Electromagnetic coal vibrating hopper feeder is widely used in industries of metallurgy, mining, coal, building meterials, chemical, electric power, foodstuffs, machinery and etc. It can feed bulk shape material, granular material, and power material from storage silo or funnel uniformly, continuously and quantificationaly to various receiving equipments, such as belt conveyor, bucket elevator, screening equipment, crusher, grinder, etc. And also it can be used in the automatic system, and where feeding accuracy requirement is high.
1. Exclusive vibrating technology.
2. Small size and light in weight.
3. Simple structure, easy to install and use, low maintenance cost.
4. High efficiency and feeding capacity, high working frequency and low electric consumption
5. Good operational reliability and easy adjustment
6. No pollution.
When the power is on, the electric current passes the excitation coils, which creates a magnetic field. The magnetic force changes into vibrating force, which forces the transmission trough body to make simple harmonic vibration or similar to simple harmonic vibration in a certain direction. When the acceleration of its vibration achieves some certain value, the materials will make continuous and small throws or slides along the transmission direction in the transmission trough body, which causes the forward motion and transmission of the materials.
