PROBLEM TO BE SOLVED: To provide a compression molding device which enables a reduction in device cost and an increase in the number of molded holes, and improvement of productivity of granulated material by simplifying a pin extrusion mechanism. SOLUTION: The compression molding device compression molds raw material by a pair of press rolls whose both ends are supported to produce a granulated material. At least one of a pair of the press rolls is formed in a hollow shape. The outer periphery of the press roll has the prescribed number of the molding holes, and compression pins, which are each inserted into each molding hole and are slidably installed in the press roll. An extrusion mean for extruding the compression pins is axially installed inside the hollow press roll. COPYRIGHT: (C)2008,JPO&INPIT
