A drum press for separating liquid from solid substance, the drum press consisting of two different sized, cylindrical, perforated drums rotating one within the other around different centers, between the envelope surfaces of which the liquid is pressed out from the substance being pressed, and the outer drum being provided with non-rotating end plates disposed with requisite clearance in relation to the rotating outer drum. The inner drum provided with a shaft passes through the non-rotating end plates of the outer drum with requisite clearance, and in its shell and in its end plates fixed on the shaft have been made, towards the shell, apertures, through which the liquid that has entered the drum during the pressing operation is enabled freely to flow out from the drum. |
