Hydrocyclone

What’s a Hydrocyclone?

The hydrocyclone is grading equipment that uses centrifugal force to accelerate the sedimentation of ore particles. It is mostly used for grading operations in the second stage of closed-circuit grinding, and is sometimes used for mud dehydration to obtain very fine overflow products. We can also customize multiple hydrocyclones to form a group to improve classification efficiency.

Working Principle Of hydrocyclone

The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container.
The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds of times greater than gravity) . Under the action of centrifugal force, the coarser particles are thrown toward the wall of the vessel and move downwards with a spiral track, which is discharged from the grit nozzle to become coarse-grained products; the finer particles and most of the water are in the spiral path, discharge from the flow tube.

Advantages Of hydrocyclone

• Hydrocyclones can adapt to liquids of different flow rates and particle sizes, effectively remove fine solid particles, and help remove suspended solids, sediment or other solid impurities.
• With no moving parts, maintenance costs are relatively low
• Compact design, takes up relatively little space and is easy to operate
• Hydrocyclone performance can be optimized by adjusting the feed flow rate, feed concentration, and cyclone geometric parameters to meet the requirements of different applications.

Structure

The hydrocyclone mainly consists of a cylindrical part, a cone, an inlet pipe, an overflow pipe and a bottom flow opening. The inlet pipe is tangentially connected to the cylindrical part to spin the slurry in and generate centrifugal force. The bottom flow opening at the bottom of the cone discharges coarse and heavy ore particles, while the overflow pipe at the top of the cylinder discharges fine and light particles. This structure allows the hydrocyclone to effectively classify the slurry.
