Abstract:
A pulverizing apparatus for pulverizing a hard resin composition has a pulverizing mechanism having a pair of rollers arranged parallel to one another, these rollers pulverizing the hard resin composition by pressuring the hard resin composition between the rollers and a cooling device for cooling the hard resin composition during the hard resin composition being pulverized. Each of the rollers has a cylindrical shape with a hollow portion and the cooling device is configured to supply a coolant into the hollow portion of each of the rollers. The coolant flows in the hollow portion of each of the rollers in a longitudinal direction of each of the rollers. The cooling device has facilitating members respectively inserted into the hollow portions of the rollers.
