vibratory feeder for continuous uniform feeding of crushers

Vibratory Feeder Overview

The main function of vibratory feeder is not only to stabilize the material delivery, but also to pre-screen the material, remove small particles of fines, reduce the load of the main crusher, and improve the efficiency and service life of the whole crushing and screening process.
Vibratory feeder is widely used in mining, metallurgy, coal, electric power, building materials, chemical industry, refractory materials, glass, ceramics, grain, ports and other industries, and is an important part of the material conveying and screening system.

Features of Vibratory Feeder

1. High efficiency feeding: the vibration intensity is adjustable, which can adapt to the continuous feeding requirements of different materials and different output.
2. Strong impact resistance: the use of double eccentric shaft excitation structure, more stable operation, can withstand the impact load of large materials falling directly.
3. Reasonable structure: the body is mostly of slot or closed design, and the wear-resistant liner can be replaced to prolong the service life.
4. Screening function: the front end is equipped with a screen bar grid structure, which can realize coarse screening and reject fine materials such as soil and small stones.
5. Low noise, energy saving and environmental protection: the design gives full consideration to the requirements of vibration damping and noise reduction, quiet operation and convenient maintenance.

Advantages of Vibratory Feeder

1. High automation: it can be seamlessly linked with crushing equipment and electric control system to realize intelligent control, one-key start-stop, alarm shutdown and so on.
2. Modular design: easy to install and move, strong adaptability, suitable for mobile crushing plant, fixed process line and other scenarios.
3. Low operating costs: low energy consumption, low wear and tear, long maintenance cycle.
4. Strong adaptability: can deal with high humidity, high viscosity, high mud content of ores, coal and other complex materials.

Working Principle of Vibratory Feeder

The core of the vibratory feeder is the double eccentric shaft excitation source, which is driven by the motor to rotate the eccentric shaft, generating periodic vibration, so that the material makes linear or parabolic motion along the feeding trough. The material slides forward and stratifies in the trough, and the small particles fall through the sieve bars, thus realizing the synchronization of conveying and preliminary screening.

The vibration frequency, amplitude and inclination angle can be adjusted according to the actual demand, in order to meet the conveying control of different particle sizes and different flow rates. The bottom of the vibrating system is usually equipped with shock absorbing springs, which effectively isolate the vibration of the foundation and reduce the dynamic interference between the equipment and the foundation.

Application Areas of Vibratory Feeder

1. Mining and quarrying: conveying ore to rough jaw crusher, screening out fine mud at the same time.
2. Sand and gravel aggregate production: provide continuous feeding and pre-screening function for sand making system.
3. Coal industry: used in coal washing plant, coal silo and other process sections to convey raw coal, crushed coal.
4. Metallurgical industry: used for conveying raw materials such as coke, ore and furnace charge in iron and steel plants.
5. Cement and building materials: used to convey limestone, gypsum, clinker and other raw materials.
6. Chemical raw materials: conveying and primary screening of granular chemical products.
7. Agriculture and food processing: feed processing plant, grain screening and conveying.
