Blending The Compound






Category: HEAT TREATMENT OF STEEL

Essentially, this consists of the sturdy, power-driven separator
and fanning mill which separates the foreign matter from the compound
and elevates it into a large settling basin which is formed by
the top of the steel housing that incloses the apparatus. After
reaching the settling basin, the compound falls by gravity into
a power-driven rotary mixing tub which is directly beneath the
settling basin. Here the blending is done by mixing the proper
amount of various grades of material together. After blending the
compound, it is ready to be stored in labeled containers and delivered
to the packing room.

It will be seen that by this simple system there is the least possible
loss of energy from the compound. The saving commences the moment
the cooling cart is covered and preserves the valuable dust which is
saved by the oiling and the settling basin of the blending machine.

Then, too, there is the added convenience of the packers who have
a thoroughly cleaned, dustless, and standardized product to work
with. Of course, this also tends to insure uniformity in the
case-hardening operation.

With this outfit, one man cleans and blends as much compound in
one hour as he formerly did in ten.
