A boulder too big for the crusher mouth going in anyway
Early morning at the primary crusher. The apron feeder brings material down from above and, among the gravel, three boulders the size of an oil drum come with it. One is already entering the machine’s mouth and it is wider than the gap in front of it. Dust hangs below and the outfeed belt keeps moving fines. The beacon on the control panel is lit. IRIS measures the boulder against the width of the mouth.

What this camera measures
An alert says something is happening. The reading says how much.
- 07:52Time it went in

The figures on this screen are an example from the illustration, not any client's measurement.
The rule
You decide once. IRIS applies it always.
If
material wider than the crusher mouth enters
Then
- alert the panel operator with the camera, the time and the measured size
- save the video of the boulder from the moment it appears on the feeder
- add the boulder to the shift tally of oversize pieces
The instruction that set it up«Tell me if a rock wider than the crusher mouth is coming down the feeder.»
What changes
What changes for whoever answers for the plant
An oversize boulder jams the mouth, and clearing a primary crusher means half a day, a crane and people working on top of the machine. With the camera, the panel operator knows while the boulder is still on the feeder: there is time to stop the feed before it goes in. And if it goes in anyway, the video and the time remain, which is what lets you find out which blast or which bench that material came from.
What people usually ask
How does IRIS measure the size of a rock?
Against a physical reference that is in the picture itself. The crusher mouth, the width of the feeder and the roller pitch have known dimensions and they do not move. IRIS compares the rock with that reference and gives a width. This is not a guess or an abstract calculation: it is a measurement against a fixed part of the equipment, which is why it can be repeated and audited.
Does it also catch material that should not be there, not only big boulders?
Yes, if it can be seen. A piece of drill steel, a tyre, a length of hose or a drum among the rock stands out clearly by shape and colour, and that is the kind of thing that breaks a jaw. What the camera cannot see is what is hidden inside a boulder or mixed into the fines. That is what the metal detector and the screen are for, and the camera works beside them, not instead of them.
Does IRIS stop the feeder when it sees a boulder like that?
No. IRIS alerts; stopping the machine is a person’s decision or the plant control system’s job, not the camera’s. The alert reaches the panel with the image and the measured width, and there the operator decides whether to cut the feed, pull the boulder out or let it through because it will pass edge-on. IRIS does not replace the plant control: it works beside it and adds the picture and the exact minute.

Next step
Who watches an entire motorway?
10 cases: 8 raise an alert when something happens and 2 only measure. You see each image as it is, and then with what IRIS understands on top.
Who watches a whole station at rush hour?
17 cases: 11 raise an alert when something happens and 6 only measure. You see each image as it is, and then with what IRIS understands on top.
And the best part
A recording gets watched when nothing can be done.An alert lands while there is still time to act.
IRIS raises the alert while it is happening and says where: the camera, the time and the images from that moment. With that, whoever is on duty is still in time to act.
