We were established as the most specialized mineral processing equipment company since 1985.
The mineral dressing spiral chute is a scientific and technological product developed by our company through years of mineral processing experience. It is the best equipment for mining and mineral processing, especially for placer mining on seashores, riversides, sand beaches, and streams.
The spiral chute is a gravity separation equipment that utilizes the inertial centrifugal force generated by the pulp in the spiral rotary motion to separate light and heavy minerals. The glass fiber reinforced plastic spiral chute is used to separate fine-grained iron ore, tin ore, tungsten ore, gold mines etc.
The spiral chute has the advantages of reasonable structure, simple installation, small footprint, simple operation, stable ore dressing, clear ore separation, large processing capacity, high beneficiation and enrichment ratio, high recovery rate, and reliable operation.
1. The sorting process is stable and easy to control, and the allowable change range of the ore concentration is large.
2. Light weight, moisture-proof, rust-proof, corrosion-resistant, and strong adaptability to fluctuations in ore feed, concentration, particle size, and grade.
3. High enrichment ratio, high recovery rate, large processing capacity, and small footprint.
4. Reasonable structure, simple operation, stable beneficiation, simple installation.
5. No power, no noise.
The working principle of the spiral chute is to use the inclined plane water flow method to sort according to the specific gravity difference of minerals. The slurry mixture is fed into the chute with a small inclination angle (generally 3 to 4 degrees, generally no more than 6 degrees), and the ore particles are layered according to the density under the combined action of the impact of water flow, gravity, centrifugal force, and friction. Since the speed distribution of the water flow in the tank is large in the upper layer and smaller in the lower layer, the denser ore particles are concentrated in the lower layer, and they move slowly along the bottom of the tank due to the momentum of the water flow and the greater friction at the bottom of the tank; The particles are concentrated in the upper layer, carried by the water flow, and flow out of the tank at a relatively fast speed. Then, two kinds of products with different densities, concentrate and tailings can be obtained by intercepting the flow separately by layer.

It’s a main gravity separation machine, according to the difference in material specific gravity, particle size, shape, a centrifugal flow formed on the spiral slope, under the combined action of gravity and centrifugal force in order to separate light material from heavy materials.
Widely used in tungsten ore, tin ore, iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, coal, etc
Its main part is spirals, made of FRP (glass fiber reinforced plastic)
It has the advantages of small footprint, low water consumption, simple structure, no need for power, large processing capacity, simple installation, easy operation, small investment and quick results.
Model 5LL-1200 is the most widely used model, with process capacity 3-4 tons per hour.
Normally the lifetime is 3-4 years.
We provide the best mine processing solution in the industry. We design our products with performance and efficiency, trusted over the years and recognized by many countries. Let’s get you started.
