SIZE OF CUTS
Size of cut is determined by the type of
cutting head and impeller. Cutting heads
and impellers come in a variety of types
and sizes to produce particle sizes from
fine to coarse. The nature of the product
will also affect the size of cut. Consult
Urschel Laboratories for the cutting head
and impeller combination best suited to a
particular application. See pages 65 & 67
for a complete list of cutting heads.
Impellers are listed with the cutting assem-
bly on page 63.
CUTTING HEAD DESCRIPTION
The cutting head is a ring of vertical
knives and horizontal separators in a rigid,
one piece unit (Figure 14). Cutting heads
are identified by the Urschel 5-digit part
number and a corresponding description
number. The description number indicates
the height of the head (3"), the pattern and
number of columns, the openings between
and thickness of horizontal separators, and
the material of construction. See page 44
for more detailed information.
Cutting heads are available in two differ-
ent styles, each made by a different
method: Urschalloy cutting heads are cast
from one of the toughest and most wear
resistant alloys; fabricated cutting heads
are made of individual pieces of a tough
special alloy stainless steel, assembled and
silver brazed together. Each style of cutting
head is available in several different types
(Figure 15, page 21.) The type indicates the
pattern and number of columns, which
contain the cutting edges. Fewer columns
will produce a thicker particle.
