Delivery Standard
The focus of the inspection is different for different devices. Select the type of equipment to see the items and qualified lines that our engineers must check before the equipment is released for export.
Key points of crushing equipment inspection
Crushing equipment is most afraid of dark injuries: cavity cracks, spindle wear, lining plate filling, test and write the report one by one.
- Cavities and racks: Flaw detection No cracks, no repair welding
- Lining and hammer: Measure the remaining thickness and take a photo to archive
- Spindle and bearing: Bounce amount, gap measurement, no-load test machine listening
- Hydraulic/Lubrication System: Stable pressure, no leakage, oil sampling
- Motor & Electrical Control: Insulation resistance measurement, full-load current recording
- Hourly charts and archives: Check the repair records and the replacement history of the wearing parts
Qualified Lines
- Remaining life of the lining plate: ≥ 50% (Below this offline rating)
- Spindle runout: ≤ 0.05 mm (Excessive standards will not be released from the factory)
- No-load test machine: ≥ 30 minutes (abnormal sound will be removed from the shelf for re-inspection)
Key points of machine inspection for sand making equipment
The sand making machine looks at the impeller and lubrication: the wear of the impeller directly determines the sand grading, and the state of the thin oil station determines the life of the whole machine.
- Impeller & Runner Plate: Actual wear measurement, complete inspection of the throwing head
- Primary shaft assembly: Measurement of bearing temperature rise and vibration value
- Thin oil lubrication station: Oil pressure, oil temperature, filter element status
- Trial production of finished sand: Strip testing machine, sampling screening and grading
- Motor and Variable Frequency: Stable current curve with no abnormalities
- Hourly charts and archives: Check maintenance and replacement records
Qualified Lines
- Impeller Remaining Life: ≥ 60% (according to the measured discount)
- Vibration value: ≤ 4.5 mm/s (Exceeding the standard will not be released from the factory)
- Strip testing machine: ≥ 2 hours (sampling 3 screenings)
Key points of machine inspection of grinding equipment
Mill seals and grinding rolls: Sealing failure can cause powder leakage and contamination. The grinding roll assembly is the most expensive part of the whole machine and must be disassembled and inspected.
- Grinding Roller Assembly: Disassembly and inspection of bearings and seals, measurement of roller surface wear
- Analyzer: Impeller deformation and clearance check
- Plumbing & Dust Removal: Check for air leakage points, filter bag status
- Finished product fineness trial production: Strip test grinding, sampling and measuring fineness
- Speed reducer: Tooth Surface and Oil Inspection
- Hourly charts and archives: Verify overhaul records
Qualified Lines
- Remaining life of the grinding roller: ≥ 55% (according to the measured discount)
- Finish Fineness Deviation: ≤ 5% (Overshoot will not be released from the factory)
- Strip test grinding: ≥ 2 hours (sampling 3 tests)
Key points of machine inspection of mineral processing equipment
The mineral processing equipment looks at the cylinder and magnetic system: the ball mill checks the liner plate and the large gear. The magnetic separator must measure the surface field strength of the cylinder, and the demagnetization is a significant devaluation.
- Cylinders and liners: Measured thickness, no cracks, no leakage
- Big Gear/Magnetic: Tooth surface pitting corrosion inspection; field strength measured point by point
- Main bearing: Temperature rise and oil film status
- <span> DRIVE TRAIN </span>: Coupling and reducer abnormal noise check
- No-load + belt testing machine: Current and output double recording
- Hourly charts and archives: Check the liner replacement cycle
Qualified Lines
- Remaining life of the lining plate: ≥ 50% (Below this offline rating)
- Strong attenuation of cylinder surface field: ≤ 10% (Excessive standards will not be released from the factory)
- Main bearing temperature rise: ≤ 35 ℃ (re-check if exceeded)
