what we offer

Smart Linear Feeder with smart dosing control

The highly flexible PFISTER® SLF belt weighfeeder can be used for a wide variety of materials. Fine, coarse or sticky – whatever you need to feed, at rates from a few hundred kg/h up to 1500 t/h. This continuous gravimetric dosing system has the reliability factor of the PFISTER® rotor weighfeeders, but this is a linear system where weighing takes place on the belt. Just like the rotor weighfeeders, it’s built to withstand the harsh environment of an industrial processing plant. The wear-resistant design ensures high availability while the patented integrated control – PFISTER® SDD-Control – guarantees easy operation. It can be designed for extreme hot and cold environmental temperatures.
