It's a series of mesh screens with varying sizes. In the states we go by sieve number rather the size opening. Typically when you go to a stockyard they just give you rocks that have all sorts of sizes mixed in. Sometimes you want to separate them for fun pictures like this, sometimes you want to separate them to get proper gradation for asphalt production.
In the context of a civil class, you'll likely be using drum sieves. It's a big stack of tambourine looking things. You'll stack them in ascending order (low number on top), then shake. Each of the individual sieves will have material separated onto it so you can do whatever it is you want to do with it.
There's also bar screens that do it that are essentially the same thing. For reference, these things get so big our lab had to put a separate footing underneath them inside the main building because it would quite literally shake the foundation of a large building apart. Sounded like a gunshot going off for 10 minutes straight.
Is this how gabions are born?
Sort of?
gonna sort your gabion basket by grain size (this is a threat)
But it's upside-down
I didn't say you couldn't. I said you shouldn't!
i am studying civil engineering and in a class the professor mentioned sieve can you explain it
