The High Energy Ball Mill Emax and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only minor warming effects. These ball mills are also suitable for mechano chemistry.

Mill liners fill a basic role: to protect your mills from the intense wear and tear that comes from grinding down hard, raw materials. But even if they all do the same job, not all mill liners are created equal. From the abrasion resistance of rubber to the impact resistance of steel, different material parts offer different advantages. FL supplies the full range of mill liners …

However, in this post, our focus is on wet grinding alone, which is usually performed at low speeds. Ball mills are used in pyrotechnics, except in the manufacture of flash powder because of its sensitivity to impact. Ball mills of high quality can grind materials to as small as 5 nanometers, but they are quite expensive.
