Zenith’s PFW Series Impact Crusher in Open-pit Mining

During the process of open-pit mining, impact crusher often offer unbeatable performances in the secondary or tertiary crushing. Zenith’s PFW series impact crusher also can be widely used in the recycling application. Open-pit mines call for crushers with high crushing ratio. Zenith crusher can meet this particular requirement of open-pit mining. On the other hand, it is very common that mining equipment are frequently broken after a long-term use, however, Zenith engineers have been aware of this problem so that they apply modern techniques to make our impact crushers more suitable for the current situation of open-pit mining. In the open-pit mining, impact crusher can affect the output of quarry to some degree. Whether you adopt any mining method, our crusher can have a wide application as your open-pit mining equipment.

Brief Introduction of Zenith PFW Series Impact Crusher

The PFW series 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 series impact crushers are adopted by heavy-duty rotor design, unique hammer locking system, and interchangeable wearing parts. This series impact crushers provide customers low cost solutions, outstanding performance, good cubical shape, lowest operation cost per ton, and wide materials applications.

Working Principle

This type of impact crusher materials 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.

Advantages of Zenith PEW Series Impact Crusher

1. Bearing adopts the integrated cast-steel structure, which ensures the perfect match with crusher frame. Meanwhile, it greatly increases the radial intensity of bearing seat; 2. Unique fixing device of blow bar brings higher reliability; 3. Reformative adjusting device reduces the overhaul time of machine; 4. Operators can use the automatic open-top device so that they can quickly finish the replacement of wearing parts; 5. Larger bearing specification and higher carrying capacity; 6. Rotor analysis ensures stableness and reliability.
