Zipangizo zophwanyira ndi maziko a mafakitale a migodi, zomangamanga, kupanga zinthu zonse, ndi zobwezeretsanso zinyalala zomanga, zomwe zimayang'anira kuchepetsa zipangizo zazikulu monga miyala, miyala ndi zinyalala za konkire kukhala zazikulu zomwe zingagwiritsidwe ntchito pa ntchito zomangamanga, zomangamanga ndi mafakitale. Ndi mitundu yosiyanasiyana ya zophwanyira zomwe zikupezeka pamsika, iliyonse yopangidwira ntchito zinazake ndi mawonekedwe azinthu, kumvetsetsa mfundo zawo zogwirira ntchito, zochitika zogwiritsira ntchito, ndi njira zosankhira ndikofunikira kwambiri kwa akatswiri amakampani kuti azitha kuyendetsa bwino ntchito, kuchepetsa ndalama ndikuwonetsetsa kuti polojekiti ikuyenda bwino. Nkhaniyi ikupereka chidule chatsatanetsatane cha mitundu yodziwika bwino ya zophwanyira, njira zawo zazikulu zogwirira ntchito, ndi malangizo othandiza posankha zasayansi, kutengera machitidwe amakampani ndi malingaliro aukadaulo ovomerezeka.
Ma crushers onse amatha kugawidwa m'magulu awiri akuluakulu kutengera mfundo zawo zazikulu zophwanya: ma crushers okakamiza ndi ma crushers okakamiza. Ma crushers okakamiza amaswa zinthu pozikanikiza pakati pa malo awiri olimba mpaka zitasweka, pomwe ma crushers okakamiza amagwiritsa ntchito ma impacts othamanga kwambiri kuti aswe zinthuzo kukhala tinthu tating'onoting'ono. Gulu lililonse lili ndi mitundu ingapo ya ma crushers wamba, iliyonse ili ndi mapangidwe apadera komanso mawonekedwe ogwirira ntchito ogwirizana ndi mikhalidwe yosiyanasiyana yogwirira ntchito.
Zipangizo zophwanyira nsagwada ndi zophwanyira nsagwada zomwe zimagwiritsidwa ntchito kwambiri komanso zimayimira zophwanyira nsagwada. Kapangidwe kake kamakhala ndi mbale yokhazikika ya nsagwada ndi mbale yosunthika ya nsagwada; mbale yosunthika ya nsagwada imayenda mozungulira ndi mozungulira motsutsana ndi yokhazikika pansi pa shaft yosasunthika ndi mbale yosinthira, ndikupanga mphamvu yofinya yomwe imaphwanya zinthu zazikulu zomwe zimalowetsedwa m'chipindamo. Zipangizo zophwanyira nsagwada zimagawidwa m'mitundu yosinthira nsagwada imodzi ndi iwiri, ndipo mitundu yosinthira nsagwada imodzi imagwiritsidwa ntchito kwambiri masiku ano chifukwa cha mphamvu zawo zapamwamba poyerekeza ndi zina zosinthira nsagwada ziwiri za kukula komweko. Amachita bwino kwambiri pogwira zinthu zazikulu, zolimba monga granite ndi basalt, zomwe zimapangitsa kuti zikhale zoyenera kwambiri pophwanya nsagwada yoyamba m'migodi ndi m'mabwinja. Kapangidwe kawo kosavuta, kukonza kosavuta komanso kuthekera kolandira kukula kwakukulu kwa chakudya (mpaka mamita 1.5) kwawapanga kukhala zida zofunika kwambiri mumakampani ophwanya nsagwada.
Zipangizo zophwanyira gyratory ndi mtundu wina wa makina ophwanyira compression, omwe amagwiritsidwa ntchito makamaka pophwanyira koyamba mu ntchito zazikulu zamigodi. Mofanana ndi makina ophwanyira ntchafu, ali ndi cone yakunja yokhazikika (concave) ndi cone yozungulira yamkati (mantle) yoyikidwa pa swing shaft. Zipangizo zimaphwanyidwa mosalekeza pakati pa ma cones awiriwa pamene mantle imaphwanyira, ndipo dongosolo losinthira kutulutsa kwa hydraulic limalola kuwongolera nthawi yeniyeni kwa kukula kwa zinthu zomaliza. Poyerekeza ndi makina ophwanyira ntchafu, makina ophwanyira gyratory ali ndi mphamvu yayikulu (mpaka 1200 t/h ndi kupitirira apo) chifukwa cha njira yawo yophwanyira mosalekeza komanso kutsegula kwakukulu kozungulira, zomwe zimapangitsa kuti zikhale zoyenera migodi yokhala ndi mphamvu zambiri komwe zinthu zambiri zopangira ziyenera kukonzedwa bwino. Komabe, kapangidwe kawo kovuta komanso ndalama zambiri zogulira ndalama zimachepetsa kugwiritsa ntchito kwawo m'mapulojekiti ang'onoang'ono ndi apakatikati.
