METHOD AND APPARATUS FOR MEASURING POWDER

摘要

PURPOSE: A powder measuring method and apparatus are provided to reduce the number or time of measuring powder when measuring the target measuring value of powder within a tolerance. CONSTITUTION: A powder measuring apparatus comprises powder discharge units(A0~An), a balance, and a controller. The balance measures the amount of powder discharged from the powder discharge units. The controller controls the operation of the powder discharge units based on the values measured by the balance. The controller compares the largest set discharge amount of the powder discharge units with the target measuring amount and controls the powder discharge unit having the largest set discharge amount to discharge powder once.
