The PFS Series Impact Crusher represents a brand new breakthrough by our company’s technical engineers in the field of mining crushing equipment. The maximum feed size can reach $1000 \text{ mm}$. Compared with traditional impact crushers, it significantly increases the crushing ratio. A specialized adjustment device allows for free switching between the primary crushing and secondary crushing modes. This not only preserves the unique excellent particle shape advantage of the impact crusher but also greatly increases the output, making it the most advanced crushing equipment in the current crushing equipment industry.
Application Fields:
Hydropower, highway construction, artificial sand and aggregate production, ore crushing, and other industries.
Applicable Materials:
Limestone, granite, marble, basalt, iron ore, river pebbles, shale, bluestone, coal, cobble, construction waste.
Working Principle:
The impact crusher is a crushing machine that uses impact energy to crush materials. During operation, the motor drives the rotor to rotate at a high speed. When the material enters the action area of the blow bar, it is struck and crushed by the blow bars on the rotor, then thrown onto the impact device for secondary crushing. It then rebounds from the impact liner back to the blow bar action area for re-crushing. This process repeats, and the material, from large to small, enters the first, second, and third impact chambers for continuous crushing until it is crushed to the required particle size and discharged from the outlet. Adjusting the gap between the impact rack and the rotor can achieve the purpose of changing the final product particle size and shape.
Product Features:
- Large Feed Size and High Crushing Ratio:The maximum feed size of the PFS Impact Crusher can reach $1000 \text{ mm}$. Through a heavy-duty rotor design and a crescent-shaped blow bar structure, it achieves vertical impact on the material, which significantly enhances the crushing ratio.
- Flexible Crushing Mode Switching:The equipment is fitted with a specialized adjustment device that allows for free switching between primary and secondary crushing, adapting to different material properties and finished product requirements. For instance, in construction waste recycling projects, adjusting the gap between the impact rack and the rotor can achieve both efficient coarse crushing and ensure the final aggregate’s cubical shape.
- Excellent Final Product Shape:Adopting the multi-chamber crushing principle, the material is repeatedly impacted and crushed between the rotor, impact plates, and liners. The final product is cubical with no surface cracks and has a high bulk density, making it particularly suitable for engineering fields like expressways and railways that have strict requirements for aggregate shape.
- Wear-Resistant Materials and Structural Design:The blow bars are made of high-chrome cast iron and are specially heat-treated for impact resistance and wear resistance. The rotor uses a wedge block to secure the blow bars, ensuring firmness even under high-speed operation and making replacement convenient. The bearing housing is an integral cast steel structure that fits tightly with the frame, providing strong load-bearing capacity and featuring dustproof and waterproof functions, thereby extending the service life of key components.
- Quick Maintenance and Low Downtime:The equipment features a split-body (mid-open) structure and a hydraulic top-opening device, allowing the frame cover to be quickly opened. This enables the replacement of wear parts such as blow bars and impact plates without disassembling complex components, reducing inspection and maintenance time by over $30\%$.
