SUCESSFUL PROJECT
PFW Impact Crusher
The PFW impact crusher is also called European style impact crusher, which is very suitable for open-pit crushing in quarries. During the process of mining, impact crusher often offer unbeatable performances in the secondary or tertiary crushing. 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.PFW series mining impact crusher are designed for crushing ores and rocks with partical size less than 110-400mm and compression strength no more than 500Mpa. mining impact crusher has a feature of big crushing ratio, high-effeciency crushing, cubic shape, selectable crushing and etc.
Working Principle of PFW Impact Crusher
This impact hammer crusher crushes materials with impact force. When the materials enter the blow bar area, they are crushed due to the high-speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crush. Then the materials will be shot back to the blow bar again for the third crush. 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-weigh 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.
Products Features
- Adoption of the world-class manufacturing processes and selection of the most high-end raw materials.
- Heavy type rotor design and strict testing method to guarantee high quality rotor.
- Adoption of the Integral cast steel structure on bearing seat makes it matches well with the crushing frame and increases the radial strength of it, while the divided design does not has this advantage.
- The unique fixing device for hammers,make it more reliable.
- The hydraulic adjusting device makes the maintenance easier and less.
- Self-equipped open-top device can quickly complete the replacement of wearing parts such as the hammer.
- Selection of the bearing with larger size and higher load.
- Finite element analysis on the rotor to ensure its performance more stable and reliable.
