Spiral chute
A spiral chute is the best concentrating equipment, especially for concentrating sand ore in seashore and riverside. It is made of fibreglass lined with wear-resistant polyurethane and corundum cover.
The advantages are light, moisture-proof, anti-rust, corrosive proof and no noise, properly suitable for different feeding particle sizes and grades. The separator machine is a gravity spiral separating machine.
The slurry produced inertia centrifugal force in rotary motion, and with gravity help in the same time, to promote light and heavy mineral zonation in the spiral chute, and continuous discharge respectively.
Feeding Size (mm): 0.02-0.4
Production capacity: 0.2-10 t/h
Spiral chute features
1. Reasonable structure and small occupation area.
2. High recovery, high efficiency, and precise separation.
3. Non-required power.
4. Light in weight, anti-corrosion, rust and wear-resistant.
5. Simple installation and Minimal maintenance requirements.
6. Low operating cost and long working life.
7. Reliable running with minimal operator attention.
8. Strong adaptability to fluctuation of feeding amount, density, size and grade.
9. The surface of the corundum forms strong friction the concentration effect surpasses the plastic surface.
Spiral chute working principle
Raise the spiral chute and fix it in the proper position, the sand pump transports 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.
