Hydrocyclone is a common separation and classification equipment, commonly used in centrifugal sedimentation principle. When the two-phase mixture to be separated enters the cyclone tangentially from the hydrocyclone periphery with certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Due to the particle size difference between coarse and fine particles, they are subject to different sizes of centrifugal force, centripetal buoyancy, fluid traction, etc., and are subject to centrifugal sedimentation, most of the coarse particles are discharged through the bottom flow port of the cyclone, while most of the fine particles are discharged from the overflow pipe, thus achieving the purpose of separation and classification.First of all, we would like to introduce the classification of hydrocyclone. The hydrocyclone is divided into classification hydrocyclone, dewatering hydrocyclone, desilter hydrocyclone, slagging hydrocyclone, thickening hydrocyclone, tailing dry discharge hydrocyclone.
Dewatering hydrocyclone is mainly used for the dewatering operation of various mineral slurries. According to different material characteristics, different production and installation environment, different structure design is adopted, which has the advantages of lower pressure, large processing capacity and high dewatering efficiency. It has the advantages of lower pressure, larger capacity and higher dewatering efficiency. In the dewatering operation of a tailing re-election slurry, the hydrocyclone is used in a concentration of 5-12% of the feed ore and 75% of the -200 mesh content. The average concentration of the overflow of the hydrocyclone is controlled below 1.5% under the condition of 75% of the feed ore concentration and -200 mesh content, which can achieve effective dewatering and avoid useful dewatering. In the dewatering operation of a silica sand, the average concentration of the hydrocyclone overflow is controlled to less than 1.5%, which can achieve effective dewatering and avoid the loss of useful minerals. In a silica sand dewatering application, the overflow concentration of the dewatering hydrocyclone reached 1.5% or less. In a silica sand dewatering operation, the overflow concentration of the dewatering hydrocyclone reaches less than 0.5%, and the overflow is almost unqualified fine mud, achieving the dual effect of dewatering and mud removal. The hydrocyclone overflow water is settled and reused to save cost.
High efficiency desliming hydrocyclone is mainly used for the desliming operation of various metal ore and non-metal ore slurry. High efficiency desilter hydrocyclone. On the basis of absorbing the excellent achievements from abroad, after several years of practice, we have determined the ratio and coordination of the main components of the high efficiency desliming cyclone. The high efficiency desilter hydrocyclone is designed and produced with high efficiency of desilter, low loss of useful minerals and cost saving for users. The design and production of high-efficiency desilter hydrocyclone has the advantages of high desilter efficiency, low loss of useful minerals, saving cost for users and improving production efficiency. Case: A silica sand mine discarded tailings The muddy minerals of a silica sand mine account for 12.7%, and the fineness of -325 mesh accounts for 39.3%, and almost all the muddy minerals are stored in -325 mesh grade.
High efficiency thickening hydrocyclone is often used in conjunction with thickener, filter, etc. It is applied to various minerals before filtration concentration, mineral fine grinding flotation, gold pulp cyanidation and other preparatory operations before the concentration, as well as the tailings of high concentration of tailings, etc.

High efficiency thickening hydrocyclone is seldom used alone, but often used in combination with other equipment. Thickening hydrocyclone can be adjusted in terms of structure and installation according to customer requirements and the specific conditions of upstream and downstream operations to achieve the most optimal use effect, while the hydrocyclone can produce a higher bottom flow concentration with a lower overflow concentration by using the unique internal structure design to improve productivity, reduce expenses and save costs.
High efficiency thickening hydrocyclone is the core of the tailings dry discharge system, high efficiency thickening hydrocyclone, thickener and dewatering screen.The combination of high efficiency thickener hydrocyclone with thickener and dewatering screen can complete the thickening and dewatering process efficiently.
Hydrocyclone are commonly used as classification equipment in industrial enterprises with mineral processing links. Hydrocyclone are mostly used for classification, sorting, thickening and desliming of ore slurry in these enterprises. When hydrocyclone is used as classification equipment, it is mainly used with desilter, desander, mud cleaner. When used as classification equipment, cyclones are mainly used with mills to form a grinding and classification system. In addition, hydrocyclones are mostly used for desilter in re-election plants and dewatering in tailings treatment.
The advantage of the hydrocyclone is that it has no internal moving parts, so the structure is simple and easy to use. Compared with Compared with other classifying and separating equipment, the classification efficiency is higher, which can reach more than 80%, and the hydrocyclone classifies. The particle size of cyclone classification is fine, which can meet the requirements of industrial production. In addition, the low cost and low material consumption of cyclone more economic value.
