MaCrushers ese anogona kuiswa mumapoka maviri makuru zvichienderana nepfungwa dzawo dzekupwanya: maCrushers ekudzvanya nemaCrushers ekupwanya. MaCrushers ekupwanya anopwanya zvinhu nekuzviisa pakati penzvimbo mbiri dzakaoma kusvika dzatyoka, nepo maCrushers ekupwanya achishandisa maCrushers ekumhanya kukuru kupwanya zvinhu kuita zvidimbu zvidiki. Chikamu chimwe nechimwe chine mhando dzakasiyana dzemaCrushers, chimwe nechimwe chine magadzirirwo akasiyana uye hunhu hwekushanda hwakagadzirirwa mamiriro akasiyana ekushanda.
Zvikweshe zvejaw crushers ndizvo zvinonyanya kushandiswa uye zvinomiririra zvikweshe zve compression. Maumbirwo azvo ane jira rakagadzika uye jira rejaw rinofambiswa; jira rejaw crusher rinofambiswa rinofamba richidzokera shure richipesana nerinogadzika pasi pe eccentric shaft uye toggle plate, zvichigadzira simba rekudzvanya rinopwanya zvinhu zvikuru zvinopinzwa mukamuri. Zvikweshe zvejaw crushers zvakakamurwa kuita mhando dze single-toggle uye double-toggle, uye mamodheru e single-toggle ari kushandiswa zvakanyanya mumazuva ano nekuda kwekugona kwazvo kwepamusoro zvichienzaniswa ne double-toggle counterparts dzine saizi imwe chete. Dzinobudirira pakubata zvinhu zvikuru, zvakaoma zvakaita se granite ne basalt, zvichiita kuti zvive zvakanaka pamatanho ekutanga ekupwanya mumigodhi nemagori. Maumbirwo adzo ari nyore, kugadzirisa kuri nyore uye kugona kugamuchira saizi huru dzekudya (kusvika mamita 1.5) zvakaita kuti dzive michina inokosha muindasitiri yekupwanya.
Ma gyratory crushers ndeimwe mhando ye compression crusher, inonyanya kushandiswa pakupwanya kwekutanga mumabasa makuru ekuchera. Zvakafanana ne jaw crushers, dzine fixed outer cone (concave) uye rotating inner cone (mantle) yakaiswa pa swing shaft. Zvinhu zvinopwanywa nguva dzose pakati pema cones maviri sezvo mantle ichipwanyika, uye hydraulic discharge adjustment system inobvumira kudzora kwenguva chaiyo kwekupedzisira kwechigadzirwa. Zvichienzaniswa ne jaw crushers, gyratory crushers dzine kugona kwepamusoro (kusvika 1200 t/h zvichikwira) nekuda kwe continuous crushing mechanism yavo uye denderedzwa discharge open yakakura, zvichiita kuti dzikodzere migodhi ine simba guru uko huwandu hwakawanda hwezvinhu zvisina kugadzirwa hunofanirwa kugadziriswa nemazvo. Zvisinei, chimiro chadzo chakaoma uye mari yakawanda yekudyara inoderedza kushandiswa kwadzo mumapurojekiti madiki nepakati.
Makone crushers, ariwo e compression crushers, anonyanya kushandiswa pamatanho ekupwanya echipiri, matatu uye akanaka kwazvo. Zvakafanana nemakone crushers ane gyratory, akasiyana muhukuru uye mamiriro ekushandiswa—makone crushers akaomesesa uye akagadzirirwa kupwanya zvakapfava. Maitiro ekupwanya anoenderana nekutenderera kwe eccentric kwe mantle, izvo zvinogadzira simba rekudzvanya pakati pe mantle ne concave, zvichipwanya zvinhu kuita zvidimbu zvakafanana. Chinhu chikuru che cone crushers ndechekupwanya pakati pezvikamu, apo zvidimbu zvinopwanyana panguva yekuita, zvichideredza kupera kwema liner plates uye kuvandudza mhando yechigadzirwa. Akanyanya kukodzera kugadzirisa zvinhu zvakaoma uye zvinokwesha, uye hydraulic discharge adjustment system yavo inobvumira kugadzirisa nguva dzose pasi pemutoro, zvichivandudza kuchinjika kwekushanda. Kuti zviwedzere kushanda, ma kone crushers anokurudzirwa kushanda ne full-chamber feeding, izvo zvinogona kuwanikwa kuburikidza nekushandisa silos uye level monitoring devices.
