Planetary Mills and Ball Mills – Particle Size Reduction
Ball mills reduce the particle size of sample by using a combination of impact and friction energy. This energy, which is created by the moving grinding balls, breaks down the sample to achieve the final fineness. FRITSCH offers a number of different ball mills, depending upon the application under consideration.
Fundamental to all ball milling is the selection of material of construction for the grinding set; the grinding material must be harder than the sample being prepared. Depending upon the instrument, there may be up to seven different materials of construction available for the grinding set. These materials of construction include: agate, sintered corundum, silicon nitride, zirconium oxide, stainless steel, tempered steel and tungsten carbide.
Not only do considerations need to be given to the hardness of the grinding set, but also to the fact that some abrasion of the grinding set will take place contaminating the sample.
For very fine ball milling to a final fineness of <20μm, wet milling has to be used; all Fritsch ball mills are suitable for this type of application.
As well as particle size reduction ball mills may be used for the homogenisation of pastes and emulsions.
Through the continuous measurement of gas pressure and temperature, it is even possible to investigate mechanical alloying and the production of new materials
For advice on the most suitable laboratory sample preparation technique for your material, please enter the details of your material; indicating the amount of sample, the starting size and the final fineness required on our contact information sheet. We will then be able to advise on which Fritsch laboratory sample preparation instrumentation will fulfil your requirements.
