NOVELTY - Crushed plant raw material (24) is supplied to a vertical mill (32) with a classifying-rotation separator. Rotation grinding of raw material is carried out with the roller by rotating a grinding table. Ground material is dried and conveyed to a separator by gas from the bottom portion of the table. Particles and coarse components are classified, the coarse component is returned to grinding table, and the particle component is pelletized to obtain plant pellets.    USE - Used for the manufacture of plant pellets used as an alternate fuel of coal, and the manufacture of a plant composite material (claimed) used as wood meal, such as manure raw material.    ADVANTAGE - The manufacture produces plant pellets economically using inexpensive kenaf, and enables effective recycling of plant raw material consisting of saw dust, grass, coppiced timber, wood-waste material and wood chips.    DETAILED DESCRIPTION - Preliminarily crushed plant raw material (24) is supplied to the grinding table of a vertical mill (32) with a classifying-type rotation separator arranged on the grinding table upper portion. The rotation grinding of raw material is carried out with a roller by rotating the grinding table. The ground material ejected from the grinding table periphery is dried and conveyed to the separator by gas from the grinding table periphery downward direction. The particle component and coarse component are classified, the coarse component is returned to the grinding table, and the particle component is ejected out of the grinding unit with a gas. The particle component is then separated from the gas, supplied to a pelleting machine (62), and plant pellets of predetermined shape is manufactured continuously.    INDEPENDENT CLAIMS are also included for the following:    (1) a manufacturing apparatus for the plant pellet; and    (2) the manufacture of a plant composite material.    DESCRIPTION OF DRAWING(S) - The figure shows the block explanatory diagram of the structure of manufacturing apparatus of the plant pellet.
