The compact Pulverisette 1 jaw crusher from Fritsch is suitable for the fast pre-crushing of hard and very hard brittle materials, including ferrous alloys.
Two different models for various feed sizes and sample quantities are available.
The comminution of the sample takes place in the jaw crusher under high pressure between one fixed and one moveable crushing jaw in an enclosed grinding chamber.
The final fineness is 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 Pulverisette 13 disk mill for further comminution.
The Fritsch jaw crushers offer: fast, uniform comminution; a feed size up to 95mm; a final fineness of 1-15mm; crushing jaws and lateral support walls in various steel types, tungsten carbide and zirconium oxide (optimal for RoHS samples and for iron-free pre-crushing); fast cleaning; simple crushing jaw removal; safe and dust-free operation; and adaptable crushing jaw kinematics for higher final finenesses.
The Pulverisette 1 can be combined with the Pulverisette 13, offering a solution for fast, continuous pre-grinding and fine grinding of large quantities of coarse material.
Mounted together onto a rack and connected to each other by a chute, they automatically grind the material from a particle size of up to 95mm to a final fineness of down to 100um.
