Kampani yogulitsa zida zomangira yomwe yakhala ikupereka mayankho a makina omangira kwa zaka 30.
Palibe liwiro limodzi la konkriti yosakaniza ng'oma lomwe limapereka zotsatira zabwino kwambiri pa makina onse. Makina osakaniza onyamulika amatha kugwira ntchito pafupifupi 20-25 rpm m'zitsanzo za opanga zofalitsidwa, pomwe ACI imayika kusakaniza kwabwinobwino kwa lori ndi chosakanizira pa pafupifupi 12-18 rpm . Kusiyanaku ndikofunikira chifukwa kukula kwa ng'oma, mawonekedwe a tsamba, kuchuluka kwa batch ndi mtundu wa chosakanizira zimasintha momwe konkriti imayendera mkati mwa ng'oma. Kuzungulira mwachangu sikutanthauza konkriti yabwino yokha; chosakanizira chikagwira ntchito moyenera, kuzungulira konse ndi nthawi yosakaniza zimakhala zofunikira chimodzimodzi.
Kwa makina osakaniza onyamulika, chizindikiro chodalirika kwambiri ndi kuchuluka kwa makina ogwiritsira ntchito. Marshalltown imatchula pafupifupi 20–25 rpm ya makina ake osakaniza konkire onyamulika ndipo imalimbikitsa pafupifupi mphindi imodzi yosakaniza pa gulu lililonse . Izi sizikutanthauza kuti makina onse osakaniza simenti ang'onoang'ono ayenera kusinthidwa kukhala 25 rpm yeniyeni, koma zimasonyeza kuti liwiro la ng'oma ndi nthawi yosakaniza ziyenera kuganiziridwa pamodzi m'malo mowonedwa ngati malo osiyana.
Osakaniza magalimoto amagwiritsa ntchito njira yosiyana yogwirira ntchito. ACI imanena kuti osakaniza magalimoto nthawi zambiri amagwira ntchito pafupifupi 12-18 rpm panthawi yosakaniza. Ndi njira yoyenera yolemerera, pafupifupi 70-100 drum revolutions nthawi zambiri ziyenera kupereka kusakaniza kokwanira. Ngati kusakaniza kochepetsa madzi kwawonjezeka pamalopo, ACI imalimbikitsa pafupifupi 30 revolutions zina kuti zigwiritsidwe bwino.

| Chosakaniza magalimoto paulendo | Pafupifupi 2–4 rpm | Sungani konkriti wosakaniza |
Phunziro lothandiza ndi losavuta: RPM yosakanizira konkire yonyamulika ndi RPM yosakanizira galimoto sizinthu zosinthika .
Ayi. Chosakaniza chikafika pa liwiro lomwe chinapangidwira, kungopangitsa kuti ng'oma izungulire mofulumira sikutsimikizira kuti imagwirizana bwino. Malangizo a Marshalltown ogwiritsira ntchito chosakaniza chonyamulika amaika ng'oma pa 20–25 rpm kenako n’kuganizira kwambiri kulola pafupifupi mphindi imodzi kuti gululo lisakanizike. Mwa kuyankhula kwina, makina amafunika kuyenda kokwanira komanso nthawi yokwanira; liwiro lokha silingalowe m'malo mwa nthawi yosakaniza.
Mfundo yomweyi ikupezeka mu malangizo a ACI truck-mixer. Pambuyo pa kuzungulira pafupifupi 100 pa liwiro losakaniza , ACI imalimbikitsa kuchepetsa ng'omayo kufika pa liwiro logwedezeka pansi pa 6 rpm . Paulendo, pafupifupi 2–4 rpm ndi chinthu chachizolowezi. Panthawiyo, ntchito ya ng'oma yasintha: siikufunanso kuphatikiza zosakaniza mwamphamvu, koma kuti simange konkriti yosakanikirana.
Chifukwa chake, chosakaniza si makina ochapira omwe amagwiritsidwa ntchito pozungulira. Gulu likasakanizidwa bwino, liwiro lowonjezera nthawi zambiri limapangitsa makinawo kuchita masewera olimbitsa thupi kwambiri.
Zonsezi ndizofunikira, koma ng'oma ikagwira ntchito pa RPM yolondola yosakaniza konkire , kuchitapo kanthu kosakaniza kumakhala kothandiza kwambiri. ACI imagwiritsa ntchito ma 70-100 rounds ngati njira yogwiritsira ntchito lori-mixer chifukwa gululo limafunika kukweza, kugwa ndi kupindika kokwanira kuti likhale lofanana. Izi ndizothandiza kwambiri kuposa kutchula RPM yokha chifukwa 15 rpm kwa masekondi angapo ndi 15 rpm kwa mphindi zingapo sizikupangitsa kuti kusakaniza konse kukhale kofanana.
