and unwieldy.  
 So why not separate the outer drum into multiple cylinders? That way you can load different calibers, use different media or separate according to condition or grade of brass. By making them easy to remove ,  they would be easy to handle for filling and emptying and you would not have to remove the entire outer drum. Four 4" cylinders in a 12" drum worked perfectly.

Conventional wisdom dictates baffles, ridges or like obstructions to agitate the contents, right? The brass- media movement was re-evaluated and corrected by em-placing simultaneous lateral motion in conjunction with rotary motion. This way the brass is kept always in contact with the media , with no interference, a subtle modification, but producing highly effective results. 
All Aces.  
  
You can easily Load 250 Rem. 223 casings in one cylinder, 400  9 MM Luger in another cylinder, 150 308 Win. in another cylinder and 350 38 Special in the remaining cylinder. All with different media or any combination that suits you. 
All in the same roll.

HOW IT WORKS

Simple & Powerful

1 1

Drive train

Power is supplied by a 1/4 HP 120 volt commercial motor on an anti- vibration mount controlled by a timer switch. Pulleys driven by belt, transfer power to the drum rollers. 
2 2

Outer drum

This has 3 purposes; to house the inner drum carrier, sound mitigation and to provide a contact surface for drive rollers.

Cylinders 

Where the work happens. The four cylinders have a capacity of 150 cubic inches or approx. 2.5 liter of free space. Load wet or dry.
4 4

Carrier

This is located inside the outer drum used to position the cylinders. The 3 part framework provides equal clearance between the cylinders and the outer drum. They also provide the cant necessary to create constant lateral movement when in motion.         
5 5

Numbered cylinder locks

These hold the cylinders in place and prevent cylinder rotation in the carrier. Numbered identity is used to record the contents.
