The control panel status before replacement

3, The production before replacement.

The production of April, May,June, July,August and September as below:

2, Parts replaced.

1, Replace and optimize the cone of separator to reduce the abrasive to enhance the efficiency.

2、 Change the guard vanes

3、Replace the new upgraded rotor which is optimized with different vanes and angle of flow. Meanwhile , we add the flange on the top to reduce the abrasive to improve the efficiency.

2、Change the labyrinth seal

5, The efficiency after replacement.

Based on the same working conditions, the production has been improved as 5% from 435T/H to 455-460T/H.
