Description

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 100 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. WORKING PRINCIPLE 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.
