C. at the end of being homogenized, screw conveyor, outer circulation bucket elevator, outlet valve and inlet valve are closed, opens homogenizing storehouse and discharging
Outlet valve, discharging device, screening bucket elevator and screening machine between device, sieve material；
D. the inlet valve of another homogenizing storehouse is opened, a-c operation is repeated, is finished to the matter homogenizing in all homogenizing storehouses, screening
Afterwards, all devices are closed.
