Abstract
This invention provides a cleaning method for removing sediment from the inner wall of the rotary drum of a horizontal drum-type centrifugal separator which comprises charging a plurality of solid cleaning medium pieces such as globules, balls, cubes, rods, springs etc., into the rotary drum, supplying a cleaning liquid to the rotary drum, rotating the drum, and discharging the sediment together with the cleaning liquid. The solid cleaning medium is charged into the rotary drum either before centrifugal separation or at the time of cleaning after centrifugal separation.
