The FRITSCH Disk Mill PULVERISETTE 13 premium line is designed for efficient fine grinding of hard-brittle to medium-hard solids. It features automatic locking of the collecting vessel and grinding chamber for enhanced safety, and motor-driven grinding gap adjustment with a digital display for easy, precise operation. The mill uses pressure and shearing forces between two counter-rotating grinding disks with coarse interlocking teeth to comminute materials. Ground samples fall automatically through the preset grinding gap into the collection drawer. The final particle size can be reproducibly controlled by adjusting the digital grinding gap. Ideal for medium particle sizes, it is widely used in mining, metallurgy, ceramics, glass, soil research, and related industries. The clear display shows all parameters for convenient monitoring and control during operation.
