The PFW impact crusher is also called European style impact crusher, often used in the secondary crushing and fine crushing. It is very suitable for open-pit crushing in quarries. PFW impact crusher is adopted by heavy-duty rotor design, unique hammer locking system, and interchangeable wearing parts.
Impact crusher often offer unbeatable performances in the secondary or tertiary crushing during the process of mining. PFW impact crusher also can be widely used in the recycling application. Modern mining industry calls for crushers with high crushing ratio. However, PFW series impact crushers can meet this particular requirement. On the other hand, it is very common that mining equipment are frequently broken after a long-term use, however, engineers from our company have been aware of this problem so that they apply modern techniques to make our impact crushers more suitable for the current situation of mining industry.
This PFW impact crusher deals with materials through the impact force. When the materials enter the cavity, they are crushed by the high-speed impact of the blow bar. So they are thrown into the impact plates on the rotor for secondary crushing. Then the materials will be shot back to the blow bar again for the third crushing.
This process repeats until the materials are crushed to the required size and discharged from the lower part of the machine. The size and shape of the finished powder can be changed by adjusting the gap between the impact rack and rotor support. The machine employs self-weight security device in its back frame. When other objects enter the impact cavity, they will be forced out of the machine by the impact rack in the front and back of the machine.
