In feed production lines, the hammer mill is a critical machine. It has a direct impact on grinding efficiency, product quality, and operating costs.Proper replacement of wear parts such as hammers and screens is necessary to maintain the equipment’s optimal performance. Shanghai Yuanyuda International Trade Co., Ltd. applies several procedures to ensure that your feed machinery provides the same high-quality results.Specializing in complete feed machinery solutions, the company provides expert advice for 1.5-20 t/h aquatic feed production lines and 200 t/h livestock and poultry feedlines.
Step 1: Safety Preparation: Before starting the maintenance process, ensure the hammer mill is fully powered off.Total isolation of the device is highly recommended. It is vital to make sure the lockout-tagout procedure is in place to prevent accidental startup.It is essential to let the rotor stop completely before opening the access panels.
Step 2: Access & Inspection:Open the grinding chamber carefully and remove any accumulated material.Thoroughly inspect for accumulated material under the hammers and near the aperture. Such material accumulation indicates the wear pattern of key components and helps identify potential issues.
Step 3: Remove Worn Components: For hammers, it is essential to document their arrangement in your hammer mill. The original hammer arrangement must not be altered, as it must match the specified mounting pattern exactly to ensure rotor balance.The hammers contain spacer blocks, so they must be removed carefully. To remove the screen, it is essential to take out the retaining pins first, then extract the screen from the chamber.
Step 4: Install New Screens and Hammers: After removing the old screen, remember to clean the area. Proper installation of screens and hammers is essential, and this requires using the correct replacement parts.Maintaining the correct staggered mounting pattern and ensuring the cutting edges face the proper direction of rotation will optimize the performance of the newly installed screens and hammers.Install the hammers using the appropriate washers and screws, and secure the screens with the retaining rings.
Step 5: Final Verification: Verify that the rotor rotates smoothly without obstruction before closing the chamber.Ensure all tools are removed from the grinding chamber, reinstall the access doors, and then conduct an empty-run test.
Proper Replacement Matters: Correct installation ensures consistent particle size, optimal grinding efficiency, low energy consumption, extended equipment service life, and prevents unbalanced operation.
