This device is suitable for sorting size 0.3 - 0.02 mm thin material of iron
ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, phosphorus B ore,
tungsten ore, tin, tantalum ore, niobium ore as well as the proportion of
differences and other nonferrous metals, rare metals and non-metallic mineral
body. The sorting process is stable, easy to control, allow changes in ore
concentration range, enrichment ratio, high recovery rate, small footprint,
water consumption, simple structure, large capacity, easy to install, easy
operation, small investment and quick advantages.Spiral chute consists of mine
homogenizer, crosses (tripod), mine shafts, helical groove, the interception of
slots, gathering hopper, tank pillars.Suitable for roughing equipment, widely
used in processing tungsten, tin, gold, platinum, iron ore and certain metals,
especially in dealing with the application of low-grade placer.
Stick up the spiral chute, adjust vertical line, and fix it to a proper place
with hob ore timber; deliver the ore slurry to the two feeding opening at top of
the spiral chute with the help of sand pump; add supplementary water to adjust
slurry thickness. Then slurry flows down automatically and rotarily from the
top. A inertial centrifugal force is formed along the rotary bevel with flow
speed, so that ore and sand can be divided under rotary steam and centrifugal
force according to the slurry's different specific gravity, grain size and
shape. Next, final ore flows to the final ore hopper and conveyed out by pipe
and picked up, and final sand flows to final sand hopper and conveyed out by
pipe to sand pond. Then remove the sand pump. That is the whole concentrating
process.
