We all know that the classification of cheapest hydrocyclone products is based on the principle of centrifugal sedimentation, and the working principle of desliming is also similar. Due to the different particle sizes and densities of fine slime and coarse sand, the centrifugal force they receive is also different. When the ore-bearing slime slurry enters the feeding pipe by pressure or gravity, and enters along the tangential direction, the centrifugal force on the coarse sand is large, and it will It is thrown near the wall of the vessel, and is discharged from the sand settling port at the bottom with the outer spiral flow, becoming an underflow product with more solid particles; while the sludge is less dense, the centrifugal force received is correspondingly smaller, the settling speed is slow, and it stays In the spiral flow for a long time, it eventually becomes the overflow product.

Usually, when cheapest hydrocyclone products is used for desliming, it is mainly used in the gravity separation plant, or the desliming of the chemical plant.​​
According to incomplete statistics, the first 50% of the final tailings sludge in the concentrator is discharged by cheapest hydrocyclone products. After continuous experiments and practice in recent years, it is technically and economically feasible and reasonable to use cheapest hydrocyclone products to remove the sludge in the pulp. It has many advantages: first, the beneficiation process is optimized. The process improves the classification efficiency of desliming, plays a certain role in protecting the equipment in the subsequent beneficiation process, and improves the service life of the beneficiation equipment.​​
On the whole, cheapest hydrocyclone products is used for desliming operation, which improves the recovery rate of beneficiation, especially the recovery rate of sludge separation, reduces the beneficiation cost, and increases economic benefits.
