Abstract: Provided are a granulating device die, a granulating device cutter blade holder, a granulating device cutter blade unit, a resin-cutting device, and a granulating device, in all of which an increase in size is suppressed even when the processing amount is increased. The die (10) includes a bottom surface (10B), an upper surface (10A) having a radius smaller than a radius of the bottom surface (10B), a side surface (10C) that connects an outermost peripheral portion of the bottom surface (10B) and an outermost peripheral portion of the upper surface (10A), and a plurality of die holes (11) that discharge a resin raw material, the die holes being defined in the side surface (10C).

Abstract: This invention is to improve the reaction efficiency of a peroxide introduced into a cylinder compared with conventional art. In the peroxide reaction method and peroxide reaction device using an extruder according to this invention, in which a peroxide and a raw material such as a synthetic resin, a natural resin, and an elastomer are introduced into a cylinder of the extruder, wherein the raw material and the peroxide are reacted with each other in the cylinder, the raw material is introduced from a raw material supply hopper, the peroxide is introduced from a downstream side of the raw material supply hopper, and the temperature of the raw material in a peroxide introduction portion is adjusted to a temperature lower than the one-minute half-life temperature of the peroxide.
