For fine comminution of dry laboratory samples or solids in suspension. For homogenisation of emulsions or pastes.
The Vibratory Micro Mill PULVERISETTE 0 is recommended for sample preparation of RoHS tests (Restriction of Hazardous Substances).
Method of operation
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.
Features overview
Selective comminution. At the start of the grinding, comminution of the coarse particles by impact. As a consequence of the whirling movement of the grinding balls, comminution of the fine portion through friction
Configurable oscillation amplitude, allowing the oscillation energy to be adapted to the grinding sample
Comminution in a narrow, homogeneous grain size range
Modular system, easy conversion to dry or wet sieving
Certified safety (CE mark)
Lossless grinding in enclosed vessel, also possible in suspensionEquipment
The grinding lid is included in the standard equipment delivered with the Vibratory Micro Mill (included in the price of the instrument). Mortars and grinding balls are offered in 6 different materials and must be ordered as accessories. The PULVERISETTE 0 can also be converted to a Vibratory Sieve Shaker ANALYSETTE 3 SPARTAN for dry and wet sieving.

Accessories
Please note: For this FRITSCH mill, you require a mortar and one grinding ball. The mortar material must also be harder than the material to be ground. In normal cases, a mortar and ball of the same material are used. For cryogenic grinding, please use mortars and grinding balls of steel or tungsten carbide.
The PULVERISETTE 0 can also be converted to a Vibratory Sieve Shaker ANALYSETTE 3 SPARTAN for dry and wet sieving.

Material data for mortars/grinding balls
| Material | Main component of the material | Density g/cm³ | Abrasion resistance | Used for grinding material |
| Agate | SiO2 | 2.65 | Good | Soft to medium-hard samples |
| Sintered corundum | Al2O3(99.7 %) | 3.8 | Moderately good | Medium-hard, fibrous samples |
| Zirconium oxide | ZrO2 | 5.9 | Very good | fibrous, abrasive samples |
| Stainless steel | Fe - Cr - Ni | 7.8 | Moderately good | Medium-hard, brittle samples |
| Tempered steel | Fe - Cr | 7.9 | Good | Hard, brittle samples |
| Hardmetal tungsten carbide | WC | 14.95 | Very good | Hard, abrasive samples |
In normal cases, mortars and grinding balls of the same material are used.
For cryogenic grinding, use mortars and grinding balls made of steel or tungsten carbide. Grinding sets made of agate and sintered corundum are not suitable for cryogenic grinding.
