The hoppers have been properly design with slopes,allowing a constant discharge without bridge forming. The first bin meant for the small size aggregate or dust is fitted with vibratory motor to ensure the free flow. Each hopper is equipped with an adjustable opening door that determines the discharge quantity for the materials capacity in outlet, as a function of specific weight of materials.

The material is drawn out from the hoppers by means of extracting conveyor driven by a preset-able adjustable variable drive motor, coupled with worm gear boxes, that enables to increase or decrease the material output as per the job mix formul requirements. It is also possible to increase or decrease the total capacity without varying the preset settings by means of master control.
