An Alumina ceramic hydrocyclone is a device that uses centrifugal force to classify and separate particles. Its interior is lined with alumina ceramic to improve wear and corrosion resistance.

Structure and Operating Principle

·Structure: It typically consists of a hollow cylinder at the top and an inverted cone at the bottom. The cylinder has a tangential feed inlet, an overflow pipe at the center of the cylinder, and a grit nozzle at the end of the cone. Other auxiliary components include a feed pipe and overflow duct.

·Operating Principle: The slurry to be separated enters the cyclone body at high speed and tangentially under the action of a feed pump. Larger, denser particles in the slurry are driven toward the walls by centrifugal force, spiraling downward along the walls and ultimately discharged from the underflow outlet as grit. Smaller, less dense particles and most of the liquid, however, remain near the centerline of the cylinder due to the reduced centrifugal force. They move upward with the slurry and are discharged from the overflow pipe as overflow, achieving particle classification and separation. Material Advantages

· High Wear Resistance: Alumina ceramics offer exceptional hardness and wear resistance, effectively resisting erosion and wear from particles in the slurry, extending equipment life by more than three times compared to traditional metal cyclones.

· Corrosion Resistance: Alumina ceramics exhibit excellent chemical stability, withstanding corrosion from corrosive media such as acids and alkalis, making them suitable for a variety of complex working conditions.

· High Strength and Toughness: Some alumina ceramics, such as ZTA ceramics (zirconia-toughened alumina), combine high hardness with high toughness, offering excellent impact resistance and the ability to withstand the impact of high-speed slurry inflow.

· Product Features

· Simple Structure: No moving parts, enabling easy operation and maintenance.

· High Processing Capacity: High throughput per unit volume, compact footprint, and adaptable to high flow rates and high-concentration slurries.

· High Classification Efficiency: Achieves fine classification, with a classification efficiency approximately 10% higher than that of conventional cyclones, effectively improving product quality. Application Areas

· Mineral Processing: Used for grading, concentrating, and desliming ores. For example, in the beneficiation process of gold and copper ores, ore pulp is graded to improve the concentrate grade.

· Coal Washing: Used for sorting and processing coal, separating coal slimes of varying densities and water, achieving coal grading and sorting.

· Alumina Production: In the alumina production process, it can be used for grinding and grading raw ore pulp, grading aluminum hydroxide, and rapidly separating red mud.

· Other Applications: It can also be used for grading, separating, concentrating, and dehydrating non-metallic minerals such as kaolin and feldspar, as well as for sand removal and desliming in wastewater treatment.
