CATHAY Rotating Spiral Chute is adjustable for more accurate mineral separation

CATHAY Rotating Spiral Chute: High-efficiency Sorting Equipment with Rotational Adjustment

1. Rotational Adjustment Design, More Flexible and Accurate Sorting

The rotation function is upgraded on the basis of the traditional spiral chute. The chute body can be rotated 360° through the drive device (rotation speed 0-5 rpm adjustable). When the slurry flows into the rotating spiral trough surface, it is not only affected by gravity and centrifugal force, but the dynamic adjustment brought by the rotation can make the slurry distribution more uniform and the mineral stratification clearer. The operator can adjust the rotation angle and speed in real time according to the characteristics of the ore type and the concentration of the slurry, and optimize the sorting parameters in a targeted manner, so that the enrichment accuracy of high-density useful minerals (such as ilmenite, zircon sand, etc.) is increased by 10%-15%, and the sorting error is controlled within 5%.

2. Enhanced sorting efficiency and significantly improved recovery rate

The rotation function accelerates the flow and mixing of the slurry in the trough, making the contact between the mineral particles and the trough surface more sufficient, and reducing the loss of fine-grained minerals due to untimely sedimentation. For minerals with a particle size of 0.05-2mm, the recovery rate is 8%-12% higher than that of fixed spiral chutes. Especially for slurries with high mud content, the centrifugal force generated by rotation can effectively separate mud from useful minerals, and the purity of the concentrate is increased to more than 90%, greatly reducing the subsequent processing costs.

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

It is not only suitable for the sorting of ilmenite, zircon sand, monazite, etc. in coastal sand mines and river sand mines, but also for the enrichment of fine-grained minerals in vein ore dressing, and the recovery of low-grade useful minerals in tailings. When processing slurries with complex components and large particle size fluctuations, the rotation adjustment can quickly adapt to material changes and maintain a stable sorting effect. It is widely used in small and medium-sized mines, mineral processing pilot plants and resource recovery companies.

4. Stable structure, reliable and durable rotation system

The trough body is made of high-strength fiberglass composite material, with a smooth and wear-resistant surface and excellent corrosion resistance. It can withstand long-term erosion of high-concentration slurry and has a service life of 6-8 years. The rotary drive system adopts precision gear transmission, combined with variable frequency speed regulation technology, which can be adjusted smoothly without jamming and has a low failure rate. The bearings are selected to be high temperature resistant and wear resistant models to ensure long-term stable operation under humid and dusty working conditions and reduce the frequency of maintenance.

5. Convenient operation, intuitive and controllable parameter adjustment

Equipped with a digital operation panel, you can set parameters such as rotation speed and tank inclination angle (adjustable from 5° to 20°) with one click, and display the operating status in real time. The equipment has built-in templates for sorting parameters of various types of minerals, which operators can directly call and fine-tune, and can quickly get started without professional experience. An observation window is provided to facilitate real-time observation of slurry flow and stratification, and timely adjustment of operation strategies.

6. Energy-saving design, economical operation cost

The power of the rotary system is only 1.5-3kW, and the energy consumption is lower than that of similar adjustable sorting equipment. Combined with the principle of non-powered basic sorting, the overall operating cost is reduced by more than 25% compared with traditional power equipment. The equipment has a compact structure, small footprint, and does not require a complex foundation for installation. It can be flexibly arranged on the existing production line to reduce the cost of site transformation.

7. Modular combination, flexible expansion of production capacity

The processing capacity of a single unit is 5-30 tons/hour, and it supports multiple units in parallel combination. The total processing capacity can be expanded to more than 100 tons/hour to meet the production needs of different scales. When multiple devices are linked, the rotation parameters can be uniformly adjusted through the centralized control system to achieve standardized sorting, improve overall production efficiency, and adapt to the long-term plan of increasing mine production capacity.

8. CATHAY brand guarantee, full-cycle service support

Each device undergoes a 72-hour load rotation test before leaving the factory to ensure that the rotation system and sorting performance meet the standards. Provide on-site installation and commissioning, operation training, regular maintenance and other services, 7×24-hour technical hotline response to fault consultation, sufficient reserves of wearing parts, to ensure the continuous and stable operation of the equipment, and escort the production of customers.
