摘要： A rotor (1) for a self-aspirated flotation cell (100) includes a body (2) having a base (25), and a bottom surface (19) that may be frustoconical. The rotor (1) may have a plurality of vanes (8) extending radially-outwardly from the body (2). A pumping cavity (9) may be centrally disposed within the rotor (1). The pumping cavity (9) may be defined below the bottom surface (19) and between inner surface portions (22) of the plurality of vanes (8). The plurality of vanes (8) may each extend from an upper vane surface (10) to a lower vane surface (18). The lower vane surfaces (18) may extend beyond the bottom surface (19) of the base (25).

摘要： A disperser hood (1) for a self-aspirated flotation cell (100) includes a collar (2), and a conical member (4) extending downwardly and radially-outwardly from the collar (2). The disperser hood (1) may be characterised in that it further comprises a plurality of vanes (6) extending downwardly from the conical member (4). Each of the plurality of vane (6) may have a lower side (8), a radially-inner side (9), and an external radius, curve, or chamfer (7) extending between the lower side (8) and radially-inner side (8).

摘要： A system for the continuous monitoring of wear is disclosed. The system comprises a flotation cell [1] having at least one flotation component [2, 4, 5, 6, 7, 8, 13]. At least one detector [9] is provided to the at least one flotation component, and at least one sensor [10] is provided to the flotation cell [1] which is configured to communicate with the at least one detector [9] during operation of the flotation cell [1]. In use, the at least one flotation component wears away and ultimately affects a function of the least one detector [9]. The at least one sensor [10] is configured to monitor said function of the least one detector [9]. When the at least one sensor [10] detects a change in the signal of the at least one detector [9], an operator is notified that maintenance or flotation component replacement may be necessary.
