CATHAY spiral classifier spiral sorting particle size precise separation

The spiral classifier is a kind of equipment that uses the principle that the solid particles have different specific gravities and different precipitation speeds in the liquid to perform mechanical classification. It is widely used in ore dressing plants to form a closed-loop circulation with the ball mill to divert ore sand, or to classify ore sand and fine mud in gravity ore dressing, to grade the ore pulp in the metal ore dressing process, and to remove mud and water in ore washing operations.
product introduction
CATHAY spiral classifier: core equipment for precise material particle size sorting
1. Spiral transmission, scientific and efficient classification principle
Using a unique spiral blade transmission structure, material classification is achieved by relying on the synergistic effect of gravity sedimentation and spiral conveying. During operation, the slurry enters the classification tank from the feed port, and the coarse particles quickly settle to the bottom of the tank due to the large gravity, and are pushed to the discharge port by the rotating spiral blades; the fine particles overflow to the overflow tank with the slurry to complete the separation of coarse and fine materials. The whole process is continuously automated, and the classification efficiency is more than 20% higher than that of traditional equipment, ensuring fast and accurate material sorting.
2. Accurate classification, stable and reliable particle size control
By optimizing the spiral speed, the inclination angle of the classification tank and the height of the overflow weir, the classification particle size can be accurately controlled, and the materials in the range of 0.074mm-1mm can be effectively separated, and the classification accuracy error is ≤5%. Whether it is coarse or fine particle classification, it can ensure that the particle size of the same batch of materials is uniform, avoid the mixing of coarse and fine particles, provide stable quality raw materials for subsequent mineral processing, grinding and other processes, and improve overall production efficiency.
3. Wide adaptability and strong material compatibility
It can process metal ore slurries such as gold, copper, iron, lead and zinc, and can also grade non-metallic mineral materials such as limestone, quartz sand and kaolin. It is widely used in mining beneficiation, building materials processing, metallurgy and smelting industries. Whether it is high-concentration slurry or low-concentration slurry, it can operate stably, especially in the closed-loop circulation system of the ball mill, unqualified coarse materials can be returned to the mill for re-grinding, greatly improving resource utilization.
4. Strong structure and outstanding durability
The grading trough is welded with thickened steel plates, which is impact-resistant and wear-resistant, and can withstand long-term erosion of high-concentration slurry; the spiral blades are made of high manganese steel or wear-resistant rubber, and the surface is specially treated with high hardness and strong wear resistance, and the service life is extended by more than 30% compared with ordinary materials. The equipment transmission system adopts a high-precision gearbox, which runs smoothly and has a low failure rate, ensuring long-term continuous production without interruption.
5. Easy operation, worry-free operation and maintenance
Equipped with a simple control panel, the grading effect can be easily controlled by adjusting the spiral speed, and the operator can get started after simple training. The equipment structure is reasonably designed, and maintenance windows are set at key parts, which are convenient for daily inspection and cleaning; the gap between the spiral blade and the trough can be flexibly adjusted to reduce wear and the risk of jamming. The replacement process of wearing parts is simple, no complex tools are required, and the maintenance cost is 15% lower than that of similar equipment.
6. Energy saving and low consumption, in line with green production standards
Adopting low-power motor drive, the operating energy consumption is 15%-25% lower than that of traditional classifiers, and long-term use can significantly save electricity expenses. The equipment has low noise during operation, and with the sealed design, it reduces slurry leakage and dust pollution, which meets environmental protection requirements. There is no additional material loss during the grading process, and the resource utilization rate is high, which helps enterprises achieve green and sustainable production.
7. Adapt to production lines and strong integration
It can be seamlessly connected with equipment such as ball mills, crushers, flotation machines, and easily integrated into mineral processing production lines or material processing processes. Whether it is a single machine operation or an automated production line, it can be efficiently adapted to reduce the connection cost between equipment. The equipment is easy to install and occupies a small area. The installation position can be flexibly adjusted according to the layout of the production line to optimize the use of workshop space.
