豫暉公司推出一種花崗巖尾礦砂處理方法

        尾礦害處:
        1、尾礦堆放占用耕地,阻礙河床,含有的藥劑會侵入土壤和河流;
        2、顆粒度較小的尾礦砂漂浮空中,污染大氣;
        3、尾礦庫管理費用巨大;
        尾礦可利用價值:
        1、有用金屬元素再選,可用于墻體、陶瓷、砂漿骨料等領域;
        2、作土壤改良劑及微量元素肥料;
        3、利用尾礦復墾植被。
        但是,目前我國尾礦利用率較大,具有極大的可利用空間。
 

工藝圖

        豫暉公司推出一種花崗巖尾礦砂處理方法,工藝如上圖。首先,通過給料機將花崗巖尾礦砂輸送到前列破碎機;其次,將經過破碎后的物料輸送到滾動篩分機進行篩分;再次,經篩分后從滾動篩分機下部落下的物料進入整形制砂機,留在滾動篩分機篩子內的物料送到第二次破碎機破碎;較后,經整形制砂機處理以及經第二次破碎機破碎的物料送到分析振動篩做如下分層篩選處理得到精細瓷粉,耐火材料,成品砂和微細陶瓷。
        該花崗巖尾礦砂處理方法有利于緩解礦山原料來源的減少,并有利于在材料應用上形成新功能材料礦源的創造性開發,實現了在花崗巖尾礦砂的資源再利用,使得環保成本大大降低。