Ma cone crushers, omwenso ndi a compression crushers, amagwiritsidwa ntchito makamaka pa magawo achiwiri, atatu komanso abwino kwambiri ophwanyira. Mofanana ndi ma gyratory crushers, amasiyana kukula ndi momwe amagwiritsidwira ntchito—cone crushers ndi ochepa kwambiri ndipo amapangidwa kuti aphwanyire bwino. Njira yophwanyira imadalira kuzungulira kwa eccentric kwa mantle, komwe kumapangitsa mphamvu yofinya pakati pa mantle ndi concave, kuswa zinthu kukhala tinthu tofanana. Ubwino waukulu wa cone crushers ndi momwe zimaphwanyira pakati pa tinthu, pomwe tinthu timaphwanyirana panthawi ya ndondomekoyi, kuchepetsa kuwonongeka kwa mbale za liner ndikukweza mtundu wa malonda. Ndi oyenera kwambiri pokonza zinthu zolimba komanso zokwawa, ndipo njira yawo yosinthira kutulutsa kwa hydraulic imalola kusintha kosalekeza pansi pa katundu, ndikuwonjezera kusinthasintha kwa ntchito. Kuti zigwire bwino ntchito, cone crushers amalimbikitsidwa kuti azigwira ntchito ndi chakudya cha chipinda chonse, chomwe chingapezeke pogwiritsa ntchito silos ndi zida zowunikira mulingo.
Zipangizo zophwanyira mphamvu, kutengera mfundo yophwanyira mphamvu, ndi zosinthika ndipo zingagwiritsidwe ntchito m'magawo oyambira, achiwiri kapena achitatu ophwanyira mphamvu. Zimagawidwa m'mitundu iwiri ikuluikulu: zophwanyira mphamvu za shaft (HSIC) ndi zophwanyira mphamvu za shaft (VSIC). Zipangizo zophwanyira mphamvu za shaft (Horizontal shaft impact crushers) zimakhala ndi rotor yozungulira yothamanga kwambiri yokhala ndi mipiringidzo yophulika; zipangizo zimakankhidwa ndi mipiringidzo yophulika ndikuponyedwa pa mbale zophwanyira mphamvu m'chipinda chophwanyira, kenako zimaphwanyidwanso ndi kugundana pakati pa tinthu tating'onoting'ono, ndikupanga zinthu zooneka ngati cubical zokhala ndi gradation yabwino. Ndizoyenera kukonza zinthu zolimba zapakatikati monga miyala yamchere ndi zinyalala zomangira. Zipangizo zophwanyira mphamvu za shaft, zomwe nthawi zambiri zimatchedwa "mapompo a miyala", zimafulumizitsa zinthu kudzera mu rotor yozungulira ndikuzitulutsa mwachangu kwambiri, kuziphwanya ndi kugunda ndi khoma la chipinda ndi kugundana pakati pa tinthu tating'onoting'ono. Zimagwiritsidwa ntchito makamaka pagawo lomaliza lophwanyira mphamvu, makamaka pamene ma aggregates apamwamba kwambiri akufunika pa ntchito zomanga.
Kusankha chotsukira choyenera kumafuna kuganizira mozama zinthu zingapo, kuphatikizapo makhalidwe a zinthu, zofunikira pakupanga, ndalama zogwirira ntchito komanso kutsatira malamulo a chilengedwe. Choyamba, zinthu monga kuuma, chinyezi ndi kukula kwa tinthu toyambirira ndizofunikira kwambiri: zipangizo zolimba kwambiri (monga granite) ndizoyenera zotsukira nsagwada kapena zotsukira za cone, pomwe zipangizo zolimba zapakatikati zimatha kukonzedwa ndi zotsukira za impact. Zipangizo zokhala ndi chinyezi chambiri zimatha kutsekeka, zomwe zimafuna zotsukira zokhala ndi mapangidwe apadera monga zotchingira grate. Kachiwiri, mphamvu yopanga ndi zofunikira pa khalidwe la chinthu zimatsimikiza mtundu wa chotsukira ndi kasinthidwe: mapulojekiti akuluakulu omwe ali ndi zosowa zambiri angafunike kuphatikiza zotsukira nsagwada ndi zotsukira za cone, pomwe mapulojekiti ang'onoang'ono kapena oyenda akhoza kugwiritsa ntchito malo otsukira oyenda. Pomaliza, kugwiritsa ntchito bwino ndalama kuyenera kuyesedwa, kuphatikiza ndalama zoyambira, kugwiritsa ntchito mphamvu, ndalama zosamalira komanso kusintha kwa zinthu zomwe zawonongeka.
Pomaliza, kumvetsetsa mitundu yosiyanasiyana ya ma crushers, mfundo zawo zogwirira ntchito komanso momwe amagwiritsidwira ntchito ndikofunikira popanga zisankho zodziwika bwino mumakampani ophwanyira. Kaya ndi crusher yolimba kwambiri yophwanyira koyamba, crusher yolimba kwambiri ya migodi ikuluikulu, crusher yogwira ntchito bwino ya cone yophwanyira bwino, kapena crusher yosinthasintha ya zinthu za cubical, mtundu uliwonse umagwira ntchito yapadera pakukonza njira yophwanyira. Potsatira malangizo osankha asayansi ndikuphatikiza chidziwitso cha chiphunzitso ndi machitidwe omwe alipo, akatswiri amakampani amatha kusankha crusher yoyenera kwambiri, kukonza magwiridwe antchito, kuchepetsa ndalama ndikulimbikitsa chitukuko chokhazikika cha mafakitale amigodi ndi zomangamanga.
