摘要： In the process for the agglomeration of slightly soluble and hydrolytically sensitive substances, a powder of the slightly soluble substance is conducted, together with at least one water-soluble binder, in free fall through a steam atmosphere at temperatures between 85.degree. C. and 105.degree. C. essentially without the action of compacting forces. In this process, the residence time in the steam atmosphere is approximately 0.5 to 10 seconds. The agglomerates formed are then dried in free fall, so that small solid bridges form from the binder liquid bridges formed at the points of contact between the primary particles. In a following integrated fluidized-bed dryer, the final drying then takes place to a water content of less than 0.5% by weight. The process is carried out in a steam jet agglomerator in which a freely falling product curtain of the pulverulent mixture to be agglomerated is impinged by steam using steam jet nozzles (5, 6). A fluidized-bed dryer (2) is connected at the lower part of the agglomerator (1) in such a manner that the agglomerated particles (4) fall directly into the fluidized bed.

摘要： Granule production is based on particle growth in a fluidized bed (4), in which the liquid starting product is sprayed into the fluidized bed and the finished granular particle is discharged from the fluidized bed (4) with classification. The classification is carried out with the aid of a classifying air flow which is divided into individual single flows (6) to each of which is assigned a zigzag classifier module (7, 17) and a spray nozzle (5) or a group of spray nozzles. The course of the classifying process is such that the granular particles which are too small and have not yet reached the desired diameter are thrown back into the fluidized bed (4) by a return shaft (9, 18) seated on each of the zigzag classifier modules (7, 17) in parallel or radial zones without cross-mixing, in which the relatively small particles impinge at a relatively large distance from the return shaft (9, 18) and the large particles, which have already grown close to the discharge size, impinge at a relatively small distance. The process is carried out with the aid of a fluidized bed granulator, to the inlet plate (2) of which is connected a zigzag classifier, subdivided in a modular manner, in which each zigzag classifier module (7, 17) is provided with a return shaft (9, 18) at the point where it joins the inlet plate (2, 16). In addition, at least one spray nozzle (5) at the inlet plate (2, 16) is allocated to each zigzag classifier module (7, 17).

摘要： The zigzag classifier has a classifying space provided with air inlets which is subdivided into zigzag-shaped ducts, which are connected in parallel with respect to the flow, the lengths of which are greater than their widths. In this way a classifier package is formed with a plurality of small duct cross-sections. This design principle permits substantially lower overall heights for the same number of bends.
