- The Falex Miller Number Slurry Abrasivity Test
Machine can be used to develop data from which either the relative abrasivity of
any slurry (Miller Number), or the response of different materials to the
abrasivity of different slurries (SAR Number), can be determined. It meets the
requirements of ASTM G75, "Test Method for Determination of Slurry Abrasivity
(Miller Number) and Slurry Abrasion Response of Materials (SAR Number)."
-
- The "Miller Number" is an index of the relative
abrasivity of slurries. Its primary purpose is to rank the abrasivity of
slurries in terms of the wear of a standard reference material. The wear damage
on the standard wear block is worse as the Miller Number gets higher. The SAR
Number is an index of the relative abrasion response of materials as tested in
any particular slurry of interest. The SAR Number is a generalised form of the
Miller Number applicable to materials other than the reference material used for
the Miller Number determination. A major purpose is to rank construction
materials for use in a system for pumping a particular slurry. It can also be
used to rank the abrasivity of various slurries against any selected
construction material other than the reference material specified for a Miller
Number determination.
-
- The relative effect of slurry abrasivity in both
the Miller Number and the SAR Number is determined by using the measured mass
loss of a standard, shaped metal block, driven in a reciprocating motion by a
rotating crank, riding in the bottom of a tray containing the slurry. A direct
load is applied to the block. For each test, the bottom of the tray is equipped
with a new piece of a sheet of Neoprene to act as a lap. The interior of the
tray has a flat bottomed or truncated "V" shape formed by the filler, that
confines the slurry particles to the path taken by the wear block. At one end of
each stroke, the block is lifted off the lap by a cam action for sufficient time
to allow fresh slurry material to
- flow under the block. The block holder is made of
plastic, as are the trays, so that electrolysis inherent in certain slurries is
minimised.
