    Abstract: A flow disrupter in a tube chamber of a tube assembly for homogenizing sample materials includes a flow-disrupting body that extends generally transversely into the tube chamber and divides the tube chamber into two sub-chambers. The flow-disrupting body includes at least one narrowed flow passageway through which the sample flows back and forth in both axially reciprocating directions as the tube assembly is vigorously shaken at high speeds faster and more reliably than what can be accomplished by hand shaking. And the flow-disrupting body includes at least two flow-interrupting surfaces facing generally in opposite axial directions and against which the sample impacts in each respective axially reciprocating direction as the tube assembly is vigorously shaken. In this way, the vigorous high-speed shaking of the tube assembly including the flow disrupter results in significant particle-size reduction of the sample by mechanical shear, fluid shear, cavitation, and/or pressure differentials.

    Abstract: A grinder includes a double forced movement in which the movement of the grinding medium in the chambers of the grinder drum is forced by a vibrator device as well as by the drum itself. The combination of the vibrating movement of the rotating grinding medium, which is caused by the vibrator with the rotary movement of the grinding medium, in turn resulting from the rotation of the drum around an eccentrically shifted axis, significantly increases the centrifugal forces of the grinding medium and causes the creation of a layer of rotating grinding medium together with the grinded material inside the drum chamber, while the thickness of the layer is thereby differentiated.

  • Patent number: 7448566
    Abstract: The invention is a laboratory mill that allows small samples to be shaken, mixed, ground, homogenized or comminuted effectively within a small vial. The design is similar to a planetary mill but unlike those devices, neither axis of rotation is centered on the axis of the processing vessel. The design allows many vials to be processed at one time and even when the diameter of the vial is quite small, maintains the processing performance. The performance of the device when used as a comminuter is demonstrated showing that the device can comminute organic solids down to a median particle size of 1 micrometer with a narrow size distribution. Because the processing takes place within a vial, the mill does not require cleaning between samples which allows the application of the device in automated or high throughput systems.

  • Publication number: 20080156230
    Abstract: The invention relates to a method for producing transparent dioxazine pigments. Said method is characterised by the use of an eccentric oscillating mill to crush a dioxazine crude pigment, said mill comprising at least one milling container that is mounted on the oscillating elements and an excitation unit that is rigidly fixed to said milling container. According to the invention, the excitation takes place in an eccentric manner on one side, outside the gravitational axis and the centre of mass of the milling container, thus generating inhomogeneous oscillations consisting of circular, elliptical and linear oscillations.

  • Patent number: 6887135
    Abstract: An apparatus and process of surface finishing golf balls prior to painting is provided. The apparatus and process make use of nylon loops as a finishing material that is used to abrade the surface of adjacent moving golf balls. Optionally, the abrading process between the nylon loops and the surface of the golf balls may be carried out in the presence of a continuous stream of water. As water is removed from the processing equipment, the removed water carries with it abraded material. The process provides for improved adhesion of the paint to the surface of the golf ball.

  • Patent number: 6880771
    Abstract: A tubular vessel is loaded with a combination of grinding media and a material to be ground. The vessel is capped to contain the grinding media and material therein. Grinding of the contained material is effectuated by reciprocating the capped vessel in a direction parallel to its longitudinal axis. The grinding media may comprise either a ball or a slug, and may further utilizing a plurality of balls, perhaps of different sizes. To increase volume, a plurality of vessels may be gathered together into a sample holder. The sample holder is them reciprocated in a direction parallel to the axes of the included vessels.

  • Patent number: 6334583
    Abstract: A Planetary High-Energy Ball mill is for producing nanosized powders and it includes: (a) a main axis which can not only rotate but also up and Down, (b) a roll-bearing to be fixed on nether end of the main axis, a revolvable plate to be fixed on the top of the main axis, and several able-swing shafts installed in the plate. (c) a plurality of planetary motion mill pots are fixed on the support canisters which are supported by able-swing shafts. (d) A stationary ring which is disposed coaxially with the main axis and serves as the orbit for mill pots. (e) impact bars on the bottom of mill pots using magnet technology to disperse doposited powders. The invention solves the problems of powders deposited on the bottom of mill pot, avoids tire ruption applied to private shaft which supports mill pots, improves stress distribution. So it capable for industrial-scale producing nanosized powders.
