Powder feeders
Volumetric and gravimetric powder feeders

Powder feeders

Automatically feeding a powder or granule product is advantageous in terms of feeding precision and productivity optimisation, thanks to the use of an electronic weighing systems. 

At Itisystem, we have developed a series of volumetric, single and twin screw high precision powder feeding machines, both continuous and discontinuous with low, medium and high flow for feeding powders and granules in various natures and flows, wet or dry.

    The adjustable design allows for quick and easy cleaning, whilst a wide array of screws with various profiles guarantee perfect adaptability for any application. 


    The bridge breaker placed inside the tank maintains the product's mobility and ensures smooth feeding of the screw feeder; the space between the latter and the arm of the bridge breaker has been reduced to a minimum to avoid any vacuum forming.


    In the case of twin screw gravimetric powder feeders, the screw pumps, having been fitted together, are self-cleaning so as to avoid incrustations and in order to allow the tank to be emptied, which considerably reduces the exchange time of the product and minimises the residual losses.


    The storage hoppers attached to the feeder are made with inclined walls in order to facilitate the product flow, so that it slides smoothly toward the feeder, therefore improving performance.  Also, to improve the performance we have agitators, pneumatic vibrators and fluidises available.


    By combining a feeder of both types with a load cell scale and with a microprocessor-based regulator, it is possible to obtain a continuous or a batch-fed gravimetric feeder.
