Laboratory Disc Pulverizer Pulverisette 13

The Laboratory Disc Pulverizer Pulverisette 13 is designed for batch or continuous fine grinding of hard-brittle to medium-hard solids.

The Disc Pulverizer Pulverisette 13 is designed for batch or continuous fine grinding of brittle and very hard materials. The maximum feed particle size is approx. 20 mm edge length. The fineness attainable (d50) is down to approx. 12 mm (largest gap width) or 0.1 mm (smallest gap width). The maximum throughput of 150 kg/h depends on the gap setting and the hardness of the sample. The relatively large throughput enables it to be used in both pilot scale and small size production, for example: slag-disintegration for the reclamation of precious metals. Applications: mining and metallurgy, ceramics industry, rocks and soils, glass industry, soil research.

Maximum feed size: 20 mm (3/4’’)
Final fineness: 0.1 to 12 mm (depending on gap setting)
Maximum capacity: 150 kg/h
Grinding materials: Hardened cast steel, manganese steel, tungsten carbide, zirconium oxide
Dimensions (WxDxH): 44x87x40 cm (17x34x16’’)
Weight: 140 kg (308 lbs.)

The material is pulverized 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 pan. The desired final fineness can be defined from the outside by changing the gap width. The Disc Mill Pulverisette 13 can be combined with the Jaw Crusher Pulverisette 1 for a size reduction from 95 mm down to 150 µm in a single pass.

  • Simple operation, fast, easy cleaning
  • Precision setting of the final fineness even during grinding
  • High service life due to generously dimensioned bearings
