Imbere EPS Amasaro mbisi, habaye gaze ihindagurika yitwa pentane. Nyuma yo gukaza, pentane atangira kwagura kugirango ingano ya Bead nayo imeze neza, ibi byitwa kwaguka. Amasaro ya ePS ntashobora gukoreshwa muguhagarika cyangwa gupakira ibicuruzwa mu buryo butaziguye, amasaro yose agomba kwagurwa mbere noneho kora ibindi bicuruzwa. Ubucucike bwibicuruzwa bwemejwe mugihe cya mbere, bityo kugenzura ubucucike bikorwa muri prexpander.

EPS Pre - Kwagura hamwe no kwagura kabiri bimaze kwaguka ePS ibikoresho bisabwa, imashini ikora muburyo bubi hamwe nogusohora ibikoresho byagutse. Imashini irashobora gukora ubucucike bwa kabiri.
EPS Pre - Kwagura Byuzuye hamwe na Convelaceur ya Screw, Kwamamaza kwambere kwa Kwamamaza, Urugereko rwa Kwagura, Gutuza

EPS Pre - Kwagura hamwe no kwaguka kwa kabiri ni ubwoko bwimashini ya ePS ikorana nubuyobozi bwamanike. EPS Ibikoresho fatizo bibanje kuzura muri convelator ya swansion to operation. Munsi yumugezi ni screw, kwimura ibikoresho kuva kumenagura kugera ku cyumba cyo kwaguka. Mugihe cyo guhunika, gukomera ni ugutera guhora mu bushobozi buke ndetse no kwambara. Ibikoresho bibisi byimukira mucyumba ubudahwema, kandi nyuma yo guhuriza hamwe, kugeza kurwego ruhoraho, kugeza kurwego rwibikoresho bigera kurwego rumwe rwo gusohora icyambu cyo gutangiza icyambu, noneho ibikoresho bizahita bisohoka. Isumbuye ifungura ni, igihe kirekire ibikoresho biguma muri barrile, bityo ubucucike ni; Hasi yo gufungura ni ukuvuga, kugabanya ibikoresho biguma muri barrile, niko hejuru cyane. Igenzura ryumubare uhoraho - Imashini yo Kwagura iraryoroshye cyane. Niba igitutu cya steam gihamye cyangwa kidafite uruhare runini mubucucike bwo kwaguka. Kubwibyo, ibikomeza mbere - Imashini yo Kwagura ifite ibikoresho byubuyapani bigabanya valve. Kugirango dukore igitutu cya Steam muri Machine gihamye, dukoresha screw kugirango tugaburire ibikoresho kumuvuduko umwe, hamwe nu mwobomyamba n'amasasu hamwe nibisambano bimwe bishoboka.
