For extremely fast comminution (speed: up to 1500 rpm) of hard, medium-hard, brittle laboratory samples dry or in suspension to analytical fineness. Max. Feed size: (depending on material) 12 mm Max. Throughput per batch: 250 ml Final fineness: 10 - 20 µm Rotor speed: up to 1500 rpm Application field Mining, metallurgical, ceramics, agriculture and environment, infrared and X-ray fluorescence analysis Method of operation In the disc vibratory mill, grinding is carried out by horizontal oscillations of the grinding set on a vibrating plate. The grinding set consisting of ring and core crushes the regrind by extremely high pressure, impact and friction effects. In this form of grinding, the transfer of forces to the regrind is even more important than the pure engine power. A special motor equipped with a particularly interference-free, torque-optimized frequency inverter meets all relevant safety standards worldwide. It ensures that the performance of the engine is adapted exactly to the respective regrind and the grinding set - thus optimizing energy consumption. The features at a glance more power with a new drive concept extra fast grinding with up to 1500 rpm setting of speed, grinding time and pause times per second accurate programming and storage of grinding cycles self-explanatory multilingual menu guided ergonomic setting of the grinding set significantly lighter grinding sets with heat-insulated handles optimized clamping of the grinding set particularly secure hood lock with anti-twist protection complete sound insulation lining dry or wet grinding 2-year guarantee Equipment The disc vibratory mill PULVERISETTE 9 is supplied as standard with no grinding fittings. Grinding sets are available in 5 different materials and 3 different sizes from 50 ml to 250 ml capacity and can be ordered as accessories: Grinding set hardened steel for brittle, hard samples Grinding set chrome-free steel for brittle, hard samples Grinding set tungsten carbide Tungsten carbide for very hard, abrasive samples Agar grinder for soft to medium-hard, brittle, fibrous samples without metallic contamination Grinding zirconia medium-hard, brittle, fibrous samples and for iron-free grinding
