How to choose a dry materials feeder
Many processors of dry bulk materials -- and occasionally some equipment manufacturers as well -- assume that the proper selection of feeding equipment is more an art than a science. Quite the opposite is true. The requirements of any feeding application can be analyzed and quantified according to several relevant criteria. The purpose of this article is to set out the criteria and to offer guidelines for their use.
The following are the most important criteria to consider in making a feeder selection:  accuracy of feed required,  process control specified;  type of material to be W  feed rates required;  construction materials required,  budget limitations; and  upstream and downstream equipment used.
