CENTRAC is the ideal machine for emptying a silo filled with bulk material with problematic flow properties.
CENTRAC basically consits of
– the CENTRAC floor, which is also the silo floor,
– the CENTRAC cone,
– the CENTRAC discharge arm and
– the CENTRAC drive.
In the center the floor of the CENTRAC has an outlet opening. The CENTRAC cone is located above the outlet opening at a distance to the floor and prevents the bulk material from uncontrolled flow out. The CENTRAC discharge arm is rotated by the CENTRAC drive over the CENTRAC floor. Due to its special shape, it conveys the bulk material to the central outlet opening, through which it flows downwards. The speed control of the CENTRAC drive by means of a frequency converter enables the discharge of an exact, constant and controllable quantity of bulk material. The main advantage of CENTRAC is that the bulk material is kept in motion over the entire diameter of the silo.
This ensures mass flow, avoids bridging and enables emptying of the silo according to the “first in – first out” principle.
