A centrifugal particulates solids separator comprises a rotatable separator drum 23 having one end wider than the other and means for rotating said drum about its axis. Slurry introducing means are included whereby slurry can be poured onto the inside of the slurry drum to form a slurry film 20, 21 on the inside surface 22 of the drum 23, and thereafter said film tending to migrate towards the wider end of the drum. Radially disposed scraper blade means 1 comprising a plurality of scraper blades 5 that adapted to scrape the inside surface of drum 23as it rotates. This preferentially causes denser particles 20 within the slurry to migrate towards the narrower end of the drum. Scraper blade 5, which is less than the thickness of the film of slurry 20, 21, allows less dense solid particles 21 and / or the liquid forming part of the original slurry to flow over the scraper blades 5 and out of the drum 23 from its widest end. Denser solid particles 20 are preferentially scraped and separated out of the drum via its narrower end. |
