Abstract: A process and apparatus for pelletizing tree bark and other botanical material for use as an industrial fuel. A dryer burning fines from the final product is used to heat bark or other botanical material which is typically a waste product from lumbering or agricultural production. Once dried, the material is finely ground, preheated and forced through a pelletizing mill to create a pelletized product having a diameter of approximately 0.635 cm. The pellets are then cooled and leave the process. Several pelletizing mills are disclosed which are situated to trap the dried material against at least one die such that there will be a continuous, positive feed of material into the die. The resulting product may be substituted for coal as a heating source.
