摘要： A polymer cutter with a rotary cutting head in which the cutting edges are on the circumferential periphery of the head is described. The knife blades on the rotary head have a knife angle (as defined) of about 40° to about 60°. The apparatus is especially useful for cutting hard and/or brittle thermoplastics and may be used for preparing polymer granules or pellets.
