Cooler Grte

Hi

Suggest checking your PLC control

The speed of the grate should be in a table - increase feed rate and speed increases...

I think that you may also have a under grate pressure control as well...second loop - if the bed builds up..the back pressure increases and grate speed increases acc.

Pls check your PLC vs the OEM supplier commissioing set up.

The other option is that youyr grate is slowing down with the increased load...but you should have an underspeed detection set up for this and this is then a hydraulic/mechanical issue

Thanks
