Vibrating Feeder

Heavy-Duty Vibrating Feeder for Crushing Circuits

The Vibrating Feeder is an essential auxiliary machine placed at the very beginning of a mineral processing or aggregate crushing circuit. Its primary function is to receive massive loads of raw, coarse rock from excavators or dump trucks and feed them evenly and continuously into the primary coarse crusher (such as a Jaw Crusher).

By acting as a buffer and a regulator, this Rock Feeder Machine prevents sudden surges of material from choking the crusher, while also ensuring the crusher is never "starved" of material. This constant, optimized feed rate is the secret to maximizing the overall throughput and lifespan of your entire crushing plant.

Widely utilized in hard rock mining, artificial sand making, building materials, and the chemical industry, our Mining Vibrating Feeder is built with a heavy-duty steel trough designed to withstand severe impact from large boulders.

Core Advantages of Our Vibratory Feeder

• Stable & Continuous Operation: Utilizes dual eccentric vibration motors (or an eccentric shaft exciter) to produce a powerful, linear vibrating force that moves heavy, wet, or sticky materials smoothly without stalling.
• Flexible Flow Adjustment: Equipped with a Variable Frequency Drive (VFD) motor. Operators can instantly increase or decrease the feed rate by adjusting the frequency, allowing for real-time synchronization with the crusher's capacity.
• Impact-Resistant Design: The thick steel feeding trough is heavily reinforced with structural ribs to absorb the shock of massive boulders being dropped directly from heavy earth-moving equipment.
• Low Maintenance: Features a remarkably simple structure with no complex moving parts inside the material flow, ensuring quick, easy, and highly economical maintenance.

How It Protects Your Crushing Plant

Without a feeder, dumping rocks directly into a jaw crusher causes "choke feeding" (the motor stalls under the sudden weight) or "starve feeding" (the crusher runs empty, causing uneven wear on the plates). The vibrating feeder eliminates both issues.

1. Buffer Zone: The raw ore is dumped into a large hopper sitting directly above the feeder. The feeder absorbs the initial impact of the drop.
2. Linear Vibration: The vibration mechanism throws the rock forward and slightly upward in a continuous hopping motion along the steel trough.
3. Metered Discharge: The rocks cascade off the end of the trough into the crusher at a controlled, steady pace, allowing the crusher to operate at peak electrical and mechanical efficiency.
