Isitshalo esiqhubekayo sokuxuba izigubhu siwumshini wokuxuba ochwepheshe okhiqiza ingxube ye-asphalt kwimodi yesigubhu eqhubekayo, lesi sitshalo singahlukaniswa sibe izitshalo zokuxuba izigubhu ze-asphalt kanye nezitshalo zokuxuba i-asphalt ye-counter flow. Zombili lezi zimboni zenza i-hot mix asphalt emsebenzini oqhubekayo. Ukushisa okuhlanganisiwe, ukomisa kanye nokuxutshwa kwezinto zezinhlobo ezimbili zezitshalo ze-asphalt konke kwenziwa esigubhu.

Izitshalo eziqhubekayo zokuxuba izigubhu (i-drum Mix Plant kanye ne-continuous mix plant) zivame ukusetshenziswa kubunjiniyela bokwakha, amanzi namandla, ichweba, ichweba, umgwaqo onguthelawayeka, ujantshi, isikhumulo sezindiza, kanye nokwakhiwa kwebhuloho, phakathi kwezinye izinto. Inesistimu yokuphakelwa okuhlanganisiwe ebandayo, isistimu evuthayo, isistimu yokomisa, isistimu yokuxuba, iqoqo lothuli lwamanzi, uhlelo lokuhlinzeka nge-asphalt, kanye nesistimu yokulawula ugesi.



Ukufana kwezitshalo ze-asphalt zesigubhu kanye nezitshalo ze-asphalt zokugeleza kwekhawunta
Ukulayisha ama-aggregate abandayo emigqonyeni yokudla kuyisinyathelo sokuqala ekusebenzeni kwe-Asphalt Drum Mix Plant. Izinto zokusebenza ngokuvamile zineziphakeli zemigqomo ezintathu noma ezine (noma ngaphezulu), futhi izilinganiso zifakwa emigqonyeni ehlukahlukene ngokusekelwe kusayizi. Lokhu kwenzelwa ukukala amasayizi ahlanganisiwe ahlukene ngokwezidingo zephrojekthi. Igumbi ngalinye linesango eligudlukayo lokulawula ukuhamba kwezinto. Ngezansi kwemigqomo kunebhande elide lokuthutha elihambisa ama-aggregate kusikrini se-scalping.

Inqubo yokuhlola iza ngokulandelayo. Lesi sikrini esidlidlizayo esinedekhi eyodwa sisusa ama-aggregate amakhulu futhi sizigcine zingangeni esigubhu.

I-conveyor yokushaja ibalulekile enqubweni yesitshalo se-asphalt ngoba ayithuthi kuphela izinhlayiya ezibandayo ukusuka ngezansi kwesikrini ukuya esigubhu kodwa futhi ikala ama-aggregate. Lesi sidluliseli sineseli yokulayisha ehlala ijabulisa ama-aggregate futhi inikeze isignali kuphaneli yokulawula.

Isigubhu sokumisa nokuxuba siphethe imisebenzi emibili: ukomisa nokuxuba. Lesi sigubhu sijikeleza njalo, futhi ama-aggregate adluliswa ukusuka komunye umkhawulo kuya komunye ngesikhathi soguquko. Ukushisa okuvela elangabini lokushisa kusetshenziswa kuma-aggregate ukunciphisa umswakama.

Igcina ithangi likaphethiloli lesishisi sezigubhu futhi ilethe uphethiloli kumshini wokushisa izigubhu. Ngaphandle kwalokho, ingxenye eyinhloko ihlanganisa amathangi okugcina itiyela agcina, ukushisa, kanye nokumpompa itiyela elidingekayo esigubhuni sokumisa ukuze kuhlanganiswe nezihlanganisi ezishisayo. Amasilo okugcwalisa engeza okokukhetha kokugcwalisa kanye nezinto zokuhlanganisa ku-mixer.

Ubuchwepheshe bokulawula ukungcola bubalulekile kule nqubo. Basiza ekukhipheni amagesi angaba yingozi endaweni ezungezile. Umqoqi wothuli oyinhloko umqoqi wothuli owomile osebenza ngokuhambisana nomqoqi wothuli wesibili, okungaba isihlungi sesikhwama noma isikhuhla sothuli esimanzi.

I-conveyor ekhipha imithwalo iqoqa itiyela ehlanganisiwe eshisayo kusukela ngaphansi kwesigubhu bese iliyisa emotweni elindile noma esiseleni sokugcina. I-HMA igcinwa esiseleni esingakhethwa kuso kuze kufike iloli.


Umehluko wezitshalo ze-asphalt zesigubhu kanye nezitshalo ze-asphalt zokugeleza kwe-counter
1. Isigubhu sibalulekile ekusebenzeni kwe-Asphalt Drum Mix Plant. Esitshalweni sokugeleza okuhambisanayo, ama-aggregate asuka elangabini lokushisa, kanti, esitshalweni sokugeleza kwekhawunta, ama-aggregate aya ngaselangabi lomlilo. Ama-aggregate ashisayo ahlanganiswe nebitumen namaminerali ngakolunye uhlangothi lwesigubhu.

2. Ukugeleza okuhlanganisiwe esitshalweni sokugeleza okuhambisanayo kuhambisana nelangabi lomlilo. Lokhu futhi kubonisa ukuthi ama-aggregate asuka elangabini lokushisa njengoba ehamba. Ukugeleza kwama-aggregate esitshalweni sokugeleza kwekhawunta kuphambene (okuphambene) nalokho kwelangabi lokushisa, ngakho-ke ama-aggregate aya ngaselangabi lokushisa ngaphambi kokuba ahlanganiswe nebitumen namanye amaminerali. Lokhu kubonakala kuqondile, kodwa kwenza umthelela omkhulu enqubweni yazo zombili lezi zinhlobo zezixube zetiyela futhi kunomthelela ngisho nakwikhwalithi ye-HMA. Kucatshangwa ukuthi i-counter-flow mixer yonga uphethiloli omningi futhi inikeza i-HMA enkulu kunenye.

Iphaneli yokulawula kumishini yanamuhla ingeyesimanje futhi iyinkimbinkimbi. Anika amandla ukugcinwa kokwakheka okuxubile okuningana okusekelwe esidingweni sabathengi. Isitshalo singalawulwa endaweni eyodwa ngephaneli yokulawula.
