For providing a method of applying raw materials capable to make control of manufacturing easier and to make a compound stable in quality, firstly each raw materials is respectively measured. Secondly, by packing each of the raw materials with each determinate quantity in a packed form of each bag, each pack of raw material can be given. Preparing each of the required numbers of the packs of raw material corresponding to each of required quantities of the raw materials, the prepared packs of raw material are supplied into a mixing-tempering machine 31. Thereafter, the mixing-tempering and pelleting processes will be acted, and the compound stable in quality can be provided.
