Jaw crusher
Jaw crushers are used for coarse crushing of brittle, medium-hard to hard materials.
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.
High final fineness of up to 90% < 1 mm
Depending on the crusher size, material and set crushing gap, crushing ratios of up to 1:200 can be achieved.
The final fineness obtained is largely determined by the set discharge gap, the stroke and the shredding behavior of the material.
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.
Innovative app control
- Standard Operating Procedures (SOP)
- Display of the set gap width
- Calling up the operating instructions
- Direct spare parts inquiry
- Sample/machine data can be exported as a csv file
- Updateable app and firmware
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
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.
