Linear Vibrating Feeder & Dual Eccentric Shaft Feeder
What is a Linear Vibrating Feeder?
The linear vibrating feeder (widely designated as a dual eccentric shaft feeder) independently developed by Hengtai is a high-efficiency continuous feeding equipment for integrated crushing and screening systems. Driven by a dual eccentric shaft vibrator with V-belt power transmission, it features linear projectile conveying characteristics and is widely applied in mining, building materials, chemical, and silicate industries. This equipment integrates feeding and pre-screening functions, effectively removing soil and impurities to enhance downstream equipment efficiency. Adaptable to materials of varying hardness, it has become a core feeding device in global production lines, providing reliable solutions for diverse industrial applications.

How the Linear Vibrating Feeder Operates
Understanding the continuous, high-efficiency mechanical conveying mechanism of our dual eccentric shaft feeder.
Power Transmission: The electric motor drives dual eccentric shafts via V-belt transmission through the heavy-duty drive system, delivering reliable mechanical power to the vibrator assembly.
Excitation Generation: Two eccentric shafts are mechanically synchronized through herringbone gears, rotating in opposite directions at equal speeds. Adjustable eccentric masses create centrifugal force, forming a resultant directional linear excitation force without slip or deviation.
Material Conveying & Pre-screening: The trough performs linear reciprocating vibration along an inclined direction; materials execute parabolic jumps on the trough surface, achieving rapid and uniform feeding. Optional grizzly bar pre-screening removes fines and soil, enhancing downstream crusher efficiency by over 30%.

Frequently Asked Questions (FAQ)
Quick professional engineering insights regarding dual eccentric shaft synchronization and equipment selection.
Q1: What is the difference between Linear Vibrating Feeder and Dual Motor Vibrating Feeder?
The Linear Vibrating Feeder 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?
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?
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.
