A vibratory screener apparatus has a housing with upper and lower ends, the lower end having a first mounting area characterized by a first attachment diameter. A drive assembly is employed to vibrate the apparatus. The drive assembly has a second mounting area characterized by a second attachment diameter to mount the frame to the drive assembly. An adapter frame is disposed between the drive assembly and the lower end of the housing. The adapter frame has a first end and a second end, the first end is characterized by the first attachment diameter and is attached to the lower end of the housing. The second end is characterized by the second attachment diameter and attached is to the drive assembly.

A flip-flop screening machine includes two screening machine side walls and transverse supports which carry screen panels. The transverse supports are provided as a powered transverse support and as a non-powered transverse support. The transverse supports are arranged between the two screening machine side walls in a transverse direction of a direction in which a screened material is conveyed. At least every second of the transverse supports is provided as the powered transverse support. Each powered transverse support performs oscillations and/or vibrations with movements in a transverse direction of a longitudinal axis of the powered transverse support to alternately compress and stretch the screen panels. Each powered transverse support has over a substantial part of a length or over an entire length thereof a separate oscillatory or vibratory drive which is arranged between the two screening machine side walls.

A method is described for operating machines (10) having moving parts and arranged jointly on a support (32), said parts being moved periodically with substantially the same frequency, and wherein the phase of an oscillation of one machine (10) in relation to the phase of an oscillation of a further machine (10) is controlled by shifting the phases with respect to one another such that the amplitude of an oscillation of a structural part, for example of the support (32), remains below a predefined maximum value.

A system and method for a vacuum driven separating device is disclosed.

A separator attachment for use with a vibratory apparatus, the attachment including a housing mountable to a vibratory apparatus below a material-conveying surface of the vibratory apparatus, the housing defining a pressure chamber with an inlet and an outlet. The housing has at least one wall with a wall surface having a first end disposed proximate to the outlet of the pressure chamber and a second end. The attachment also includes a deflector plate with a deflector plate surface having a first end disposed proximate to the outlet of the pressure chamber and a second end, the deflector plate surface facing the wall surface. The deflector plate is translatable relative to the at least one wall to vary the spacing between the deflector plate surface and the wall surface. A system including a vibratory apparatus and the attachment may also be defined.
