【Description】 Hydrocyclone is used for separating and removing heavy mud and sand of coarse particles and sometimes for dehydration of slurry. The Hydrocyclone separator has two types of pressure type and gravity type made up of either cylindrical structure or metal pipe. Water is fed through the top of the structure (or metal pipe) by means of pressure or gravity along the tangent line. Coarse and thick particulate matters are thrown to the wall, rotated down and discharged together with the concentrated liquid formed under the action of centrifugal force. Small particulate matters are discharged together with secondary upward vortex after rotated to some extent.
Hydrocyclone/ cyclone filter is mainly used for classification, separation, concentration and desliming in the mineral mining industry. When the hydrocyclone is used as a classifier, it is mainly used to form a grinding and classification system with a mill; when it is used as a deslimer, it can be used for desliming in a gravity concentrator; when it is used as a concentrating and dewatering device, it can be used to concentrate ore dressing tailings and send them to fill underground mining tunnels. The hydrocyclone sand separator has no moving parts, simple structure, large capacity per unit volume, small area, high classification efficiency (up to 80% ~ 90%), fine classification granularity, low cost and low material consumption.

【Hydrocyclone Working Principle】The hydrocyclone consists of a hollow cylinder at the top and an inverted cone at the bottom, which is connected to the cylinder to form the hydrocyclone. In addition, the hydrocyclone also has feed pipes, overflow pipes, overflow conduits and sinks. The hydrocyclone pump (or height difference) rotates the slurry into the cylinder along the Tangent Direction with a certain pressure (generally 0.5 ~ 2.5 kg/cm) and flow rate (about 5 ~ 12 m / s) , and then the slurry rotates along the cylinder wall at a very fast speed to create centrifugal force. Under the action of Centrifugal Force and gravity, the coarse and heavy ore particles are thrown out.
The suspension enters the hydrocyclone at a relatively high speed from the feed tube in a tangential direction and rotates from top to bottom. This motion is commonly referred to as external or descending swirl motion. The solid particles in the external swirl flow are separated from the suspension by Centrifugal Force and move down the wall of the device to discharge from the bottom outlet.