Zvishandiso zve "impact crushers", zvichibva papfungwa yekupwanya kwe "impact crush", zvinogona kushandiswa zvakasiyana-siyana uye zvinogona kushandiswa muzvikamu zvekupwanya zvekutanga, zvechipiri kana zvechitatu. Zvakakamurwa kuita mhando mbiri huru: zvishandiso zve "horizontal shaft impact crushers" (HSIC) uye zvishandiso zve "vertical shaft impact crushers" (VSIC). Zvishandiso zve "horizontal shaft impact crushers" zvine "high-speed rotating rotor" zvine "blow bars"; zvinhu zvinorohwa ne "blow bars" uye zvinokandwa pa "impact plates" mu "crush chamber", zvobva zvapwanywa nekusangana pakati pezvikamu, zvichigadzira zvigadzirwa zvakaita se "cubical" zvine gradation yakanaka. Zvakakodzera kugadzirisa zvinhu zvakaoma zvepakati senge limestone nemarara ekuvaka. Zvishandiso zve "vertical shaft impact crushers", zvinowanzonzi "stone pumps", zvinokurumidzisa zvinhu kuburikidza ne "rotor" inotenderera uye zvinozviburitsa nekukurumidza, zvichizvipwanya ne "impact" ne "chamber wall" uye "inter-particle collision". Zvinonyanya kushandiswa padanho rekupedzisira rekupwanya, kunyanya kana ma "cubic aggregates" emhando yepamusoro achidiwa kumapurojekiti ekuvaka.
Kusarudza crusher yakakodzera kunoda kutariswa kwakazara kwezvinhu zvakawanda, kusanganisira hunhu hwezvinhu, zvinodiwa pakugadzira, mari yekushanda uye kutevedzera nharaunda. Chekutanga, hunhu hwezvinhu zvakaita sekuomarara, hunyoro uye saizi yekutanga yezvikamu zvakakosha: zvinhu zvekuomarara zvakanyanya (semuenzaniso, granite) zvakakodzera kune vanopwanya shaya kana vanopwanya makoni, nepo zvinhu zvepakati nepakati zvinogona kugadziriswa nevanopwanya shaya. Zvinhu zvine hunyoro hwakawanda zvinowanzovharika, zvichida macrusher ane magadzirirwo akakosha akadai sema grate screens. Chechipiri, kugona kwekugadzira uye zvinodiwa zvemhando yezvigadzirwa zvinosarudza rudzi rwecrusher uye magadzirirwo: mapurojekiti makuru ane zvinodiwa zvekugona kukuru anogona kuda musanganiswa wevanopwanya shaya nemacone, nepo mapurojekiti madiki kana ekufambisa anogona kushandisa nzvimbo dzekupwanya dzinofamba. Chekupedzisira, kushanda zvakanaka kwemari kunofanirwa kuongororwa, kusanganisira mari yekutanga, kushandiswa kwesimba, mari yekugadzirisa uye kutsiva zvikamu zvekusakara.
Mukupedzisa, kunzwisisa mhando dzakasiyana dzemacrusher, misimboti yadzo yekushanda uye mamiriro ekushandiswa kwakakosha pakuita sarudzo dzakagadzirwa neruzivo muindasitiri yekupwanya. Ingave iri crusher yakasimba yekupwanya kwekutanga, crusher ine simba guru yemigodhi mikuru, crusher inoshanda zvakanaka yekupwanya zvakanaka, kana crusher ine simba yakawanda yezvigadzirwa zve cubic, mhando yega yega ine basa rakasiyana mukuvandudza maitiro ekupwanya. Nekutevera nhungamiro dzesainzi yekusarudza uye kubatanidza ruzivo rwedzidziso nemaitiro ari panzvimbo, nyanzvi dzeindasitiri dzinogona kusarudza crusher yakakodzera, kuvandudza mashandiro, kuderedza mari uye kukurudzira budiriro inoenderera mberi yeindasitiri yemigodhi nekuvaka.
