Impact crusher & impact mill (PB & PM)

Impact crushers and impact mills (HSI) are universal and, at the same time, economical solutions. The BHS 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 finer 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.

Benefits at a glance:

  • Excellent crushing performance
  • Powerful rotors and heavy-duty impact plates
  • Large feed opening, quick and simple blow bar replacement
  • Maintenance-friendly design
  • Optimized wear parts

Highlights

RZ_BHS_Prallmühle1010__v2.psd

Powerful rotors

There are a variety of rotors available depending on the specific task at hand. The BHS rotors feature a durable, welded design. All surfaces subject to wear are fitted with replaceable wear parts. The impact bars are replaced from above. Plus, they can be removed quickly and easily thanks to their patented mounting system.

Robust impact plates

Depending on the application, the impact bars are made of heavy-duty monoblock cast iron or a welded steel structure with replaceable wear elements. The impact bars also easily handle coarser feed material and can be optimally configured for the relevant shredding task. Impact plates are supported by durable, maintenance-free spring units.

Large feed opening

Despite their compact dimensions, all BHS impact crushers and impact mills have a very large feed opening. This prevents material jams and allows for optimum use of the crushing chamber even when feeding material of the maximum allowable size. As a result, high throughput rates and excellent crushing results are achieved.

Maintenance-friendly design

BHS machines feature a durable and compact design. The two-part removable enclosure provides easy access for maintenance work, even in very tight spaces.

Optimized wear parts

The impact chamber liner consists primarily of interchangeable components, which reduces the number of parts you need to keep in stock. In addition to that, the liner parts can also be easily replaced.

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.

PB-PM_Prallraum_Mahlbahn_PM0806_122013.ai

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 cross beam [2]. After removing the retaining bar [3] by pulling it out from the side, the impact bar can be lifted up.

BHS_Schlagleistenwechsel_v1_0001.psd

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].

BHS_Schlagleistenwechsel_v1_0003.psd

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

BHS_Schlagleistenwechsel_v1_0005.psd

4. The impact bar can now be lowered (1) and the retaining bar re-installed (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.
