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.
Claims39
Wood meal comprising:
- a) 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 resulting wood meal granules have substantially rounded shape without rugged edges and without elongated protruding portions, thereby increasing the bulking density of the treated wood meal;
- b) plurality of particles fixed on the surfaces of said wood meal granules by an external pressing force;
- c) said particles being smaller than said wood meal granules such that said wood meal granules are coated with said particles;
- and
- d) said particles being harder than said wood meal granules such that said particles are pressed into said wood meal granules surfaces from the application of the external pressing force.
Wood meal made from raw material wood by the process comprising the steps of:
- a) crushing the raw material wood into treated wood meal;
- b) pulverizing the treated wood meal into wood meal granules by the frictional forces of a plurality of balls such that the resulting wood meal granules have substantially rounded shape without rugged edges and without elongated protruding portions, thereby increasing the bulking density of the treated wood meal;
- and
- c) fixing a plurality of particles to the surfaces of the wood meal granules by applying an external pressing force, said particles being harder and smaller than the wood meal granules such that said particles are forced into the surfaces and coat said wood meal granules.
