Ball Mills

We are the largest supplier of small capacity
Ball Mills in the United States.

Basic Information & Operation:
Ball Mills are a very efficient tool for grinding many materials into a fine powder.
To use the Mill, the material to be ground is loaded into the Neoprene barrel which contains grinding media. As the barrel rotates, the material is caught between the individual pieces of grinding media which mix and crush the product into a very fine powder over a period of several hours. Quite simply, the longer the Ball Mill is run, the finer powder will be. Ultimate particle size depends entirely on how hard the material you're grinding is, and how long the Ball Mill is run.
Our Ball Mills have been used by tens of thousands of customers for grinding glass, creating custom varnishes, making ceramic glaze, powdering various chemicals, and making Black Powder.
All Ball Mills operate only on U.S. standard 115 volts, 60 Hz.
Every Ball Mill is 100% tested, and run continuously for 24 hours before shipping.
They are designed to operate continuously without failure.

Helpful Ball Mill Hints:

Media Choice: The best overall choice for grinding media is Chrome Steel. Due to its fairly high mass and hardness, it grinds chemicals & powders quickly and efficiently with minimal contamination. If you are milling Black Powder or Rocket Propellant, then Lead is the only media you can use as it is completely non-sparking. Lead is an extremely high mass grinding media but is fairly soft, which causes some contamination to the material being milled. In pyrotechnic materials this is not a concern and using either steel or ceramic media when milling Black Powder type materials can cause an explosion.
If you plan on grinding very hard materials (such as Glass particles) it is recommended that you use Chrome Steel media as it is both hard and heavy. When grinding Glass and similar hard substances, your starting material should be about as coarse as ordinary sand. The Ball Mill with then reduce it to a fine powder. Due to its small barrel diameter and lower impact energy, 3 pound mills are generally not suitable for grinding Glass or similar hard materials.
Ceramic media is a good choice when you must keep your media contamination to an absolute minimum and is ideal for milling individual chemicals. However, because of its light weight, ceramic media can take considerably longer to produce desired results.
Milling Time: The longer a ball mill operates, the smaller the particles will become. They will even reach the sub-micron level if the mill is allowed to run long enough. Always use as little material in the barrel as possible for maximum grinding efficiency. The more of your material you place in the barrel, the more it will cushion the impact of the media, reducing the grinding action. Several small capacity runs are much better than one long run with your barrel packed to capacity with the material you want to powder.
The more media you use, the faster the material will be powdered. However, using more media will reduce the capacity of your mill.
In the large 15 pound mill, you should ideally use a mixture of two different sizes of steel media (1/2" and 3/4" Chrome Steel or Ceramic Balls) will produce much faster results than compared to milling with either size media alone.
