更換易損件檢查指南

Machines that reduce the size of a material also erode the grinding elements. In general, the more abrasive the material you grind, the more and the more quickly the hammers and other parts wear. To ensure efficient operation and longevity of your Hammer mill, it’s crucial to regularly inspect and maintain its wear parts. These components include hammers, rods, 螢幕, 軸承, and wear plates. 在本指南中, we will walk you through the steps of inspecting wear parts on a hammer mill to keep it running smoothly and avoid costly downtime.

Tools and materials you’ll need

Before you begin inspecting wear parts on your hammermill, gather the following tools and materials:

• Safety glasses
• Ear protection
• Gloves
• Wrenches and socket set
• Screwdrivers
• Hammer
• 所需的任何替換零件

步驟 1: 錘子和錘棒的目視檢查

The hammers (51) are critical components of a hammermill, 其磨損會大幅影響性能. 每個錘子有四個撞擊邊緣. 當每個邊緣變得磨損時, rotate the hammer to use a new edge. 不要讓錘子磨損過多或使相對的打擊邊緣無法使用. 檢查錘子是否有磨損跡象. 常見的磨損指標包括:

• 邊緣圓滑
  • 當前緣變圓時旋轉錘子.
  • 當所有切削刃都是圓形的時, 更換錘子.
• 邊緣鈍化或破損
• 裂縫或斷裂

如果注意到以下問題，請旋轉錘子:

• 研磨效率下降，表現為研磨相同體積的物料需要更多時間, 溫度升高, 或電力使用增加.
• 檢查顯示錘子邊緣已圓滑.

Follow these steps to inspect the hammers (51) and hammer rods (52):

1. 打開磨機護罩 (43). 
2. Slide the hammer rods (52) of the row through the end of the rotor discs (49). 一次僅操作一列錘子.
3. 將該列的每個錘子以相同方式旋轉，以檢查打擊邊緣.
   1. 如果邊緣磨損, plan to rotate all hammers in the row to a new edge.
   2. When all 4 edges are worn, plan to replace all hammers in the row and the hammer rod.
4. Inspect the hammer rods for wear, indicated by grooving on the rod.
   1. Plan to replace the hammer rod if grooving is present.
5. Go to the next row. Do not interchange hammers from one row to another.
6. Check for imbalance: Ensure the hammers are evenly distributed across the rotor (48). Imbalanced hammers can lead to vibrations and reduced efficiency.
7. Replace worn hammers: If hammers show excessive wear or damage, replace them with new ones according to your mill manual.

步驟 2: Examine Screens

Your mill has either a perforated metal screen or grate on the front and rear of the mill. The screens (50) in your hammermill play a crucial role in determining particle size. Inspect them for wear and damage:

1. Remove screens (50): Use appropriate tools to remove the screens from the hammermill.
2. Check for wear: Look for signs of wear, such as holes, tears, or excessive clogging. Screens with worn-out openings can lead to inconsistent particle size.
3. Clean screens: If screens are clogged with material buildup, clean them thoroughly. A clean screen ensures better efficiency.
4. Replace damaged screens: If screens are damaged or worn beyond their usable life, replace them with new ones following the mill manual.

步驟 3: Inspecting Wear Plates

Wear plates protect the mill housing. There are two on the hood (45) of the mill and one at the back of the rotor (x). When a plate becomes worn, the housing is exposed to the material. Inspect the plate regularly for signs of wear or thinning.

1. 更換磨損板，當他們表現出的細化. Earliest signs of thinning are seen around the bolts. If you find excessive wear, replace with a new plate using new bolts.

步驟 4: Inspect Bearings

Properly functioning bearings (49) are essential for the hammermill’s smooth operation:

• Inspect bearings: Check for signs of wear, overheating, or vibration in the bearings. Replace any damaged or worn bearings promptly.

步驟 5: Lubricate Moving Parts

Proper lubrication of bearings (49) and moving parts is vital for reducing wear and extending the lifespan of your hammermill. Refer to your manual’s guidelines for the recommended lubrication schedule and type of lubricants to use. Properly lubricating is important for reducing friction and wear on moving parts:

• Apply lubricant: Lubricate all moving parts as instructed in the manual. Pay special attention to the rotor and bearings.

步驟 6: Final Checks

Before putting your hammermill back into operation, perform these final checks:

• Reassemble: Reassemble all components, ensuring that you’ve properly replaced any worn or damaged parts.
• Tighten all fasteners: Make sure all bolts, nuts, and fasteners are tightened to the recommended torque values.
• Test run: Start the hammermill and run it briefly to ensure it’s functioning correctly. Listen for unusual noises or vibrations.
• Record the inspection: Document the date of the inspection, the parts checked, and any maintenance or replacement actions taken.

步驟 7: Keep A Regular Maintenance Schedule

To keep your hammermill in optimal condition, follow a regular inspection and maintenance schedule for your hammermill. This schedule should include routine inspections, lubrication, and proactive replacement of wear parts before they cause significant issues.

It is also important to maintain detailed records of your inspections, including the date, findings, and any maintenance or replacement actions taken. This documentation can help you track the condition of your hammermill over time and plan for future maintenance.

By following these steps and maintaining a proactive approach to wear part inspections and maintenance, you can ensure the continued efficiency and safety of your hammermill while minimizing downtime and costly repairs. Always consult your hammermill’s manual for specific guidelines and recommendations related to your particular machine.
