摘要:
A granulation process wherein a liquid is sprayed into a prilling tower (1) by means of a rotating prilling bucket (15) having a perforated side wall (15a), and the liquid jets exiting said perforated side wall are subjected to a vibrating action according to the axial direction (A-A) of the prilling tower (1), while the remaining liquid mass inside the bucket is kept substantially free from said vibrating action. A suitable apparatus is also disclosed, wherein the peripheral side wall (15a) of the prilling bucket (15) is connected to vibration imparting means and has a flexible connection with the frame (15b, 15c) of the bucket.
摘要:
A method of preparing a permanently-charged electret toner, including discharging a solution or dispersion comprising a resin and a colorant through a nozzle vibrating at a constant frequency to form a droplet; applying a direct potential to an electrode facing the nozzle to positively or negatively charge the droplet by an induction phenomenon to form a charged droplet; and drying and solidifying the charged droplet to be permanently charged.
摘要:
Apparatus for the granulation of a predetermined substance provided in fluid, semi-fluid and similar state, comprising a prilling tower having a prilling bucket (15) associated to a driving shaft (14). The prilling bucket is mounted in a sliding way on the driving shaft. A device (27) for applying vibration is directly associated with said bucket.
摘要:
A new system and method for making agglomerates of chopped glass fiber strand segments is disclosed as are the agglomerates produced. The agglomerates, made by feeding wet chopped fiber strand segments into a wave chamber having a vibrating curved surface that produces a wave-like flow pattern in the segments and agglomerates, have a substantially higher bulk density and greatly improved flow characteristics than conventional chopped strand reinforcements. The wet agglomerates are usually dried in any conventional dryer.
摘要:
The invention is directed to a process for the production of crystalline energetic materials having improved stability and/or decreased sensitivity by crystallisation of the energetic materials with ultrasonic vibration having a frequency of between 10 and 100 kHz.
摘要:
Ein Verfahren zum Granulieren von flüssigen oder pastösen Stoffen, wie Lebensmitteln, durch Frosten zeichnet sich dadurch aus, daß ein impulsierender Strahl aus diesen Stoffen in ein Kühlmittelbad in einem Gehäuse eingeleitet wird, das Gehäuse in Vibrationen versetzt wird, und der durch die Vibrationen in Granulatstücke auseinandergebrochene Stoff nach einer vorbestimmten Verweilzeit aus dem Gehäuse ausgetragen wird.
