Apparatus and method for granularity management

Provided are an apparatus and a method for particle size management in which the particle size of a raw material can be accurately analyzed and managed. In particular, the present invention relates to a particle size management device and a method for applying the same, the particle size management device comprising: a transport unit for transporting a raw material; a sorting unit for sorting small particles from the raw material and retaining large particles larger than the small particles; a photographing unit disposed to face the transport unit to obtain an image of the large particles; and an analysis unit that analyzes the particle size distribution of the raw material on the basis of the image obtained by the photographing unit. 本发明提供了用于粒度管理的装置和方法，其中，可以准确地分析和管理原料的粒度。特别地，本发明涉及粒度管理装置及其应用方法，粒度管理装置包括：运输单元，其用于运输原料；分选单元，其用于从原料中分选小颗粒并保留比小颗粒大的大颗粒；拍摄单元，其被设置成面向运输单元以获得大颗粒的图像；以及分析单元，其根据由拍摄单元获得的图像对原料的粒度分布进行分析。
