Slurry
can be really tough on pumps! Being thick, abrasive & with
high specific gravity,
slurry is one of the most challenging fluids to move.
What
is slurry?
Slurry
is a mixture of solids and liquid, generally water. The particles can
be both abrasive & non abrasive, although abrasive particles are
very much common. The purpose to move slurry can be transporting as
much solids particles as possible, hydraulically, along with the
given liquid.
Factors
to be Considered in Slurry Pumping
• Particle
size- d85= 3mm- means 85% of particles have a diameter of 3 mm or
less.
• Specific
gravity of solids particles (SGs)
• Specific
gravity of liquid (normally water which is 1)
• Concentration
of solids by volume (Cv)
• Concentration
of solids by weight (Cm) (where Cv, Cm is given in % it means it is
for slurry)
• Specific
gravity of slurry (SGsl)
• Mass
fraction (% of particles below 75 μm)
• Shape
of particles (Round or Flat)
Characteristics
of Slurry
1.
Non – Settling Slurry - In this particle size is less than 60-100
μm. A non settling slurry can be defined as a Homogenous Mixture. It
is comparatively easy to pump non-settling slurry.
2.
Settling Slurry- In this particle size is greater than 100μm.
Settling slurry can be defined as Pseudo-Homogenous Mixture OR
Heterogeneous Mixture. This is where the demand on slurry pumps
increase.
• Steel
Plant- Pumps for mill scale transportation.
• Thermal
Power Plants- Pumps for fly Ash slurry handling.
• Hydel
Plants & projects- Pump for removing silt and sediment from
tailing dams, trenches, channels, Dam gallery, coolant sumps, etc…
• Mineral
Processing Units.
• Mines
& Quarries
• Various
industrial uses like E.T.P, Cement plants, Fertilizer &
Pharmaceutical Plants.
• Sand
dredging, washing and cleaning.
• Lagoon
cleaning & dredging near dockyard and ports.
