Image Number 10 for United States Patent #6951141.
A method of measuring material in which the material is conveyed by a conveying unit and dropped from a discharge portion of the conveying unit to be supplied into a measuring unit arranged under the discharge portion, and is measured by the measuring unit, includes a first supplying step of supplying the material through the discharge portion into the measuring unit until a quantity of the material measured by the measuring unit reaches a preparatory target value which is small compared to a final measuring target value of the material, and a second supplying step of receiving a portion of the material to be supplied through the discharge portion into the measuring unit on the way to where the material is dropped for recovery, whereby the material is supplied through the discharge portion into the measuring unit at a supplying rate that is smaller than that in the first supplying step, wherein the material is stopped from being supplied through the discharge portion into the measuring unit at a time when the quantity of the material measured by the measuring unit reaches the final measuring target value.
