Electromagnetic vibrating feeder

Product Overview

Electromagnetic vibrating feeder is a kind of high-efficiency and energy-saving quantitative feeding equipment, which is used to evenly, quantitatively and continuously convey lumpy, granular or powdery materials from the storage bin to the receiving device. It is the key equipment to realize the automation of production process and flow operation, and is widely used in mining, metallurgy, coal, electric power, chemical industry, foodstuff, glass, refractory material and other industries with its precise control, low energy consumption and compact structure.

Core advantages

1. Precise and controllable feeding

• Stepless adjustment: By adjusting the rectification voltage of the silicon controlled rectifier, stepless and linear adjustment of the feeding quantity can be easily realized to meet the requirements of precise quantitative feeding.

• Immediate response: quick start and stop, no material stagnation in the trough, easy to realize automatic control and centralized regulation.

• Stable operation: Driven by half-wave rectifier current, high working frequency ( 3000 times/minute ), smooth and even feeding.

2. Energy efficient and durable

• Extremely low energy consumption: no need to drive motor, only driven by electromagnetic force, low power consumption, very low operating costs.

• Low wear and tear, long service life: the material in the trough is slightly thrown movement, and the trough friction is small, so the wear and tear on the equipment is very small, long service life.

• Simple structure: no rotating parts, almost no parts that need lubrication, less maintenance workload.

3. Convenient installation, flexible application

• Small size and light weight: compact structure, small space occupation, easy to install and arrange in the existing production line.

• Flexible installation: can be installed by hanging or support, which can be adapted to different site layout requirements.

• Low noise operation: Compared with other feeding equipment, the operation noise is lower, improving the working environment.

Working Principle

Electromagnetic vibrating feeder adopts the principle of electromagnetic drive and mechanical resonance:

1. Power supply: The electromagnetic coil is energized by a single-phase, half-wave rectified current.

2. Generate suction: in the positive half of the current, the coil generates pulse electromagnetic force, attracts armature, makes the trough move backward, and the main spring stores potential energy.

3. Release elastic force: In the negative half of the current, the electromagnetic force disappears, the main spring releases energy and pushes the trough forward.

4. Cyclic vibration: The power supply alternates at 50Hz per second, which makes the trough vibrate reciprocally at a frequency of 3000 times per minute.

5. Material conveying: As the bottom plane of the trough body and the line of action of the excitation force into a certain angle, the material in the trough body is subject to cyclic excitation force, along the parabolic trajectory of continuous forward jumping movement, so as to realize the uniformity of the material.

6. Control flow: Adjust the output voltage by changing the conduction angle of the SCR to control the amplitude of vibration, and finally realize the stepless adjustment of the feeding quantity.

Technical parameters (example)

Note: The feeding capacity, tank size and other parameters of specific models should be determined according to the actual demand.
