An active/resilient grinding media inside a tube containing a sample is oscillated rapidly by a homogenizer so that the active media is driven in a first direction until it impacts a first end of the tube, which causes it to deform and store an energy charge as it decelerates and stops, and it then accelerates rapidly in the second opposite direction under the discharging force of the stored energy toward the opposite second end of the tube. This cycle of the active media decelerating/charging and then discharging/accelerating is repeated throughout the entire oscillatory processing of the sample. The result is much higher velocities of the active media and therefore much greater impact forces when the sample and active media collide, producing increased efficiency in disruption and size-reduction of the sample particles.

A milling assembly for a ball mill has a housing for refining and separating a substrate and a collection vessel for retaining the refined substrate. The housing includes, in vertical order, a lid, at least one milling vessel for receiving milling balls, and a screen with a refining section and apertures. The collection vessel is releasably mounted to a bottom end of the housing. The housing has an orifice arranged therein. The orifice has a valve for selectively allowing gas to pass between an outside and an inside of the housing in an open position of the valve and to seal the housing against the outside in a closed position of the valve. The milling vessel includes a taper for receiving a sealing screw.

A method for determining parameters of a high-frequency vibrating mill with three grinding drums is disclosed. The mathematic modeling is established by applying the average parameter method and transfer function method; the synchronization-stability capability coefficient curve, and the dimensionless coupling torque maximum value diagram of the system are obtained by the characteristic analysis of synchronization and stability. Finally, the curves of rotational velocity of motors, displacements of mass bodies, and phase difference between exciters are obtained by the simulation, and the correctness of the method is verified by the comparison of characteristic analysis and simulation. The parameters of the high-frequency vibrating mill of the present invention can lower the technical requirements of exciters, reduce the loss of the exciters, increase the service life of the mill.

A vibratory drum includes a tubular drum having a longitudinal axis, and first and second vibratory generators disposed laterally relative to the longitudinal axis and opposite each other across the tubular drum. The drum also includes a frame to which the first and second vibratory generators are attached; and a plurality of resilient elements attached at a first end to the tubular drum and at a second end to the frame, whereby the vibratory motion of the generators is transferred to the tubular drum to impart a circular motion to material disposed in the tubular drum.

A system includes a platform having an upper surface and defining a recess having a floor, the recess configured to seat a dish, and a movable securing frame that is movably connected with the platform, the frame including a lift support having an upper surface that is movable along a path from a first location that is beneath the floor of the recess, through the recess, to a second location that is coplanar with the upper surface of the platform. A motor configured to cause oscillation of the platform and the movable securing frame can be used. A method of using the system can include placing a dish above a recess defined by an upper surface of a platform, and lowering the frame with respect to the platform, thereby seating the dish within the recess.
