选矿设备螺旋分级机螺旋小叶片改造

Mineral Processing Equipment of Screw Grader Blade Transformation

在选矿行业中,螺旋分级机作为一种选矿的分级设备,目前尚在普遍应用。螺旋是分级机的关键部件,以卡箍方式装有与螺旋导角相适应的螺旋支架板,用来连接小叶片。螺旋分级机的小叶片(又称刀片)一般采用铸铁制作,使用寿命短,频繁的更换对正常生产以及生产成本有较大的影响。现就本单位分级机螺旋小叶片改造经验探讨。

In beneficiation industry, hierarchic machine of helix is one kind of the hierarchic equipment dressing ore, is in at present still common application. Spiral classifier is a key part to clamp mode with and adapt to the helix lead Angle of helical supporting plate, used to connect a small blade. Small blade spiral classifier （also known as blade） generally made of cast iron, short service life of frequent replacement has a larger effect on normal production and production cost. Now for the purpose of this unit, a small spiral classifier reform experience.
