Jaw crusher

A wide range of sizes for your application, from table-top devices to holding piece sizes up to 240 mm

Different sizes of jaw crushers / single-toggle crushers stand side by side

If you want to save a processing step in sample preparation in the laboratory, our jaw crushers with integrated divider are ideal for this. With our wide range of sizes, we are sure to have the right design for your application.

Areas of application for our jaw crushers

Jaw crushers are used for coarse crushing of brittle, medium-hard to hard materials up to a Mohs hardness of approx. 8.5. Depending on the model, crushing ratios of up to 1:200 are possible.

Our jaw crushers are available in two versions: our laboratory version with integrated control, feed chute and collection container and a version for installation in plants. For the latter, the feed chute, collection container and control unit are omitted.

Crushing & Milling in the jaw crusher takes place in a wedge-shaped crushing chamber between a fixed and a movable crushing jaw. All of our devices impress with many features that make your work easier.

Fixed crushing jaw, which is designed as a door

This enables the crushing chamber to be opened quickly without tools for cleaning, removal of impurities and full inspection of wear on the crusher jaws and side wear plates.

Infinitely adjustable crushing gap

This can be read off via a scale on the housing or in the app. The zero point can be readjusted via the app and on the scale if the crushing jaws are worn.

Reversible overload protection

From size EB 100×80-L

Crushing jaws can be rotated by 180

This doubles the service life of the crusher jaws, as the main wear usually occurs in the area of the smallest crushing gap.

Suction connection

Via connection flange in the non-intrusive feed chute.

Low-maintenance and lubricant-free Crushing & Milling

With the sealed and lifetime-lubricated bearings up to size EB 200×125-L.

Low-contamination Crushing & Milling with crushing jaws made of

Hard cast steel, stainless steel, tungsten carbide or zirconium oxide

Optionally available base frames

for driving under the jaw crusher with pallet truck/forklift truck

Turntable with 5 containers

to divide the sample quantity into 3 times 1:4 and 2 times 1:8

Jaw crusher with integrated divider - the individual containers are removed from the opened dividing device

If you have any additional requirements, e.g. a base frame that can be driven under with a pallet truck, continuous material feed, etc., please contact us. – please contact us.

Operating behavior & mechanical features

Crushing & Milling in the Jaw crushers takes place in a wedge-shaped crushing chamber between a fixed and a movable crushing jaw. In the upper suspension, the movable crusher jaw is driven by an eccentric shaft and supported in the lower area by a continuously lockable eccentric shaft. Due to this special geometry, the crusher jaw performs an elliptical circular movement both in the upper suspension and at the discharge gap. Due to this sequence of movements, the crushing chamber is reduced with each rotation, which leads to material crushing, but is also enlarged so that material is loosened up and can slide down. The wedge-shaped form of the crushing chamber and the stroke specified by the eccentric shaft allow the material to slide deeper into the crushing chamber with each revolution until it can leave the crushing chamber crushed according to the set gap.

The arrangement of the movable crushing jaw enables both a high throughput rate and a high achievable final fineness, whereby this depends not only on the design but also on the size of the set discharge gap on the crusher and the crushing behavior of the crushed material.
