View Full Version : Tons per hour?

Were crushing bridge deck and abutment material...(large concrete)...The primary crusher is a Pioneer 2650 tracked jaw crusher feeding directly into a Kpi Jci 4240....Final product is 2'" and under.....What do you fellas feel is a realistic TPH? Its tough because I'm loading it and typically stop about 4 times a day for 5 minutes each time..Usually to get rebar out of the mag or to reverse the jaw if it becomes plugged...Just wondering what YOU would feel is good production.....Were down right now because the jaw blew apart 3 weeks ago,,,,Replaced parts and now the toggle plate BROKE IN HALF!!!!! We think it was stressed from the first from the first time it broke and finally let go 2 days ago.....Steve

lmao, never mind what I had wrote there, haha. Totally missed what you said. Rebar and jaw crushers don't mix at all. Hard to say what the tph would be, since you may go one day and stop a dozen times removing junk, but may get in a good batch and may only have to stop 2-3 times a day. I'd say it's going to be fluctuating a lot.

I'll go out on a limb here and say about 250 ton per hour, on a good day.
I also agree that rebar and jaws do not agree. I feel you are better off with a impactor in rebar infested concrete.

Well I know according to the scale, we hit 300 - 400 tph....But after stopping tose few times , it averages to 125 tph.....You dont make any money THAT way! Its a new scale and I;m not sold that its 100% correct...We still plan on loading a 10 wheeler to the scales 20 ton .....Then weigh the truck just to be sure.Steve

to justify the operating costs of both those machines, you need to be well above 250 tph, fairly consistently.

I remember seeing a picture of a road gravel crushing job years ago that had THREE belt scales in a row on the discharge conveyor... one belonged to the crusher owner, one belonged to the county/customer, and one belonged to the landowner who was furnishing the raw material... I don't know if they averaged them, or what... but, for sure, nobody had much confidence in the other guys scales.
