Pipe conveyor system:

Rohrfoerderanlage Kellner Siebtechnik

As a standard solution for the feeding of screening machines or other processing machines, we offer our tube conveyor RF. As with all machines and systems of KELLNER Siebtechnik GmbH, we also rely on our modular system to be able to offer individual solutions. Our RF system was designed so that the screenings can be unloaded directly as bagged goods or pre-screened via a sieve insert before being transported on to the machine. You can buy exactly the technology that you actually need in daily practice. In the same way, our machines in the RF series are characterised by constructive benefits and simple upgrade solutions
