Grit Feeder 155/255
Three-Body Abrasion Testing
Expand testing methods for Taber Rotary Abrasers.
The Grit Feeder is used to evaluate three body abrasion caused
by the destructive action of fine hard particles. Loose grit passes
under a pair of leather clad brass wheels, and serves as the
abradant. The resulting rolling action of the particles contributes
to the physical breakdown of materials.
Instrument evenly distributes grit particles.
Positioned over a Taber Rotary Abraser, this freestanding unit
deposits aluminum oxide grit particles uniformly and continuously,
at a specified rate. After passing under the leather wheels, used
grit and any abraded material is removed by the Abraser vacuum
system.
Two models offer simple set up.
Mounted off the left side of the Abraser, Model 155 utilizes an
alignment guide screw to set the position of the instrument. Grit
distributor and vacuum removal nozzle heights are adjusted using
a thumbscrew. An alignment block is
incorporated into the base of Model 255,
to ensure the correct location of the grit
feeder in relation to the Abraser. With
the ability to mount on either the right
or left hand side, two instruments can
be used in conjunction with Taber’s
Dual Rotary Abraser. A telescoping
feature allows precise height adjustments,
and permits testing of thicker specimens,
up to 50 mm (2 inches).
