<p>When a predetermined amount of separated sludge has accumulated in the peripheral part of the centrifuge rotor, a sensing device automatically opens outlets for the discharge of sludge. To provide substantially constant time intervals between consecutive openings of these sludge outlets, the feed rate to the centrifuge is automatically decreased in response to a shortening of these time intervals and automatically increased in response to a lengthening of these time intervals.</p> |
