Title:
クリンカの製造方法及びクリンカ製造装置
Document Type and Number:
Japanese Patent JP7226227
Kind Code:
B2
Abstract:
To efficiently produce a clinker that satisfies predetermined qualities.SOLUTION: A method for producing a clinker includes the steps of: obtaining an image of the clinker discharged from a kiln; measuring the size of the clinker based on the obtained image to detect particles having a threshold level or more of a size; obtaining an extraction parameter from the image with regard to the detected particles; and extracting the particles from the clinker when a value of the obtained extraction parameter does not fall within a setting range, wherein the extraction parameter is at least one of circularity calculated through the following formula (1): C=4πS/g2, a difference between an average temperature of the clinker and temperature of the particles, and an L* value in the L*a*b* color expression system of CIE (Commission internationale de l'eclairage). In the formula (1), C: circularity, S: an area of the particles obtained based on the image, and g: a boundary length of the particles obtained based on the image.SELECTED DRAWING: Figure 2
