The features of Hongji chute operate:
1)less water consumption
2)simple structure
3)no driving force
4)big capacity
Chute operate working principle:
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 coveyed out by pipe and picked up, and final sand flows to final sand hopper and coveyed out by pipe to sand pond. Then remove the sand pump. That is the whole concentrating process
