Fast and effective pre-crushing of hard and very hard brittle materials

FRITSCH Jaw Crushers

The compact pre-crusher: Jaw Crusher PULVERISETTE 1 classic line Ideal as the classic workhorse for pre-crushing of brittle materials in the areas of mining and metallurgy, chemistry, geology and mineralogy, glass industry, ceramics industry, rocks and soils.

Choose according to your tasks between two different models for various feed sizes and sample quantities:The compact FRITSCH Jaw Crusher PULVERISETTE 1 classic line is the ideal instrument for fast and effective pre-crushing of hard and very hard brittle materials – even ferrous alloys are no problem for this instrument!

Jaw Crusher model I:

Max. feed size: 60 mm, max. continuous throughput: 140 kg/h

Jaw Crusher model II:

Max. feed size: 95 mm, max. continuous throughput: 200 kg/h

Powerful pre-crushing

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.

Your advantages with the FRITSCH Jaw Crushers:

  • Very fast, uniform comminution
  • Final fineness 1–15 mm, gap width adjustment from the outside
  • Crushing jaws and lateral support walls are available in various steel types, tungsten carbide and zirconium oxide – to avoid undesired contamination due to material abrasion and is optimal for RoHS-samples and for metal-free pre-crushing
  • Extremely robust even for very hard materials
  • Especially simple crushing jaw removal
  • Safe and dust-free operation

Extremely fast and easy cleaning

The especially simple crushing jaw removal takes only seconds and requires only two hand motions to ensure particularly simple cleaning – fast and thorough. This saves time and energy und offers effective contamination protection for your samples.

Flexible kinematics – Perfect sample adaption

The kinematics – in other words, the movement between the movable and fixed crushing jaws – of the FRITSCH Jaw Crusher PULVERISETTE 1 classic line can be easily adapted to the breaking characteristics of the respective sample: Select the upward and downward movement of the movable crushing jaw relative to the fixed one in order to receive a sample in a narrow particle size range. For a fast comminution, please select the nearly circular motion.

An extra PLUS

Test the FRITSCH Jaw Crushers!Both models of the FRITSCH Jaw Crushers PULVERISETTE 1 classic line can be combined with the Disk Mill PULVERISETTE 13 classic line – 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 95 mm to a final fineness of down to 100 μm – fast, easy and effective in a single step!
