The fluorite color sorter is core equipment in fluorite beneficiation. Its operational stability directly affects sorting efficiency, product purity and enterprise economic benefits. Dust and humidity fluctuations are common in fluorite processing. Targeted daily maintenance can effectively reduce faults and extend service life. The key maintenance points are detailed as follows:

1. Daily Cleaning: Remove Dust to Protect Optical System

Dust is the main hidden hazard of fluorite color sorters. Complete cleaning shall be conducted daily after shutdown:

Contact Parts Cleaning: Blow the feeding hopper, vibrating feeder, chutes and discharge trough with compressed air, or clean gaps with a soft brush to prevent material blockage and component wear caused by dust caking.

Optical Glass Maintenance: The lens protective glass and background plate glass in the sorting chamber are critical for visual identification. Wipe gently with lint-free cloth dipped in anhydrous alcohol; never scrape with hard tools to avoid scratches and ensure full transparency.

Internal Dust Removal: Regularly clean the internal dust filter to keep ventilation and heat dissipation unobstructed, preventing dust accumulation from shortening the service life of electronic components.

2. Maintenance of Key Components: Prevent Wear and Blockage

Vibration System

Check if fixing bolts of the vibration motor are loose, and whether springs are deformed, broken or aging; replace abnormal parts in a timely manner. Observe the amplitude uniformity of the vibrating feeder; adjust eccentric blocks or spring positions if material deviation occurs to ensure even material distribution.

Optical System

Regularly check the fixation of cameras and photoelectric sensors to avoid displacement. Monitor light source brightness; replace light source modules in case of attenuation or flicker to guarantee sorting accuracy.

Air Jet System

Remove and back-blow nozzles with compressed air weekly to clear fluorite powder blockage. Check the response speed of solenoid valves; replace sealing rings or repair the valve body if jamming or air leakage occurs.

3. Lubrication Maintenance: Reduce Wear of Moving Parts

Lubrication is essential for extending equipment life:

Inject lithium-based grease into bearings of vibration motors and conveyor rollers monthly, filling 1/2–2/3 of bearing clearance; overfilling easily adsorbs dust.

Regularly adjust conveyor belt tension: too loose causes slipping, too tight accelerates wear; calibrate to proper tension via tension pulleys.

4. Electrical System Inspection: Prevent Short Circuit & Stabilize Circuit

Daily Check: Confirm no damage to power cables and reliable grounding before startup.

Regular Maintenance: Open the control cabinet weekly to blow off internal dust with compressed air; check for loose or oxidized terminals. Monitor temperature of inverters, PLC and other components; clean radiator fan filters or replace fans in case of overheating.

Static Protection: Ensure reliable equipment grounding to avoid static interference with optical systems and electronic parts.

5. Software & Parameter Calibration: Guarantee Sorting Precision

Parameter Calibration: Calibrate color level, sensitivity, jet time and other parameters weekly with standard fluorite samples of different purity and color to maintain sorting accuracy.

Data Backup: Back up color sorter software data regularly to prevent parameter loss.

Troubleshooting: Contact manufacturer technicians promptly for software errors; do not modify programs without authorization.

6. Environment Management: Optimize Operating Conditions

Fluorite color sorters require dry and well-ventilated operating conditions:

Equip the workshop with dust removal equipment to lower dust concentration.

Control ambient humidity at 40%–60% to avoid electrical rust and short circuit caused by dampness.

Implement cooling in summer to prevent overheating and antifreeze measures in winter to avoid pipeline rupture.

7. Regular Professional Overhaul: Prevent Potential Faults

Arrange professional manufacturer technicians for comprehensive inspection quarterly or semi-annually:

Test motor insulation performance and replace worn parts such as nozzles, conveyor belts and springs.

Calibrate the sorting system accuracy to keep equipment in optimal condition.

Establish maintenance files to record fault handling and spare parts replacement for subsequent maintenance reference.
