Addressing the project's stringent requirements for the cleanliness of finished aggregates, the PF1214, with its unique crushing chamber design, effectively reduces excessive stone powder content when crushing high-hardness materials such as basalt. This advantage provides high-purity raw materials for subsequent concrete mixing or asphalt mixing processes, significantly enhancing the market value of the final product.
Solution Configurations:
• Medium-hardness aggregate solution: PE jaw crusher + PF1214 impact crusher + 3YK2460 vibrating screen
• High-hardness material solution: PE jaw crusher + HPC cone crusher + PF1214 impact crusher (shaping section) + multi-layer vibrating screen
Four Major Application Advantages:
1. Excellent Particle Shape: High cubic yield and extremely low needle-like and flaky content, perfectly matching high-end building aggregate standards.
2. High Efficiency and Energy Saving: Optimized rotor dynamics design, processing capacity reaches 80-180t/h, with overall energy consumption reduced by 15%-20%.
3. Easy Maintenance: Standard configuration includes a hydraulically assisted opening device, allowing for quick replacement of the hammer and liner, significantly reducing downtime in extremely cold regions.
4. High Versatility: Not only capable of crushing limestone, granite, and basalt, but also an environmentally friendly tool for producing recycled aggregates from construction waste.
Frequently Asked Questions about PF1214 Impact Crusher
1. What are the pairing principles for PF1214 with jaw crushers and cone crushers?
A: Follow the principle of "crushing before grinding, pulverizing before grinding":
For soft/medium-hard rock production lines (e.g., limestone): Jaw crushers are used for primary crushing, and PF1214 directly performs secondary/final crushing. This results in a shorter process, lower investment, and better particle shape.
For hard rock/highly abrasive materials (e.g., granite, basalt): Jaw crushers + cone crushers are used for intermediate crushing and unloading, and PF1214 performs tertiary shaping crushing. This scheme protects the impact crusher hammers from excessive wear and utilizes the impact principle to reshape the flaky particles discharged from the cone crusher into cubic particles, achieving the dual goals of "high efficiency + high-quality particle shape".
2. The capacity range of 100-180t/h is quite large. How do I determine the specific output?
A: Actual production capacity depends on three main variables:
1) material properties (hardness, mud content, moisture);
2) feed particle size distribution;
3) finished product discharge particle size requirements.
Taking medium-hard limestone (crushing index ≤ 0.1 kWh/t) as an example, the production capacity can reach its upper limit when the discharge port is adjusted to 35 mm; if processing hard basalt and controlling the discharge to ≤ 25 mm, the production capacity will be closer to the lower limit. We recommend that you provide specific working condition samples so that our process engineers can provide an accurate production capacity estimate through calculation simulation or on-site benchmarking projects.
3. Can the PF1214 impact crusher operate stably in the harsh environment of Russia?
A: Yes. The key bearings of the PF1214 series impact crusher use low-temperature resistant grease and a special sealing structure, allowing normal start-up and operation in environments as low as -40℃. The hydraulic opening system has also been optimized for extremely cold conditions, ensuring that maintenance operations are not affected by low temperatures. Our actual operating data from multiple sites in Russia has verified its reliability.
