 The
TABER® Multi-Media Abraser is available as a separate
attachment or pre-mounted on a single or dual Taber Abraser.
The
medium to be tested is placed in a specimen-testing dish that contains
a stainless steel wear disc. As the dish rotates, an integral drive
shaft operates a set of gears and turns the spline shaft. At the
base of the shaft is a pin holder with three (3) hi-grade brass
pins that rotate in the opposite direction of the specimen dish.
As the powder, fluid or semi-solid flows between the brass pins
and stainless steel, the material acts as an abrasive and causes
wear. Measuring the weight loss of the brass pins provides an accurate
comparison of abrasion rates of different media.
 To
test a wide range of material viscosities, both load and pin holder
speed are adjustable. The standard testing load on the brass pins
can be varied from 250g to 1,000g (in 250g increments). Optional
weight discs can bring the maximum load to 2,500g. The speed of
the specimen-testing dish is dependent on the model Taber Abraser
that is being used - either 60 rpm with 230V models or 72 rpm with
115V models. By changing the gearing, the speed of the pin holder
can be altered.

Using
the template provided, custom pins or wear discs can also be fabricated.
Substituting materials in your specific application will help you
to understand the wear characteristics.
