Uri kunetseka nemvura yakawandisa mune underflow uye yakasimba mukupfachukira? Iwe unoda kukwidziridza iko thickener mashandiro kuburikidza nekubvisa yakadzokororwa density kuyerwa uye kukanganisa kwevanhu? Vazhinji vashandisi vekupedzisira vanotarisana nematambudziko akafanana muindasitiri yekugadzira zvicherwa kuchengetedza mvura uye kuunganidza zvinhu zvakakosha zvekugadzirisa. Chaiyo-nguva density mita inoshanda zvine pundutso mukuzadzisa izvi zvinangwa.
Chinyorwa chinotevera chinotarisa kutsanangura zvinangwa uye mabhenefiti ekudzora density panzvimbo dzakasiyana dzematangi ekukora. Ngatitangei nekupfupisa sumo yekukora, ichiteverwa nezvikonzero zvishanu zvekuyera density mukuparadzanisa.
Chii Chinoita Basa reKukora?
Iko kukora kunosanganisira kupatsanurwa kwemusanganiswa wakasimba-mumvura kune dense underflow uye kuyerera kwakajeka mune yakajairika. Iyo yekutanga inosanganisira yakasimba particles uye iyo yekupedzisira inobvisa tsvina zvakanyanya sezvinobvira. Nzira yekuparadzanisa ndiyo mhedzisiro yegiravhiti. Zvese zvimedu muhukuru hwakasiyana uye densities zvinoumba zvidimbu zvakasiyana kuburikidza netangi.
Maitiro ekukora anoitika mune sedimentation tangi mune zvicherwa kugadzirisa kwekuparadzanisa concentrates uye miswe.
Zvinodiwa Kuyera Mapoinzi muKukora
Online liquid density metreszvinodiwa kuti optimize kushanda thickeners. Semuenzaniso, mapoinzi ekuisa anosanganisira kudyisa, kuyerera, kufashukira uye mukati meiyo thickener tank. Mumamiriro ezvinhu ari pamusoro, aya masensa anogona kutorwa seayoslurry density mitakanasludge density mita. Ivo zvakare vanobatsira mukuvandudza otomatiki kudzora kwemadhiraivha, pombi uye nekuita dosing yemaflocculants.
Zvikonzero zvekuyera Density
Zvikonzero zvekuyera density zvinogona kusiyana chimwe nechimwe. Mamiriro mashanu anotevera anoratidza kukosha kwekutarisa density yekuvandudza maindasitiri.
Nhamba 1 Kudzoreredza Mvura
Mvura inoonekwa seimwe yezvinhu zvakakosha muindasitiri yezvicherwa nezvicherwa. Naizvozvo, kudzoreredza mvura kana kushandisazve mvura kunochengetedza mutengo wekukora zvakanyanya. Kukura kudiki kwe1-2% mu underflow density inoreva kuwanda kwemvura inodiwa kumisheni yekushandisa. Kuwedzera kwedensity kunoshanda kuvimbisa kusimba mumadhamu anopinza, anogona kudonha kana paine mvura yakawandisa inopombwa kumadhamu.
Nhamba 2 Mineral Recovery
Mune concentrate thickeners, chikafu chacho chinowanzobva kune flotation circuit. Flotation inosanganisira kupatsanura zvidimbu kuburikidza negiravhiti. Mune mamwe mazwi, avo vane mabhubhu akabatanidzwa anokwira kumusoro uye anobviswa, nepo mamwe anoramba ari muchikamu chemvura. Kana maitiro aya aitika muhupfu hwechigadzirwa, furo rinogona kutakura zvinhu zvakaomesesa mukufashukira.
Aya maoriki akakosha uye, kana asina kudzoserwa, anogona kuderedza huwandu hwese hwekudzoreredza hwesimbi yakadzika. Pamusoro pezvo, zvakaonda mukufashukira zvinogona kutungamira kumitengo yakakwira reagent, kukuvadzwa kwemapombi nemavharuvhu, uye nekuwedzera mari yekugadzirisa, senge yekuchenesa matangi emvura kana zvinyoro zvawanda ipapo.
