Attentation: 1. The processing capacity and motor power listed are designed according to the conveying particles, and other materials can be redesigned according to the requirements of the users.

 

       2. The inside and outside diameter is designed according to JB/T81-94 pressure grade PN0.25MPa, and can be redesigned according to the requirements of users.

 

       3. Special materials, special working conditions, can call communication, the factory can design and manufacture according to special requirements.

 

6. Characteristics of star-shaped feeder for powder and particle:

 

1.        Bite-proof design at feeding entrance to avoid particle shearing in operation. Reduce equipment vibration and fault risk, reduce particle breakage, improve transport quality.

 

2.        Internal polishing process to avoid the adhesion of powder materials, and phenomenon of no feeding in the bridge.

 

3.        Strengthen bearing support Design, improve rotor fit Precision

 

4.       The self-lubricating PTFE packing seal is adopted at the rotary shaft, which reduces the wear of the packing and reduces the dust leakage.

 

5.        Compact structure, small space.

 

7. Features of high concentration star feeding machine for powder and particle (suitable for high pressure air conveyance and high airtight requirement).

 

1.        Suitable for inside and outsidet pressure range: 1 kg / cm 2 system pressure or pressure difference

 

2.        The special design of shell inside and outside section can effectively prevent the extruding and crushing of granular materials and prolong the life of equipment, it can safely start and improve the conveying quality even if the upper reaches are filled with materials.
