Embodiment Construction

[0022] The application effect of the present invention will be illustrated below through examples of separating quartz and hematite particles by a Φ50mm hydrocyclone.

[0023] 1. Determine the parameter conditions (including structural parameters and operating parameters) of the hydrocyclone as shown in Table 1.

[0024] Table 1 Parameter list of Φ50mm hydrocyclone

[0025]

[0026] 2. Determine the operating parameters of the target working condition: the ore feeding pressure is 0.1MPa, and the ore feeding concentration is 10%.

[0027] 3. Determine the physical parameters of the material to be separated: the separation medium is water, and the air column of the hydrocyclone is considered. The density of water is 998.2kg / m 3 , the dynamic viscosity is 1.003×10 -3 Pa s; the density of air is 1.225kg / m 3 , the dynamic viscosity is 1.7894×10 -5 Pa s; the density of quartz is 2673kg / m 3 ; The density of hematite is 4858kg / m 3 ; The particle size composition of quart...

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.

Description

technical field [0001] The invention relates to a mineral processing grading hydrocyclone, in particular to a method for determining the separation granularity of the hydrocyclone, which belongs to the technical field of mineral processing engineering. Background technique [0002] Our country is rich in mineral resource reserves, but there are very few rich ores that can be directly applied in industry, and most of them are lean ores that need to be sorted and processed before they can reach the industrial application standards. Classification is the process of dividing loose materials into products of different particle sizes, and is an essential link in the mineral separation process. Hydrocyclone is the most widely used grading equipment, and it is used in almost all mineral processing plants in the world due to its advantages of low cost, large processing capacity, and small footprint. [0003] Separation particle size is the quality index of hydrocyclone classificatio...
