PULVERISETTE 1

premium line

The extra powerful premium pre-crusher

The most powerful FRITSCH Jaw Crusher ever: up to 3 kW drive power ensures the Jaw Crusher PULVERISETTE 1 premium line for an exceptionally high throughput – batchwise or continous – during the pre-comminution of hard and very hard brittle materials even hardest ferrous alloys. For easy cleaning, the crushing jaws can be completely swivelled out or removed. The integrated dust exhaust channels provide optimal working conditions.
The FRITSCH Jaw Crusher PULVERISETTE 1 premium line is ideal for a max. feed size of 95 mm and a max. continuous throughput of up to 250 kg/h depending on the material and gap setting.

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 gap adjustment is defined with millimetre accuracy from the outside, simply by adjusting the distance 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 premium line for further comminution.

• Throughput of up to 250 kg/h, max. feed size 95 mm, final fineness 0.3-15 mm
• Robust due to a solid steel frame for the most demanding applications
• Clean Design: smooth surfaces of the grinding chamber enable an easy and thorough cleaning
• Completely accessible grinding chamber for cleaning since crushing jaws are completely swivelled up or completely removable
• Dust-free operation due to integrated dust channels and by the connection of dust exhaust system controlled directly via the instrument
• Outstanding noise reduction due to side walls insulated with foam for significantly quieter operation
• Especially safe as drawer and grinding chamber lid lock automatically
• Grinding gap adjustment with millimetre accuracy via double eccentric for the finer particle range, in correspondingly smaller steps
• Calibratable zero-point adjustment: compensating wear on the fixed and movable crushing jaws and for easy precise re-adjustment after turning or replacing the crushing jaws
• Unique crushing jaw kinematics with fast change without altering the gap adjustment adaptable to the breaking characteristics of the sample
• Automatic short change of the direction of rotation in order to quickly free up any blockages during comminution
• Automatic adjustment of the correct direction of rotation for optimal results for the three-phase versions
• Funnel folds away completely for large sample quantities – easy to access and easy to fill
• Visible grinding chamber with extremely heavy-duty plexiglass cover
• Combinable with the Disk Mill PULVERISETTE 13 premium line
• Steel crushing jaws available with a grooved surface for achieving a higher share of fine particles
• Crushing jaws and support walls are available in different materials for adapting to your application – even for chromium- and metal-free pre-comminution

Completely accessible grinding chamber
The fixed crushing jaw mounted in a guide and can be removed with a single motion. And the movable crushing jaw can be swivelled up and locked there. Your advantage: A completely accessible grinding chamber for fast, efficient and safe cleaning.

Progressive gap adjustment
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

Calibratable Zero-point adjustment
To remove the lateral support walls mounted in the guide of the PULVERISETTE 1 premium line, simply loosen the screws and pull the support walls up and out of the guide.

Lateral support walls are especially easy to remove
To remove the lateral support walls mounted in the guide of the PULVERISETTE 1 premium line, simply loosen the screws and pull the support walls up and out of the guide – that’s it!

Both crushing jaws are especially easy to remove
To turn or replace the fixed crushing jaw simply pull out the retaining bolt; the jaw is held securely for simple removal. Now, take the turned around or replacement crushing jaw and slide it back into the guide as far as it will go and push-in the retaining bolt. As a result of its fastening mechanism, the movable crushing jaw can be just as quickly and safely turned around or replaced: Simply lift it, fix it horizontally, and remove it.
Your advantage: double service life due to simple turning of both of the crushing jaws - and anytime fast and simple exchange of the crushing jaws.

Unique kinematics with fast change: Only the FRITSCH Jaw Crusher PULVERISETTE 1 premium line offers easy, fast and convenient change of the kinematics without altering the gap adjustment. Simply 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. Choose “Eccentricity small” to achieve a narrow particle size range through up and down shearing motions. As a result, the PULVERISETTE 1 premium line can be adapted to the breaking characteristics of the respective sample with one simple motion.

Configure your Jaw Crusher PULVERISETTE 1 premium line exactly to your specific application

The crushing jaws and support walls of the FRITSCH Jaw Crusher PULVERISETTE 1 premium line are available in 6 different materials to prevent undesired contamination due to material abrasion. The standard version is equipped with fixed and movable crushing jaws as well as lateral support walls made of tempered steel.
