OVERVIEW FRITSCH Planetary Ball Mills – high-performance all-rounder in routine laboratory work The Planetary Micro Mill PULVERISETTE 7 premium line with 2 grinding stations is designed for a broad range of applications and ideally suited for loss-free grinding down to a final fineness of 50 nm of hard, medium-hard and brittle materials. Depending on the desired final fineness, the grinding can be performed dry, in suspension or in inert gas. In addition to comminution, you can also use Planetary Mills for mixing and homogenising emulsions and pastes or for mechanical activation and alloying in materials research.

FRITSCH Planetary Ball Mills – high-performance all-rounder in routine laboratory work

The Planetary Micro Mill PULVERISETTE 7 premium line with 2 grinding stations is designed for a broad range of applications and ideally suited for loss-free grinding down to a final fineness of 50 nm of hard, medium-hard and brittle materials. Depending on the desired final fineness, the grinding can be performed dry, in suspension or in inert gas. In addition to comminution, you can also use Planetary Mills for mixing and homogenising emulsions and pastes or for mechanical activation and alloying in materials research.

Comminution according to the Planetary-Principle

The comminution takes place primarily through the high-energy impact of grinding balls and partially through friction between grinding balls and the grinding bowl wall. To achieve this, the grinding bowl, containing the material to be ground and grinding balls, rotates around its own axis on a main disk rotating in the opposite direction. At a certain speed, the centrifugal force causes the ground sample material and grinding balls to bounce off the inner wall of the grinding bowl, cross the bowl diagonally at an extremely high speed and impact the material to be ground on the opposite wall of the bowl. Due to sunken grinding bowls, the high-performance Planetary Micro Mill PULVERISETTE 7 premium line reaches unprecedented relative rotational speeds of the grinding of up to 2,200 rpm and centrifugal accelerations of 95 times the force of gravity. Thereby is the application of energy approximately 150 % above that of conventional Planetary Mills. For ultra-fine grinding results down into the nano range in shorter times. Your advantage: the shortest grinding times down to any desired fineness, even into the nano range.

Rotational speed of main disk 150 – 1100 rpm, relative rotational speed of grinding bowls up to 2200 rpm

Absolutely safe operation – due to the revolutionary SelfLOCK, grinding bowls snap into place in the machine – without any additional clamping

Blocking of the mill in the event of impermissible operating states

Automatic shutoff function if an imbalance occurs

Prevention of impermissible grinding settings due to automatic detection of inserted grinding bowls and optimisation of rotation speed via RFID-Chip

Automatic parameter check before each grinding guarantees exact reproducibility

Added time savings and reliability due to fast bowl changes

Simultaneous comminution of up to 2 samples
