VSI Benefits. When it comes to producing materials such as aggregate for road making, VSI crushers use a high-speed rotor and anvils for impact crushing rather than compression force for the energy needed for size reduction. In a VSI, material is accelerated by centrifugal force by a rotor against the outer anvil ring, it then fractures and breaks along natural faults throughout the rock or ...

Balancing of Shaft Couplings | RINGFEDER®

Concerning balancing, a distinction is made between "static" balancing (the so-called one-plane balancing) and "dynamic" balancing (the so-called two-plane balancing). The decisive criterion for static or dynamic balancing is the length/diameter ratio of the rotor to be balanced (e.g. the entire coupling or components of a coupling).
