<p>The separation of particulate solids of larger and smaller sizes from each other in a vibratory separator (10) which includes: a housing (12) with an inlet (22), a first outlet (24) for discharge of undersized particles, and a second outlet (26) for discharge of oversized particles, and one or more screens (28) supported in the housing (12) between the inlet (22) and the first outlet (24). Including the steps of introducing the solids to be separated into the housing (12) via the inlet (22), imparting to the housing (12) and thus also to the solids a single frequency vibration, thereby to induce vibratory transportation of particulate solids along the one or more screens (28), and converting the single frequency vibration of the housing into a sequence of mechanical pulses applied to an interface apparatus, to generate a multifrequency vibration of the screen and also of masses of agglomerates in engagement with the one or more screens (28).</p> |
