A Motorised Vibratory Grizzly Feeder is a heavy-duty material handling machine equipped with vibratory motors and grizzly bars that simultaneously feed and separate oversized materials from finer particles before they enter the primary crusher.

The grizzly section allows smaller materials to pass through the openings while larger rocks continue toward the crusher, improving crusher performance, reducing wear, increasing throughput, and minimizing power consumption.

These feeders are widely used in mining, quarrying, aggregate processing, cement plants, coal handling, recycling, and mineral processing industries.

Magbro Tech Industries manufactures robust Motorised Vibratory Grizzly Feeders engineered to handle large rocks, aggregates, ores, coal, limestone, and other heavy bulk materials under the toughest operating conditions.

Our feeders feature a fabricated heavy-duty structure, high-quality vibratory motors, wear-resistant grizzly bars, replaceable liners, and spring-mounted assemblies for reliable and vibration-free performance. Each feeder is customized according to plant capacity, material characteristics, feed size, and installation requirements.

Working Principle

The feeder is mounted on heavy-duty springs and driven by two synchronized vibratory motors.

• Raw material is discharged into the feeder hopper.
• Twin vibratory motors generate linear vibrations.
• Material moves uniformly across the feeder tray.
• Fine material passes through the grizzly bars.
• Oversized material continues toward the primary crusher.
• The crusher receives only the required feed size, improving crushing efficiency.

This dual-function operation ensures both controlled feeding and effective scalping in a single machine.
