  • Arrangement for the pneumatic removal of bulk particulate material from the floor of a storage place
    Patent number: 4123114
    Abstract: An arrangement for the pneumatic removal of bulk particulate material from the floor of a storage place is described. Pressure air conveys the stored material in a floating condition toward one end of the storage place, where it is collected and forwarded by a further material-conveying means. The arrangement not only discharges the particulate material from the storage place, but simultaneously carries out the aeration of the stored material, by hot or cold air as desired.
