Dear Anupama, For Grab type unloaders we take effective cap. generally 60-65% of the rated capacity.For cont. type unloaders we take this fig. as 80-85%.Now a days in India grab cap. 60-65- tonnes are being used. For 65000 dwt cap. you need to have min. 2 grab type unloaders which can give you max. cap 50-60000 tpd.
Formula to calculate these figures is good on papers because lot of things depends upon site condition.

Effective Handling Capacity of Grab Unloader
