Abstract: An agitator apparatus for agitating pellets of raw material of synthetic resins includes an agitation vessel for receiving pellets and coloring agents and removably housed in a supporting frame. An agitator is mounted elevatably on the supporting frame for entering into and withdrawing from the vessel. The agitator has a plurality of agitating legs and agitating blades which are mounted to respective lower ends of the agitating legs. The agitation vessel is provided in the center bottom thereof with an upright guiding pillar to which a stationary blade is fixed and is provided in the inner peripheral wall thereof with a plurality of mixing blades for agitating the pellets together with coloring agents in the agitation vessel to accomplish uniform coloring of the pellets.

Abstract: A cooled pellet making machine includes a rotary cutter and a fixed blade mounted on a fixed support table in opposition to the rotary cutter for cutting a strand into pellets. Each of the fixed support table and the fixed blade are provided with a communication chamber having an inflow port formed in one end and an outflow port formed in the other end. The communication chamber of the fixed blade is connected with the communication chamber of the fixed support table. Cooling water may be circulated through the communication chamber to eliminate heat from being generated on the fixed blade. Therefore, the strand may be cut in a cooled condition by means of the rotary cutter, to produce pellets of uniform size.

Abstract: A pellet making machine used in a pellet producing process has a rotary cutter mounted to the outer periphery of a hollow rotary shaft. A fixed blade is disposed opposite to the rotary cutter, and a pellet exhaust chute is disposed below the rotary cutter and slopes downwardly therefrom. The rotary cutter is provided with an interior cooling chamber and the hollow rotary shaft is provided with water inflow holes and exhaust holes communicating with the cooling chamber of the rotary cutter. A water supply tube extends into the hollow rotary shaft and is supported within the shaft by a partition wall, which also forms a water supply passage communicating with the water inflow holes of the hollow rotary shaft and a water exhaust passage communicating with the water exhaust holes of the hollow rotary shaft.
