Abstract:
A method for feeding a pulverized material, comprising:feeding a separation chamber with said pulverized material from a first storage container; feeding alternately a second storage container from said separation chamber, according to a predetermined storage amount of said pulverized material in said second storage container; continuously discharging said pulverized material from said second storage container while controlling a vacuum effect in said second storage container during said discharging step; and, calculating the amount of said pulverized material in said second storage container, by determining the amount filled-up or emptied-out from the second storage container when the amount of pulverized material is not at a level or weight previously determined, wherein said calculating step includes:calculating the weight variation over a period of time of the pulverized material that is detected in said second storage container for alternately opening or closing the separation chamber for the continuous filling of the second storage container based on the weight of material detected in said second storage container; and, alternately opening or closing said separation chamber, according to the weight of pulverized material in said second storage container.
