Tensioner systems, methods and apparatus are described for tensioning drive belts of vibratory screens.

A quantitative infrared chemical imaging method to determine the concentration of a desired high value product in a milling process is used as a basis to optimize the milling process by changing operational parameters, such as sieve size. In a dry milling process, the method can be used to determine the concentration of purified endosperm within heterogeneous solid particulate mixtures containing endosperm and nonendosperm botanical parts. The imaging component accommodates the analysis of particle size statistics for each component of the mixture, based upon the chemical structural characterization. Timely chemical composition and particle size analyses enables informed selection for the optimization of physical separation for the processing of granular solids. The method involves changing sieves within the sifting apparatus based on chemical imaging to provide smaller or larger screen openings to improve separation of endosperm and nonendosperm material from the ground product.

A screening assembly for a mobile bulk material processing apparatus is capable of adjustment of its position with respect to the base frame of the mobile bulk material processing apparatus in order to facilitate the transfer of material from the screen on to the processing unit, such as a crusher, by optimizing the height and the angle of operation of the screening assembly. The screening assembly is also capable of being folded into a compact arrangement, which is compliant to transport regulations, while also being convenient and safe for the operators. The screening assembly includes a base frame and at least two linking elements coupled at pivotable joints in such a way that when in operational position, the two linking elements are configured to adjust the height and the angle of inclination of the screen box to facilitate transfer of material from the screen to the crusher.

An orbital shaker device (1) for biotechnological and/or biomedical applications comprises a frame (10), a platform (15) for receiving biotechnological and/or biomedical containers (50), eccentric couplings (13, 14) for allowing an orbital movement of the platform (15) relative to the frame (10), counterweight units (17, 18) for balancing the orbital movement, and at least one motor (19) for driving the eccentric couplings (13, 14). The device comprises two eccentric couplings (13, 14) arranged near respective opposite edges (27, 28) of the platform (15), while each counterweight unit (17, 18) is arranged approximately in the plane of the combined center of gravity of the platform (15) and the containers (50). Furthermore, both eccentric couplings (13, 14) are driven by the motor (19) or motors, either directly or indirectly. In this way, an optimal vibration compensation is achieved while allowing an imaging unit (40) to be mounted underneath the platform (15).

A step-down spring seat assembly secured to a vibratory screen machine is configured to receive one or more universal adapter plate assemblies, to which one or more compression springs is secured. The universal adapter plate assemblies are secured to a top surface of the step-down spring seat assembly, and one or more spring guide castings are connected to the one or more universal adapter plate assemblies. Compression springs are positioned atop the spring guide castings, and are secured to a top adapter plate assembly that is connected to one or more universal adapter plate assemblies positioned above the one or more compression springs.
