Maintaining your vibrating feeder is crucial for ensuring its reliable and efficient operation, prolonging its lifespan, and preventing costly breakdowns. Here's a comprehensive guide to vibrating feeder maintenance:
I. Regular Inspection & Preventative Maintenance:
Daily/Shiftly Inspection: (Depending on usage intensity)
Visual Inspection: Look for:
Loose bolts and fasteners (especially on the vibrator drive).
Cracks or damage to the trough, springs, or frame.
Excessive wear on the trough liner (if applicable).
Material buildup or spillage.
Unusual noises or vibrations.
Check the power cord and connections for damage or looseness.
Cleanliness: Remove any accumulated material buildup around the feeder, especially around the vibrator drive and springs.
Operational Check: Ensure the feeder starts and stops smoothly and the feed rate is consistent.
Weekly/Monthly Inspection:
Vibrator Drive Inspection:
Electromagnetic Vibrators:
Check the air gap between the armature and the electromagnet. Refer to the manufacturer's specifications for the correct gap.
Inspect the coil for overheating or damage.
Check the rectifier and control circuitry for proper operation.
Mechanical Vibrators:
Check the bearings for wear and proper lubrication. Regrease according to manufacturer's recommendations.
Inspect the eccentric weights for proper balance and secure mounting.
Check the drive motor for proper operation and lubrication.
Spring Inspection:
Examine the springs for cracks, breaks, or distortion. Replace any damaged springs.
Check spring tension and adjust if necessary.
Trough Inspection:
Inspect the trough liner for wear and damage. Replace the liner as needed.
Check the trough mounting for proper alignment and support.
Fastener Tightening: Re-torque all bolts and fasteners to the specified torque values.
Vibration Isolation: Check the condition of rubber mounts or springs used for vibration isolation to prevent damage to the feeder supports.
Annual/Overhaul Inspection:
Complete Disassembly and Cleaning: Thoroughly clean all parts of the feeder.
Detailed Inspection: Inspect all components for wear, damage, and corrosion.
Bearing Replacement: Replace bearings in the vibrator drive, even if they appear to be in good condition.
Spring Replacement: Consider replacing springs to maintain consistent performance.
Motor Check: Have the motor checked by a qualified electrician.
Control System Calibration: Recalibrate the control system for optimal performance.
Repainting: Repaint the feeder to prevent corrosion.
II. Lubrication:
Bearing Lubrication: Use the correct type of grease specified by the manufacturer. Over-greasing can be as detrimental as under-greasing. Follow the manufacturer's recommended lubrication schedule.
Motor Lubrication: Lubricate the motor bearings according to the motor manufacturer's instructions.
Other Lubrication Points: Lubricate any other moving parts as recommended by the manufacturer.
III. Troubleshooting Common Problems:
Reduced Feed Rate:
Possible Causes: Low voltage, incorrect frequency setting, excessive material buildup, worn springs, loose fasteners, worn or damaged vibrator drive, incorrect amplitude setting.
Troubleshooting: Check voltage and frequency, clean the feeder, inspect springs and fasteners, repair or replace vibrator drive, adjust amplitude.
Excessive Noise or Vibration:
Possible Causes: Loose fasteners, worn bearings, unbalanced vibrator drive, damaged springs, material buildup, improper mounting.
Troubleshooting: Tighten fasteners, replace bearings, balance the vibrator drive, replace springs, clean the feeder, inspect mounting.
Feeder Stops Working:
Possible Causes: Power failure, tripped circuit breaker, overload, faulty control system, damaged vibrator drive.
Troubleshooting: Check power supply, reset circuit breaker, reduce load, repair or replace control system, repair or replace vibrator drive.
Uneven Material Distribution:
Possible Causes: Uneven trough wear, improper leveling, incorrect amplitude setting, material segregation.
Troubleshooting: Replace trough liner, level the feeder, adjust amplitude, adjust the feeder incline.
Material Bridging or Arching:
Possible Causes: Moisture content too high, improper material size distribution, insufficient vibration amplitude.
Troubleshooting: Reduce moisture content, adjust material size distribution, increase vibration amplitude.
IV. Safety Precautions:
Lockout/Tagout: Always lock out and tag out the feeder's power supply before performing any maintenance.
Personal Protective Equipment (PPE): Wear appropriate PPE, such as safety glasses, gloves, and hearing protection.
Qualified Personnel: Only qualified personnel should perform complex repairs or maintenance on the vibrator drive or control system.
Manufacturer's Instructions: Always follow the manufacturer's instructions for maintenance and repair.
Clean Work Area: Maintain a clean and organized work area.
V. Documentation:
Maintenance Log: Keep a detailed maintenance log of all inspections, lubrication, repairs, and replacements. This will help you track the feeder's performance and identify potential problems early on.
Parts Inventory: Maintain an inventory of critical spare parts, such as bearings, springs, and liners.
Manufacturer's Manuals: Keep the manufacturer's manuals readily available for reference.

Vibrating feeder product introduction
This series of products in the production process, can be block, granular from the main material warehouse uniform, timed, continuous to the receiving device, in the sand and gravel production line for crushing machinery continuous and uniform feeding, and coarse screening of materials, widely used in metallurgy, coal mining, mineral processing, building materials, chemical industry, abrasives and other industries in the crushing, screening and joint equipment.
Working Principle
According to the vibration synchronization theory of plane sound mass, when the two vibration motors operate in the opposite direction at the same angle, the inertia force in the vertical direction of the vibration motor rotating center line is in the same direction, and iterated with each other, and under the action of the inertia force, the feeding trough will do intermittent vibration along the direction of the combined force, so as to achieve the purpose of conveying the materials.
