The feeder is a self synchronous inertial vibrating feeder which is widely used in mining, metallurgy, coal, building materials, light industry, chemical industry, electric power, food and other industries, for the massive, granular and powdery materials from the storage silo or hopper in uniform for the quantitative or the feed device to the subject，such as crushing, coal selection, screening, transportation, packaging machinery and other materials, ingredients and so on. The GZG series feeder is a common trough type, which is used for material feeding without special requirements. GZGF series feeder is a closed trough feeder, which is used for feeding large and volatile materials.
Structure of feeder
This vibration feeder can be matched with the back brake control box, which can make the feeder stop quickly in a short time and make the feeder pass through the vibration area quickly. In addition, it also has the function of overflow, overvoltage and phase breaking protection, and can also increase the function of energy consumption braking fast feeding, remote control and stepless speed regulation. The structure of the machine is shown in Figure 1 and Figure 2.

The features of vibrating feeder
This series of vibrating feeder has the following characteristics:
1). Small volume, light weight, simple and compact structure;
2). Easy installation and maintenance, low operating cost;
3). High efficiency and large feeding capacity;
4). Low noise and beneficial to improve working environment;
5). Low power consumption and high power factor;
6). The amplitude is stable, the operation is reliable, and it has strong adaptability to various materials;
7). Can be conveniently stepless adjustment of feeding capacity.
Specification of Electromagnetic vibrating feeder
Small volume, light weight, simple structure, convenient installation, convenient repair, low operation cost.
Adoption the principle of the mechanical vibration, and less energy consumption.
Change the volume of flow at any time.
Centralized control and automatic control of production process.
The electromagnetic vibrating feeder utilizes electromagnetic vibrating device to drive minerals to reciprocate in the direction of dip. When the vertical component of accelerated speed of feeder exceeds accelerated speed, minerals are tossed upward and leap forward in parabolic fashion. It takes 1/5 second to finish the rising and falling. The chute vibrates for one time and subsequently the minerals are tossed for one time. The chute vibrate at a frequency 3000/minute. Correspondingly, minerals are tossed upward and leap forward. So minerals can continuously and uniformly move forward and feeding is achieved.
