Spiral Chute Overview

The spiral separator/ spiral chute is the earliest mining machine. It has been used to classify the granularity of 0.3-0.02 millimeters fine grain like iron, tin, tungsten, tantalum-niobium, gold ore, coal mine, monazite, rutile, zircon, and other metals. The non-metallic minerals have a big enough specific gravity difference.

Spiral chutes are gravity concentrators and separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force, and other forces in the fluid medium. The spiral separator is the best equipment for mining and mineral processing, which combines the characteristics of the spiral concentrator, shaking table, and centrifugal concentrator. It is made of the fiberglass lined with wear-resistant polyurethane and corundum cover, light moisture-proof, anti-rust.

Structures & Working Principle

Spiral Chute Structure
The main parts of a spiral chute are feeder chute, trough pillar, product collection funnel, product intercepted slot, spiral chute, tripod, etc.,

Sprial Chute Working Principle
Raise the spiral chute and fix it in the proper position, sand pump send the ore to the feed inlet, adding water to adjust the concentration of the slurry. The slurry naturally swirls from high to low and generates an inertial centrifugal force in the rotating bevel flow rate. The mineral is separated from the sand by the gravity and centrifugal force of the swirl by the difference in specific gravity, grain size and shape of the ore. The concentrate flows into the concentrate bucket and is connected by the pipeline. The tail sand flows into the tailing sand bucket and is connected to the sand pool by the pipeline, and then drained by the sand pump to complete the whole process of the beneficiation.
