Jaw crusher for powerful pre-crushing of hard and very hard brittle materials

The unit is ideal for pre-crushing in the areas: Mining and metallurgy, chemical industry, geology and mineralogy, glass and ceramics industry and soil research.

The jaw crusher PULVERISETTE 1 premium line offers extra powerful premium pre-crushing:

Up to 3 kW drive power for processing higher throughput in shorter times

Feed size up to 95 mm, final fineness 0.3 – 15 mm

Clean Design for extra-fast cleaning

Zero-point and grinding gap adjustment with millimetre accuracy

Extremely robust, for even ferrous alloys

Funnel folds away completely for large sample quantities

Extra low noise and dust-free operation

Variable crushing jaw kinematics for higher final fineness

Only the PULVERISETTE 1 premium line has a completely accessible grinding chamber, because the fixed crushing jaw is mounted in a guide and can be removed with a single motion. Also the movable crushing jaw can be swivelled up and locked there. The advantage: A completely accessible grinding chamber for fast, efficient and safe cleaning.

On the PULVERISETTE 1 premium line, the zero-point adjustment which can be calibrated, is connected with a progressive grinding gap adjustment. With a single motion, the double eccentric can be used to precisely set the grinding gap in millimetre steps – and for the finer particle range, in correspondingly smaller steps.

The FRITSCH jaw crusher PULVERISETTE 1 premium line offers easy, fast and convenient change of the kinematics without altering the gap adjustment with one single motion. Operators can select between the settings specified on the instrument: “Eccentricity normal” provides the fastest possible comminution due to the approximately circular oscillation of the crushing jaws or “Eccentricity small” to achieve a narrow particle size range through up and down shearing motions. The advantage: optimal adaptation to the breaking characteristics of the respective sample.

Operators can combine the jaw crusher with the premium version of the FRITSCH disk mill PULVERISETTE 13 for efficient fine-grinding. The advantage: optimal continuous pre- and fine-grinding with a feed size of up to 95 mm down to a final fineness of 0.05 mm in a single step with integrated riffle sample splitter.

All these innovations make daily work easier and more time-saving for the operators.
