了解是什么影響選礦搖床選別礦物效果

發布日期:2019-09-12 作者: 點擊:

    給礦性質搖床給礦中礦粒的密度、粒度與開頭對分選指標影響很大。當重礦物與輕礦物的密度差大于1.5時,能在搖床順利分選。類似球形的礦粒與粗粒易被水沖走,所以球形與粒度差別有利的條件下,能分選密度差較小的礦粒。選礦搖床選別的給礦一般要將物料按等降比進行分級,即水力分級。

    洗水的用量與床面橫向坡度有關,在一定范圍內“大坡小水”和“小坡大水”可以獲得相近的選別效果。當坡度增大時,可以減少沖洗用水量,但是減少沖洗用量而增大坡度的辦法,將會使不同密度的礦物分帶變窄。當要求重礦物的質量較高時,一般都是采用較小的坡度而增大沖洗水的辦法。沖洗水與床面坡度是操作中經常調節的因素,當兩者調節適宜時,螺旋溜槽福彩快3在床面上就會出現分層區水流分布均勻,不起波浪,礦砂不成堆,精選區分帶明顯,帶寬而薄,床面無礦區寬合適。
