A pulsating vibration air generation apparatus capable of sharply and quickly controlling air flow in turning on and off operation, thereby generating a pulsating vibration air with sharp and hardly attenuated peak and valley, and capable of operation without occurrence of so much mechanical vibration. The pulsating vibration air generation apparatus is comprised of a main body having a tubular hollow space Rwith which two air communication ports are associated, and a rotary body situated for rotation in the tubular hollow space Rand which has a peripheral side surface Sso as to slide on the inner surface Sforming the tubular hollow space R

Pulsating vibration air generation apparatus

Pulsating vibration air generation apparatus comprising a cylindrical casing having an air supply port connected with an air source and a wave transmission port provided at the circumferential surface thereof, and a drum type rotary valve constructed rotatably in the casing, wherein the air supply port is located where a circumferential surface of the rotary valve is positioned when the rotary valve is contained in the casing, the wave transmission port is located apart from where the circumferential surface of the rotary valve is positioned when the rotary valve is contained in the casing, the drum type rotary valve is comprised of a rotary support shaft at a center axis, one end of the rotary valve is opened, another end of the rotary valve is closed, at least one ventilation window is provided at the circumferential surface of the rotary valve, the rotary valve is contained in the casing in such a manner that the open end of the rotary valve faces to the wave transmission port of the casing, and the at least one ventilation window provided at the circumferential surface of the rotary valve is designed to intermittently meet the air supply port according to rotation of the valve when a rotary drive apparatus is connected with the rotary support shaft and the rotary drive apparatus is driven.

Pulsating vibration air generation means

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.
