100 Series Feeder

Call for Information

Our 100 series feeders are our most popular feeder which offers the most versatility of all our feeders. The design offers a 100mm (4”) in diameter feeding disc. The base feeder design is sized to feed low rate feeding applications .01 to 200lb/hr (0.005 to 90kg/hr). All rates can vary based upon the density, flow-ability, and size of material.


The 100 series small size allows easy mounting to almost any processes. Like our 50 series it holds unlimited possibilities! No auger or vibratory feeders can match the 100’s capabilities, in terms of size, feeding capability and repeatability.
All of Mahr’s Disc series feeders are designed to handle bulk materials ranging from powder to pellets. This rate can vary based upon the density, flowability, and size of material.
