1、 Daily cleaning and protection

1. Screen cleaning
   • After each useUse a brush or long handled scraper to clean the sieve, remove particles that block the sieve holes, and avoid material residue that may cause deformation or corrosion of the sieve holes.
   • deep cleaningOpen the device casing every week, clean the internal vibrating components, transmission devices, and wind selection platform (such as fish scale holes) to prevent dust and oil accumulation from affecting heat dissipation and transmission efficiency.
   • Do not hit hard objectsWhen cleaning the sieve, it is strictly prohibited to use hard objects to strike, in order to prevent uneven material flow caused by uneven surface of the sieve.
2. Equipment surface maintenance
   • Regularly clean the surface of the equipment, promptly remove rust and apply paint to areas where paint has peeled off, and apply industrial Vaseline to exposed processing surfaces for rust prevention.

2、 Key component inspection and replacement

1. Screen inspection
   • frequencyCheck the material characteristics (such as humidity, particle shape) every 1-3 months, and replace immediately if any damage, deformation, or enlarged sieve holes are found.
   • Key points for replacementAfter the installation of the new screen mesh, it needs to be re tensioned every 4-8 hours until it is fixed; When overlapping the screen surface, the front section should be pressed on top of the rear section to ensure flatness.
2. Spring inspection
   • frequencyCheck at least once a year, with a focus on observing whether the spring is fatigued, deformed, or broken.
   • Replace standardIf the elasticity of the spring decreases and the screening effect decreases or the equipment vibrates abnormally, it is necessary to replace the spring with the same specification.
3. Vibration motor and transmission components
   • Motor inspectionRegularly measure insulation resistance to ensure good insulation performance; Check if the cooling fan is blocked or damaged to prevent the motor from overheating.
   • Transmission componentsCheck the tightening of bolts such as exciters, bearings, and chains every week, and tighten them promptly if any looseness is found; When the V-belt is worn or insufficiently tensioned, it needs to be adjusted or replaced.

3、 Lubrication and maintenance

1. lubrication interval
   • Vibration motor bearingsAdd lithium based grease (ZL-3) every two weeks, check the bearings after running for 1500 hours, and replace them immediately if damaged.
   • Sliding or vibrating partsRegularly apply lubricating oil to reduce friction and wear.
2. Lubrication precautions
   • Use original factory specified lubricants to avoid mixing and causing component damage; Clean up oil stains and impurities before lubrication to prevent contamination of the lubrication system.

4、 Exception handling and troubleshooting

1. abnormal vibration
   • Possible reasonsVibration motor malfunction, spring damage, and unbalanced screen body.
   • treatment method：
     • Check the power supply and insulation performance of the motor, confirm that there is no damage, and then test the operation of the motor.
     • Check if the spring elasticity is consistent, and replace it with a spring of the same specification if it is damaged.
     • Clean up the material accumulation of the sieve body, tighten loose parts, and ensure the balance of the sieve body.
2. Decreased screening efficiency
   • Possible reasonsScreen clogging, damage, or changes in material properties (such as increased humidity or changes in particle shape).
   • treatment method：
     • Clean or replace the screen mesh, adjust the screening process parameters (such as vibration frequency and amplitude).
     • If the humidity of the material is high, the water spray volume can be increased or the inclination angle of the screen surface can be adjusted to prevent material adhesion.
3. Electrical fault
   • Possible reasonsFuses, relays, contactors are damaged or the circuit is short circuited or broken.
   • treatment methodCheck the electrical control system components and replace damaged parts; Repair or replace damaged circuits to ensure good grounding.

5、 Shutdown management and long-term storage

1. Shutdown operation
   • sequenceStop feeding first, stop the screening mechanism after the materials have left, and finally stop the fan.
   • clean upAfter stopping the machine, clean the accumulated grains and impurities in the sieve body, and check whether the sieve grid is firmly installed.
2. long-term storage
   • rust prevention treatmentApply rust proof oil to metal parts and cover them with dust covers to prevent dust from entering.
   • Fixed equipmentDuring flood season or shutdown, tie the equipment in a secure position to prevent it from being washed away or overturned by water flow.
   • Record and archiveEstablish maintenance files to record maintenance time, replacement parts, and equipment status, providing reference for subsequent maintenance.
