Abstract: A grab bucket, in particular motor-driven underwater grab bucket, has first and second half-scoops. The scoops can be moved relative to on another from an open position into a closed position by a hydraulic cylinder. The opening angle of the half-scoops is monitored by a sensor which is connected to a control and monitoring device. The sensor is integrated in the hydraulic cylinder and generates an actuating-travel signal which corresponds to the actuating travel of the hydraulic cylinder.

Abstract: A rotary compression press for cylindrical compacts, especially tablets, comprising a rotatably driven rotor including a die-plate and an upper and a lower ram guide for upper and lower rams cooperating with the die bores, and a pressure station with an upper and a lower pressure roller for applying a pressing power to the rams wherein the rams circumferentially have an annular tooth system which cooperates with an opposed tooth system in the area of a pressure station for the rams for the purpose of rotating the rams in the die bores thereof, characterized in that the opposed tooth system is defined by a rotatably supported gear which is acted on by a preset braking torque with the braking torque being chosen so as to be smaller than the torque of the ram when under a maximum pressing power.

Abstract: The method relates to the recovery of fine sand on floating production equipment in the form of a floating grab-bucket type excavator or floating bucket chain dredger. In this case, the dredged material is dewatered and transported to shore via floating conveyor belts. The dredged material is transferred to dewatering screening machine having a dewatering deck with a dewatering coating. Below the dewatering deck the screening machine has a blind bottom covering the entire surface area, whereby in the direction of conveyance the end zone is provided with a discharge. The discharge is directed at a hydro belt separator, which has a revolving endless conveyor belt with a washing trough as the separation bed, and an ascending part leading away from the washing trough. The running direction of the conveyor belt is in the direction of the ascent, whereby the dredged material is transferred at the discharge of the screening machine to the washing trough of the hydro belt separator.

Abstract: A monitoring device for motor-driven underwater grab bucket dredges contains a bucket gear suspended on a cable. The device ensures reliable monitoring and controlling of the operating condition of the bucket gear 4. There is at least one sensor connected to the grab bucket gear for sensing a measured value. There is a computer connected to the sensor for representing the measured value detected by the sensor.

Abstract: A device for washing out and classifying organic, clay-like and other impurities from gravel, comprising a charging chute for feeding material into a washing trough. The washing trough comprises a conveyor belt designed to move in a direction perpendicular to the direction of the flow of material and a plurality of shower devices designed to act against the direction of travel of the belt. The conveyor belt is supported by a series of support rollers and tension rollers.

Abstract: A device for classifying superfine material from continuously fed granular solids which has a charging chute feeding the material into a washing trough. The washing trough is formed by a conveyor belt, which is mounted on a machine frame. A part of the conveyor belt forms the washing trough downstream of the charging chute. Another part of the conveyor belt is arranged below the charging chute, and is elevated against the direction of flow of the charged material. The charging chute has a false bottom above the washing trough and in the material feed area. The false bottom is adjoined by a gap on the head end of the washing trough. The gap extends over the entire width of the trough. The remaining area of the charging chute is perforated. In another embodiment, a vat is arranged at the end of the washing trough and extends over the entire width and depth of the washing trough. The vat has a flow of liquid passing over it and is filled with spherical elements of different shapes, sizes and surfaces.
