Upfu hwetalc hunogadzirwa ne talcchigayo chekukuya muchina. Talc ndeimwe yezvicherwa. Yakavigwa pasi pevhu neserpentinite ine asbestos, saka inowanzova neasbestos muchimiro chayo chechisikigo. Mikana yeasbestos muupfu hwetalc hwekurapa yagara ichikakavadzana zvikuru mumakore achangopfuura. Dambudziko rekutanga rinotarisana netalc powder mukurapa idambudziko rekuchengetedza. Iye zvino, talc powder yekurapa ine maitiro akakosha ekugadzira kuti ive nechokwadi chekuchengetedzwa kwekurapa. Semugadziri wehunyanzvi weupfu hwetalc hweRaymond chigayo, HCMilling (Guilin Hongcheng) ichakurukura nemi nezvekugadzirwa kwehupfu hwetalc hwekurapa uye kushandiswa kweupfu hwetalc hweRaymond chigayo.

Ungaziva sei kana hupfu hwetalc huri hwekurapa? Hupfu hwetalc hwekurapa hune mhedzisiro yakawanda, senge kubvisa kupisa, kuburitsa hunyoro, kubatsira maburi, kuporesa kupisa nenyota, kuita weti isina kunaka, manyoka, manyoka, gonorrhea, jaundice, kuzvimba, kubuda ropa, beriberiberi, uye ganda rakanyorova. Zvinhu zvinonyungudika muacid chiratidzo chakakosha chehupfu hwetalc hwekurapa. Ruzivo rwakakodzera runoratidza kuti zvinhu zvinonyungudika muacid yehupfu hwakawanda hwetalc hwekurapa hunotengeswa pamusika hunodarika 2.0% yehuya hwakatarwa neChinese Pharmacopoeia. Chinhu chakakosha ndechekuona kuti hupfu hwetalc hwekurapa hauna asbestos. Kazhinji, kugadzirira hupfu hwetalc hwekurapa netalc sezvinhu zvisina kugadzirwa kunonyanya kuitwa kuburikidza nekusanganiswa kwemaitiro.

Maitiro ekugadzira upfu hwetalc yekurapa: chekutanga, talc ore mbishi inogadziriswa kuita coarse talc powder ne chigayo chekukuya chetalc, ine hutete hwemamesh angangoita 325; Zvadaro, kupatsanurwa kwemagineti uye kubviswa kwetsvina. Hupfu hwetalc hwakacheneswa hunowedzerwa nemvura kugadzirira slurry, uye huwandu hwakakodzera hwesodium silicate hunowedzerwa. Mushure mekusanganisa, hupfu hwetalc hunotumirwa muwed magnetic separator nekumhanya kwakati, uye tsvina inobviswa pasi pesimba remagnetic field; Zvadaro inocheneswa neacid. Sanganisa hupfu hwetalc hwakacheneswa nemagineti nehuwandu hwakakodzera hwemvura, sanganisa slurry nehydrochloric acid ne20% mass concentration ye10-30% crude talc powder, kurunga zvakaenzana kusvika pasina mabubbles anogadzirwa pamusoro pemvura, sefa, geza nemvura kusvika washing solution yasara, wobva waita flotation refine; Wedzera huwandu hwakakodzera hwemvura kuhupfu hwetalc hwakacheneswa neacid kugadzirira pulp, wedzera pulp nemusanganiswa weflotation ne 0.03-0.2% mass ratio yehupfu hwetalc hwakacheneswa mudhiramu rekusanganisa pulp kuti usanganise, wobva waisa pulp mutangi reflotation kuti flotation ifambe; Pakupedzisira, zvigadzirwa zvakanatswa zvakagezwa, zvakasefetwa uye zvakaomeswa, uye pakupedzisira hupfu hwetalc hwakagadzirwa nemishonga hwakawanikwa.

HCMilling (Guilin Hongcheng) inyanzvi yekupa chigayo chekukuya chetalc. Nhevedzano yedu yeHC uyeHCQ series talcChigayo cheRaymond zvave zvichishandiswa zvakanyanya mumusika wekugadzira talc. Kuti zvizadzise zvinodiwa pakugadzira talc yekurapa, mapaipi esimbi asingatsvi anogona kugadziriswa kuti ave nechokwadi chekuti chigadzirwa chapera chachena. Kana uchida kugadzira upfu hwetalc yekurapa uye uchida kutengatalcchigayo chekukuyamuchina, ndapota taura nesu kuti uzive ruzivo rwemuchina wachotalc Raymondchigayomuchina.
