2、External bearing rotary feeder performance advantage

External bearing rotary feeders have the following advantages.

1. Flexible adjustment

Some External bearing rotary feeders are equipped with variable frequency governors, which can adjust the rotating speed of the impeller according to the actual demand, thus flexibly controlling the conveying quantity of materials.

2. Continuous feeding

It can evenly and continuously supply materials into the clinker pipe, ensuring the stability and continuity of material transportation.

3. High sealing property

The design of special sealing structure enables the External bearing rotary feeder to maintain high sealing performance during transportation and reduce material leakage and gas reflux.

4. Compact structure and beautiful appearance.

The External bearing rotary feeder adopts the principle of planetary rotation, and the input and output shafts are on the same axis, with compact structure, small volume and light weight.

5. Smooth operation and low noise.

Uniform and stable feeding process, stable discharging operation, low noise, few faults and long service life.

4、Structural advantages of External bearing rotary feeder

The External bearing rotary feeder has the following structure

1. Rotor and shell

The rotor is the core component of the External bearing rotary feeder, and usually consists of several blades, which rotate in the cylindrical casing. Materials fall from the upper hopper and are filled in the spaces between the blades. With the rotation of the impeller, they are transported to the lower part and discharged from the shell to protect the internal mechanism and seal, and prevent the leakage of materials and the entry of external impurities.

2. Equalizing exhaust port

The side of the External bearing rotary feeder body is provided with a pressure equalizing exhaust port, which can exhaust the high-pressure gas brought by the rotation of the impeller, reduce the phenomenon of gas ejection, and facilitate the smooth falling of materials.

3. sealing element

Seals are used to ensure the sealing performance of the External bearing rotary feeder in the working process and prevent material leakage and gas backflow. High-quality seals can improve the working efficiency and service life of equipment.

4. Motor and transmission device

The motor provides power for the External bearing rotary feeder, and the power is transmitted to the impeller through transmission devices (such as gears and sprockets) to make it rotate. The transmission device shall be designed to ensure smooth and reliable power transmission.

5. impeller

Impeller is the key part of the External bearing rotary feeder to realize material transportation. Its structural design is reasonable, which can ensure the uniform distribution of materials in the spaces between the impellers and be transported smoothly with the rotation of the impellers.

5、Advantages of External bearing rotary feeder principle

External bearing rotary feederthe principle is simple.The motor reducer drives the impeller to rotate in the cylindrical casing. Materials fall from the upper hopper and are filled in the spaces between the impellers. With the rotation of the impellers, the materials are transported to the lower part and discharged. At the same time, the exhaust port exhausts the high-pressure gas generated by the rotation of the impeller, which reduces the phenomenon of gas ejection and ensures the continuity and stability of material transportation.，generally, it is composed of equalizing exhaust port, protective devices (such as sprockets, sprocket covers, etc.), motor reducing gear, rotor and shell, vent and other major components，the advantage is Excellent sealing structure, preventing dust from leaking out and prolonging the service life of motor parts and lubrication system.、By adopting the principle of planetary rotation, the input and output shafts are on the same axis and directly connected with the motor, which makes the whole structure compact, beautiful and novel in shape, small in volume and light in weight.、Impeller, bushing and other key components are made of high-quality wear-resistant materials, which can withstand the friction and wear during material transportation and prolong the service life of the equipment.、Using the principle of planetary rotation, the input and output shafts are on the same axis and directly connected with the motor, which makes the whole structure compact, beautiful and novel, small in size and light in weight.、Can evenly and continuously feed materials into the clinker pipe to ensure the stability and continuity of material transportation.，it is widely used in dock, building materials cement, chemical industry, energy mining industry, dock and other industries，can be customized according to user's needs.。

6、External bearing rotary feeder advantage

The advantages of External bearing rotary feeder are as follows:

1. Good sealing performance

Excellent sealing structure, preventing dust from leaking out and prolonging the service life of motor parts and lubrication system.

2. overpower protection

Some External bearing rotary feeders also have overload protection function, which can automatically stop protection in case of abnormal situation to avoid equipment damage.

3. Flexible configuration

By adjusting the parameters such as External bearing rotary feeder speed or blade angle, the conveying capacity of materials can be flexibly adjusted to meet different technological requirements.

4. Compact and beautiful

By adopting the principle of planetary rotation, the input and output shafts of the External bearing rotary feeder are on the same axis and directly connected with the motor, which makes the whole structure compact, beautiful and novel in shape, small in size and light in weight.

5. Strong overload capacity

Low impact inertia force, suitable for frequent starting and reverse rotation.

External bearing rotary feeder

External bearing rotary feederis the main equipment for conveying bulk materials.，multifunctional, with functions such as dust removal equipment discharges dust., blowing-in, prevent gas or dust leakage, material handling and ensure air tightness of the system。
