Rotor and Beater Mills are ideal for pre-crushing and fine comminution of soft to medium-hard, brittle, fibrous and temperature-sensitive materials in analytic laboratories or industry. The sample is comminuted at high speed by impact and shearing forces. The final fineness of the samples depends on the selected sieve insert.
To avoid undesired abrasion, the Variable Speed Rotor Mills can be equipped with rotors made of stainless steel, pure titanium, hardmetal tungsten carbide or zirconium oxide. The Cross Beater Mill is available with a grinding insert either made of cast iron or stainless steel, which is harder.
