The GZD series vibrating feeder is a continuous feeding device with a vibrating motor as the excitation source. It is widely used in industries such as sand and gravel, mining, metallurgy, building materials, and chemicals. It is mainly used for the uniform conveying of large materials before coarse crushing and has a pre-screening function. It is one of the indispensable key pieces of equipment in the crushing and screening production line.
Working Principle
The GZD series vibrating feeder uses two identical vibrating motors operating synchronously in opposite directions to generate a directional excitation force. When the eccentric blocks of the motors rotate, centrifugal force is generated, which, at specific phases, superimposes or cancels out, causing the machine body to vibrate forcefully on spring supports. The material then slides and is thrown along the inclined trough surface, moving continuously forward and achieving uniform feeding.
When the material passes through the bars or grates at the discharge end, finer materials smaller than the gaps can fall directly, serving as coarse screening; if screening is not required, a flat plate structure can be used.
Product Structure
The GZD series vibrating feeder mainly consists of the following components:
- Feeding trough: Bears and conveys materials, available in steel plate and grate structures;
- Vibrating motor: Provides excitation force, can be installed as an upper or lower vibrating type.
- Spring system: Includes metal helical springs or composite springs, used for vibration damping and stable operation;
- Spring supports: Support the entire machine and buffer the foundation load;
- Grate/bars: Enable pre-screening function, gap adjustable;
- Transmission device: Some models are equipped with a frequency converter for stepless speed regulation.
Product Advantages
-
Uniform feeding and stable operation
Smooth vibration prevents the receiving device from "crashing" due to uneven feeding, extending equipment life. -
Simple structure and convenient maintenance
Modular design ensures high component interchangeability, facilitating installation and maintenance. -
Pre-screening function
The grate structure removes mud and fine particles during feeding, optimizing the subsequent crushing process and improving system economy. -
Adjustable vibration force and controllable flow rate
The feed rate can be steplessly adjusted by adjusting the eccentric block angle of the vibrating motor or by adding a frequency converter, adapting to different working conditions. -
Low noise and low energy consumption
Using low-alloy structural steel (such as Q345C) and optimized elastic elements, it features low noise and low power consumption, making it suitable for cold regions (operating even at -40℃). -
Dustproof design
An optional enclosed body prevents dust leakage, improving the working environment.
