摘要： Vibratory screening machines that include stacked screening deck assemblies are provided. In some embodiments, at least one of the vibratory screening machines can include an outer frame, an inner frame connected to the outer frame, and a vibratory motor assembly secured to the inner frame for vibrating the inner frame. A plurality of screen deck assemblies can be attached to the inner frame in a stacked arrangement, each configured to receive replaceable screen assemblies. The screen assemblies can be secured to respective ones of the plurality of the screen deck assemblies by tensioning the screen assemblies in a direction that a material to be screened flows across the screen assemblies. An undersized material discharge assembly can be configured to receive materials that pass through the screen assemblies, and an oversized material discharge assembly can be configured to receive materials that pass over the screen assemblies.

摘要： A method is described for making a reinforcing wire frame for embedding in a moulded polymer support frame (10) over which woven wire cloth (158,159) is to be stretched and secured to form a sifting screen. The method involves locating lengths of cut wire (50) substantially equally spaced apart in a jig to form a first array. A second array of lengths of cut wire (56,60) is located over the first array with the lengths of wire in the second array being substantially at right angles to those of the first array. The lengths of wire in the first and second arrays are resistance welded at points of mutual intersection so as to form a first substantially rectilinear matrix. Lengths of cut wire (48) are located in a jig to form a third array, in which the lengths are also substantially equally spaced apart, and a fourth array of lengths of cut wire (54,58,62,64) is arranged over the third array with the lengths of the fourth array substantially at right angles to the lengths of wire of the third array, and the wires of the third and fourth arrays are also resistance welded at points of mutual intersection to form a second substantially rectilinear matrix. Protruding lengths of wire on at least two sides of the four sides of one of the rectilinear matrices are bent using a press so as to bend each protruding length first in a generally upward sense and then at a point nearer its end in a generally downward sense so that an end region of each protruding length extends parallel to a plane of the matrix but is displaced therefrom. Thereafter the displaced ends of the protruding lengths of wire of one matrix are resistance welded to protruding lengths of wire of the other matrix, to form the frame.

摘要： The present invention provides a screen system (8) suitable for use in a vibratory screen apparatus (1), and comprising: a screen element (11) and a support frame (12) therefor, as well novel screen elements (11) and mesh panels (19) therefor, and the use thereof. The screen element (11) consists essentially of a mesh panel (19) provided with first and second elongate support members (22, 23) extending along opposite end portions of the mesh panel (19). The support frame (12) has spaced apart first and second elongate frame elements (13, 14) for engagement with the screen element support members (22, 23) and further elongate frame elements (17, 18) extending there between for supporting the mesh panel (19). The screen element support members (22, 23) and said first and second frame elements (13, 14) are formed and arranged for secure interengagement in use of the screen system, with at least one of said screen element support members and the respective one of said first and second frame elements being formed and arranged so that when clamped together, the mesh panel (19) is securely held under tension against said further frame elements (17, 18).
