難い。Conventional technology Although there have been many automatic particle size measurement devices in the powder area using suspension permeation methods, there has never been an automatic particle size measurement in the fine particle area; Sampling is carried out from the plant or incoming raw materials, and the samples are taken back to the laboratory and separated by a vibrator 11, and then measured using an electronic balance. Since feedback is also slow, granularity control is not sufficient. As a result, the quality and durability of the product do not improve, and the quality and molding dimensions of the product vary.Furthermore, the results of particle size measurement are not systematically recorded, making it difficult to obtain a VF crushing history.
