A hydrocyclone by an upper hollow cylinder, the lower part of a cylinder in communication with the inverted vertebrae, both consisting of hydrocyclones operating cylinder. In addition, there hydrocyclone to mine management, overflow pipe, overflow pipe and Spigot.
Used sand pump hydrocyclone (or height) to a certain pressure (typically 0.5 to 2.5 kg / cm) and flow rate (about 5 to 12 m / sec) the pulp in a tangential direction screwed into the cylinder, and then the slurry will be in a very fast rotation along the tube wall to generate a centrifugal force. By centrifugal force and gravity, the thicker, heavier mineral particles thrown.
Hydrocyclone beneficiation industry is mainly used in grading, sorting, concentration and mud off. When the hydrocyclone is used as grading equipment, mainly used to compose and mill grinding and classification system; when used as Desliming equipment, can be used for re-election plant Desliming; used as a dewatering device, it can be used to beneficiation tailings After concentrating sent to fill underground mining tunnel.
Hydrocyclone no moving parts, simple structure; greater production capacity per unit volume, accounting for a small area; high grade efficiency (up to 80% to 90%), small size grading; low cost, less material consumption.
The suspension at high speed by the feed tube in a tangential direction into the hydrocyclone, due to restrictions of the outer cylinder wall, forcing the liquid rotary motion from top to bottom, this movement usually called outer swirl or fall swirling motion. The outer cyclone the solid particles by centrifugal force, if the density is greater than the density of the surrounding liquid (which is in most cases), which suffered greater the centrifugal force, once the force is greater than the fluid resistance generated due to movement of the solid particles are will overcome this resistance and move towards the direction of the wall separating the suspension, reach the wall near the particles are subjected to continuous liquid driven downward movement along the wall to reach the vicinity of the bottom orifice gathered become greatly thickened suspension from underflow discharge port. Purified liquid separation (of course, there are some small particles) continues to rotate downward movement into the conical section, because the inner diameter of a spin liquid separator is gradually reduced, the liquid rotational speed. Since the liquid generated when the swirling motion in the radial direction of the uneven pressure distribution, the smaller the closer to the axis while the axis at close to zero, a low pressure vacuum zone and even zone, resulting in a liquid tends to move in the axial direction. Meanwhile, since the hydrocyclone underflow outlet greatly reduced, the liquid can not be rapidly discharged from the bottom orifice and the center of the vortex chamber overflow the top cover, since the portion of the liquid leaving the low pressure region in which to move, thereby forming an upward rotational movement and discharged from the overflow.
