Ma'adinan sarrafa ma'adinai shine rabuwar ma'adanai da aka yi niyya daga sauran ma'adanai da ke kewaye da shi. Wannan tsari ya kasu kashi biyu. Dangane da ma'adinai, ana iya aiwatar da shi ta hanyoyi daban-daban. A ST Boats & Technology (STET), mun sadaukar da mu don nemo abin da ya dace da muhalli, mai rahusa, da sauri bayani ga hankula ma'adinai aiki. Shi ya sa muka kirkiro STET triboelectric SEPARATOR. Tare da wannan kayan aikin rabuwar ma'adinai, sami samfur mafi inganci a cikin ɗan lokaci kaɗan, a farashi mai rahusa.
Aikin sarrafa ma'adinai shine tsarin cire ma'adanai daga ƙasa. Rarraba su zuwa sassa masu amfani da marasa amfani. Misali, idan kuna kokarin fitar da taman ƙarfe daga ƙasa, za ku fitar da adadin wasu ma'adanai da shi. Domin raba wadannan sauran ma'adanai daga baƙin ƙarfe da kuke ƙoƙarin cirewa, ajiya zai buƙaci ta hanyar sarrafa ma'adinai. Wannan tsari ya kasu kashi biyu manyan matakai - shiri da rabuwa.
Akwai manyan matakai guda biyu wajen sarrafa ma'adinai. Ana iya yin kowane mataki ta hanyoyi da yawa. An zaɓi takamaiman kayan aikin ma'adinai da dabaru dangane da ma'adinan da kuke nema don cirewa da abubuwan sinadaran su.
Domin yadda ya kamata a raba ma'adinan da aka zaɓa daga ma'adinai, dole ne a shirya. Manufar shirya ma'adinai shine don sauƙaƙe rabuwa ga ma'adanai daban-daban. Kowane ma'adinan dole ne ya kasance a ɗan lokaci ko cikakke ya bayyana don tsarin rabuwa ya yi aiki. Don fallasa ma'adanai, Dole ne a murkushe ma'adinan ma'adinan ko kuma a nitse cikin ƙananan guda.
Ana sanya manyan tama a cikin injin murƙushewa ko injin niƙa kuma a juye su zuwa ƙananan guda. Ana mayar da waɗannan guda a cikin injin murkushewa ko injin niƙa har sai an sami takamaiman girman da kuke buƙata don rabuwa. Ana iya amfani da ƙwanƙwasa da maƙala da yawa don cimma wannan girman girman. Kayan aikin sarrafa ma'adinai domin wannan ya hada da jaw da gyratory crushers, mazugi crushers, tasiri crushers, nadi crushers, da injin niƙa.
Rarraba ma'adanai shine inda aka raba ma'adanai masu amfani da ma'adanai marasa amfani (kuma aka sani da gangue material). Dangane da nau'in ma'adinai da kuke nema don cirewa, za ku iya amfani da dabarun rabuwa daban-daban, ko haɗin fasaha, gami da rabuwar rigar ko bushewar rabuwa.
Rabuwar rigar ya haɗa da amfani da ruwa don raba ma'adanai. Babban nau'ikan rarrabuwar rigar shine rabuwar flotation da rigar maganadisu. Rabuwar ruwa yana amfani da sinadarai na ma'adinai da ake so. Ta zabar wani takamaiman sinadaran reagents wanda ke amsa ma'adinan, ma'adinan yana manne da martani - raba shi da sauran kayan. Tare da rigar maganadisu rabuwa, An yi niyya ma'adinan bisa ga mitar maganadisu. A cikin ganga da ruwa, ana amfani da ƙarfi mai ƙarfi ko ƙananan ƙarfi don raba ma'adanai. Tare da rigar rabuwa, dole ne a bushe samfurin ƙarshe ta hanyar dewatering.
Rashin bushewa baya amfani da ruwa kuma ya fi dacewa da muhalli. Babban nau'ikan rabewar bushewa shine rabuwar nauyi, bushewar maganadisu, da electrostatic rabuwa. Rarraba nauyi yana amfani da nau'ikan jan hankali daban-daban akan ma'adanai don kai hari ga ma'adinan zabi. Dry Magnetic Sepparation yana amfani da tsari iri ɗaya da rigar magnetic rabuwa amma ba tare da amfani da ruwa ba. Rabuwar Electrostatic yana amfani da cajin ma'adinan don raba shi da wasu.
Triboelectric rabuwa yana daya daga cikin mafi kyawun hanyoyin da za a raba ma'adanai daga juna. A cikin mai raba wutar lantarki, ana cajin barbashi, rabu da caji, kuma ya rabu da nauyi. Duk waɗannan ana yin su da injin guda ɗaya. An raba ma'adanai da sauri da sauƙi. Sakamakon shine samfurin bushe gaba ɗaya wanda ke shirye don pelletization. Bugu da kari, rarrabuwa na triboelectric yana ba da damar ƙananan saka hannun jari / farashin aiki kuma yana haifar da tasiri kaɗan akan yanayin.
Neman sauri, hanya mafi sauƙi don sarrafa ma'adanai? Yi amfani da na'urar rabuwa ta lantarki ta STET. Muna ba da kayan aikin rarraba ma'adinai na zamani ga abokan cinikinmu da kuma taimaka musu. Kuna son ƙarin koyo? Tuntube mu a yau!
