Fritsch® PULVERISETTE 14 classic line Variable Speed Rotor Mill 100-120V 50-60Hz 1~

For fast, effective comminution of soft to medium-hard, brittle as well as fibrous materials and temperature-sensitive samples. Max. Feed size: (depending on material) 10 mm Max. Throughput: (depending on material and sieve size) 5 l/h Final fineness: (depending on sieve insert) 0.08 - 6 mm Rotor speed: 6,000 - 20,000 rpm Range of application Soft materials such as plants, wood, roots, leaves, needles, spices, textiles, leather, chemicals, foodstuffs, grain, cellulose, fillers, chalk, kaolin, coal, soil (without stones). Medium-hard materials such as pharmaceuticals, coated tablets, tablets, fertilizers, pellets, animal feed Temperature-sensitive samples can be comminuted because the fast, effective grinding reduces the thermal load on the material to be ground. Samples that are difficult to grind, such as styrenes, polyesters, synthetic resins, films, PVC, PP and PE, can be embrittled, for example, by adding liquid nitrogen and then ground to analytical fineness. Furthermore, the Variable Speed Rotor Mill PULVERISETTE 14 is also used for sample preparation according to RoHS. Method of operation A very fast running rotor with integrally formed ribs comminutes the sample by impact action. In addition, the sharp-edged teeth together with the inserted sieve cut the sample by shearing. In the final comminution stage, the sample is stressed by friction between the rotor and sieve. The performance features at a glance Exchange system consisting of rotor, collecting vessel, sieve and labyrinth seal, completely removable and reinsertable without tools Regulated rotor speed (6,000-20.000 rpm) Optimum grinding chamber forced cooling with extremely high air throughput Heavy-duty, wear-free rotor made of stainless steel, hardened Wear-free labyrinth seal between grinding chamber and drive motor High speed stability even under full load Conversion kit for iron-free grinding Equipment As standard, you will receive the Variable Speed Rotor Mill PULVERISETTE 14 with collecting vessel and lid. Beater rotors and sieve rings are offered in various designs and materials and can be ordered as accessories. A sieve ring WC-coated with 0.25mm trapezoidal hole is also offered.
