New Generation of Strand Pelletizers

Cope­ri­on Pel­letiz­ing Tech­nol­o­gy, intro­duces improved dual bear­ing strand pel­letiz­ers which have been re-engi­neered based on field expe­ri­ence and cur­rent mar­ket demands. The SP140, SP240 and SP340 mod­els in the SP series have been equipped with a vari­ety of enhanced fea­tures for easy, rapid han­dling and opti­mized pel­let qual­i­ty.  More­over, the com­pa­ny has devel­oped a new pro­pri­etary tech­nol­o­gy for cut­ting gap adjust­ment which impress­es users with increased com­fort and speed com­pared to tried and true clas­sic sys­tems. The new gen­er­a­tion of the strand pel­letiz­ers will be on dis­play for the first time at K 2019 in hall 14 at booth 14B19.

This new cut­ting gap adjust­ment (patent pend­ing) con­sti­tutes the heart of the re-engi­neered strand pel­letiz­ers. Con­ven­tion­al solu­tions like eccen­tric screws or com­pres­sion-ten­sion­ing screws present dis­ad­van­tages such as non-lin­ear move­ments, poten­tial dirt pock­ets on the prod­uct, sev­er­al set­ting steps or sub­se­quent shift­ing from addi­tion­al lock­ing mech­a­nisms. The unique new tech­ni­cal solu­tion from Cope­ri­on Pel­letiz­ing Tech­nol­o­gy offers faster and more com­fort­able adjust­ment. Fine adjust­ment is also sim­pler and more pre­cise, as it can be done by hand with­out tools. Like­wise, the inte­grat­ed spring pre-ten­sion­ing elim­i­nates the screws’ free clear­ance, marked­ly reduc­ing machine set­up times.

Optimization reduces service and downtime

Along with the more com­pact design and inte­gra­tion of the oper­a­tion pan­el into the machine, the rework­ing of the inte­ri­or space counts first and fore­most among fur­ther new devel­op­ments. The robust cut­ting tools have been installed clos­er to one anoth­er, thus enabling a short­er, unguid­ed strand length in the pel­letiz­er and the best pos­si­ble cut­ting results, espe­cial­ly with soft mate­ri­als. This new con­struc­tion results in less dead space in the inte­ri­or which, togeth­er with opti­mized edges and few­er free sur­faces, pro­vides improved clean­abil­i­ty. Fur­ther­more, the new quick change cut­ting cham­ber sys­tem real­ly impress­es users. The com­plete cut­ting area is acces­si­ble with­out tools and the cut­ting unit can be exchanged quick­ly and eas­i­ly. This quick change min­i­mizes machine ser­vic­ing times and down­times. Like­wise, Cope­ri­on Pel­letiz­ing Tech­nol­o­gy reworked the intake area; where­as this pre­vi­ous­ly used a con­i­cal con­struc­tion, today a straight intake allows strands to be opti­mal­ly side fed into the pel­letiz­er. Strands are there­fore fed direct­ly into the pel­letiz­er with­out deflec­tion. Side pan­els on the intake roller pre­vent indi­vid­ual strands from break­ing free. More­over, intake pro­ceeds with­out splits or gaps so that strand tears and bev­el are avoid­ed dur­ing intake. Addi­tion­al­ly, Cope­ri­on was able to increase the oper­at­ing width by 20 mm so that high­er through­puts are now pos­si­ble. Pel­letiz­ing in this new design also fea­tures improved sound­proof­ing. Along with the more com­pact inte­ri­or cut­ting space and the result­ing small­er sound cham­ber, all motors are now housed under the base plate and are noise insu­lat­ed there. In so doing, machine oper­a­tion at a very low noise lev­el is possible.

Pelletizing with a multitude of options, suitable for every need

These new, opti­mized strand pel­letiz­ers are avail­able now, impress­ing man­u­fac­tur­ers not only with these new devel­op­ments but with proven tech­nol­o­gy as well. Among these, for exam­ple, are a pel­let out­let chute with sound­proof cladding, a fre­quen­cy-con­trolled dri­ve, and pneu­mat­ic con­trol for feed roll pres­sure. The base­plate is mount­ed on vibra­tion-insu­lat­ing rub­ber pads; like­wise, the pel­letiz­er is installed on lock­able rollers for more flex­i­bil­i­ty. In the con­trol cab­i­net, trans­fer sig­nals are built in for remote con­trol; more­over, the pel­letiz­er is equipped with a safe­ty device (Haake sys­tem), in place of the clas­sic retard­ing spin­dle. Oper­a­tion is thus even more ergonom­i­cal and safe.

Fur­ther fea­tures are avail­able as options for Cope­ri­on pel­letiz­ers, includ­ing a high tem­per­a­ture-resis­tant upper feed roll for long ser­vice life as well as wear-pro­tect­ed or cor­ro­sion-pro­tect­ed cut­ting rotors for high­ly filled or rein­forced mate­ri­als. Increased dri­ve pow­er for high pro­cess­ing demands is like­wise avail­able as a dual dri­ve — with a dri­ven upper feed roll for improved intake. Option­al cool­ing for the feed roll and the cut­ting head to cool the entire cut­ting cham­ber ensures a longer ser­vice life. Cope­ri­on Pel­letiz­ing Tech­nol­o­gy also offers con­trol cab­i­net cli­mate con­trol for espe­cial­ly demand­ing envi­ron­men­tal conditions.
