Core Advantages

• Stable Vibration & Reliable Operation: Adopting imported technology vibration motor as the excitation source, the equipment runs stably with low noise and low power co GZT series vibrating feeder is a high-efficiency primary feeding equipment designed by absorbing Swedish and Finnish technologies, specially developed for mine crushing and screening production lines. It is mainly used for continuous and uniform feeding from the silo to the primary coarse crusher, and is equipped with pre-screening function to separate fine materials and soil, effectively reducing the load of subsequent crushers and improving the overall production efficiency of the production line.

  Working Principle

  Structural Composition

  Trough: Adopting a rigid structure composed of steel plate trough box, crossbeam and rib plate, connected by frame type ring groove rivets. The feeding end is a blind plate with an inclination angle of 0-5°, and the discharge end is a bar with an inclination angle of 15-20°, with wear-resistant manganese steel guard plate and bar to ensure high strength and wear resistance.

  Vibrator: Using box-type vibrator with an integral structure of external eccentric blocks, composed of box body, transmission shaft, transmission gear, rolling bearing and eccentric blocks. The amplitude can be adjusted by adding or subtracting counterweights, and the gear is lubricated by oil immersion, which is easy to install and disassemble.

  Transmission System: Composed of motor and V-belt, the motor is installed on the bracket with an adjustment device, which can realize smooth start-up and operation of the feeder and avoid transmitting vibration to the motor. It can be easily controlled manually or automatically to adjust the feeding amount.

  Elastic Support: High-strength compression springs are used for support at the feeding and discharging ends, which play the roles of vibration isolation, noise reduction and amplitude stabilization, reducing the impact of equipment operation on the foundation and ensuring stable operation.

  
  

  Key Parameters (Common Models)

• Excitation Source: Adopting a pair of vibration motors with consistent performance parameters as the excitation source, which are produced with imported Japanese technology. When the two vibration motors operate in reverse at the same angular velocity, the inertial force generated by their eccentric blocks overlaps or offsets repeatedly at a specific phase, forming a huge synthetic exciting force.

• Motion Mode: The machine body makes forced vibration on the supporting springs under the action of the synthetic exciting force, and drives the materials to slide and throw on the trough, so that the materials move forward continuously to achieve the feeding purpose, with stable vibration and no material flushing phenomenon.

• Pre-screening: Equipped with adjustable gap grid bars, fine materials smaller than the grid gap can pass through the screen and do not enter the crusher, which plays a pre-screening role and makes the crusher exert its function more effectively.

• nsumption, no material flushing phenomenon, and long service life.

• Adjustable Performance: The exciting force and bar gap are adjustable, which can flexibly change and control the feeding flow, and can be easily controlled manually or automatically to adapt to different working conditions and feeding requirements.

• Strong Impact Resistance: The frame-type ring groove rivet connection structure and wear-resistant manganese steel bar/guard plate make the equipment have high strength, strong impact resistance and wear resistance, and can bear the impact of large bulk materials.

• Easy Maintenance: Simple structure, light weight and small volume, modular design, convenient installation and debugging, quick replacement of vulnerable parts, low operation and maintenance cost, and convenient daily maintenance.

• Wide Adaptability & Environmental Protection: Widely applicable to mines, quarries, metallurgy, coal mines, building materials and other industries, suitable for feeding and pre-screening of block and granular materials. The closed structure can prevent dust pollution.

Typical Applications

It is widely used in mines, quarries, metallurgy, coal mines, building materials and construction waste recycling production lines. As the first process of the crushing line, it is installed under the silo/hopper and in front of the primary coarse crusher to realize continuous and uniform feeding and pre-screening, separate fine materials and soil, and ensure the stable operation of the entire crushing and screening line.

Difference Between GZT and ZSWT

• GZT: Adopts imported technology vibration motor as the excitation source, with box-type vibrator and ordinary bar structure, processing capacity of 30–2000t/h, compact structure, light weight, suitable for medium and large-scale primary crushing scenarios, focusing on stable feeding and simple pre-screening functions.

• ZSWT: Adopts double eccentric shaft vibrator, with stepped bar design to prevent material blockage, larger processing capacity (120–1500t/h), optional frequency conversion motor, more suitable for large-scale primary crushing scenarios with high feeding demand and easy material blockage.
