Dear Ali,
I have been doing physical exploration for years, mainly through wet milling. I tried a vibrating mill and a stirred ball mill at the time. For me, wet grinding only led to a goal for optimal physical exploration. I checked the state of exposure by light microscopy, electron microscopy and X-ray diffraction. May I ask why you are looking for dry processes? Due to energy factors? Wet processes have several advantages. I have summarized the benefits of wet procedures that I have experienced for myself. I recommend reading this publication to you:

Dear Ali,
I invite you to read about our latest findings on application of electromagnetic mill in dry (and wet) ultra-fine milling e.g of copper ore. Comparison of dry and wet milling is described here:
Article Comparison of Wet and Dry Grinding in Electromagnetic Mill
Most of the other research results are gathered in this RG project:

Hi Ali, there are some dry comminution technologies at various stages of development. Key among them are VRM (vertical roller mill) - large-scale and a novel superfine crusher - laboratory-scale (I used this technology in my PhD). It is energy efficient with significantly higher reduction ratio than conventional crushers. I was able to crush selected high-silica magnetite ores from top size of 32mm to generate product with P80 of 1.43 mm and d50 of ~500 µm in a single-stage open circuit. I have published some papers on it that you can use as reference.
There is another new comminution technologies that is under development in Australia. Feel free to contact me to discuss further.
