The especially heavy and solid FRITSCH Disk Mill PULVERISETTE 13 classic line is the ideal instrument for fine grinding of up to 150 kg per hour of hard-brittle and medium-hard solids – even in continuous operation. The maximum feed size per piece is approximately 20 mm edge length, the final fineness is freely adjustable between 12 mm and 0.1 mm. The material to be ground is comminuted by pressure and shearing action between two counteracting grinding disks with coarse interlocking teeth.
For every FRITSCH Disk Mill PULVERISETTE 13 classic line, you need at least one fixed and one movable grinding disk which are available in various materials. Normally, both grinding disks of the same material are selected which must always be harder than the sample to be ground. Especially for metal-free grinding, the Disk Mill PULVERISETTE 13 classic line can be ordered with a complete polymer coating inside of the grinding chamber.
