Method of operation
  • The material to be ground is comminuted by pressure and shearing action between two counteracting grinding disks with coarse interlocking teeth. The ground material automatically falls down through a pre-set grinding gap into the collection drawer. The desired final fineness can be defined reproducibly by simply adjusting the digital setting of the gap width.
  • It’s this easy: Simply press the button to lock the grinding chamber, use the plus/minus buttons on the digital display to set the grinding gap and grinding time reproducibly and with accuracy to the second, fill in the sample into the funnel and start the grinding process.
  • For especially fast and continuous premium pre- and fine-grinding of large quantities of coarse material, the Disk Mill PULVERISETTE 13 premium line can be combined with the Jaw Crusher PULVERISETTE 1 premium line
