The second crushing blade is adjusted to move substantially harmonically back and forth along a linear path.

Abstract: The invention relates to the field of the acceleration of material, in particular a stream of granular or particulate material, with the aid of centrifugal force, with, in particular, the aim of causing the accelerated grains or particles to collide with an impact member at such a velocity that they are crushed, and involves at least one sliding member (2) that is pivotly attached and centrifugally locked to the rotor (1) only along the side of the sliding member that is facing the rotor such that the attachment members (8,9) are located at a position essentially below the plane (22) with on it the outer edge (12) of the centre face (5). This has the advantage that the wear material is more effectively used such that less throw-away material remains, more sliding members can be placed on the rotor, a longer operation time is achieved, attachment members are not damaged when the sliding member wears through and that replacement is easier and special securing can be avoided.

Abstract: A gyratory crusher includes a crushing head on which a first crushing shell is mounted, and a frame on which a second crushing shell is mounted. The crusher has a thrust bearing which is made up of horizontal bearing plates and which is located between a vertical shaft and a piston arranged vertically below the vertical shaft. The crusher further has a first space, which is adapted to receive a variable amount of pressurized liquid, the first space being defined by the piston and a piston housing formed in the frame, and a second space which is adapted to receive, by way of a duct, pressurized liquid from the first space, the second space being located between the vertical shaft and the piston and at least partly accommodated in an opening in at least one of the bearing plates. The first space and the second space are adapted, by the liquid, to transmit forces from the crushing head to the piston housing, in order that the load on the thrust bearing is relieved.

Abstract: The invention relates to a device for the alignment and location of a sample (7), such as pills or tablets, for carrying out a further method step, such as a hardness test, with the aid of two opposing jaws (2, 3, 21), which may be moved relative to each other, the movable compression jaw (2) of which displaces the sample (7) along a guide track on to the fixed counter-jaw (3, 21), in order to begin the further method step with the sample (7). The forward movement of the movable compressing jaw (2), along with the sample (7) towards the fixed counter-jaw (3, 21) is continuously interrupted, the compressing jaw (2) being drawn backwards and driven forwards, such that the sample oscillates about the rest position thereof and then the compressing jaw (2) continues the movement towards the counter-jaw (3, 21) until the sample (7) reaches said counter-jaw (21).

The blades carry out at the same time a shearing movement and a swivelling movement around an axis by means of a crank mechanism.

Abstract: Rubber particles having textile and/or metallic inclusions are treated by first placing the particles on a support surface and then pressing the particles against the support surface in a direction transverse to the support surface with a surface of a press body exerting a pressure of in excess of 10 kg/cm.sup.2 without contacting the surfaces with each other. Both of the surfaces are nonsmooth. In accordance with the invention the support surface and the press body are relatively displaced in a direction generally parallel to the support surface to subject the particles to shear.

Abstract: A feeder/crusher machine for use in underground coal or ore mines for receiving and crushing mined material and feeding the crushed product to a stationary conveyor in the mine material transport system. It comprises a tramming unit supporting a feeding and crushing unit having an elongated body with a crushing section located intermediate receiving and discharge sections at opposite ends of the body. A conveyor has an upper, carrying run movable through the crushing section in a horizontal plane. A pair of breaker drums are mounted immediately above the conveyor in the crushing section and are rotatable about transversely spaced, parallel vertical axes. Because the breaker drums are rotatable about vertical axes, teeth on their peripheries move horizontally, parallel to the plane of the conveyor carrying run. Further, the teeth move in the same direction as the conveyor at the location between the drums where crushing occurs.

Abstract: A grinding apparatus for thoroughly crushing, particulating and/or fragmenting materials that are firm or soft. The apparatus is particularly suitable for grinding plant leaf tissue. The grinding apparatus includes a rotatable reamer and a cup for receiving the reamer. The reamer has teeth that form a grinding surface, these teeth extending radially outward from a center point of the grinding surface. A second set of teeth form the inner bottom surface of the cup and provide another grinding surface. The cup teeth correspond to the reamer teeth so as to mesh therewith and produce a camming action during rotation of the reamer.
