1. Overview

Spiral chute is a new type of gravity concentration equipment for separating 0.6-0.05mm (can separate 2mm material under special circumstances) fine particle ore, including iron, ilmenite, chromite, pyrite, tungsten, tin, tantalum-niobium, alluvial gold, zircon, rutile, monazite, phosphorus and other non-ferrous metals, rare metals, non-metallic minerals with specific gravity difference.

Spiral chute with advantages of stable dressing, clear separating, large capacity, high efficiency, strong adaptability to feeding capacity, density, granularity, fluctuations of grade, simple installation, small footprint, simple operation, moisture-proof, antirust , corrosion, no power, no moving parts, no noise, etc., it is particularly suitable for placer extracting in seaside, river, sand beach, and stream.

2. Structure

Spiral chute is mainly composed of 9 parts as the following picture shows. And its main six types of models are with diameters of 2000mm, 1500mm, 1200mm, 900mm, 600mm, 400mm(laboratory use).
