OPTIMAL SAMPLE PREPARATION for first-rate analysis The quality of every product or material analysis depends on the quality of the sample preparation. It is therefore extremely important to consider all the individual milling parameters in order to make an informed choice: material properties of the sample such as density, degree of hardness, feed size, sample quantity, grinding time and desired final fineness, any abrasion of the grinding parts, temperature sensitivity or residual moisture – all these factors are significant. And of course the costs. For this reason, FRITSCH offers a wide selection...

Choosing the right type of comminution Each material has specific breaking characteristics. The wide range of FRITSCH laboratory mills always offers the perfect solution for this purpose. Hard and brittle materials, for example, require pressure, impact or friction for efficient comminution, in this case Planetary Mills, Vibratory Mills, Disk Mills, Mortar Grinders or Jaw Crushers are the right choice. In contrast, soft and fibrous materials can be ideally ground with shearing and cutting action, as provided by Cutting Mills, Knife Mills, Variable Speed Rotor Mills and Cross Beater Mills. Comminution...
