Product introduction
FRP Spiral Chute is a combination of spiral concentrator, spiral chute, shaker, centrifugal separator features of the equipment,is the best equipment for mining and mineral processing.Especially the seashore, Riverside, Sand Beach, Stream Road placer mining is more ideal.
 
Working principle
The spiral chute is composed of six parts of the feeder, the ore trough, the spiral groove, the product intercepting groove, the ore bucket and the trough bracket.The spiral piece is made of fiberglass (glass fiber reinforced plastic) and is bolted together.Glass fiber reinforced plastic spiral piece light and strong.Its separation face has a layer of wear-resistant layer, durable.The first end of the groove is provided with a multi tube-type feeding separator, which is homogeneous and easy to control.The evenly divided pulp is slowly given to the spiral groove by giving the ore trough..The tail end of the spiral groove is equipped with a valve block product intercepting groove, and the separated ore flow is divided into several products according to the grade.

Benefits

Spiral Chute has a reasonable structure, simple installation, covers an area of less, easy to operate, mineral processing stability, ore separation clear, processing volume, high efficiency of higher concentration concentrate, high recovery, reliable operation characteristics.
