Abstract
An improved suspension apparatus and method for damping vibration arising in liquid vortex mixers of the type pivotably supporting a mixing frame assembly and suspending the assembly by at least one spring for mixing a liquid coating using both spin and orbital rotational movements. A pivoting support is located between the mixing frame assembly and a base. A damper in the form of an annular ring is used to damp pivoting movement of the mixing frame assembly. Various pivoting mounts may be used to pivotably support the mixing frame on a base. A bushing provides accommodation of a misaligned spring mounting end turn using a V-groove to retain the spring mounting end turn, and may include an eccentric feature to allow adjustment of the spring mounting length.
