FRITSCH Planetary Ball Mills – high-performance all-rounder in routine laboratory work
The Planetary Mill PULVERISETTE 5 premium line with 2 grinding stations is the ideal mill for fast wet and dry grinding of hard, medium-hard, soft, brittle and moist samples as well as for mechanical alloying, mixing and homogenising of larger sample quantities with reliable results down into the nano range – and an absolutely secure automatic clamping of the grinding bowls.
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. The grinding bowls reach twice the speed of the main disk during this process.
Due to the extra strong 2.2 kW drive power and centrifugal acceleration up to 64 g and up to 800 rpm (rotational speed of the bowl 1,600 rpm) are high-performance grindings down into the nano range possible.
FEATURES
• Extra strong 2.2 kW drive power and extremely high centrifugal acceleration up to 64 g and up to 800 rpm (rotational speed of the bowl 1,600 rpm)
• Maximum operational safety due to ServoLOCK clamping of the grinding bowls
