Vibrating Feeder
Mitool Equipments Pvt. Ltd. designs, manufactures and exports heavy-duty vibrating feeders from its Ambernath MIDC facility near Mumbai. Our vibrating feeders move bulk materials — from limestone and coal to plastic pellets, sand, sponge iron and food granules — with controlled flow rates, low energy consumption, and minimal mechanical wear. Two distinct drive systems are offered: electromagnetic and electromechanical, each tuned for a different class of duty.
Operating across steel plants, foundries, cement units, power stations, fertiliser plants and FMCG production lines, Mitool vibratory feeders are engineered with the kind of stepless flow control and 24×7 duty cycle that high-throughput industries demand. Every unit can be customised in tray width, length, and capacity to match the specific hopper, conveyor, or downstream equipment in your plant layout.
Working principle of a vibrating feeder
A vibrating feeder transports material by inducing controlled vibrations in a steel tray. Material on the tray is repeatedly thrown forward in tiny micro-hops, creating a smooth, even discharge. By varying either the voltage (in electromagnetic units) or the eccentric weight setting (in electromechanical units), the operator can precisely control how fast material moves — anywhere from a trickle to several hundred tonnes per hour.
Electromagnetic vibrating feeder
Mitool's electromagnetic vibrating feeders use an AC-powered electromagnet to generate high-frequency, low-amplitude vibrations. They have no rotating parts, no bearings to lubricate, and respond instantly to control signals, making them ideal for precision dosing in pharmaceutical, food, chemical and grinding applications.
- Stepless flow control: 0–100% feed rate adjustable through a thyristor-based controller.
- No moving parts: No bearings, no gears — almost zero maintenance.
- Low power consumption: Typically 40–60% lower than equivalent electromechanical units.
- Instant start/stop: Stops within one vibration cycle when power cuts — critical for batch dosing.
- Dust-tight & moisture-proof drive: Fully sealed electromagnet enclosure.
Electromagnetic vibrating feeder
Mitool's electromechanical (unbalance-motor driven) feeders are the workhorses of heavy industry. Two identical vibratory motors are mounted in parallel, rotating in opposite directions. Their counter-rotating eccentric weights cancel out horizontal forces and leave only a strong linear vibration that drives bulk material forward. Used wherever a constant, high-capacity feed is needed — typical applications include feeding crushers, kilns, mills, and conveyors in steel, cement and mining plants.
- Heavy-duty construction: channel-section trays with replaceable wear liners
- High capacity: up to several hundred tonnes per hour in standard sizes; custom builds to thousands of TPH
- Adjustable amplitude: Typically 40–60% lower than equivalent electromechanical units.
- Base-mounted or suspension-mounted: configurable for floor installation, structural-steel suspension, or hybrid
- Tubular variant available: round-section or square-section tubular feeders from 160 mm to 500 mm diameter, lengths 1 m to 5 m, for dust-sensitive transport

Frequently Asked Questions
A. Electromagnetic feeders use an AC electromagnet (no moving parts) for high-frequency, low-amplitude vibration — ideal for precise dosing of fine materials. Electromechanical feeders use two unbalance motors generating low-frequency, high-amplitude vibration — ideal for heavy-duty, high-capacity bulk material handling. Mitool manufactures both.
A. Standard Mitool vibrating feeders cover 5 TPH to 1500 TPH. Larger custom builds for specific applications such as iron ore primary feeding can be engineered on request.
A. Yes. We engineer feeders with Hardox or stainless-steel liners for abrasive materials, with anti-stick PU liners for sticky materials, and with closed-tubular construction for wet or fugitive-dust materials. Share your material data sheet at the enquiry stage.
A. Yes — Mitool's service team supports installation, alignment, electrical connection, and commissioning across India. For export orders, video-supported remote commissioning is provided.
A. Standard sizes ship in 4–6 weeks from order confirmation. Custom and large-capacity units typically take 8–10 weeks. Stainless-steel and special-material builds may take longer depending on raw material lead time.
