Along with the wide application of biomass pellets, wood pellet mill is more and more used nowadays. Mold, as the easy-wearing part of wood pellet mill, is required more and more today in markets. The compression ratio of mold refers to the ratio between diameter and effective length of die hole. As to the selection of compression ratio, it is based on the desired formula of biomass pellets.
If you want to make the fodders rich in cereal, compression ratio of mold will be better at about 8-12.5. To produce fodders with sensitivity to heat, compression ratio of mold should be controlled at about 5-8. While, for the production of concentrated fodders rich in natural protein, compression ratio of mold should be at about 5-11. If you want to make the fodders specially for milk cow, the compression ratio of mold should be controlled at about 7-15.
As to the detailed adjustment for the compression ratio of mold, it is more dependent on your demands toward the quality of biomass pellets. Low compression ratio of mold is effective to increase the output, lower the energy consumption and alleviate the wear. While, the biomass pellets produced by wood pellet mill will be quite poor in density and high in powder ratio.
