Picocross laboratory pin mill

The Picocross counter-rotating pin mill opens up new possibilities in the laboratory for the fine grinding of soft to medium-hard materials. The interaction of counter-rotating pin discs generates high impact energies for efficient comminution and reproducible results. Integration into the Picoline platform is quick and straightforward.

Principle of operation

• The ground material is dosed into the centre of two counter-rotating pin discs and crushed by impact against the grinding pins.
• The high shear rate of the counter-rotating discs enables particularly intensive stressing of the particles.
• After passing through the grinding zone, the ground material enters the mill housing and exits the mill by gravity.
• The rotation creates an air flow from which the ground material is separated in a filter.
• The grinder is adjusted by the speed of the two rotors and the feed rate.
