spiral chute ore dressing equipment Low operating cost and long
operating life
spiral chute
Spiral chute are 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.Spiral separators are made of polyurethane lined fiber
glass with wearable corundum inner surface.
Spiral chute, is a comprehensive spiral dressing machine, spiral
chute, shaking table, centrifugal dressing machine characteristics
of equipment, make mining, the best equipment, especially the
seashore, riverside, sand beach, stream road of the sand mining is
more ideal.
Device use
This equipment is suitable for sorting iron ore, ilmenite,
chromite, pyrite, zirconium, rutile, monazite, phosphenite,
tungsten ore, tin ore, tantalum ore, niobium ore and other
non-ferrous metals, rare metals and non-metallic ore objects with
different specific gravity.This equipment has the advantages of
stable separation process, easy control, large allowable variation
range of ore concentration, high enrichment ratio and high recovery
rate.
Small footprint, less water consumption, simple structure, no
power, large handling capacity, simple installation, convenient
operation, small investment and quick effect.
Structure:
The spiral chute is composed of a feeding homogenizer, a cross
(tripod), a feeding groove, a spiral groove, a cutting groove, a
gathering bucket and a groove pillar.
Usage:Calibration will spiral chute stand, vertical line, with
metal or wood in the right place, by sand pump will ore to screw on
the top two inlet, to join the replenish water, adjust OARS
concentration, ore oar natural vortex, down from a high in the
rotating velocity cant produce a kind of inertial centrifugal
force, with the proportion of ore, the difference of particle size,
shape,The gravity and centrifugal force of the swirl separate the
ore from the sand,
The concentrate flows into the concentrate bucket and is connected
out by pipeline, and the tailings flow into the tailings bucket is
connected to the sand pond by pipeline, and then drained away by
sand pump, which completes the whole process of beneficiation.
Principle
When using the chute when the vertical line need to be calibrated,
the ore is sent to the feed mouth. adding additional water. After
adjusting the concentration of mineral by adding additional water.
The paddle streams down from the high place. In bevel velocity will
produce a centrifugal force. Under the action of gravity and
centrifugal force, ore and sand will be separated from each other.
The tailings then flow into the tailings and the sand is drain away
by pump to complete the whole process of the beneficiation.
Advantages
Reasonable structure and small occupation area;
High recovery, high efficiency, and precise separation;
Light in weight, rust and corrosion resistant;
Simple installation and Minimal maintenance requirements;
Low operating cost and long operating life;
Reliable running with minimal operator attention;
Strong adaptability to fluctuation of feeding amount, density, size
and grade;
