In a particle measurement device (1) for a powder or granular material processing apparatus, powder or granular material is introduced into a drawing tube (3), which is formed to be projected from the inside of the granulating vessel (2), by injecting high pressure gas from the inside of the granulating vessel (2), so as to capture it with adhesive film (6). The captured powder or granular material is photographed, and, based on the obtained image information, information on the powder or granular material within the granulating vessel (2) is obtained. An air inlet (4), which is communicated with the drawing tube (3), is provided in the drawing tube (3) in the neighborhood of its end portion (3b) on the side of the outside of the granulating vessel (2). Through this air inlet (4), gas having higher pressure than the inside of the granulating vessel (2) is introduced into the drawing tube (3). By this, in the particle measurement device for the powder or granular processing apparatus, effects of remaining powder or granular material and flow out of the powder or granular material are removed, and grain size etc. are measured with high reliability. <IMAGE> |
