Vibro Feeder - FJ Series
The Nesans FJ Series Vibratory Pan Feeders are designed for reliable and controlled feeding of bulk materials in a wide range of crushing, screening, and material handling applications. Built with heavy-duty components and a high-torque vibratory drive, the FJ Series ensures consistent, linear material flow—even under tough operating conditions and with variable load sizes.
Material is gently introduced into the pan, where twin vibratory motors generate synchronized linear motion. This motion moves the material forward while promoting even distribution across the width of the pan. The design is ideal for regulating feed into crushers, screens, or belts—especially where volume consistency and flow control are critical for plant efficiency and downstream equipment protection.
With its robust construction, spring-mounted base, and abrasion-resistant liners, the FJ Series is engineered to handle everything from fines to large aggregates. Easy to install and maintain, it’s the go-to solution for operators who demand long-term reliability, minimal downtime, and smooth material handling across various industrial applications.

How It Works
The Nesans FJ Series Vibratory Pan Feeders operate on the principle of linear vibratory motion generated by twin unbalanced motors mounted on either side of the feeder. These motors rotate in opposite directions, producing a synchronized linear force that moves material forward in a controlled, consistent flow. The entire feeder assembly is mounted on heavy-duty coil springs, allowing it to vibrate freely while isolating the motion from the base structure.
Material enters the feeder through a hopper or chute and lands in the abrasion-resistant feed pan. The linear vibration gently pushes the material forward, ensuring uniform distribution and eliminating sudden surges that could damage downstream equipment. The feeder’s stroke and vibration frequency are tuned to the specific application, ensuring optimal flow for both fine and coarse materials.
This simple yet effective working principle ensures low power consumption, minimal mechanical wear, and excellent feed control, making the FJ Series a reliable choice for regulated bulk material handling in continuous processing environments.

It operates on the principle of linear vibratory motion generated by twin unbalanced motors mounted on either side of the feeder. These motors rotate in opposite directions, creating synchronized linear force that moves material forward in a smooth, controlled flow.
- Feeding primary crushers with controlled flow.
- Transferring material from hoppers, bins, or silos.
- Feeding screening machines evenly.
- Handling sticky, fine, or abrasive bulk solids.
It is suitable for sand, aggregates, crushed rock, coal, ores, minerals, and industrial bulk solids, whether wet or dry.Everything from fine sand and powders to large, heavy aggregates. The abrasion-resistant feed pan ensures durability even with abrasive rock.
- Wear liners in the feed zone.
- Scalping bars (if fitted).
- Bearings in vibro motors/exciter.
Yes. It performs reliably even under fluctuating feed loads, ensuring steady downstream operation.
The feeder is mounted on coil springs or rubber mounts that isolate vibrations, protecting the supporting structure from dynamic forces.
By delivering material at a steady, controlled rate, it prevents surges and maintains consistent crusher performance.
Signs include irregular material flow, excess noise, or reduced vibration amplitude. Usually caused by loose springs, misaligned motors, or worn bearings.
The linear vibration spreads material across the full width of the pan, ensuring uniform feeding into downstream machines.
By delivering material in a smooth, evenly distributed flow, it prevents sudden surges that can choke crushers, overload screens, or damage belts.
- Daily: Monitor for noise and overheating.
- Weekly: Check mounting bolts and alignment.
- Monthly: Grease bearings and inspect electrical connections.
Yes. The high-torque twin vibro motors allow the feeder to start and operate even under a full bin or hopper load, making it reliable for continuous use.
- Pan Feeder (FJ): Focuses only on controlled feeding and flow regulation.
- Grizzly Feeder: Includes scalping bars to remove fines before material enters the crusher.
- Vibro Feeder: Excellent for scalping, coarse feed, and impact loads; low maintenance.
- Belt Feeder: Better for fine, sticky, or precise feed regulation.
