Achieving top crushing results

Impact crusher & impact mill

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.

  • 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.

Step 1

Step 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.

Step 2

Step 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].

Step 3

Step 3

The impact bar automatically rotates to the new position [1].

Step 4

Step 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.

Success stories

It’s all about the purity: high-grade aluminum concentrate from incinerator bottom ash

February 2021
French waste recycling company Norval has been using an impact mill (PM) from BHS-Sonthofen for aluminum processing in the final process step since June 2019. The sturdy machine frees the pre-sorted aluminum fraction from the waste incineration system from undesired adhesions, thus reliably ensuring that a high-grade aluminum concentrate is obtained.

DHZ AG – Extracting concentrated metals from incinerator bottom ash

July 2016
DHZ AG operates a modern recycling center in Lufingen in the Swiss canton of Zurich. The facility focuses on processing incinerator bottom ash (IBA). BHS-Sonthofen supplemented two existing IBA processing plants with an additional plant that extracts high-quality, heavy and light non-ferrous metal fractions from the coarse concentrate generated upstream. These are of such high quality that they can be sold directly to smelters or to industrial customers.

Recycling gypsum plasterboard: Turning construction waste into a chemically pure resource

October 2020

EU regulations, coal phase-out and the construction boom are among the many reasons these days for making the recycling of gypsum highly attractive. However, the process needs to be cost-efficient. BHS-Sonthofen developed a process that entails two crushing stages. This even makes it possible to recycle any adhering impurities.
