The difference between spiral chute and spiral concentrator and its application
The shape and working principle of spiral chute and spiral concentrator are basically the same, but there are differences in structure, performance and use between them. The main differences are as follows:
1、The bottom section of the spiral concentrator is a parabola or a part of the ellipse, while the bottom section of the spiral chute is a cubic parabola, so the bottom width of the spiral chute is smooth and smooth, which is more suitable for the treatment of fine grain material.
2、The spiral chute is connected with the fining, middle and tailings at the end of the groove, while the spiral concentrator intercepts the concentrate at the upper part and the tailings at the end of the trough;
3、There is no washing water in the spiral chute, and washing water is added to the screw concentrator;
4、The granularity of spiral chute is smaller than that of spiral concentrator. The suitable granularity of spiral concentrator is 0.074 ~ 2mm, and the suitable granularity of spiral chute is 0.04 ~ 0.3mm.
5、For the feed concentration, the spiral chute requires high concentration, generally not less than 30%, while the screw concentrator concentration requirements are not strict, the lower limit can be up to 10%.
  The advantages of the two kinds of equipment are no moving parts, simple structure, small area, large processing capacity, visual sorting process and easy operation. The disadvantage is that the equipment has high shape size, high concentrate yield and poor recovery effect on spherical gold. In gold mine, these two kinds of equipment are mainly used to produce gold from flotation tailings.
   The screw concentrator is mainly used to separate 3.0~0.5mm ores containing tungsten, tin, iron, niobium, tantalum, and ore containing ilmenite, rutile, zircon, monazite, gold and platinum. Debris, etc. During operation, the ore feed and pulp concentration should be stable, and weeds, wood chips and other sundries should be removed in advance.
The spiral chute is mainly used for separating iron , tungsten , tin , titanium iron ore from 0.2 - 0.02mm and treating ore sand containing titanium - iron ore , rutile , zircon , monazite and gold .
