Abstract
The invention relates to a method for determining separation size of a hydrocyclone. The method includes steps of 1, determining structural parameters of a target hydrocyclone, operation parameters of a target working condition and physical parameters of materials to be separated; 2, establishing a flow field domain calculating model according to the above parameters and dissociating the model, and determining boundary conditions and initial conditions for calculation at the same time; 3, performing analog calculation to solve by means of computation fluid mechanics business software and discrete element business software; 4, generating a size distribution curve of the materials to be separated in overflow and sand settling products according to the analog calculation results, and accordingly determining the separation size d50 of the hydrocyclone under the target working conditions. The problem that existing separation size calculation formulas or curves are poor in using accuracy and range is thoroughly solved. The method has the advantages of low cost, high result accuracy, wide application range and the like and is more convenient and quick and labor and material saving as compared with actual separation test.
