MICROPOWDER CHARGING APPARATUS USING PRESSURE DIFFERENCE

摘要

PURPOSE: A fine powder charging apparatus which uses air pressure differential in order to stably charge the predetermined amount of powder is provided to stably charge fine powder inside a container within error range after preventing minute powder within a working space. CONSTITUTION: A vibration generating apparatus is installed within one side of a pressure generating apparatus. A rod cell and a charging container holder(28) are installed within the pressure generating apparatus. A supply hopper(60) is located in the upper side and is settled in the charging container on the charging container holder. An agitating blade(63) revolves a working motor within the supply hopper and the minute powder. The vacuum generation apparatus is installed at the pressure reduction box. The fine powder is filled with the air pressure differential within the pressure reduction box.
