Abstract
An apparatus for fractionating suspensions includes a tubular strainer (1) rotatable about a horizontal axis, and a spray device (5,7) arranged to spray the suspension against the strainer. The strainer has at least two strainer sections (2) spaced from each other and disposed axially in series along the tubular strainer. The spray device has at least one row of spray nozzles (7) extending axially along the tubular strainer and adapted to spray the suspension onto the strainer from above the strainer.
Claims8
An apparatus for fractionating suspension, including
- a tubular body (1,16,39) having a centre and a circumferential strainer (2,17,30,32,33),
- drive means (14) arranged to turn the tubular body such that the strainer is turned at least intermittently about an axis extending through the centre of and substantially axially along the tubular body,
- spray means (7) arranged to spray a suspension to be fractionated against the strainer such that a fine fraction of the suspension penetrates the strainer and a coarse fraction of the suspension is rejected by the strainer, and
- fine fraction discharge means (8,9) for discharging the fine fraction from the apparatus, characterized in that
- the tubular body (1,16,39) is positioned such that said axis extends substantially horizontally,
- the strainer comprises at least two strainer sections (2,17,30,32,33) spaced from each other and disposed axially in series along the tubular body, and
- the spray means comprises at least one row of spray nozzles (7) extending axially along the tubular body and adapted to spray the suspension onto the strainer sections from above the tubular body.
