PURPOSE:To obtain the no-man and labor-saving titled device selectively feedable various kinds of particulate materials by a structure wherein a slider equipped with through holes selectively communicating to a hopper for feeding particulate materials is slidably arranged at the upper part thereof. CONSTITUTION:A slider 14 is adjusted, for example, so that the desired hole of the through holes 15 equipped thereon comes into coincidence with the hopper 5 and then the material is fed to a cyclone 18 under the actuation of pressurized air or vacuum in order to feed a predetermined amount of the material in the hopper 5 by successive falling. After that, a plasticator 1 is put into operation in order to perform melting and kneading. On the other hand, when the switching to a different kind of the material is requested, said slider 14 is slided after no previous material exists within the hopper 5 in order to adjust another through hole 15, which is connected to a desired material storage tank formed on the slider 14, so as to coincide with the hopper 5 in order to feed the material in the hopper 5 in a similar manner as described above. |
