The invention discloses a hydraulic-type dual-network roll press master, which comprises a frame, a slurry inlet case and a slurry baffling apparatus are connected to the front end of the frame, a fragmentation spiral apparatus is connected to the rear end of the frame, several pressure roller devices are arranged from the front end to the rear end in order on the frame, several pressure roller devices are distributed on the frame in a parallel mode, and rotatable screen cloth are winded on several pressure roller devices. The hydraulic-type dual-network roll press master employs a hydraulic mode for replacing the screen, so that the replacing of the screen cloth is more convenient. When the screen cloth is worn and needs to be replaced, a non transmission terminal bolt is released, then a hydraulic jack is jacked and tightly locked, the screen is extracted for supporting, so that enough space is provided at the non transmission terminal for placing the screen cloth.
