Abstract

PURPOSE:To uniformly knead a ceramics powder and a binder, by coaxially arranging the leading end part of the nozzle provided in a die and the opening part of the die and connecting the material supply port of a kneading cylinder to said opening part. CONSTITUTION:The extruded material from a die 4 is supplied between a kneading cylinder 18 and a screw 21 to be transferred to the leading end side of the cylinder 18 and strongly kneaded between Dulmage 20 and the spiral blade 19 of the screw 21 and subsequently extruded to the space between the Dulmage 20 and the kneading cylinder 18 to be uniformly kneaded by the Dulmage 20. A molten binder 25A and a ceramics powder 26 are converted to a homogenous clayey mixture 28 which is, in turn, supplied to the leading end part of the kneading cylinder 18 and continuously extruded from the extrusion orifice 22 of a plate 23 while the extrudate is cut by a reciprocally moving cutter 24 to be formed into ceramics pellets 29 which are, in turn, fallen in a container 30.

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a ceramic pellet manufacturing apparatus.

(Prior art and its problems) Ceramic pellets have traditionally been produced mainly through a bunching process in which ceramic powder and binder are weighed to a certain ratio, placed in a container, stirred there for a certain period of time, and then taken out.

However, in this conventional method, the ceramic powder and binder, which were placed separately, were simply stirred in a container, so it was not easy to uniformly disperse the fine ceramic powder in the highly viscous binder. Moreover, it took time and effort to transfer the ceramic pellet material from the container to the pelletizer.

Therefore, this was one of the causes of lowering the productivity of ceramic pellets. In addition, there were also problems in that the ceramic powder was scattered during stirring, and a portion remained in the container without being kneaded with the binder, causing it to scatter when discharged from the container.

Therefore, conventional methods have been considered in which ceramic powder and binder are supplied separately to an extrusion cylinder and kneaded continuously, but in this conventional method, ceramic powder and binder are continuously and accurately measured to maintain a fixed ratio. It was difficult to do so. Furthermore, there is a lack of reliability in uniformly kneading fine ceramic powders into a highly viscous binder.
