For the pilot beating of pulps in QC and R&D laboratories

The Jakro JK-21 laboratory beater has six sets of beating units, mounted on a horizontal, revolving table. This performs a planetary movement around the central shaft to ensure a perfectly homogenous beating of the sample.

Each unit consists of a beating box, a grooved roll and lid, all made from hard bronze. This ensures reliability and repeatability. The compact design and rugged, precise construction guarantees long, safe operating periods and a minimal need for maintenance.

Applicable standards:· DIN 54360
