Quick Details
PFY Series Impact Crusher Machine is designed and developed by our company by introducing latest advantages of many domestic similar products. It adopts the heavy type rotor structure, high capacity crushing chamber, high wear-resisting alloy plate hammer, heavy impact-resistance impact liner, multi-point hydraulic adjustment device and hydraulic opening device. These advantages ensure following features: large crushing capacity, high crushing effect, big feed size, fine discharge size, big crushing ratio and good products shape.
★PFY Hydraulic Impact Crusher is widely used in secondary and fine crushing of sand and aggregate industry for low-abrasive rocks.
Working Principle
Impact Crusher Machine is a kind of crushing machine that uses the plate hammer of the high speed rotating rotor to crush the materials at a high impacting crushing force. When the materials get into the action area of plate hammer, they are crushed by the hammer at a high speed. The crushed materials are thrown to the impact plate along the tangential direction to crush again. Then they are rebounded from the first impact plate to the action area of the plate hammer and enter into the second impact plate to repeat the above process. During this process, materials also crash with each other. This process will proceed repeatedly until the material are crushed to the required granularity, and then discharged from the clearance between impact plate and plate hammer.

Features
1. The special design of the heavy rotor structure provides extremely high rotary inertia and impact crushing force for the hammerhead to improve the first-time crushing pass rate.
2. The special design of the hammerhead makes its crushing profile remain unchanged during the service life to ensure the stability of the product gradation.
3. The spare parts adopt a modular design, which ensures high interchangeability, easy control and low cost.
4. The rear frame and access door can be opened at the same time to replace all the worn parts, which improves the work efficiency greatly.
Application
Application Fields: water conservancy and hydropower, construction, highway and high speed railway, etc.
Applied Material: aggregates with compressive strength >300MPa, Moh’s hardness > level 6.
