Embodiment 1
[0027] Embodiment one: the density (bulk specific gravity) is 0.62g / cm 3 The powdered vanadium pentoxide is continuously added to the feeding system (the system is composed of a pre-feeder with a mechanical vibration device and a forced-feeding screw hopper to ensure the continuity, adequacy and Uniformity), and then the vanadium oxide is forced into the flaking machine and the crushing and sizing system by the feeding system. 2 The granulation process is completed under certain conditions, and the obtained product has a particle size of 0.3-10mm and a density (bulk specific gravity) of 1.45g / cm 3 .
Embodiment 2
[0028] Embodiment two: the density (bulk specific gravity) is 0.69g / cm 3 The powdered vanadium tetroxide is continuously added to the feeding system (the system is composed of a pre-feeder with a mechanical vibration device and a forced-feeding screw hopper to ensure the continuity, adequacy and Uniformity), and then the vanadium oxide is forced into the flaking machine and the crushing and sizing system by the feeding system. 2 The granulation process is completed under certain conditions, and the obtained product has a particle size of 0.3-10mm and a density (bulk specific gravity) of 1.74g / cm 3 .
Embodiment 3
[0029] Embodiment three: the density (bulk specific gravity) is 0.77g / cm 3 The powdered vanadium trioxide is continuously added to the feeding system (the system is composed of a pre-feeder with a mechanical vibration device and a forced-feeding screw hopper to ensure the continuity, adequacy and Uniformity), and then the vanadium oxide is forced into the flaking machine and the crushing and sizing system by the feeding system. 2 The granulation process is completed under certain conditions, and the obtained product has a particle size of 0.3-10mm and a density (bulk specific gravity) of 1.94g / cm 3 .
