Abstract: Wood meal comprises wood meal granules formed by crushing raw material wood into treated wood meal and pulverizing the treated wood meal under the frictional forces of a plurality of balls such that the bulking density of the treated wood meal is increased; and a plurality of particles fixed on the surfaces of the wood meal granules by an external pressing force. The particles are smaller than the wood meal granules such that the wood meal granules are coated with the particles. The particles are also harder than the wood meal granules such that the particles are pressed into the wood meal granules surfaces from the application of the external pressing force.

Abstract: The present invention relates to wood meal prepared by crushing raw material wood to obtain treated wood meal, pulverizing the treated wood meal under frictional forces of pulverizer balls to obtain wood meal granules with increased bulking density, preparing particles that are finer and harder than said granules, and fixing said finer particles onto the surface of the granules by external pressing force. Said finer particles may also be fixed on said treated wood meal in the process of pulverization to increase the bulking density or on said granules that have been increased of the bulking density. The finer particles may include one or more kinds selected from pigments, electroconductive substances, inorganic substances, plastic materials, and metallic materials.
