    • A production method and system for granulating powdered material wherein powdered material is fluidized by applying heated pulsating vibration air, and the fluidized powdered material is suspended up and down at a regular cycle by means of heated pulsating vibration air, the aggregated material is compressed by further vibration of pulsating vibration air, whereby the aggregated powdered material is efficiently made into granulated material with high density and rather small specific volume without causing projection on the surface and without being made porous. The production system is comprised of a granulation tank for storing powdered material to be granulated, the granulation tank having a supply port for introducing heated air at the bottom thereof, a discharge port for discharging the introduced heated air at the top thereof, and a fluidization bed provided above the supply port for receiving the powdered material. A spray apparatus for spraying a binder solution provided in the granulation tank for aggregating the powdered material stored in the granulation tank for growing the material is provided. An air source connected to the supply port of the granulation tank via a conduit pipe; heating apparatus interposed in the conduit pipe for heating the air generated from the air source; and a pulsating vibration air generation means interposed in the conduit pipe for converting the air generated from the air source to pulsating vibration air.
    • 通过施加加热的脉动振动空气使粉末材料流化的制粉方法和制造方法,流化粉末材料通过加热的脉动振动空气以规律的周期上下悬浮,聚集的材料进一步压缩 脉动振动空气的振动,由此将聚集的粉末材料有效地制成具有高密度和相当小的比体积的粒状材料,而不会在表面上产生突起而不被制成多孔。 该生产系统包括用于储存待造粒的粉末材料的造粒罐,该造粒罐具有用于在其底部引入加热空气的供给口,用于在其顶部排出引入的加热空气的排出口, 提供在供应口上方的用于接收粉末材料的床。 提供一种喷雾装置,用于喷射设置在造粒罐中的粘合剂溶液,用于聚集存储在造粒罐中用于生长材料的粉末材料。 通过管道连接到造粒罐的供应口的空气源; 插入导管中的加热装置,用于加热从空气源产生的空气; 以及插入在导管中的脉动振动空气产生装置,用于将从空气源产生的空气转换成脉动的振动空气。
