Push floor container in diverse sizes for raw material storage and fully automatic feed of the STR dryer series. The push floor can be filled from the top using a wheel-type loader or another conveying unit. At the bottom of the container, two independent pushing units are responsible for the dosage of the raw material into a frontal hutch with a screw conveyor. Several sensors monitor the procedure and ensure that the correct material quantity is conveyed without bridge formation. The driving rods are operated via a hydraulic aggregate and a hydraulic cylinder. The dryer control monitors and controls the material output. In the outdoor area, the push floor container can be opened for filling purposes via a roof connected to the hydraulic system and closed during operation. Additional humidity in the form of rain or snow can therefore not enter.
