Spiral Chute

Spiral Chute

The spiral chute features easy controland installation, simple structure and operation, low cost, and stableoperation. It allows for feeding materials with wide density range, and offershigh concentration ratio, small land occupation area, and low waterconsumption. As a kind of gravity separating equipment, it requires no powersystem and hence is extraordinary energy efficient. Our spiral chute is designedfor separation of mineral ores with particle size between 0.02mm and 0.3mm, including iron ores, ilmenite, chromite,brasses, zirconite, rutile, monazite, xenotime, tungsten ore, tin ore,tantalum ore, niobium ore, and more mineral materials with different specificgravity.

Working Processes
Firstly, keep the spiral chute upright and fix it in a proper position usingsteel or wooden frames. Then, using sand pump to pump the ore slurry to the twofeeding holes at the top of the spiral chute, and meanwhile, add water into theslurry to adjust the slurry concentration. The slurry will flow downwardnaturally along with the spiral, and an inertial centrifugal force is generatedduring the process. Thus, the mineral ores and sand materials are separatedsuccessfully by the spiral chute due to their different specific gravity, grainsize and shape, etc. Finally, the ore concentrate flows into the specified orehopper, delivered via pipelines and collected. While sand materials areconveyed to the sand pond and discharged by sand pumps.
