Abstract
A plastics granulating apparatus includes a cutter holder having cutter knives driven to rotate along a die surface of a die and a housing provided with a cutter drive shaft for driving the cutter holder to rotate in a manner so that plastics particles are obtained by cutting resin extruded from the die with the cutter knives, wherein a sleeve is axially movably provided in the housing so as to coaxially rotatably hold the cutter drive shaft, and a pressure medium is supplied into space chambers formed between the sleeve and the housing so that the cutter drive shaft moves axially with axial movement of the sleeve.
