Impact crushers & impact mills
PB & PM
Impact crusher & impact mill
Impact crushers and impact mills of type PB and PM are universal and, at the same time, economical solutions. The impact crusher achieves very high crushing ratios in both the first and second stage. This results in a wide range of salable, cubical final products. The impact crusher can be repurposed into an impact mill for manufacturing fine grains by inserting a higher machine base and an additional grinding track. This flexible solution allows you to benefit from excellent crushing results and respond to changing project requirements at any time. Impact crushers are traditionally used for rock processing, but the machine is also suitable for recycling applications involving the processing of any kind of brittle-hard material.

Technical systems
Flexible solution for any crushing application
Monoblock casting
- Impact crusher with monoblock casting baffle plates which can be rotated by 180°
- Suitable for limestone and similar types of rock and for concrete recycling
Monoblock casting with wear strips
- Impact crusher with monoblock casting baffle plates with screw-fastened wear strips made of white cast iron
- Suitable for medium-hard rock
Welded construction with wear elements
- Impact crusher with welded baffle plates and screw-fastened wear elements made of white cast iron.
- Well suited for more abrasive types of rock.
Impact mill with additional grinding track
- The additional grinding track located below the rotor axle is used to increase the crushing ratio, improve the particle shape and increase the crushed face count.
- Alternative impact plates (see above) depending on the type of rock.
Replacing impact bars
Based on the task they are performing, the impact bars are made of chilled cast manganese or chrome. The bars are fastened in place using a patented mounting system, which allows the operator to quickly remove and replace them and to use them on both sides. The simple system saves time and requires less physical strength to operate.
1. The rotor is first locked (1), then the impact bar is suspended on a traverse beam (2). After removing the retaining bar (3) by pulling it out from the side, the impact bar can be lifted up.
2. The impact bar is suspended off-center on a cross beam. After lifting up the cross beam [1], the impact bar can be rotated [2].
3. The impact bar automatically rotates to the new position (1).
4. The impact bar can now be lowered (1), which makes it possible to re-install the retaining bar (2). In the next step, the rotor lock is released (3).
Adjusting the gap
Three systems are available for adjusting the gap:
- Mechanical adjustment: via a free-moving thread
- Semi-automatic adjustment: at the press of a button via hydraulic cylinders or motors
- Automatic adjustment: by way of a hydraulic cylinder in combination with a hydraulic load-limiting device. An electronic control unit is used to set and monitor the gap.
