Tchulani phula limodzi la granulation motere: feedstock, kukonzekera kusungunula kofunikira, kutulutsa mpweya, ntchito yosakaniza, kukana kusefera ndi njira yopangira ma pelletizing. Tchulani ngati chakudya ndi pellet woyera, ufa, agglomerate, otsukidwa flake kapena variable zobwezerezedwanso mtsinje. Perekani kalasi ya utomoni, mawonekedwe a mayeso a MFR, chinyezi, kuipitsidwa, zodzaza, zotulutsa zomwe mukufuna, mota, rpm, kukonza vacuum ndi zizindikiro zapano. Chophimbacho chikhoza kupangidwa mozungulira zenera lazinthu zenizeni m'malo mwa m'mimba mwake mwadzina.

Sankhani zomangira zowomba filimu motere: utomoni ndi mapangidwe, filimu yomalizidwa ndi mawonekedwe osanjikiza, ntchito ya mzere, kenako wononga geometry ndi dongosolo lapamwamba. Funsani giredi yeniyeni ya utomoni ndi kuyezetsa kosungunuka, osati “LDPE,” “LLDPE” kapena “HDPE” yokha. Jambulani chiŵerengero chophatikizika, zowonjezera, zobwezerezedwanso, zotulutsa, liwiro la screw, mota, kufa, m'lifupi mwa filimu ndi makulidwe osiyanasiyana. Pokhapokha sankhani m'mimba mwake, L / D, kuya kwa chakudya, mbiri yosungunuka, gawo la metering komanso ngati chotchinga kapena gawo losakanikirana ndiloyenera.

Yesani kuvala ngati peyala yotengera malo, osati ngati screw diameter imodzi. Chongani ma axial station kudzera m'magawo a chakudya, kuponderezana ndi metering. Pa siteshoni iliyonse, lembani wononga kuwulukira kunja kwake ndi mbiya mkati mwake munjira zingapo zamakona. Kenako muwerengere chilolezo cha diametral ndi radial padera. Fananizani mapu ndi chojambula chovomerezeka choyambirira kapena zovomerezeka zovomerezeka. Ngati muli ndi ziwalo zong'ambika zokha, lembani zotsatira ngati deta ya momwe zinthu ziliri. Osawawonetsa ngati miyeso yoyambirira.

Bwezerani wononga pokha poyezedwa mbiya yoboola, kuzungulira, mawonekedwe a pamwamba ndi kuyanjanitsa kumakhalabe koyenera wononga poto yatsopano yomwe mukufuna. Bwezerani mbali zonse ziwiri pamene mbiya yakulitsidwa, yozungulira, yotsukidwa m'deralo, yagoletsa kapena yachita dzimbiri kotero kuti screw yatsopanoyo idzayendabe ndi chilolezo chochuluka kapena chosagwirizana. Ngati mulibe miyeso yoboola, musayerekeze. Malo athu a fakitale ndi osavuta: mawu ongobwereza-okha sayenera kutengedwa ngati malingaliro aukadaulo mpaka mbiya yafufuzidwa.

Sankhani chomangira chokhazikika cha chakudya chokhazikika, chofananira cha pellet ndi kutulutsa pang'ono pomwe ntchito yosavuta ndiyofunikira kwambiri. Sankhani chotchinga chotchinga pamene mzere ukufunika kusungunuka kwathunthu ndi kutulutsa kokhazikika pamitengo yapamwamba, makamaka ya PE ndi PP. Sankhani wononga zosakaniza pamene kusungunuka-kutentha kufanana, mtundu kugawa kapena zowonjezera kubalalitsidwa ndi vuto lalikulu. Ntchito zotchinga ndi zosakanikirana sizimangokhala. Nanhaiya aluminium-pulasitiki panel single screw, mwachitsanzo, amagwiritsa ntchito chotchinga-mtundu wosakanikirana kuti athandizire kusungunuka, kufanana kwa kutentha ndi kugawa kwa mitundu ndi zoletsa moto.

Sitimayo imodzi yokha imakwera pamene zinthu zikuyenda mumzerewu zikusiya kukhazikika. Zomwe zimachitika kawirikawiri ndi monga kudyetsa kosagwirizana, kusinthasintha kwa liwiro, kutentha kwa migolo yosakhazikika, kusungunuka kosakwanira kapena kosakhazikika, kusintha kwa sikirini kapena kuletsa kufa, kuvala kwa mbiya ndi kutsika kwa liwiro. Jambulani kuthamanga kwa sungunuka, mphamvu yamagalimoto, kuthamanga kwa screw, kutentha kwa madera, kuchuluka kwa chakudya ndi liwiro lakutsika pamndandanda womwewo musanasinthe makonda. Ngati kuthamanga ndi zotuluka zikuyenda pamodzi, fufuzani njira yotuluka ndi kutuluka. Ngati ma extruder amakhazikika pomwe zinthu zikusintha, yambani ndi kufa, kuziziritsa, vacuum, kutulutsa kapena kuwinda.
