Operation Demonstration

Working Principle

The Linear Vibrating Feeder employs dual eccentric shaft self-synchronization technology. Two eccentric shafts are mechanically synchronized through gears, rotating in opposite directions at equal speeds to generate directional excitation force, causing the trough to perform linear reciprocating vibration in a fixed direction.

Operating Process:

  • Power Transmission → Motor drives dual eccentric shafts via V-belt
  • Excitation Generation → Eccentric masses create centrifugal force, forming resultant linear excitation force
  • Trough Vibration → Trough performs linear projectile motion along inclined direction
  • Material Conveying → Materials execute parabolic jumps on trough surface, achieving rapid and uniform feeding
  • Pre-screening (Optional) → Fine particles are pre-removed through grizzly bar gaps
Technical Characteristics:

Dual-shaft forced synchronization ensures precise linear vibration trajectory without material segregation, suitable for large particle size and high-capacity operations.

FAQ

Q1: What is the difference between Linear Vibrating Feeder and Dual Motor Vibrating Feeder?
A: The Linear Vibrating Feeder (this equipment) employs dual eccentric shafts with gear forced synchronization, featuring large excitation force, large feed size (≤750mm), and high capacity (up to 360t/h), suitable for heavy-duty mining conditions. The Dual Motor Feeder (ZD series) employs dual motor self-synchronization, with simple structure, convenient maintenance, and low energy consumption, suitable for small and medium-scale production lines.
Q2: What are the advantages of dual eccentric shaft over single eccentric shaft feeders?
A: Dual-shaft forced synchronization produces pure linear vibration with concentrated material conveying direction and no segregation; single-shaft produces elliptical vibration with material tendency to deviate. Dual-shaft is suitable for high-capacity, large-particle conditions; single-shaft is suitable for precision feeding.
Q3: Does the gear synchronization system require special maintenance?
A: The gearbox uses N220 medium-duty gear oil; check oil level every 500 hours, replace gear oil every 6 months; check gear meshing clearance every 2000 hours. Normal clearance 0.2-0.3mm; adjustment or replacement required if exceeding 0.5mm.
Q4: How to handle large material blockage?
A: ① Install grizzly at bin outlet to control maximum particle size within equipment limits; ② Adjust trough inclination to 12-15° to enhance material flowability; ③ Configure variable frequency speed control to instantaneously increase vibration frequency when blockage occurs.
Q5: How to select pre-screening grizzly bar spacing?
A: Generally select 0.8-1.0 times the downstream crusher discharge opening size. Example: jaw crusher discharge opening 100mm, grizzly spacing selectable 80-100mm, ensuring screened material can directly enter next stage without secondary crushing.
