Primary Jaw Crusher Throughput (1 reply)

Hi everyone,

I need to find the throughput (in tph) of a primary jaw crusher that is fed by a Grizzly screen O/S. There is a throughput recorded for the grizzly screen feeding belt but how can I find the cutpoint of the grizzly screen? Would it be best to model it? Or could I use the sample data of the end products to back track to the grizzly screen?

You start asking about the crusher throughput, and then talk about the grizzly cut point. Are you looking for the cut point of the screen in size or tonnage?  For the size measure the opening size and then take approximately 75-80% of that  size.  Say the opening is 300 mm wide, then an approximate cut point would be about 225 mm.  For tonnage it is difficult to measure accurately, but gneral sizing information is fairly accurate if you know the crusher settings and the hardness of the rock.
