Slag Crushing by The Standard The Standard - standardized crushing and screening plants GmbH Spielbergstrasse 4 4332 Au an der Donau / Austria email: h.stefan@me.com
Up here in Ontario Canada, slag is only allowed in granular products. The chemical composition is too risky and may not be compatible with the bitumen in asphalt or cement in concrete. We have plenty of natural aggregate sources anyway. Some of the quarries have fantastic physical and chemical properties. A loose term “armour stone” is used when you get that stuff.

Dang! Y’all think you can help me find my wedding ring? We’ll just throw my whole house in there and eventually the ring’s bound to turn up. It’ll be worth it, you don’t know my wife 😰😰😰
Not so, once you realize "slag" is mostly (but not exclusively) non-ferrous impurities like silicates, calcium, various minerals, other trace metals, etc. Smelting tech and rapid inexpensive mass spectrometry have advanced enough in recent decades to make recycling profitable as well as environmentally desireable, esp if you consider that there is often more metal present in old slag than there are in various lower grades of ore.
@@gregorymalchuk272 AFAIK it depends. Processing into aggregate for use in concrete or as RCS is probably a simple matter of iterative crushing and sieving to the desired size, whereas recycling for re-smelting is likely much more technically involved - what type of processing is done for the latter depends on lots of factors, including the type and quality of ore/material it came from, the type of smelter that produced it, the types and amounts of impurities present (i.e., phos and/or sulphur, et ), what product was being produced at the time (ex: a blast furnace processing first run ore into pig iron produces different slag than say an Electric Arc Furnace smelting a high alloy from raw materials that were already highly pre-refined and/or recycled). The local demamd/market plays a role as well I imagine. This is all armchair theory for me. Analogy: If life hands you lemons, whether or not you make lemon oil extract, dried lemon zest, lemon juice, lemonade, preserved lemons, food grade citric acid, animal feed, or some subset of all of the above products, depends on a lot of factors ... factors that vary from plant to plant, market to market, and company to company..

My dad said they used slag as fertiliser on the farm in Scotland in the 60's.Said it grew tremendous turnips
Logical recycling of iron smelting waste ---- road base, concrete etc
Used as bedding for railroad tracks also
That slag caused a lot of health problems in the town where I live. Copper refinery has killed a many people around here
i like this video they are crushing the slag
The used to use it on snow when they ran out of salt around here.
that amchineatthe 4.50 mark, put some widder cups on the ends for scooping
Looks like fun! Was the bucket that dumps the slag on track's? How heavy is something like that?
the bucket carries 50 tons
Pity nobody tells you what the different grades of slag is used for!!
that was machine at the 4.50 minute
Scrap gold
can slag be turned into asphalt agregate (filler)
Yes we process slag to make asphalt

What do they do with it after its crushed?
A lot is spread on secondary roads and highways.
it has alot of uses from road repair to driveway fill material and aggregate for large asphalt surfaces to even home landscaping

And how many prosent is there metall left in the slag?😮

keep the house and thro your wife in ;-)

Seems odd to try and crush the metal rather than shred it.

Wait, are they crushing it to be fed back into the smelter or used as aggregate in concrete?
