Installation method: The PFW series European-style impact crusher must be installed on a solid concrete foundation. The foundation must withstand the weight of the equipment and the enormous impact load during crushing operations. During installation, it is necessary to ensure that the foundation level meets the requirements, and anchor bolts should be tightened according to torque specifications. After positioning the equipment, adjust the level to ensure the rotor is parallel to the motor shaft. The motor and crusher are connected via a V-belt or direct drive, and it is necessary to adjust belt tension or alignment accuracy to ensure smooth transmission. The impact frame adjustment device must be calibrated smoothly to ensure the discharge gap meets the finished product size requirements. The equipment comes with a top-opening device, which allows rapid replacement of wear parts like blow bars, reducing downtime for maintenance. After installation, perform a no-load test run to check whether the rotor spins smoothly, and whether there is any abnormal vibration or noise, and confirm that the gap between the blow bars and impact plates is uniform. During the load test run, gradually increase the feed amount, observe the crushing effect and motor current, ensuring it does not exceed the rated current. A dust removal system should be installed to reduce dust pollution. A central control system can be equipped for online monitoring and automatic control.

Note: The PFW series European version impact crusher is divided into two-chamber (II) and three-chamber (III) series. The two-chamber type is suitable for coarse and medium crushing, with a large feed opening, allowing a maximum feed size of up to 700mm; the three-chamber type is suitable for medium and fine crushing, producing finer finished material with better particle shape. Users can choose based on the type of raw material, scale, and finished product requirements. The hammer and impact plates are core wear parts; for highly abrasive materials, it is recommended to choose high-chromium alloy materials. The impact crusher is not suitable for handling ultra-high hardness materials or materials with excessive moisture and high stickiness. In explosive environments, explosion-proof motors must be selected.
