| The
FS/HD/PM series of hogs are based on the original patented punch-and-die design
that was invented by W.T.S. Montgomery in the late 1940’s as a superior method
of processing scrap. |
| |
| This series offers a complete line-up in both gravity and
horizontal feed configurations with your choice of gravity, pneumatic air pickup
or integral fan discharge options. |

PUNCH AND DIE CUTTING
All FS, HD and PM HOGS employ a unique cutting action involving stationary
anvils positioned on the side of the machine with rotating teeth (hammers) that
pass through rectangular pockets formed by these anvils.
|
|
|
|
This positive cutting action between the teeth and anvils performs what
amounts to the first particle-sizing function in a two stage process.
|
|
The second sizing action occurs when the material cut by the action of the
teeth against the anvils is directed downward and across a curved
particle-sizing screen which fits underneath the rotating element.
|
|
|
| The screen is used to control the size of the material discharged from the
unit. The smaller the openings in the screen, the smaller the end product will
be.
|
| |
| The discharge from Montgomery Hogs is generally quite uniform in size,
containing a minimum of fines.

TRAMP METAL PROTECTION
Shear pins are used to protect the HOG from tramp steel. Each breaker
ring is secured and held in position on the shaft by three shear pins. The
shearing strength of these pins is sufficient to carry loads encountered in
normal operation of the HOG but will shear when heavy tramp steel enters the
HOG. This configuration lets the ring stop while the shaft continues to
turn.
|
|
|
| A plastic cylinder of oil is inserted in each ring in the first hole behind
the tooth to provide lubrication should these shear pins shear.
