Screw Press Upgrades Riemer Hubert - 2010

The Situation:

To low feed consistency effects a to high inlet pressure:

To high inlet pressure leads to plugging of the dewatering holes by the fiber

bundles

Plugged screen basket holes can not dewater - the dewatering action is moved

forward to the next sections until the press suffers completely from pumping

through instead of dewatering

Shut downs and uneven operation are the results
