This little pelletizer is just packed with features.  You know why?  Because people kept bringing materials into our lab that were, to be kind, difficult!  It seemed that R&D people never brought us nice production quality materials.  No.  No.  Instead, they were absolutely intent on bringing stuff  they couldn't run (Perhaps stuff best described as lumpy, bumpy, brittle, sticky, or slick.  On Mondays, invariably, it was all of the above!).  As a result, this pelletizer incorporates features to make your life easier.  Main Features:  Both nips are driven.  Most pelletizers drive only one nip and the other roll just idles along and that doesn't help pull anything.  If you have a technician you want to punish, you can always have him disconnect the drive on this pelletizer to the second nip roll.  Probably, he has nothing better to do than manually feed strands  into a nip with an idle attitude. Cantilevered design.  How long will it take you lab tech to clean the nip rolls or the cutter if he can't get at them?  (No problem.  He's on the clock and needs the overtime.)  Nip rolls and cutters wear.  Then they need replacement.  Choose this user friendly design where you turn a self aligning collar to remove and install new parts.  This is much easier, if you think about it, than designs that put the wearing parts between two plates so that you have to take the whole pelletizer apart because the nip roll wore out.   Designed in flexibility. In the field, change the pellet length, line speeds, or add the second drive.  You can even change the  size of the pellet collection bucket by moving the board (shown under the bucket) up or taking it out.   The pelletizer shown here has one drive for the nip roll and one for the cutter to vary the pellet length on demand. Adjust the air pressure on the nips--don't be stuck with springs like most pelletizers.
