Am I correct in assuming you are not using a compressed air cylinder to move the

flap gate back and forth to divert the incoming flow from one side to the other

side of the stck pile?

over here anyway the cylonders are used to simply move the flap gate back and forth and

come to a stop to allow an even draw on both sides of the stock pile as the coal is minus2 inches anyway. ■
