Choyamba, kasitomala amayenera kutanthauzira mawonekedwe azinthu zobwezerezedwanso ndi mtundu wake, komanso kuyesa mphamvu yobwezeretsanso (kg/hr).
Ili ndiye gawo lofunikira pakusankha makina obwezeretsanso.Makasitomala ena atsopano nthawi zonse amakhala ndi kusamvetsetsanamakina obwezeretsanso pulasitiki, yomwe imatha kukonzanso mitundu yonse ya pulasitiki.Kwenikweni, pulasitiki yamitundu yosiyanasiyana imakhala ndi mawonekedwe ndi mawonekedwe osiyanasiyana.Kutentha kwawo komwe amapempha kusungunuka ndi kuthamanga kwa extruding ndizosiyana kwambiri.The wamba pulasitiki extruder akhoza kukonzanso ndi granulate/pellets mapulasitiki athu tsiku ndi tsiku.Zomwe zimafala kwambiri ndi polypropylene ndi polyethylene, monga filimu yapulasitiki, zikwama zoluka, zikwama, beseni, migolo, ndi zofunikira zatsiku ndi tsiku.Kwa mapulasitiki apadera monga mapulasitiki a Engineering ABS, zipangizo za botolo la PET, ndi zina zotero zimafuna extruder yapadera ya pulasitiki.
Chachiwiri, chitsanzo cha extruder chimasankha kukula kwa wononga m'mimba mwake ndi mphamvu yobwezeretsanso.Posankha chitsanzo extruder, kasitomala akhoza osati kulabadira chitsanzo extruder, komanso nkhawa makina processing mphamvu.Nthawi zambiri, mphamvu zoperekedwa ndi supplier zimayimira mphamvu yotulutsa.Gulu lobwezeretsa pulasitiki la PURUI loperekedwa ndi extruder limaphatikizapo ML model extruder, SJ model extruder ndi TSSK model twin screw extruder, yomwe inkagwiritsidwa ntchito ngati filimu yapulasitiki kapena thumba la granulating/pelletizing, kukonzanso pulasitiki kolimba komanso kusinthidwa kwa pulasitiki, flake ya botolo la PET, kuphatikiza pulasitiki ndi batch master. .
Chachitatu, kasitomala amafunikiranso kukumbutsa othandizira omwe ali ndi madzi obwezerezedwanso (zonyansa) ndi kuchuluka kosindikizidwa.PURUI yoperekedwa ndi screw extruder imodzi yokha imatha kukonza zinthu zoyera kapena zotsukidwa mkati mwa 5% yamadzi.Zinthu zobwezerezedwanso zauve zikadutsa 5% mpaka 8%, kasitomala asankhe magawo awiri obwezeretsanso extruder yobwezeretsanso zinthu.Pankhani yosindikizidwa, ogulitsa amafunika kulimbikitsa makina otsekemera ndi makina osefa.
Chachinayi, pokhala ndi malingaliro osiyanasiyana ogulitsa, ogwiritsa ntchito amatha kusankha ma granulators apulasitiki (extruder) okhala ndi magawo apamwamba aukadaulo ndi mitengo yololera kudzera mu kufananiza koyima kapena kopingasa."Longitudinal" amatanthauza kuti zigawo zazikulu zaukadaulo za granulator ya pulasitiki (extruder) ziyenera kukwaniritsa miyezo yamakampani ndikuwunikiridwa molingana ndi miyezo yamakampani."Horizontal" ndi kuyerekeza kutengera magawo aukadaulo a granulators apulasitiki ofanana (extruder) kumayiko ndi kunja.
Chachisanu, malinga ndi bajeti, ogwiritsa ntchito amazungulira omwe angakhale ogulitsa.Kupyolera mu tsatanetsatane wamakina okambitsirana ndi luso laopanga opanga kusanthula, ukadaulo wokhwima, kugwiritsa ntchito makina ndi ntchito pambuyo pake, ndi zina zambiri.
Chachisanu ndi chimodzi, mutatsimikiza mndandanda womaliza wa ogulitsa, makasitomala amatha kupita kukafufuza wopanga granulator(extruder) yofananira ndi mtengo wa granulator(extruder).Makamaka kufufuza kukula kwa wopanga, mphamvu zopangira, ndi mbiri ya makasitomala omwe amagwiritsa ntchito zida.Musaope ulendo wautali.Chinsinsi chogulira zida ndikugula makina otsika mtengo okhala ndi ukadaulo wamphamvu komanso ntchito yogulitsa pambuyo pake, kuti pasakhale nkhawa panthawi yogwiritsa ntchito mtsogolo.Mukangogula zida zotsika mtengo kapena zapafupi, magwiridwe antchito ndi mtundu wa zida za chipangizocho sizikhala zokhazikika ndipo zogwiritsidwa ntchito zidzadyedwa.
