Abstract
A continuous separation system intended for the recovery of solids and/or liquid contained in slurries comprises an enclosed low speed rotary screen assembly mounted between a stationary casing under vacuum and a cover provided with a fixed scraper and into which circulates dry hot air. The arrangement is such that during operation a slurry is admitted on top of the rotating screen on one side of the scraper while liquid is recovered by suction into the casing leaving the solids which are washed and then dried before being scraped off and eventually removed on the other side of the scraper. The recovered liquid is automatically degasified into the casing before being pumped out therefrom. Throughput can be varied either by adjustment of the amount of material being fed into the system, or by varying the speed of rotation of the screen assembly, or both. Provision is made for cleaning the screen during operation.
