Extending the life of your Mills and Grinders

Mills and grinders might sound like tools that peaked in laboratory uptake years ago, but scientists keep finding new uses for them. “There are lots of new applications for mills and grinders,” says Brian Vargo, product manager at Retsch, which operates its headquarters in Haan, Germany. “For one thing, folks are trying to do advanced materials research, like nanotechnology.”

In general, says Refika Bilgic, managing director at IKA Works in Wilmington, North Carolina, “Mills are commonly used in sample preparation for quality control—for example, tablets, seeds, waste samples, bio-fuels, foods, etc.” Those examples alone cover a wide range of applications for mills and grinders, but even more exist.

Getting finely ground materials also matters in areas that might not be expected, even by many scientists. For instance, Scott L. Anderson, distinguished professor of physical and analytical chemistry at the University of Utah, uses ball mills to make additives for rocket fuel. In some cases, Anderson takes micron-size boron, which can be purchased commercially, and grinds it to particles that are 50- 100 nanometers across. Then he coats the particles with an organic layer. “That prevents the metal from oxidizing prematurely and makes the metal particles readily dispersible in the fuel,” Anderson says. “The smaller particles heat up and burn faster, which is important for things like maneuvering thrusters that need pretty fast combustion rates.”

 Mills and Grinders - Questions from the Vault

We have so many questions filling our forums that sometimes questions can be missed and go without answers. Can you help us provide answers for these users with unanswered questions?

WAB Willy A. Bachofen DYNO®-MILL ML (Sterilization)
We are planning a small batch of nanocrystals for reserch, for a stability trial.  For this we need a sterile area.  How can we sterilize the Dyno Mill? Respond to this member.

Problems with grinding of ceramic slurries
Grinding a highly concentrated cermic slurry results in problems (sticking on walls of cup, heating during process) after processing in Retsch Planetary Ball Mill PM 100. How can this problem be avoided? In manuals, it is written that maximum feed grain size, for example, goes up to 1mm. Does it affect badly on grain size about 300 nm?  Share your knowledge and experience.

SPEX SamplePrep 6970 Freezer/Mill® condensation collection system
Is there any type of water collection system that the 6970 can be placed on top of, to collect the condensation the machine produces, that also utilizes a method of anti-vibration so not to disrupt the use of balances? Help this member.
