Product Description
Introduction of spiral chute
The spiral chute is a high-efficiency re-selection gravity separation equipment that makes use of the inertial centrifugal force generated by the ore pulp in the spiral rotation motion to separate light and heavy minerals. Spiral chute, integrated the characteristics of spiral concentrator, shaking table and centrifugal concentrator, is the best equipment for mining and beneficiation, especially for placer mining on seashores, riversides, sand beaches, and streams. It is made of the fiberglass lined withwear-resistant polyurethane and corundum cover; The advantages are light, moisture proof, and anti-rust, corrosive proof and no noise, properly suitable for the different feeding particle sizes and grades.
Features of spiral chute
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 corundum forms strong friction the concentration effect surpass plastic surface
Working principle
Raise the spiral chute and fix it in the proper position, sand pump transport 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.
