Abstract
The utility model provides a balancer and a centrifuge provided therewith. The balancer comprises annular cavities surrounding outer peripheries of rotors and balls which are arranged in the annular cavities, capable of rolling and provided with multiple diameters. By fixing the annular cavities at the outer peripheries of the rotors and putting the balls of different diameters and different mass into the annular cavities, the balls of lower mass rapidly roll to compensate amount of unbalance as quickly as possible due to small inertia thereof in the case of small amount of unbalance of the rotors. The balls of higher mass, because of larger inertia, can satisfy the demand for amount of unbalance of the rotors in the case of large amount of unbalance of the rotors. Therefore, vibration of the rotors is reduced to prolong service lifetime of the rotors.
