Abstract (en)
[origin: EP1393872A1] The method involves homogeneously mixing the sludges removed from the cutting machine with water before reaching the hydrocyclone separating the minute grains. Said mixture is carried out in an ejector (4) which receives the sludges through an inlet (7) and pressurized water through the injector (5). In vertical position, it sends the mixture jet into the interior of a body (1), wherein a partition wall (8) is placed inside said body to support a bridge (9) defining an impact surface (10), which provokes a first homogenization of the mixture together with subsequent impact of the fragmented jet against the side wall of a body (1). The jet then goes through perimeter holes (11) of the partition (8) into a lower chamber (13) in which the jets passing through said holes impact a slanted plane (14) thereby generating a second homogenization phase before reaching the outlet (15) defmed by the slanted plane (14) in the direction of the tube (17) communicating the ejector-mixer with the hydrocyclone. <IMAGE>
