At present, both domestic and foreign companies pay more attention to the research of centrifugal sedimentation machine. The working principle of the centrifugal sedimentation machine and the gravity sedimentation machine are different. During gravity precipitation, the ore particles are subjected to gravity and settle at almost constant speed, while the centrifugal sedimentation machine is subjected to centrifugal force. The magnitude of the centrifugal force experienced when the ore is rotated is calculated as follows:

MÏ… t 2 GÏ… t 2
C = ———— = —————
r gr

Where G is the effective weight of the ore (ie the weight of the ore in the air minus the weight of the body), in kilograms;
r - radius of gyration, meters;
Ï… - rotary peripheral speed, m / s;
9 - Gravity acceleration, m / s 2 .

2 πrn Gυ t 2
Because υt = ———, substituting its value into υ t = ———, the centrifugal force is:

60 gr

Grn 2
Therefore, C ≈ ———, cattle 900

It can be seen from the above formula that for a certain weight of ore particles, the centrifugal force increases as the radius of gyration and the number of revolutions increase. The ratio of centrifugal acceleration to gravitational acceleration is usually used to indicate the operating characteristics of the centrifugal sedimentation machine. This ratio is called the centrifugal separation factor K and its value is equal to

Ï… t 2 rn 2
K = —— = ———
Gr 900

The larger the separation factor, the stronger the centrifugal force, and the easier it is to precipitate the ore. Therefore, increasing the speed and radius of the centrifuge can achieve this goal.
The biggest advantage of the centrifugal sedimentation machine is that it can effectively treat the precipitation of fine-grained slurry. For micro-fine pulp precipitation, gravity sedimentation tank or thickener, painstaking mine pull settling rate is very small, very slow process of sedimentation, flooding often take away a lot of fine mud, resulting in the loss of metal Moreover, the concentration of the precipitate is low, the concentration effect is poor, the productivity per unit area of ​​the equipment is low, and the floor space is large. The centrifugal sedimentation machine can just overcome the above shortcomings, and the effect of sedimentation and concentration of fine mud slurry is more significant. Therefore, the centrifugal sedimentation machine is a relatively promising dewatering equipment . However, compared with gravity sedimentation equipment, centrifuges consume more power, the equipment structure is more complicated, and management and maintenance are not as simple as gravity equipment.
