Hajoale, screw extruder e le 'ngoe ke eona e sebelisoang ka ho fetesisa, e loketseng ts'ebetso ea extrusion ea lisebelisoa tse akaretsang. Twin screw extruder e na le tlase e hlahisoang ke likhohlano, ho kuta ka mokhoa o ts'oanang oa thepa, boholo bo fetisang screw, molumo o batlang o tsitsitse oa extrusion, nako e telele ea ho lula ha thepa ka moqomong, le junifomo mixi ng. SJSZ series conical twin-screw extruder e na le litšobotsi tsa extrusion e qobelloang, boleng bo phahameng, ho ikamahanya le maemo ka bophara, bophelo bo bolelele, tekanyo e tlaase ea ho kuta, ho senyeha ho thata ha thepa, ts'ebetso e ntle ea ho kopanya le polasetiki, ho bōpa ka ho toba lisebelisoa tsa phofo, joalo-joalo, ka mocheso o itekanetseng. taolo, Vacuum exhaust le lisebelisoa tse ling.
Lilemong tsa morao tjena, batho ba entse lipatlisiso tse ngata tsa theory le liteko ka screw, 'me ho na le mefuta e ka bang lekholo ea li-screw ho fihlela joale,' me tse tloaelehileng ke mofuta oa karohano, mofuta oa ho kuta, mofuta oa thibelo, mofuta oa shunt le mofuta o entsoeng ka masenke. .
