How to start a mobile crusher?

As core equipment in mining, quarrying and construction waste recycling, the correct startup operation of a mobile crusher is directly related to service life, production efficiency and personnel safety. Different from stationary production lines, a mobile crusher integrates feeding, crushing, screening and conveying, with a more systematic startup process. The following is a standardized startup guide for global users.

1. Comprehensive Inspection Before Startup

1.1 Power System Inspection

Mobile crushers are usually driven by a diesel engine. Before startup, confirm the following:

• Whether the diesel fuel level is sufficient
• Whether the engine oil level is within the normal range
• Whether the coolant level is normal
• Hydraulic oil level and pipelines for leakage
• Battery voltage is normal (no-load voltage ≥25V); recharge in advance if the machine has been idle for a long time

For the first startup after winter shutdown, it is recommended to replace the engine oil and carefully check aging and fastening of rubber hoses.

1.2 Working Device Inspection

• Check for material accumulation in the crushing chamber; mobile crushers must be started without load
• Ensure the conveyor belt has no deviation or damage, and joints are intact
• Check whether all connecting bolts are tightened
• Check bearing lubrication and add lubricant as needed
• Confirm electrical instruments are at zero and the emergency stop switch is intact

1.3 Safety Confirmation

• Ensure no personnel are around or inside the crushing chamber
• Check track conditions (crawler models) or tire lift and outrigger stability (wheel models)
• Confirm rotor locking devices are removed and protective covers are installed

2. Standard Startup Sequence

Mobile crushers follow the downstream-to-upstream principle: start discharge equipment first and feeding equipment last to ensure smooth material flow and avoid blockage.

Standard Startup Steps (diesel generator driven)

For remote-controlled crawler mobile crushing plants, after the electrical startup process:

• Use the remote control to increase engine speed to 1000–1100 rpm (max 1500 rpm)
• Operate travel and deployment gently and slowly

3. Inspection and Adjustment After Startup

3.1 No-load Operation Confirmation

After startup, run the machine without load for at least 15 minutes and check:

• Bearing temperatures are normal
• No abnormal noise or vibration
• No oil or liquid leakage
• Instruments show normal readings

3.2 Parameter Setting

Adjust according to production requirements:

• Set crusher discharge opening size
• Adjust gap between impact plate and crushing plate
• Set feeder speed

3.3 Start Production

Begin feeding only after no-load operation is normal. Start with small and uniform feeding, then gradually increase to rated capacity after stable operation.

4. Shutdown Procedure

Shutdown sequence is the reverse of startup, following the upstream-to-downstream principle:

1. Stop the feeder and stop feeding
2. Stop the main crusher after all materials in the chamber are crushed and discharged
3. Stop the vibrating screen
4. Stop the conveyor belt
5. Shut down the generator set

Special reminder: Do not shut down directly with materials inside the crushing chamber, as this may cause overload and jamming during the next startup.

5. Key Safety Operation Points

6. Summary

The core of correctly starting a mobile crusher can be summarized as Three Checks, One Sequence, Two Prohibitions:

• Three Checks: sufficient fuel and fluids, empty crushing chamber, no personnel in danger zones
• One Sequence: strictly follow downstream to upstream startup order
• Two Prohibitions: no startup with material inside; no shutdown with material inside

Shanghai Dongmeng crawler mobile crushing series adopts an intelligent control system with fully automatic startup guidance and self-diagnosis functions, greatly reducing operation difficulty.
