CATHAY spiral chute, gravity centrifugal synergy, efficient mineral separation

CATHAY spiral chute: efficient sorting equipment driven by gravity and centrifugal force

1. Double force synergy, precise and efficient sorting

Relying on the unique spiral trough structure, when the slurry flows in from the top feed port, it slides down the trough surface under the action of gravity, and centrifugal force is generated due to the rotation of the trough. The two forces work together to achieve stratification of minerals of different densities in the slurry: high-density useful minerals (such as gold, tin, ilmenite, etc.) are affected by centrifugal force and gather to the inside of the trough, and are discharged along the inner flow channel as concentrates; low-density gangue minerals are discharged along the outer flow channel as tailings. The sorting efficiency of a single device can reach more than 80%, and the recovery rate of fine-grained minerals (0.074-2mm) is 10%-15% higher than that of traditional gravity separation equipment.

2. No power drive, significant energy-saving advantages

No additional power device is required, and the sorting is completed only by the material's own gravity and the centrifugal force generated by the trough structure, which fundamentally reduces energy consumption. Compared with the power sorting equipment with the same processing capacity, the operating cost is reduced by more than 30%, which can save a lot of electricity bills every year. It is especially suitable for mining enterprises with tight energy supply or focusing on low-carbon production. While improving sorting efficiency, it can achieve green and energy-saving production.

3. Adapt to multiple types of minerals and cover a wide range of scenarios

It has outstanding performance in the field of sand ore sorting, and can efficiently process sand ore resources such as gold, tin, zircon sand, monazite, and ilmenite; the tailings after vein ore sorting can also be effectively recycled to improve resource utilization. It is widely used in coastal sand ore and river sand ore mining sites, as well as the rough and fine selection of minerals in small and medium-sized ore dressing plants. Whether it is large-scale industrial production or small-scale experimental sorting, it can stably perform its performance.

4. Unique structure and strong durability

The trough body is molded with high-strength fiberglass material, with a smooth surface, wear-resistant and corrosion-resistant, which can withstand long-term erosion of high-concentration slurry. The service life is up to 5-8 years, which is more than double that of ordinary steel trough bodies. The curvature radius and slope of the spiral trough are precisely calculated to ensure the stability of the slurry flow speed and avoid fluctuations in the sorting effect caused by unreasonable structure. The overall weight of the equipment is light, and no complex foundation is required for installation. It can be quickly fixed on the bracket and put into use.

5. Easy operation, no professional skills required

No complex parameter adjustment is required, just control the feed concentration (generally 20%-30%) and feed amount to operate stably. The sorting process of the slurry in the trough is intuitively visible. The operator can judge the sorting status by observing the distribution of the ore belt on the trough surface, and can start operation without professional training. There is no noise or vibration during the operation of the equipment, which provides good protection for the operating environment.

6. Low consumption and environmental protection, in line with green standards

Except for the feed pump, there are no other power components, and the energy consumption is extremely low; no chemical agents are used in the sorting process to avoid pollution to minerals and the environment. The tailings after sorting can be directly used for backfilling or other comprehensive utilization, which meets the requirements of green mine construction. The trough material can be recycled, and the equipment has little impact on the environment after being scrapped, realizing the environmental protection concept of the whole life cycle.

7. Multiple specifications are available to adapt to different production capacities

It provides multiple specifications such as diameter 300mm, 600mm, 900mm, 1200mm, etc., and the processing capacity of a single unit ranges from 0.5 tons/hour to 20 tons/hour. According to the production capacity requirements of the mine, you can choose to use a single unit or a combination of multiple units. When multiple units are connected in parallel, the processing capacity can be linearly superimposed, which can easily meet the production needs from small workshops to medium-sized ore dressing plants, and the expansion is flexible without the need for large-scale transformation of production lines.

8. CATHAY brand guarantee, worry-free service throughout the process

Each spiral chute has undergone rigorous water pressure testing and trial operation with materials to ensure that the trough body is leak-free and the sorting effect meets the standards. We provide on-site installation guidance, operation skills training, regular return visits and maintenance services, 7×24-hour technical hotline to respond to customer inquiries at any time, and provide personalized sorting solution suggestions for different types of ores, so that customers can use it more safely and produce more efficiently.
