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.

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.

Blow bar replacement

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 width

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.