Zvingangoita makumi mapfumbamwe kubva muzana zvezvakaoma zvakarasika mukufashukira zvinozodzoserwa muzvikamu zvinozoitika (semuenzaniso, mumatangi nemadhamu). Zvisinei, iyo 10% yakasara, iyo inomiririra kukosha kwehupfumi, inorasika zvachose. Kuderedza kurasikirwa kwezvakaoma mukupfachukira kunofanirwa kuve kwekutanga. Kuisa mari mumatekinoroji ekudzora tekinoroji kunogona kuwedzera mitengo yekudzoreredza uye kuunza kukurumidza kudzoka pakudyara.
Kushandiswa kweLonnmeterdensity metresuyeflow metersmukuyerera kwepasi kunogonesa kurinani kutarisisa kwekuita thickener. Kuonekwa kwenguva chaiyo kwezvakaoma mukufashukira kunogonekawo ne density kana solids metres. Izvo zviridzwa '4-20mA masaini anogona kubatanidzwa mune yekudzora sisitimu yeakananga maitiro optimization.
3 Kushanda Flocculant Kushandisa
Flocculants inoshanda mukuvandudza sedimentation kushanda zvakanaka, kureva makemikari anofambisa zvimedu muzvinwiwa kuti zviungane. Iyo dosing ye flocculants inotarisa mutengo wekutonga pamusoro pe reagent uye kushanda zvakanaka. Iyo density mita inobvumira chaiyo uye yakavimbika density kudzora kune iyo thickener feed. Chinangwa ndechekuwana iyo yepamusoro inogoneka solids percentage nehuremu mune feed slurry uchiri kubvumidza yemahara particle kugadzirisa. Kana iyo feed slurry density ichipfuura chinangwa, imwe nzira yedoro inofanirwa kuwedzerwa, uye yakawanda yekusanganisa simba inogona kudiwa kuti ive nechokwadi chekudya chakaringana kusanganiswa zvakanaka.
Chaiyo-nguva density kuyerwa kweiyo feed slurry uchishandisa inline density mita yakakosha pakudzora maitiro. Izvi zvinogonesa kushandiswa kwakanaka kwe flocculant uye inogonesa maitiro ekusanganisa, ichichengeta iyo thickener ichishanda mukati meiyo yainotarirwa huwandu.
4 Kukurumidza Kuonekwa kweFlocculation Matambudziko
Vashandi vanoyedza kuchengetedza mamiriro akatsiga muhukobvu, vachiwana mafashama akajekeswa ane zvinyoro zvidiki uye dense underflow ine ishoma mvura. Nekudaro, mamiriro ekuita anogona kuchinja nekufamba kwenguva, zvichizotungamira mukusagadzikana kugadzikana, kuderedzwa kwemvura inoyerera, uye yakakwira solids mukufashukira. Idzi nyaya dzinogona kubva kumatambudziko ekuyerera, mweya kana furo mutangi, kana kuwanda kwakanyanya kwezvakaoma mukudya.
Zviridzwa uye otomatiki zvinogona kubatsira vashandisi kuchengetedza kutonga nekuona nyaya dzakadai munguva chaiyo. Kupfuura zviyero zvemukati, tank-based instrumentation senge ultrasonic bed level probes inogona kupa yakakosha nzwisiso. Aya ma "diver" probes anofamba achikwira nekudzika mukati metangi, achinyora mazinga ematope, nzvimbo dzekugadzirisa, uye kujekesa kufashukira. Zviyero zvepamubhedha zvinonyanya kubatsira kune flocculation control strategy, kuve nechokwadi chekuita kunoenderana.
Slurry Density Meter (SDM)
Iyo Slurry Density Meter (SDM) ndeye eco-inoshamwaridzika imwe kune yechinyakare nyukireya density metres. Yakakurumidza kuwana mukurumbira, nemazana ekuisa pasi rese. Iyo SDM inopa yakaringana uye yakavimbika density zviyero, zvichiita kuti ive mhinduro yakanaka kune yemazuva ano mineral processing plant.
Kuyera density kunoita basa rakakosha mukuvandudza kukora uye inoshanda seyakakosha kuita chiratidzo chekudzora maitiro. Nekutora matekinoroji ekuyera epamberi uye maitiro ekudzora maitiro, vashandisi vanogona kukwidziridza kuita kwakasimba, kuwedzera mitengo yekudzoreredza, uye kuderedza mitengo yekushandisa.
