Abstract: The invention relates to a press drive for a press or a press having a press drive. The invention also relates to a method for controlling the press drive by means of a control unit. The press drive is used for moving a ram of the press in a stroke direction H between an upper return point OT and a lower return point UT. It comprises a knee lever gear having a first lever and a second lever. A connecting rod engages on the knee lever of the two levers and is connected on the other end to an eccentric of an eccentric drive. The control unit can drive the eccentric drive in a first operating mode B1 or a second operating mode B2 or, in particular, also a third operating mode B3. In the first and the second operating modes B1, B2, the eccentric oscillates in a respectively different angle region W1, W2 about a rotation axis D of the eccentric drive, thus resulting in different force and movement states of the ram in both operating modes.

Abstract: A solid-bowl centrifuge that includes a drum rotatable about a horizontal axis of rotation and a screw arranged in the drum. Also included are a continuous solids discharge located at a first end of the drum and a continuous liquid discharge located at a second, opposite end of the drum. Further included is at least one discontinuously acting outlet opening including a closure device.

Abstract: A screw centrifuge including a drum having a rotor, the drum having two axial ends and a horizontal axis of rotation, and a screw arranged in the drum and configured to rotate relative to the drum at a speed different from a rotation speed of the drum. Also included is a bearing device located at each axial end of the drum and configured to bear the drum. Each bearing device includes a housing and a pair of cantilevers extending in opposite directions away from the housing. Further included is a pair of spring elements associated with each bearing device and configured for sprung support of the drum. Each spring is arranged between one of the cantilevers and a frame, the spring elements being located at each axial end of the drum.

Abstract: A vehicle for harvesting espalier fruit, such as berries or grapes, and for further processing to a must on the vehicle. The vehicle comprises a frame configured to reach over a row of plants to be harvested in an area of a u-shaped recess of the vehicle. Also included are wheels on both sides of the u-shaped recess and arranged on the frame. Further included is a picking device to separate the fruit from a remainder of the plants. A solid-bowl screw-type centrifuge is arranged directly on the vehicle, which solid-bowl screw-type centrifuge separates and clarifies a fruit mash into at least a solids phase and a liquid phase.

Abstract: Process for recovering metals from metal-containing wastes and materials, characterized in that the metal-containing waste is preferably introduced continuously into a process chamber, treated thermally with continuous intensive mixing, the organic components are continuously removed and subsequently oxidized and the metal-containing components, preferably as metal conglomerates, and the further inorganic metal-free components are discharged essentially continuously from the process chamber and a plant for carrying out the process.

Abstract: A full-jacket helical conveyor centrifuge including a rotatably disposed drum and a drive device for the drum. The drive device for the drum includes at least one electromechanical direct drive having secondary elements arranged on the outer periphery of the drum or on the outer periphery of a part non-rotatably connected with the drum. Primary elements are arranged radially outside the secondary elements at a distance from the secondary elements and without contact. A propulsion force is generated by an electromagnetic field of travelling waves.

Abstract: In a press having a plunger supported so as to be movable linearly back and forth by drive means which include at least one servomotor in combination with a rotatably supported inertia structure connected for rotation with the servomotor, the inertia structure has an inertia moment which is small enough to permit reversal of the servomotor within a stroke length of the plunger so that the stroke of the plunger is adjustable under the control of a control device connected to the servomotor for controlling its operation.

Abstract: Process for removing mercury from flue gases of high-temperature plants, in particular power stations and waste incineration plants in which a bromine compound is fed to the multistage furnace and/or the flue gas in a plant section downstream of the furnace, the temperature during contact of the bromine compound with the flue gas being at least 500° C., preferably at least 800° C. The combustion is carried out in the presence of a sulphur compound, in particular sulphur dioxide. Subsequently to the furnace, the flue gas is subjected to an optional multistage cleanup for removing mercury from the flue gas, which cleanup comprises a wet scrubber and/or a dry cleanup.
