Three tips for jaw crusher maintenance! Extend the life of the jaw crusher by 5 years!

🔥**「Lazy Man’s Life-Saving Tips」A broken jaw can save you 5 years of repairs! Save the money for an iPhone every month! **🔥

💔The pain of the crusher boss:

👉"The jaw plate just replaced cracked after 3 months? Blood loss!"

👉"The bearing broke and stopped working for 3 days, the loss is enough to buy a Tesla!"

👉"Will the grease applied randomly accelerate wear? No one on the Internet tells the truth!"

Three tricks of the old mining driver㊙️ (with operation diagram + cost 0 yuan)

(The actual test extended the life by 5 years, my colleagues asked me to delete the post😂)

✅The first trick: Lubrication system "Golden Three Minutes"-the secret of living 2 more years

⏰Time: Before starting the machine in the morning shift every day (it is recommended to avoid high temperature periods in 2025)

🔧Operation:

1️⃣ Wipe the gun: Use diesel cotton cloth to clean the grease nozzle to prevent sand and dust from mixing in (⚠️ Mixed impurities = lubrication failure!)

2️⃣ Injection: Inject lithium grease with a high-pressure grease gun (use #3 in summer and #2 in winter), and stop immediately when you hear the "puff" sound!

3️⃣ Temperature measurement: Scan the bearing with an infrared thermometer, and stop the machine immediately if it is >70℃ to check the cause!

💰How much can you save: Correct lubrication = 3 times longer bearing life, saving 20,000+ yuan in replacement costs per year!

✅The second trick: Jaw plate "Great Shift" - Zero-cost resurrection

🔍Principle: Uneven wear of the upper and lower jaw plates? Turn them around and continue using them!

🛠Steps:

1️⃣ Disassembly: Loosen the wedge after shutdown and use a hydraulic jack to push out the jaw plate (⚠️Wear anti-cut gloves!)

2️⃣ Turn over: Rotate the lower wear area 180° and reinstall it, allowing the unworn surface to continue working

3️⃣ Measurement: Use a feeler gauge to check the jaw plate gap and control it at 2-5mm (small value for granite and large value for coal gangue)

💡Case: With this trick, an iron mine reduced the annual consumption of jaw plates from 12 pieces to 6 pieces!

✅The third move: Bolt "dynamic tightening spell" - anti-loosening black technology

⚡Pain point: Vibration causes bolt loosening → equipment displacement → whole machine scrapped!

🔨God operation:

1️⃣ Marking method: Draw a red alignment line on the bolt after tightening, and check whether the line is misaligned before the shift

2️⃣ Washer method: Add spring washer + rubber washer double-layer buffer (⚠️Ordinary flat washers are prohibited!)

3️⃣ Torque method: According to the torque value in the manual, tighten with a hydraulic wrench in 3 times (for example: M36 bolt ≈ 1800N·m)

🌰Data speaks: A sand and gravel plant insists on daily inspections, and there have been no bolt breakage accidents in 5 years!

❌The thicker the butter, the better? Wrong! It will block the heat dissipation holes!

❌Can the jaw plate still be used if it has cracks? Leakage! Be careful of splashing and injuring people!

❌Use ordinary engine oil instead of grease? Stop it! High temperature will cause coking!

🌟Summary: 3 maintenance tips = 5 minutes a day + save 100,000 yuan in maintenance fees per year! Equipment owners should save it quickly, and colleagues will be jealous when they see it!
