Brief Introduction

Xinyu spiral chute is suitable for the materials whose granularity is 0.3~0.02mm such as iron, ferrotitanium, ferrochrome, pyrite, zirconated, rutile, monazite, tungsten ore, stannary and other nonferrous metals, rare metals and nonmetallic mineral.
Working Principle
When spiral chute stands and calibrates the vertical line, fix it with metal or wood in a certain place. The sand pump brings ore sand to the top two inlets on the screw and then add in replenish water to adjust the concentration. The ore oar naturally vortexes down and there is inertial centrifugal force in the rotating velocity cant. Due to the difference on the particle size and shape of the ore sand, the mines and sand are separated by the effect of gravity and centrifugal force. The concentrate flows into the pipe with pipe joint; backfilling flows into the pipe and is delivered to sand pool and then discharges by sand pump.


1. Xinyu high quality gold washing plant spiral chute has features of reasonable structure, simple installation, small floor space, simple operating, stable ore processing, large capacity, high efficiency and reliable operation.

2. The cost on preliminary stage, operating, maintenance and building is low.
3. The newest quick-wear part has long service life which is easy to repair and maintain.
