试验室XLL-600型螺旋选矿机技术参数 Tech

XLL-600螺旋选矿机可以用于选别较粗粒的（0.02～2.0㎜）的金属矿物，如钨锡、磁铁、钛铁、鉻铁、砂金和海滨砂矿；它们也可以用于洗选4-6mm粉煤。

XLL-600 spiral concentrator can be used to  separate metallic minerals of coarse grain (0.02～2.0㎜) such as tungsten and tin, magnet,  ferrotitanium, ferrochrome, gulch-gold, and beach placer. They can also be used  to wash pulverized coal of 4-6mm.

一、工作原理

I. Working Principle

        螺旋选矿机有3-5圈具有一定倾斜度的螺旋槽，其断面呈抛物线或椭圆形。矿浆自上部给人后，在沿槽流动过程中发生分层。重矿物流向槽的内缘，轻矿物流向槽外缘。影响螺旋选矿机的技术操作条件主要有螺旋直径、螺旋槽横断面形状、螺矩、螺旋圈数、给矿体积、给矿浓度和冲洗水等。

This spiral concentrator has 3 to 5 circles  and slightly tilting spiral groove. Its section is in the shape of parabolic  curve or ellipse. After the slurry is fed in the upper part, it becomes layered  during the process when it flows along the groove. The heavy minerals flow to  the inner edge of the groove while the light minerals flow to the outer edge of  the groove. Conditions which can affect the technical operation of the spiral  concentrator mainly include the diameter of screw, transverse shape of spiral  groove, helix pitch, number of spiral coils, feeding volume, feeding  concentration, flushing water, etc.
