The bowl of a FALCON concentrator consists of a sophistically engineered system of two sections: The conical stratification zone [S]* and the vertical retention zone [R]*. Slurry is accelerated to reach a high centrifugal velocity and stratified along the steep, smooth wall under semi-laminar flow conditions. Stratification and acceleration are effective on the finest particle sizes in the industry. Pulp densities below 50-60% solids by weight are most favourable. The laws of physics (and common sense) dictate that separations become more inhibited as pulp density increases. Although it is possible to treat up to 70% solids by adding fluidizing water and providing a bowl with riffles from top to bottom, this approach introduces turbulence and results in loss of fine target minerals. It is clearly understood that laminar flow characteristics are superior to turbulent for gravity recovery of fines.
...
The machines utilize a VFD (Variable Frequency Drive) to control the bowl speed and centrifugal acceleration. Dynamic braking absorbs the energy of the rotating bowl from run speed to rinse speed, allowing for rapid rinse cycles, shorter offline times or in turn longer online time.

  -> Спасибо, вот тоже посмотрел, что пробирки-фальконы там вроде ни к чему, да и роторы у центрифуг обычно идут в комплекте и частой замены не требуют
