Abstract: A screening tool includes at least a first screen lining which is coupled to a metal coupling element to which an ultrasonic transducer is connected which is connected by electrical lines to an ultrasonic generator. The screening tool includes a metal work plate which has a connection region and at least one first transfer region with first transfer openings, which first transfer region forms the first screen lining through which particles of the process material which are larger than the transfer openings can pass, from particles of the process material smaller than the transfer openings, wherein the coupling element is a curved or straight rod having a first end piece welded to the connection region and a second end piece mechanically connected to the ultrasonic transducer. The screening device includes one or more such screening tools and a control unit by means of which the ultrasonic generator is controllable.

Abstract: A device, which serves to separate particles of a bulk material, which is deliverable at an input location and is removable processed in different or at least approximately unitary particle sizes at an output location, includes at least one separating element, which has a metal separating plate with through-openings provided therein, which separating element can be provided with ultrasonic energy and for this purpose is connected to an ultrasonic transducer and which is held by a holding device. The holding device is a mounting shaft, which is held at one end or at both ends fixedly or movably, in particular rotatably and/or axially displaceable, and which at one end or at both ends is connected to an ultrasonic transducer, by means of which ultrasonic energy is couplable via the mounting shaft into the separating element, which is designed to be dimensionally stable.

Abstract: The transport device, which serves for the transport of pulverous or granular process material, includes an open or in itself closed transport frame made of metal for transporting process material, is held by a support device and is connected to an ultrasonic device having an ultrasonic generator, an ultrasonic transducer connected to the ultrasonic generator and a coupling rod connected to the ultrasonic transducer and having front and rear end pieces. A flat distributor body made of metal has upper, lower, rear sides and peripherally at least one connection side. The rear end piece of the coupling rod is connected to the ultrasonic transducer. The front end piece of the coupling rod is welded to the rear, upper, or lower side of the distributor body. The at least one connection side of the distributor body is integrally connected with or welded to the at least one transport frame.

Abstract: The sieving device includes a support device, which holds a sieve, which has at least one sieve lining that is held by a sieve frame, which is connected to a drive device. The drive device, which is controllable by a control device by means of a control program, includes at least three actuators, which are connected each on one side via a first swivel joint to the support device and which are connected each on another side via second swivel joint to the sieve frame, so that the sieve is held solely by the actuators and is displaceable within an operating volume and optionally rotatable.
