PF stone impact crusher overview
The fied-proven PF series stone impact crushers will give you years of dependable and profitable service with its features of unique hammer locking system, reasonable design and renowned performance. The PF hydraulic stone impact crushers of European style also has benefits of high reduction ration which is up to 20:1, cubic product with high crush count, selective crushing by speed and breaker plate adjustment.
The PF series stone impact crushers is the ideal crushing machine for demolition contractors, quarry operators and recycling operations requiring a high throughput machine. The PF stone impact crushers are available in 8 low maintenance, minimum downtime models. The processing capacities range from 70-120t/p to 240-400t/h, capable of producing a high quality end product.
The PF series stone impact crushers are based on a revolutionary modular, non-welded frame construction to offer owners the highest possible fatigue strength, excellent reliability and numerous mounting possibilities, a special heavy-duty rotor to obtain a higher inertia. With crushing chamber made of high wear-resistant material and ultra-fine size operations, the two-crusher crusher can greatly simplify the operation process of big and medium sized materials.

Features of PF stone impact crusher
1. Adopting world-class manufacture technique, selecting high-grade raw material.
2. High quality rotor with heavy design and strict inspection.
3. 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.
4. Unique fixing device of blow bar brings higher reliability.
5. Reformative adjusting device decrease the time of machine stop and overhaul.
6. Self-own open-top device can quickly finish the replacement of wearing parts.
7. Larger bearing specification and higher carrying capacity.
8. Rotor analysis ensures stableness and reliability.
working principle of PF stone impact crusher
It uses the impact power to crush materials. When being fed into the blow bar function area, the materials fall into breakage because of high-speed impact and get the second breakage after being thrown to the impact plate installed above rotor, and finally rebound to the blow bar area to get repeat crushing. The process repeats until materials are broken to the required size and then discharged from the bottom of the crusher. We can get our required size of the end products by adjusting the clearance between the impact frame and the rotor frame.
Application of PF stone impact crusher
The PF stone impact crushers is mainly applied to metallurgy, mine, cement, chemical plant, fireproof material, porcelain industries and so on. It is widely used in expressway, water conservancy project, construction gravel, machine-made sand areas. And it is perfectly suitable for primary, secondary, tertiary crushing of soft and mid-hard rocks and ores.
