The PFC Series Impact Crusher is the latest generation of product from our company’s engineers, designed by integrating the most up-to-date international impact crusher technology, endowing it with world-class quality. It utilizes world-class manufacturing processes and selects the highest-grade production materials. The heavy-duty rotor design, coupled with strict testing procedures, ensures a high-quality rotor. The rotor is the “heart” of the crusher and is the most rigorously inspected component of an impact crusher, playing a crucial role in its operation. Therefore, the company has developed and produced a robust, heavy-duty rotor structure to achieve higher rotational inertia. High-wear-resistant materials and an optimal crushing chamber ensure the exceptional performance of the crusher. The bearing seat adopts an integral cast steel structure, and the unique blow bar fixing device enhances the reliability of the blow bars. The improved adjustment device reduces downtime and maintenance time. The self-contained top-opening device allows for rapid replacement of wear parts, such as the blow bars. Larger and higher-capacity bearings are selected. Analysis is performed on the rotor to ensure stability and reliability.

Application Fields:

Metallurgy, mining, cement, chemical, and other industrial sectors, as well as high-speed road construction, water conservancy projects, and civil engineering fields.

Applicable Materials:

Ores and rocks with a compressive strength not exceeding $300 \text{ Mpa}$ and a surface moisture content not greater than $8\% \text{ to } 10\%$.

Working Principle:

This machine is a crushing mechanism that uses impact energy to crush materials. When the material enters the blow bar action zone, it is crushed by the high-speed impact of the blow bars and is thrown onto the impact device installed above the rotor for secondary crushing. It then rebounds from the impact liner back to the blow bar action zone for re-crushing. This process repeats until the material is crushed to the required particle size and is discharged from the bottom of the machine. Adjusting the gap between the impact rack and the rotor frame can achieve the goal of changing the material particle size and shape. This machine utilizes a spring safety device behind the impact plate, which allows the front and rear impact racks to retreat when non-crushable material enters the crushing chamber, enabling the non-crushable material to be discharged from the machine.

Product Features:

1. Unique Cavity Design Improves Crushing Efficiency: The cavity design causes the material to strike the impact plate vertically, and the material is fed back toward the inlet direction within the blow bar action zone, increasing the number of impacts. This significantly enhances the crushing efficiency and results in a better discharge particle shape. The adoption of a heavy-duty rotor increases rotational inertia and simultaneously raises the material’s linear velocity, improving operational efficiency.
2. Simple and Quick Hydraulic Operating System: The multi-functional full-hydraulic operating system enables full-hydraulic adjustment of the discharge granularity and full-hydraulic top-opening for replacing wear parts. The liners are fixed with high-strength bolts and can be replaced directly from the outside, reducing the labor and time cost of replacing liners. The precision positioning device for the bearing seat reduces the difficulty of positioning the bearing seat during maintenance. The integral blow bar design ensures reliable fixation, and the disassembly and assembly of the blow bars are more convenient and faster.
3. Quality Materials Prolong Service Life: The casing is made of high-strength steel, the blow bars use highly wear-resistant material, the rotor adopts low-temperature, high-strength steel, and international major brands are selected for the bearings. High-quality raw materials form the foundation for extending the crusher’s service life. Thicker liners are used, with bolts rotating from the outside in to prevent the side guard plates from loosening due to bolt wear, ensuring the side guard plates are more fully utilized and significantly prolonging their service life.
4. Precision Machining Ensures Stable Operation: The heavy-duty rotor adopts an integral welding process, which provides high precision and strong impact resistance, reducing current fluctuations during operation. The mating surface between the lower frame and the bearing seat is processed using an integral machining process to ensure machining accuracy. The mating surfaces of the impact plate and impact rack are finely machined and secured using nylon self-locking nuts plus two sets of disc springs, with epoxy resin injected to ensure firm fixation.
