Building No 36: Tetryl Mixing
|
|
The
Tetryl Mixing building is used merely for the blending of Tetryl.
For certain pellets, Tetryl must be mixed with a small amount
of graphite. The building is heavily barricaded and air conditioned.
The small building at the left contains the air conditioning.

view of the Tetryl Mixing building showing the mixing barrel which
is operated by an explosion proof motor. This motor is controlled
by a switch 100 feet or more from the building. The charge is
placed in the mixer, then the operator goes out, locks the door
to the building and then walks to the switch, which is beyond
the barricade and turns it on to start the mixer. The mixer is
never run with anyone inside the building.

The Tetryl Storage
Magazine, Building No 25, was used for the storage of Crystaline
Tetryl used in stemming and the granulated Tetryl used in the
making of pellets and loading the exploder bags. Like all magazines,
it was heavily barricaded.