Pa makina osakaniza onyamulika, malangizo a opanga nthawi zambiri amafotokozera lingaliro lomwelo monga nthawi yosakaniza m'malo mwa kusintha konse. Mwachitsanzo, Marshalltown imaphatikiza liwiro lake la ng'oma la 20-25 rpm ndi pafupifupi mphindi imodzi yosakaniza. Chifukwa chake, lamulo lothandiza laukadaulo ndilakuti: gwiritsani ntchito RPM yotchulidwayo kaye, kenako onetsetsani kuti gululo limalandira nthawi yokwanira kapena kusintha konse kwa ng'oma kuti likhale lofanana.
Inde. Kusakaniza kwa nthawi yayitali sikotetezeka kokha. ACI ikunena kuti kusakaniza kwambiri pambuyo posakaniza bwino kungachepetse kutsika. Ngati ogwiritsa ntchito awonjezera madzi kuti abwezeretse kutsika koyambirira, mphamvu ya konkriti ikhoza kutsika pafupifupi 8–20% pa ola limodzi , kutengera kutentha kwa konkriti ndi kuchuluka kwa kutayika kwa kutsika.
Ichi ndi chimodzi mwa zifukwa zomwe ogwiritsa ntchito sayenera kusunga gulu lonse pa liwiro lonse losakaniza chifukwa chakuti ng'oma ikhoza kupitiriza kuzunguliridwa. Konkire ikasakanikirana bwino, yankho lolondola nthawi zambiri limakhala kusunthira ku gawo lofunikira losakanikirana m'malo mowonjezera kusakaniza mwachangu. Kupangitsa ng'oma kugwira ntchito nthawi yowonjezera sikupangitsa kuti konkireyo ikwezedwe.
Zipangizo zomwe zili mkati mwa ng'oma zimasinthanso yankho. Pa konkriti yolimbikitsidwa ndi ulusi mu chosakanizira chodutsa, ACI imalimbikitsa liwiro la 10-12 rpm pamene ulusi ukuwonjezedwa. Ulusi wonse ukalowa mu chosakanizira, gululo liyenera kulandira ma rzungulo ena osachepera 40 a ng'oma , ofanana ndi mphindi 4-5 , kuti lipititse patsogolo kufalikira kwa ulusi wofanana.
Ichi ndi chikumbutso chothandiza kuti "liwiro labwino kwambiri la konkriti yosakaniza ng'oma" limadalira makina ndi zipangizo zake. Konkriti wamba, konkriti yotsika kwambiri komanso konkriti yolimbikitsidwa ndi ulusi ingafunike njira zosiyanasiyana zosakaniza ngakhale pamene chosakaniza chomwecho chikugwiritsidwa ntchito.
Kuzungulira ng'oma kumagwira ntchito kokha chifukwa masamba amkati amakweza ndikugawanso konkire. Chosakaniza chokhala ndi mainchesi osiyana a ng'oma kapena mawonekedwe a tsamba chingapangitse njira yosiyana ya zinthu pa RPM yomweyo. Ichi ndichifukwa chake kukopera liwiro kuchokera ku makina ena kumakhala koopsa ngakhale kuti zosakaniza zonse ziwiri zikuwoneka zofanana kuchokera kunja.
Kukula kwa gulu kumafunikanso. Ng'oma yodzaza imasiya malo ochepa kuti konkire inyamule, igwedezeke ndikupindika m'malo osakanikirana. Ngati chosakanizira chipanga magulu osasakanikirana bwino ngakhale RPM ili yolondola, yang'anani katundu weniweni musanasinthe pulley, liwiro la injini kapena makina oyendetsa. Liwiro lolondola la ng'oma silingapulumutse gulu lomwe limaposa mphamvu yomwe chosakaniziracho chikufuna.
Ngati ng'oma imagwira ntchito bwino ndipo tsopano ikuzungulira pang'onopang'ono kwambiri, vutoli limakhala la makina kuposa la konkriti. Yambani poyang'ana ngati ng'omayo ili pang'onopang'ono ikakhala yopanda kanthu kapena itangoyamba kunyamula. Ng'oma yopanda kanthu pang'onopang'ono imaloza ku gwero lamagetsi, lamba, pulley, bearing kapena drive system. Ng'oma yomwe imayenda bwino yopanda kanthu koma imachedwa kwambiri ikanyamula katundu ingasonyeze kukula kwakukulu kwa batch kapena kukana kwa makina kosazolowereka.
Pa makina osakaniza onyamulika, yerekezerani liwiro lenileni la ng'oma ndi mulingo wovomerezeka wa wopanga. Ngati makina omwe akuyembekezeka kugwira ntchito pafupifupi 20–25 rpm ali pansi pa chiwerengero chimenecho, fufuzani makina oyendetsa m'malo mongolola gululo kusakaniza nthawi yayitali ndikuyembekeza zabwino.
