Ngaphakathi ubuhlalu be-eps obuluhlaza, kukhona igesi elishayayo elibizwa ngePentane. Ngemuva kokuntshontsha, i-pentane iqala ukwanda ukuze usayizi wobubi futhi uyakhula, lokhu kubizwa ngokuthi kuyakhula. Ubuhlalu be-EPS obuluhlaza ngeke busetshenziselwe ukwenza amabhlogo noma imikhiqizo yokupakisha ngqo, bonke ubuhlalu budinga ukwandiswa kuqala bese wenza eminye imikhiqizo. Ubuningi bomkhiqizo bunqunywa ngesikhathi sokuphamba kwe-Preexpanding, ngakho-ke ukulawulwa kwe-density kwenziwa ePreexpander.

I-EPS Pre - I-Expander ene-yowesibili iyasebenza ukwandisa impahla evuthayo ye-EPS ku-density edingekayo, umshini usebenza ngendlela eqhubekayo yokuthatha impahla evuthiwe kanye nokukhipha imali enwetshiwe.
I-Eps Pre - Expander Qeda nge-Screw Conveyor, Isithasiselo sokuqala kanye nesiBili, igumbi lokunwebisa, umdlwane wombhede ofuwuwe

I-EPS Pre - Expander nge-Expond yokwenyuka ngohlobo lomshini we-EPS osebenza ngokulawulwa kwemishini. Izinto ezisetshenziswayo ze-EPS zigcwaliswa okokuqala kusuka ku-screwning conveyor ku-indawo yokunweba. Ngezansi komthwalo isikulufa, ukuhambisa impahla kusuka ku-Lower kuya egumbini lokunweba. Ngesikhathi sokuntshontsha, ukushaqeka okukhulayo kuqhubekela njalo ukwenza ubukhulu bezinto ezibonakalayo noma umfaniswano. Izinto ezibonakalayo ezivuthiwe ziye eChamber ngokuqhubekayo, futhi ngemuva kokuntshontsha, izinga lezinto ezibonakalayo liyaqhubeka, kuze kube sezingeni lezinto ezibonakalayo lifika ezingeni elifanayo lokukhipha imbobo yokuvula, khona-ke impahla izophuma ngokuzenzakalelayo. Ukuvulwa okuphezulu kokukhuculwa kungukuvulwa kokukhuphuka, okukude okuqukethwe kuhlala emgqonyeni, ngakho-ke kwehlisa ubuntukube; Ukwehliswa kokuphuma kokuphuma, okufushane kokuqukethwe kuhlala emgqonyeni, ngakho-ke ukukhuphuka kwabantu kuphakeme. Ukulawulwa kokuqhubeka kwangaphambili - Ukunwebeka umshini kulula kakhulu. Ukuthi ingcindezi ye-Steam iyazinza noma cha inethonya elikhulu ekunciphiseni. Ngakho-ke, umshini wethu oqhubekayo wokuqhubeka - Ukwanda Komshini uhlome nge-Valve YesiJapan enciphisa i-valve. Ukuze wenze umfutho we-Steam emshinini uzinzile, sisebenzisa isikulufa ukondla okuqukethwe ngejubane elifanayo, futhi umusi womfaniswano nokuphakelwa komfaniswano kufana ngangokunokwenzeka.
