The classification of Explosion-proof Vibration Motor

1.According to the principle, explosion-proof vibration motor can be divided into explosion-proof asynchronous vibration motor, explosion-proof synchronous vibration motor and explosion-proof DC vibration motor etc.

 

2.According to the working place , explosion-proof vibration motor can be divided into coal mine use explosion-proof vibration motor and factory use explosion-proof motor.
3. According to the explosion protection principle , explosion-proof vibration motor types can be divided into the flameproof type, increased safety type, positive pressure type, no-spark type and dust & explosion-proof electrical motor, etc.

 

4.According to the matching equipment, explosion-proof vibration motor can be divided into explosion-proof motor for coal mine conveyor, coal mine winch, rock loader, coal mine fan, valve, blower, marine, lifting metallurgical hydrogenation device.

 

5.According to the nominal voltage and efficiency, explosion-proof vibration motor can be divided into high voltage type, high efficiency type, high slip ratio type and high starting torque type of explosion-proof motor.

The advantages and Principles of Vibratory Feeders

Vibratory feeders(as known as vibrating feeders,vibration feeders) is suitable for metal and coal feeding system. The materials will be discharged evenly onto the belt conveyor from bunker by using vibratory feeders and will form into a appropriate thickness and width of material layer. Applicable materials can be coal, ore, sandstone, sandy soil and other powder raw materials in food and chemical plant.

 Working principle:

The feeding process of vibratory feeders is achieved by the feeding chute doing linear reciprocating vibration periodically which is forced by the special vibrating motor. When the vertical weight of the feeding chute vibration accelerated speed is bigger than the gravitational acceleration, the material will be upthrown and jumped forward along a parabolic path. The feeding chute will vibrate and the material inside the feeding chute will jump forward continuously due to the continuous exciting of the vibrating motor, so that it can achieve the purpose of material feeding. 

The characteristics of the vibratory feeders mainly include the following parts:

1. It can easily control the discharge capacity. You can also control the discharge capacity (tons/hour) by using a inverter.
2. It applies to a wide range of materials, such as powder, granule, block and other materials.
3. Low maintenance cost , because of adopting resonance principle, so the vibration feeder has less power consumption and less wear characteristics.
4. It can be used in special conditions: according to different working condition, the vibrating feeder can be equipped with dust cover, liner plate, sealing part etc.
5. Smooth vibration and reliable operation.
6. Special grid design which can prevent material blockage. The clearance between grids can be adjustable.
7.Frequency conversion motor is optional, you can change the capacity by adjusting the motor frequency which is easy to control the feeding rate without starting motor frequently.
