Some company is offering me to take a large number of barrels full of
worn out steel shot blast. It is a all steel powder with grains the
size of regular table salt.
I took a sample to a scrap yard and they say that they do not want to
pay for it as there is "no market for this commodity". As I cannot
easily see why this powder cannot be melted, I would like to see if
anyone knows why? What is so bad about used all steel shot blast
This is just my thought. No experience at all.
The used shot probably has rounded surfaces and therefore do not work well for shot blasting.
Melting the shot can be done, but there is a huge surface area. So unless you have a furnace with a controlled atmosphere you will probably end up with a lot of rust particles in the steel.
You might contact a mini steel mill company such as Nucor and see if they can use it. THey use electric furnaces and a controlleed atmosphere. You might have to set up some sort of thing to separate the trash from the steel shot before melting it.
STEEL SHOT RECYCLING
Used steel shot abrasives have value! As a by-product from shot peening and
blasting operations, used "Spent Shot? can be one of the most valu
able items a manufacturer can recycle.
Wisdom works with manufacturers to identify collection points and develop m
ethods to capture these materials that maximize their value.
Shot blasting and peening machines use a combination of air and screens to
clean the shot during operation. As the shot is used, the size of the origi
nal shot is reduced due to wear, resulting in smaller less efficient sizes.
This smaller size shot that is expelled from the process has value!
Many manufacturers feed the smaller sized steel shot material back into the
ir machines in an effort to save monies. However, by doing so, the smaller
shot is further abraded and results in a non-recyclable Shot Dust. These ac
tions make the machines less efficient and create greater amounts of shot d
ust by-products that require landfilling and increased costs.
The Shot Dust created from these operations is very difficult to recycle, i
f only iron based products are being blasted. If your operation uses steel
shot to blast products that contain Ni Alloys, Wisdom will be able to recyc
le the Shot Dust and "Spent Shot ,? saving your company even more m
oney and eliminating another costly waste stream. In addition, if your oper
ation uses Stainless Steel Shot, we can provide a value for these materials

Have a sample assayed and if it is high iron and nothing exotic a farmer
might want to dress his field with it - or you your front yard grass. Grass
uses iron to green with. People don't like it since it rusts. So
fields are best.
