MD-3000 Laboratory Disc Refiner

The MD-3000 is a disc refiner widely used for refining studies of pulps in the QC (quality control) and R&D (research and development) of pulps, papers and boards.  There are 6 different disc options to select from.  


The MD-3000 is a disc refiner widely used for refining studies of pulps in the QC (quality control) and R&D (research and development) of pulps, papers and boards.

Its high capacity and sturdiness allow customers to use it also as the main refiner in small-sized production lines of special papers.  The MD-3000 is supplied with one pair of refining discs according to customers option.

Six Refining Disc Options:
