Focus On: Centrifuges from Freddy

The alternative to paper-band filtering

The Concept

An open topped rotor is driven at high speed, into this is fitted a long-life removable flexible rotor liner, shaped to the inner contour of the rotor.

The rotor liner is secured to the rotor by a removable vane assembly, consisting of a ring and four vertical vanes.  Dirty coolant is fed into the top of the rotor assembly either by a feed pump or by gravity, and is deflected by the centre cone toward the base of the bowl.

Centrifugal force acts upon the dirty coolant, packing the foreign matter into a ‘cake’ against the wall of the rotor liner.

The clarified coolant overflows through the hole in the top of the vane assembly and is returned to the machine tool.

The rotor liner collects foreign matter up to a capacity of approximately 4,000cc (250 cubic inches).  This allows a sludge cake of 9-23kg to be built up, depending on the nature of the foreign matter.
