bosse , the dome witch I call a bubble is verry convenient for weather conditions.I personally would've double the size for a 2 day bed.This dome gives you a steady state of feed or a steady feed rate.This also gives you invetory as if something goes wrong with the crusher a loader can go in and feed the conveyor belt that goes to the sag mill from the dome.Definetly needed.I 'm anxious for Bell Creek resource update as I feel will be good. GLTAL p.s. rewarded verry much so .
