The Compact Pre-Crusher

The compact Fritsch Jaw Crusher PULVERISETTE 1 is the ideal instrument for fast and effective precrushing of hard and very hard brittle materials – even ferrous alloys are no problem for this instrument. Customers choose according to their tasks: two different models for various feed sizes and sample quantities are available.

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 for further comminution.

Advantages of the Fritsch Jaw Crushers include: very fast, uniform comminution; feed size up to 95mm, final fineness 1–15mm; crushing jaws and lateral support walls are available in various steel types, tungsten carbide and zirconium oxide – optimal for RoHS-samples and for iron-free pre-crushing; extremely fast and easy cleaning; extremely robust even for very hard materials; especially simple crushing jaw removal; safe and dust-free operation; and adaptable crushing jaw kinematics for higher final fineness.

The Jaw Crusher PULVERISETTE 1 can be combined with the Disk Mill PULVERISETTE 13 – the ideal solution for fast, continuous pre- and fine-grinding particularly 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 100μm – fast, easy and effective in a single step.
