How to work

Screen changing processing

1)breaker plates with screen pack in operating position

2)one slide bar is pushed out (driven by the hydraulic unit)

3)screen is changed, the blocked screen pack is replaced by the fresh one.

4)Air bleeding. The slide bar with fresh screen pack is pushed into the body of screen changer, and theair bleeding system begings to work at the same time

Then the other slide bar repeat above steps.
