<p>PROBLEM TO BE SOLVED: To provide a supply amount control method of a raw material storage and supply device in which a problem associated with control accuracy of a supply amount (weight) of a second raw material supply device is resolved and an accurate supply amount control method is realized by following the specific gravity change of raw material, regarding raw material supply for increasing a production amount of resin pellets by an extruder.SOLUTION: The raw material storage and supply device comprises a hopper 2 which stores raw material and can measure the weight of the raw material stored, a first raw material supply device 3 which is arranged at the hopper 2, supplies the raw material from the hopper 2 to a first processing device 4 and can measure and control the weight of the raw material to be supplied, and a second raw material supply device 9 which is arranged at the hopper 2 as independent from the first raw material supply device 3, supplies the raw material from the hopper to a second processing device 11 and can control the volume of the raw material to be supplied, and, upon controlling the weight of the raw material to be supplied to the second processing device 11, the volume of the raw material to be supplied from the second raw material supply device 9 is controlled based on the specific gravity change of the raw material to be supplied.</p> |
