Gravity Spiral Chute Description

Graqvity spiral chute is also called spiral chute or spiral chute separator, is the best equipment in mining and ore dressing industries, which is often applied to sort materials with size 0.3 - 0.02 mm, such as ilmenite, chromite, pyrite, zircon, rutile, monazite, phosphate, tungsten ore, tin, tantalum, niobium ore and other non-ferrous metals, precious metals and non-metallic minerals.

  • Introduction
Spiral Chute is a gravity separation equipment of separation different weight mineral by inertial centrifugal force pulp produced in helix turning motion.
  • Capacity
0.15~16t/h
  • Product Improvement
There are 3 kinds of chute for user to choose, glass steel chute, Xinhai wear-resistant rubber liner, polyurethane rubber liner.
 
Structure and Application of Spiral chute :
Spiral Chute is made up of feeder, feed chute, spiral flute, bracket, intercepting slot, and supporting frame, etc. 
Spiral chute is applicable to material separation of size 0.3 - 0.02 mm, such as of Iron ore, Ilmenite, Chromite, Pyrite, Zircon and Rutile, Monazite, Tungsten ore, Tin, Tantalum ore, Niobium mine and other non-ferrous metals, precious metals and non-metallic minerals, which with proportion differences. Spiral chute is 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.
Features and Working principle of Spiral chute: 
This Spiral chute has the features of:
1.Reasonable structure and small occupation area 
2.High recovery, high efficiency, and precise separation; 
3.Light in weight, rust and corrosion resistant; 
4.Simple installation and Minimal maintenance requirements 
5.Low operating cost and long operating life 
6.Reliable running with minimal operator attention.
chlorine plastic; the advantage is light, moisture proof, anti-rust, corrosion proof, properly suitable for the changing of the feeding size and chrome, granularity, grade. Concentration is high recovery, small footprint, less water consumption, simple structure, no driving force, big capacity, simple to install, convenient operation, small investment.
Advantages of Gravity Spiral Chute:
1. The spiral chute for sale is made of special PVC plastic, which is light and free from moisture, rust and corrosion; 2. It has small friction coefficient, high productivity and easy access to coal; 3. It is flame retardant and antistatic; 4. It has reasonable structure, and the floating coal can be cleaned easily. Tips for Maintenance of Gravity Spiral Chute Before starting spiral chute in mining, you should check whether the rotating direction of motor can meet the operating requirements. You should not dig out materials directly by hand or with other instruments during when the spiral chute is working. Materials in the tank are necessary to be cleaned up to prevent impurities entering into chunks. If rice stalks, straw and other fibrous impurities are found in the trough, you should stop it immediately.
