| 摘要 |
This invention relates to a separation system (10) for separating first solid particulate components from second solid particulate components having particle sizes which are smaller than that of the first solid components, wherein the first and second solid components are suspended in a liquid to form a mixture (12). The system (10) includes an endless screening belt/cloth (14) which is displaceable along a predetermined path. The screening belt/cloth (14) defines a plurality of apertures (16) which apertures (16) are of a suitable size to permit the second solid components to pass therethrough and to impede the passage therethrough of the first solid components. The system (10) also includes at least one roller (17) over which the screening belt/cloth (14) extends in a separating region (18). The roller (17) includes a plurality of protuberances (26) which protrudes from a body (22) thereof. The protuberances (26) are configured mechanically to engage with at least some of the apertures (16) of the screening belt/cloth (14) in order to break the surface tension of the mixture (12) provided on the separating region (18). |
