【発明の名称】転動式造粒機への原料投入量自動制御装置
Document Type and Number:
Japanese Patent JP2919166
Kind Code:
B2
Abstract:
An automatic loading amount control apparatus for a granular compound fertilizer material includes a grain size distribution measurement module, a control module, a control table, and a material loading amount control module. The grain size distribution measurement module and the control module periodically measure the weight-converted grain size distribution of a formed granular compound fertilizer and calculate a center grain size and a yield on the basis of the measured grain size distribution. The control table holds the maximum yield of the granular compound fertilizer and a center grain size providing the maximum yield. The control module updates the maximum yield and the center grain size held in the table on the basis of the center grain size and the yield calculated by the grain size distribution measurement module. The material loading amount control module changes the water content of a material to be loaded such that the center grain size of the weight-converted grain size distribution of the formed granular compound fertilizer is equal to the center grain size held in the table.
