Product Description

Spiral chute separator is the most popular gravity separator machine for mineral separation, which is suitable for separating 0.8-0.074mm slurry ores. Sometimes the size could be -3mm. 

The MINERALS includes Coal, iron ore, ilmenite, chromite, pyrite, tungsten ore, tin ore, tantalum niobium ore, placer gold, zircon, rutile, monazite, phosphate Bore and other non-ferrous metals, rare metals, and non-metallic materials.

Machine Structure

Spiral separator chutes are made of fiberglass lined with wear-resistant polyurethane and corundum cover, which makes the spiral chutes are wearable. 

3. Parts of spiral chutes

              Top of the spiral chutes                                                            spirals                                                        the bottom of spiral chutes

How do the spiral chutes wash minerals?

Vertical installed the spiral chutes, fixed them by the iron frame or wood in a suitable position. The sand is sent to the two feeding ports on the top of the spiral chutes by the sand pump, and adjust the density of the slurry ores. The slurry naturally was fed from the high to the low, and an inertial centrifugal force is generated in the rotating inclined flow velocity.

According to the difference in the specific gravity, particle size, and shape of the ore sand, the gravity of the cyclone is passed With the action of centrifugal force, the ore and sand are separated. The concentrate flows into the concentrate hopper and is connected with the pipeline. The tailings flow into the tailing bucket and connected to the sand tank by pipeline, and then discharged by the sand pump. The whole process of mineral processing is completed.

Working Principle

1. Take a small space, process large capacity. 
The spiral chute occupies a small area and has a large processing capacity;

2.Moisture, rust, and corrosion resistance
Anti-rust, anti-corrosion, lightweight;

3.Reasonable structure:
Reasonable structure, simple installation, and easy operation;

4.no need power:
It has strong adaptability to the fluctuation of feed rate, concentration, particle size, and grade, and has no noise.

5.The sorting index was stable
The operation conditions of the spiral chute (such as feed particle size, pulp concentration, etc.) are not harsh, and the separation index is relatively stable;

6.Stable performance.
It is stable in mineral processing, can get concentrate, middling, and tailings (in special cases, it can be divided into 4 kinds of ores), large treatment capacity, high efficiency, high concentration ratio, high recovery rate, and reliable operation.


Case Analysis

Mineral: Tin ores
Process: Firstly use the spiral chutes to select the tailings, then use the spiral chutes and shaker table to rough select the coarse particle, and the last step to remove the sulfur ores and Arsenite.
Grade of Tin concentrate: 47.61%
Recovery of tin: 75.71% 

Step 1: Using Spiral chutes can remove 60% tailings, the coarse tin concentrate grade can be 1.23% and the recovery rate of tin can be 89.21%. Successfully achieve the purpose of preliminary collection and removing the tailings. 

Step 2: Using spiral chutes and shaking tables to select the coarse concentrate, which can get 24.47% grade of tin, and recovery 81.99% of tin concentrate from shaker tables.
