The relatively large throughput enables it to be used in the pilot scale or in the small size production, for example slag disintegration for the reclamation of precious metals
The Pulverisette 13 disk mill is Fritsch's recommendation for all processing laboratories with a continuous delivery of brittle to very hard materials for batch or continuous fine grinding.
The maximum feed particle size is approx 20mm edge length.
The fineness attainable (d50) is down to approx 12mm (largest gap width) or 0.1mm (smallest gap width).
The maximum throughput of 150kg/h depends on the gap setting and the hardness of the sample.
The relatively large throughput enables it to be used in the pilot scale or in the small size production, for example slag disintegration for the reclamation of precious metals.
The material to be ground is crushed between two counteracting grinding disks with course radial toothing on the inside as a result of compressive and shearing stresses.
The staged toothing means that the material is preground in the inner chamber of the grinding disks before being finely ground in the outer chamber.
The gap width between the two grinding disks is set from the outside - and also during operation - and determines the fineness of the end product.
Typical fields of application include mining and steel industries, ores, coal, coke, slags, ceramics, steatite, sintered ceramics, electrotechnical porcelain, fire-proof clay, rocks and soils, bauxite, slags, quartz, clinker, gypsum, chalk, dried soil samples, sewage sludge, hydrological sediments, and drilling cores.
