What type of feeder is needed? There are two basic types of feeders: volumetric feeders and gravimetric feeders. Volumetric feeders modulate and control the rate of discharge, gravimetric feeders modulate the mass flow rate. Failure to install the right equipment can lead to problems concerning the speed of operations. Find bulk feeder manufacturers in our Equipment Guide.
