Claims

[Claims for Utility Model Registration] 1. A drive shaft 5 is provided concentrically inside the cylindrical screen 1, a rotating frame 6.7 is fixed to the drive shaft 5,
A roller 9 is rotatably supported on the rotating frame 6.7 at a position close to the screen 1, and based on the rotational drive of the drive shaft 5, the roller 9 is driven to revolve through the rotating frame 6.7 and also rotates freely. By doing so, the granulated material introduced into the screen 1 is transferred from the space 11 in front of the revolution of the roller 9 to the screen 1.
In an extrusion type granulator configured to extrude granules out of a large number of granulation holes, roller 9
An extrusion molding granulator characterized in that the rotation axis G of the drive shaft 5 is inclined on a plane S parallel to and separated from the axis Z of the drive shaft 5. 2. The outer shape of the roller 9 is made into a barrel shape or a shape approximating the shape of a barrel so that the outer peripheral surface 9A of the roller 9 is inscribed in the screen inner peripheral surface 1A in almost uniform line contact over the entire length of the roller 9. An extrusion molding granulator according to claim 1 of the utility model registration claim. 3. According to claim 1 or 2 of the utility model registration claim, in which the total number of rollers 9 is an even number of 4 or more, and the inclination directions of the roller shafts 7 are opposite to each other. The described extrusion granulator. 4 Anti-slip groove 9a on the outer peripheral surface 9A of the roller 9
The extrusion molding type granulator according to any one of claims 1 to 3, which is a utility model registered, and is formed to be inclined with respect to the rotation axis G of the roller 9.
