Title:

SEPARATING DENSITY FORECASTING METHOD AND FORECASTING MODEL CONSTRUCTION METHOD AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2023/193656

Kind Code:

A1

Abstract:

A separating density forecasting method and a forecasting model construction method and device. The forecasting model construction method comprises: performing fluidization operation on dense-medium particles in a fluidized bed to achieve bubbling fluidization; suspending, by means of a dynamometer, minerals to be separated in a dry dense-medium fluidized bed, the minerals to be separated being dense ores; collecting a resultant force borne by the minerals to be separated and the bed layer density; according to the resultant force borne by the minerals to be separated and the bed layer density, the granularity and the real density of the minerals to be separated, and the bulk density of the dense-medium particles, determining a function relationship between the volume of a fluidization dead zone above the minerals to be separated in the fluidized bed and the granularity of the minerals to be separated; and constructing a dry dense-medium fluidized bed separating density forecasting model on the basis of the function relationship.
