Hammermill Surge Bin
The primary function of a hammermill surge bin in a biofuel process is to provide a controlled constant feed from a hammermill to a secondary source without taking on the wear & tear of operating a belt feeder associated with the larger sized biomass material, and yet maintain the required mobility. The surge bin is usually mounted on legs to elevate the bin to a height which permits a truck to be driven underneath the surge bin. A gate in the bottom of the surge bin is then opened and the material falls out of the bin into the truck below. Surge bins are often mounted on a trailer for easy mobility from one site to the next.
