CATHAY hydraulic classifier: expert in precise sorting of fine-grained materials

1. Hydraulic sorting, scientific and efficient classification principle

Material classification is achieved by the synergistic effect of water medium and gravity sedimentation. During operation, water rises evenly from the bottom of the classification tank to form a stable rising water flow. After the material enters the tank with the slurry, particles of different sizes are separated due to the difference in sedimentation speed: coarse particles are greatly affected by gravity, overcome the rising water flow and settle to the bottom of the tank, and are discharged by the discharge device; fine particles rise with the water flow and are collected through the overflow port. The whole process does not require violent mechanical action, and the classification process is gentle, avoiding excessive crushing of materials and effectively protecting the particle morphology.

2. Accurate fine particle classification and stable particle size control

Designed specifically for fine-grained materials, it can accurately separate particles in the range of 0.01mm-0.5mm, and the classification accuracy can reach more than 90%. By adjusting parameters such as the rising water flow rate and the liquid level height of the classification tank, the classification particle size can be flexibly controlled to meet the requirements of fine material purity in different scenarios. After classification, the particle size distribution of the material is concentrated, and the boundary between coarse and fine is clear, which avoids the mixing of coarse particles into fine particles or the entrainment of fine particles into coarse particles, providing high-quality raw materials for subsequent flotation, filtration and other processes.

3. Adapt to multiple materials and wide application scenarios

It can handle the purification and classification of fine tailings of metal mines (such as gold and silver mines) and non-metallic minerals (such as kaolin and talc). It can also be used for the sorting of fine materials such as chemical raw materials and ceramic raw materials. It is widely used in mining beneficiation, fine chemicals, building materials processing and other fields. Especially in the scene of fine-grained material purification, it can effectively remove impurity particles and improve the purity of finished products. For example, the whiteness of kaolin can be increased by 5%-10% after classification.

4. Water-saving and energy-saving, economical operating cost

The circulating water system design is adopted, and the rising water flow can be reused. The water consumption is reduced by more than 30% compared with traditional grading equipment, which meets the requirements of water-saving production. The power of the equipment is mainly used for water circulation and material transportation, with low energy consumption. The energy consumption per unit processing volume is only 60% of that of mechanical grading equipment. Long-term use can significantly reduce production costs. At the same time, there is no violent mechanical friction when the equipment is running, and the noise is low, creating a quiet production environment.

5. Reasonable structural design, stable and reliable operation

The grading tank is made of corrosion-resistant materials, such as stainless steel or polymer wear-resistant materials, which can withstand long-term erosion by acid and alkali components in the slurry and extend the service life of the equipment. The rising water flow distribution device is precisely designed to ensure uniform and stable water flow and avoid abnormal local flow rate affecting the grading effect. The transmission system uses high-quality motors and reducers, which run smoothly and have a low failure rate, ensuring continuous and stable operation of the equipment and reducing downtime.

6. Easy operation, convenient and worry-free maintenance

Equipped with an intelligent control panel, the grading effect can be accurately controlled by adjusting parameters such as water flow rate and liquid level height. The operation is intuitive and easy to understand, and novices can get started after simple training. The equipment has a compact structure, a reasonable layout of key components, a convenient location for maintenance ports, and convenient daily cleaning and inspection. There are few wearing parts and they are easy to replace, such as distribution plates and discharge valves, with a long maintenance cycle and reduced operation and maintenance costs.

7. Gentle separation to protect material properties

Different from the forced separation method of mechanical grading equipment, the material is only affected by water flow and gravity during hydraulic grading, and the particle shape is not easily destroyed. It is especially suitable for materials with high requirements for particle shape, such as glass raw materials, ceramic particles, etc., which can retain the original characteristics of the material to the greatest extent and improve the quality of the finished product.

8. Brand guarantee, thoughtful and worry-free after-sales
