<p>A granulated substance compression molding apparatus that realizes simplification of pin push mechanism leading to reduction of apparatus cost, increase of the number of molding apertures and enhancement of granulated substance productivity. The compression molding apparatus is one for production of granulated substance through compression molding of a raw material by means of a pair of press rolls with their both end portions supported, wherein among the pair of press rolls, at least one thereof is hollow, the press roll in its outer circumferential portion provided with a given number of molding apertures, in which compression pins for insertion in the molding apertures are slidably fitted, and in which there are fitted push means for pushing of the compression pins along the axial direction of the interior of the hollow press roll.</p> |
