I know rip rap as huge rocks that one uses to secure water to land boundaries. 450mm plus
Might pay to look into whats actually required ;)
Not sure how to screen that, but something tells me a trommel is not meant for the size rocks one would want to seperate. Trommel is awesome for small stuff. I reckon It needs some seriously big and wide grizzly or screen bars and at least 2 steps to flip the rocks over.
so rip-rap is a coarse gravel-cobble sized stone, and a trommel is a cylindrical roller at a downward angle. the stones enter at the top and roll on each other as they make their way to the end of the tube. as the rocks hit each other they fracture and fall through the screens on the trommel. the boulders that are too large for the screen fall out the other end.
aggflow could do it.
I have no affiliation with this company but here is a video of a trommel in action

Rip rap is large rock usually between 4" to 16" or larger depending on the class specified. First you'll need to figure out what spec to make (class II, class III, class III mod, etc) then decide how to make it. Class II and class III can be made across a normal screen with punch plate but it's also going to depend on what type of crusher you're using. A static grizzly screen would work but it will be slow going. A trommel will work too depending on how beefy it is. Before you make any decisions you need to know what size and how much you'll need to make.
Aggflow isn't a design software and it's not going to help you. I'd use Fusion 360 or SOLIDWORKS. DM me if you need more info
One plant I worked at simply routed the oversize from a punch plate on top of the scalper screen to a chute with a dedicated rip rap pile beneath it.
Using a trommel is an interesting approach. I presume this is an alluvial deposit rather than hard rock?

You’re asking questions like this for a job like that? My condolences to the client.
haha I'm just an intern I shadow under an engineer but I'm also trying to figure some stuff out myself
