Cyclones/Hydro-Cyclones
Cyclones can be used to process minerals and slurries such
as:
- De-watering-(efficiently to about 50% solids)
- De-sliming - (clays from sand)
- Washing - Lignite from sand
- De-gritting – (sands from clays)
The hydro cyclone uses centrifugal force to separate solids
from liquid or to classify coarser or greater mass particles from finer
or lesser mass solids. This force is generated by converting the delivery
head of slurry (By pump or gravity) at the inlet volute into a spiralling
passage through the cyclone.
This centrifugal action effectively imparts a force to the
solid particles many hundreds of times greater than gravity.
The force encourages solids to migrate outwards to the shell
of the cylinder and once the conical section is reached, downward to the
apex discharge.
The majority of the liquid and very fine or lighter particles
are drawn to the middle where the centrifugal effect is less and are forced
upwards to the overflow via the vortex finder. Thus the cyclone can be
used not only to de-water a slurry but also to classify or wash solids.
The MEP range of cyclones is comprehensive with sizes from
200mm to 750mm. Most major cyclone components are manufactured using mild
steel shells, with a few items from cast iron or aluminium. Linings include:
- Hot Vulcanised rubber liners
- Polyurethane
- Ceramic One Piece Liners
- Ceramic Tiling
Ancillary items include radial and In Line manifolds together
with chutes and collectors.
