vibrating grizzly feeder for primary crushing operations

Vibrating Grizzly Feeder Overview

Vibrating grizzly feeder integrates feeding and coarse screening functions, utilizing its grizzly structure at the front end to reject soil and fines. Typically arranged at the front end of crushing production lines, it is particularly suitable for mobile crushing plants and primary feeding operations in small and medium-sized mines.

Main Features of Vibrating Grizzly Feeder

1. Integrated structure: Combines feeding and screening in one unit, reducing the burden on subsequent equipment.
2. Vibrating motor drive: Uses a high-efficiency, energy-saving vibrating motor as the excitation source; compact design and low maintenance requirements.
3. Rubber spring suspension: Absorbs vibration, reduces impact on the foundation, and prolongs equipment service life.
4. Adjustable design: Amplitude and bar spacing are adjustable to suit different material characteristics and working conditions.
5. Double layer screening (optional): Optional second layer screen mesh for enhanced separation precision of fines and soil.

Advantages of Vibrating Grizzly Feeder

1. High-efficiency screening, reduced back-end load: Small particles and soil are rejected in advance, lessening the crusher’s load and boosting overall production capacity.
2. Low noise, smooth operation: Rubber spring support ensures soft start/stop, suitable for noise-sensitive environments.
3. Simple structure, convenient maintenance: Vibration motor requires minimal lubrication; easy to service the whole machine.
4. Flexible installation: Compact size, allowing for fixed or mobile layouts.

Working Principle of Vibrating Grizzly Feeder

The vibration motor drives the exciter, transmitting excitation force to the material trough via the spring system, causing periodic linear vibration. Material is tossed and moves forward by vibration, while fines and soil fall through the gaps between the bars for pre-screening. Large materials are then conveyed smoothly to crushing equipment for further processing.

Application Areas of Vibrating Grizzly Feeder

1. Mining industry: Coarse screening and feeding before primary crushing of metal and non-metal ores.
2. Sand and gravel aggregate plants: Provides uniform, stable flow to primary crushers and removes stone powder/soil.
3. Coal system: Screens out coal sludge and improves crushing efficiency.
4. Mobile crushing plant: Compact design makes it ideal for mobile equipment configurations.
5. Metallurgy, chemical, building materials industries: Front-end screening and conveying to enhance system stability and automation.
