Abstract: The invention relates to an air jet sieve device having a housing, at least one sieve for insertion in the housing, a sieve deck and chamber located below the sieve, a slotted nozzle beneath the sieve deck, a drive for the slotted nozzle, an air inlet to the slotted nozzle, an air outlet through the housing and out of the chamber located beneath the sieve deck, and a control unit to control operation of the device. The invention also relates to a method that permits not only detection of the sieving progress during a sieving process but also provides a criterion to permit establishing the sieving time. This is achieved by equipping the sieving machine with a measuring sensor through which the particles in the air outlet flow are detected triboelectrically and which are correlated with the sieving progress to permit establishing the sieving time.

Abstract: The invention concerns an impact mill suitable for installation in a container. To this end, the container must have an opening, e.g. a manhole with flange. The mill is designed as a complete and independent module without a separate mill housing, all functional components are mounted on a plate which is flanged onto the manhole.

Abstract: A system for process-technological machines such as mills and classifiers having an enclosed design with no rotary unions between the ambient air and system interior. This system is particularly useful for CIP and SIP operation modes or glove-box operations. The mills or classifiers include an encapsulation that seals the components of the magnetic bearing spindle drive against the working zone of the shaft in the magnetic bearing spindle housing. The magnetic bearing spindle drive is designed such that the shaft can be removed to facilitate simpler and easier component exchange as well as thorough cleaning.

Abstract: The invention concerns a process-technological system for the laboratory that has a frame which can be equipped with a variety of different processing machines and which can be used for both wet and dry processing. The system frame is equipped with an adapter to which the various machines can be connected, and the requisite media such as air and water needed to operate the machines are supplied through the adapter.

Abstract: Fluidized-bed opposed jet mills, configured as separator mills, and provided with easy accessibility so that the interior space can be easily cleaned with little effort. The separator wheel is formed together with the bearing unit and the actuator unit as one component, which is detachably attached to the grinding container and can be moved relative to the grinding container by kinematic devices in such a manner that the separator wheel can be removed from the grinding container upward through the discharge outlet for finely ground material, while the discharge device for the finely ground material remains connected to the grinding container. In this manner, the separator mill can be easily assembled and disassembled by the user and the separator mill becomes easily accessible for thorough cleaning. This is particularly advantageous when the material to be ground is changed frequently, as is the case in the pharmaceutical and chemical fields.

Abstract: This invention relates to an air classifier for the separation of granular material into three fractions, whereby each individual fraction is very precisely separated in a single housing. The classifier incorporates motor-driven separator/classifying wheels each of which is provided with a tangential separating-air supply at the level of the respective wheel, a fixed guide vane ring positioned at a radial distance from the circumference of the respective separating wheel, and at least one bulk-product feeder system as well as discharge provisions for fine, intermediate and coarse material, respectively. The wheels are provided with a closed cover disk at their respective first axial end and with fine and, respectively, medium fraction discharge port at their respective second axial end. The closed cover disks of the wheels form a free-flow gap in the space between the two stages of the classifier.

Abstract: A vertical-axis air classifier having a central product feed, a drive shaft, a tangential classifying air supply inlet located on a level with the rotor, a stationary guide vane ring arranged at a radial distance around the periphery of the rotor, a deflector-wheel rotor with one-sided bearing as well as a housing with fine material and coarse material discharge. The drive shaft, an annular-shaped fines discharge chamber arranged coaxially to the drive shaft, an annular-shaped coarse material discharge chamber arranged coaxially to the drive shaft and the bearing for the rotor are arranged on the same side and beneath the rotor to permit ease of cleaning and dismantling.

Abstract: The invention concerns the design of classifying wheel made of a waterproof sintered material with vanes arranged in a ring that run parallel to the rotational axis and that are positioned between the hub-bearing circular disc and an annular cover disc, whereby the flow of the classifying air through the vanes is contrary to the centrifugal direction of the classifying wheel. Described is a classifying wheel design which permits manufacture of such a classifying wheel in an economical manner with a high degree of manufacturing accuracy even if the classifying wheel has an outside diameter in excess of 250 mm and which ensures the required degree of fracture resistance for any standard sintered material. This is achieved in that the classifying wheel is made up of simple ring elements joined together by a self-sintering filler, e.g. an adhesive, introduced into the gaps between the ring elements.
