ABSTRACT:
An apparatus for clarifying especially a select portion of the slurry content of a material reducing machine sump, the apparatus having a chamber providing a space into which such select portion of the sump slurry content may flow into engagement with a filter, the liquid component thereof passing through the same and back to the sump, individual and opposite acting pneumatic and hydraulic pressure producing means for inducing the mentioned flow into the chamber and engagement with and through the filter and return to the sump.
A method for clarifying a select portion of the slurry content in service of a material reducing machine sump in which a confined space exterior of the sump is subjected to a negative pneumatic pressure transmitted to the sump from such space through a conduit positioned that the free end thereof is in a selected slurry containing zone in the sump, thus to flow the slurry into the confined space and into engagement with a filter therein contained; applying a negative hydraulic pressure to the filter to draw the liquid component of the slurry through the filter with a greater pull than the pull exerted pneumatically within the chamber and flowing the filter passed component of the slurry back to the sump.
