Product Details

Introduction of gold mining spiral chute

Spiral chute is a gravity separation equipment of separation different weight mineral by inertial centrifugal force pulp produced in helix turning motion. It is the ideal gravity concentration equipment to separate non-ferrous metals, ferrous metals, non-metallic mineral and rare metal mineral. It is also called gravity spiral chute, spiral separator and spiral chute separator.


With the advantages of light in weight, moisture proof, and anti-rust, corrosive proof and no noise; properly suitable for different feeding particle sizes and grades.

Spiral Chute Conveyor

Features of gold mining spiral chute

1. Reasonable structure, simple installation and operation, stable, easy control and reliable operation

2. Small cover space, less water consumption, no need of power.

3. Stable ore beneficiation, clear ore separation, high processing capacity and efficiency.

4. Large capacity, enrichment ratio, high recovery rate

5. Light weight, moisture, rust and corrosion resistant, adaptable to fluctuations in ore concentration, particle size, grade, no noise, etc.

Gold Spiral Separator

Working principle of gold mining spiral chute

Spiral chute is assembled by the screw blade which is made of glass fiber reinforced plastic. The inner surface of the blade is equipped with resistant lining that is made of urethanes or the epoxy resin mixed emery.


Spiral chute is supported on a metal structure shelve. Above it, there are mineral separation machine and receiving shaft, while the products interception machine and the receiving shaft are on the lower part.

Gravity Chute Conveyor

Bring ores to the two feeding ports on the head of spiral chute by sand pump. Add water. Adjust the destiny of ore pulp. The ore pulp will fall down because of gravity. A type of centrifugal force will product during this process.


The ore and sand will be divided because of different weights, sizes and granularities by the force of gravity and centrifugal force. Concentrate will flow out though tube. Tailings will flow into the tailings bucket and then be discharged out by a pipe.
