Vibratory Micro Mill PULVERISETTE 0. FRITSCH, Germany

תיאור

Impact and Friction

The FRITSCH Vibratory Micro Mill PULVERISETTE 0 grinds your sample through impact and friction by which the mortar vibrates electromagnetically and the grinding material transfers the vibrations to the grinding ball. At the beginning of the grinding, the comminution of the coarse particles is achieved by the impact effect of the grinding ball. Next, the fine particles are comminuted through friction by the tumbling motion of the grinding ball as the vibrations subside. The impact energy of the grinding ball is freely adjustable thus, allowing it to be precisely adapted to the sample being ground.

• Adjustable oscillation amplitude for easy adaption of the vibration energy to the grinding sample
• Grinding bowl oscillations 3,000 – 3,600 oscillations/min at 1 – 3 mm amplitude
• Agglomeration phenomena avoided
• Ergonomically positioned membrane keyboard IP65, splash-proofed
• Window for observing the grinding progress
• Digital Timer
• Extensive accessories for simplifying your daily work

FRITSCH cryo-box

For fast embrittlement of soft, slightly oily, fatty or moist materials, for cryogenic grinding, we offer the FRITSCH cryo-box: Simply insert the filled grinding set into the cryo-box and fill it with liquid nitrogen, with this method even extremely difficult-to-grind samples can be ground down to analysis fineness. And the thick insulation ensures a particularly efficient use of coolant.

Comminution and sieving in one unit

For dry and wet sieving, the FRITSCH PULVERISETTE 0 can be converted into to a Vibratory Sieve Shaker for quantitative particle size analysis of solids (measuring range 32 μm – 63 μm) and suspensions (measuring range 20 μm – 10 mm) by simply inserting corresponding sieves.

Mortar and grinding balls

The Vibratory Micro Mill PULVERISETTE 0 operates with a mortar, which is equipped with a grinding ball. All FRITSCH mortars are rimmed, regardless of the material, in a robust shell of shock-resistant aluminium, which protects the actual mortar. To optimally adapt the grinding to any sample type, you can choose between 6 different materials, whereby mortars and grinding balls of the same material are generally used. For cryogenic grinding, use mortars and grinding balls made of steel or tungsten carbide.
