Designed to optimize material supply efficiency in production processes, the GZ Electromagnetic Vibrating Feeder is an automated feeding system driven by electromagnetic excitation force. It delivers quantitative, uniform and continuous transfer of bulk, granular or powdery materials—including ores, coal and grains—from storage hoppers to downstream receiving equipment, and is widely used in metallurgy, mining, chemical, building materials and grain processing industries.
Introduction
GZ electromagnetic vibrating feeder is an automated feeding device driven by electromagnetic excitation force. It is designed to transfer bulk, granular or powdery materials such as ores, coal and grains from storage bins to receiving equipment in a quantitative, uniform and continuous manner. By optimizing material supply efficiency in production processes, it has found extensive applications in metallurgy, mining, chemical, building materials and grain processing industries.
Working Principle
The GZ electromagnetic feeder uses a silicon-controlled rectifier (SCR) half-wave rectification circuit to control the current in the electromagnetic coil, generating periodic electromagnetic force to drive the trough vibration. During the positive half-cycle, the electromagnetic force pushes the trough backward, storing energy in the main spring; during the negative half-cycle, the spring releases energy, driving the trough forward to form a continuous vibration cycle. Materials are thrown up and move forward in a parabolic trajectory under vibration, reducing direct friction with the trough and minimizing wear. The feeding speed and flow rate can be precisely controlled by adjusting the excitation force or frequency.
Key Features
1. High Energy Efficiency :
-
Adopting the low-critical near-resonance principle, its power consumption is significantly lower than that of traditional mechanically driven equipment. The electromagnetic force acts directly on the material, resulting in minimal energy transmission loss.
2. Precise Controllability :
-
It supports stepless adjustment of feeding volume, meeting the strict requirements of automated production lines for material proportioning. With instant start-stop and flow adjustment capabilities, it adapts perfectly to complex process demands.
3. Superior Structural Design :
-
It features compact size, light weight and no lubrication requirements, leading to extremely low maintenance costs. A fully closed structure is optional to prevent dust spillage, complying with the latest environmental protection standards.
Applications
GZ electromagnetic feeders are mainly used in the following industries :
-
Mining and metallurgy: Loading and conveying of ores, coke and slag
-
Building materials and chemical industry: Quantitative supply of cement, fertilizers and powdery raw materials
-
Grain processing: Uniform feeding for grains and feeds, and automated packaging lines
-
Special scenarios: Closed conveying in high-dust environments and short-distance transfer of high-temperature materials
