For fast and effective pre-crushing of hard, very hard brittle materials even ferrous alloys.
Max. feed size: 95 mm
Areas of application
Mining and metallurgy, chemistry, geology and mineralogy, glass industry, ceramics, rocks and soils.
Method of operation
The powerful comminution of the sample takes place in the Jaw Crusher under high pressure between one fixed and one movable crushing jaw in an enclosed grinding chamber. The final fineness is easily set from the outside with the 10-stage adjustable gap width between the crushing jaws. The ground sample automatically falls downward – into a drawer for batchwise comminution or via a chute into a larger collection container for continuous operation or directly into a FRITSCH Disk Mill PULVERISETTE 13 classic line for further comminution. Additional information about the instrument combination:
Jaw Crusher PULVERISETTE 1 and Disk Mill PULVERISETTE 13

Material data for crushing jaws and support walls
Material | Main component of the material | Density g/cm³ | Abrasion resistance | Used for grinding material |
Tempered steel | Fe – Cr | 7.9 | Good | Brittle, very hard samples |
Stainless steel | Fe – Cr - Ni | 8 | Fairly good | Medium-hard, brittle samples |
Chromium-free steel | Fe | 7.9-8 | Good | Medium-hard samples |
Manganese steel | Mn - Fe | 7.9-8 | Good | Hard, brittle samples |
Hardmetal tungsten carbide | WC | 14.05 | Very good | Hard, abrasive samples, |
Zirconium oxide ¹ | ZrO2 | 5.9 | Good | Medium-hard, brittle samples, iron-free grinding |
Aluminium | Al | 2.7 | Fairly good | Medium-hard, brittle samples, iron-free grinding |
In normal cases, crushing jaws and support walls of the same material are used. Since the side walls are not subject to any large stresses, the standard equipment of hardened steel side walls can often be retained.
¹)Crushing jaws of zirconium oxide are only suitable for crushing ceramic materials, minerals, etc. and never for hard-tough samples such as metals
