石英砂中有黑點怎么辦，讓石英砂色選機來幫您

    石(shi)(shi)(shi)(shi)英(ying)(ying)砂(sha)(sha)(sha)里面如果(guo)含(han)有黃點(dian)、黑點(dian)這樣的(de)(de)(de)(de)(de)瑕(xia)疵，在市場(chang)上(shang)的(de)(de)(de)(de)(de)銷(xiao)售價(jia)格可(ke)(ke)能比品相較好的(de)(de)(de)(de)(de)石(shi)(shi)(shi)(shi)英(ying)(ying)砂(sha)(sha)(sha)來說銷(xiao)售價(jia)格可(ke)(ke)能就比較低(di)了。目前全國各地對(dui)于(yu)都存在著石(shi)(shi)(shi)(shi)英(ying)(ying)砂(sha)(sha)(sha)色選(xuan)的(de)(de)(de)(de)(de)需(xu)求(qiu)。安(an)美達石(shi)(shi)(shi)(shi)英(ying)(ying)砂(sha)(sha)(sha)色選(xuan)機目前來說對(dui)于(yu)石(shi)(shi)(shi)(shi)英(ying)(ying)砂(sha)(sha)(sha)色選(xuan)主(zhu)要(yao)是針對(dui)其中黃點(dian)、黑點(dian)進行選(xuan)別，選(xuan)別的(de)(de)(de)(de)(de)范圍在2-40目，這個(ge)范圍效(xiao)果(guo)非常好，低(di)于(yu)40目得話由于(yu)石(shi)(shi)(shi)(shi)英(ying)(ying)砂(sha)(sha)(sha)太(tai)小造(zao)成的(de)(de)(de)(de)(de)好料(liao)(liao)浪(lang)費就比較嚴重(zhong)了。石(shi)(shi)(shi)(shi)英(ying)(ying)砂(sha)(sha)(sha)是石(shi)(shi)(shi)(shi)英(ying)(ying)石(shi)(shi)(shi)(shi)經破(po)碎(sui)加工(gong)而成的(de)(de)(de)(de)(de)石(shi)(shi)(shi)(shi)英(ying)(ying)顆(ke)粒，石(shi)(shi)(shi)(shi)英(ying)(ying)石(shi)(shi)(shi)(shi)是一種非金屬(shu)礦物質，是一種堅硬、耐磨、化(hua)學(xue)性能穩定的(de)(de)(de)(de)(de)硅酸鹽礦物，其主(zhu)要(yao)礦物成分是SiO2，石(shi)(shi)(shi)(shi)英(ying)(ying)砂(sha)(sha)(sha)的(de)(de)(de)(de)(de)顏色為乳白(bai)色、或無色半透明狀，莫氏硬度(du)7，石(shi)(shi)(shi)(shi)英(ying)(ying)砂(sha)(sha)(sha)是重(zhong)要(yao)的(de)(de)(de)(de)(de)工(gong)業礦物原料(liao)(liao)，非化(hua)學(xue)危險品，廣泛(fan)用于(yu)玻璃、鑄造(zao)、陶瓷及(ji)耐火材料(liao)(liao)、冶(ye)煉硅鐵(tie)、冶(ye)金熔(rong)劑、冶(ye)金、建筑、化(hua)工(gong)、塑料(liao)(liao)、橡膠、磨料(liao)(liao)、濾(lv)料(liao)(liao)等工(gong)業。
