A gravity chute in the form of a continuous helical trough spiraled around a column for conveying materials to a lower level. - details see: https://www.machineto.com/glass-fibre-reinforced-plastic-spiral-chute-utilized-in-fine-ore-separation-10317738

SPIRAL CHUTE INTRODUCTION

This device is suitable for sorting grain size 0.3 – 0.02 mm fines iron ore , ilmenite , chromite , pyrite , zircon , rutile , monazite, phosphorous ore, tungsten ore, tin , ore of tantalum , niobium ore, as well as differences in the proportion of other non-ferrous metals, rare metals and non-metallic mineral body . This equipment has the sorting process is stable , easy to control, to allow changes to the mineral concentration range , enrichment is high, and high recovery rate, small footprint, water consumption.

Spiral chute erected, calibration of the vertical line, metal frame or wood fixed in the right position by the sand pump ore sent to the spiral feed inlet at the top two, add supplementary water, adjust the concentration of ore oar ore oar natural down from the high swirl, in a rotating inclined plane velocity to produce a kind of inertia, centrifugal force, the proportion of ore particle size, shape differences, through the swirl of gravity and centrifugal force to separate ore and sand, fine mine into the concentrate bucket pick out pipe, the tailings flow into the tailings bucket receiving the pipe sand traps, and then the sand pump to drain away, completed the whole process of dressing.

SPIRAL CHUTE OPERATION

The main parts of a spiral concentrator include feeder, frame, Spiral Chute and output chute etc. Spiral concentrator is fixed by a piece of timber or hob in place. The mineral sand is sent by pump to the two material entrances at the top of spiral. And then operators add enough water and accommodate the density of mash, which flows from the top to the bottom naturally. A centrifugal force of inertia was produced on the slope in the velocity of rotation.

According to the different proportions, granularities, shapes of the mineral sand, mineral sand will be divided by the effect of gravity and centrifugal force. Concentrated ore flow into ore bucket. Tailings are pumped to the tailing pond where a draw-off pump works. The above is the whole process of material separation.

BUY SPIRAL CONCENTRATOR AT OUR COMPANY

It has been proved that spiral concentrator works efficiently in a coal separating plant. This useful equipment combines with traditional system of slack-coal and coal-slurry. Compared with the system of water-only cyclone, the investment and operation cost of spiral concentrator is much lower. This spiral chute comes with advantages of high capacity, excellent efficiency, superior recovery, and reliable operation. Undoubtedly, spiral chute is ideal equipment for investing in mining industry.

If you choose a spiral concentrator, you can save much budget for your factory buildings, and need not worry about the large expense on heating or ventilation.
