Embodiment 1

[0027] Embodiment 1: the present invention is as follows to the concrete production operation process of iron ore:

[0028] Through production practice, the size of the ore inlet is 50mm×20mm, the diameter of the cylinder is 250mm, the height is 170mm, the height of the conical cylinder is 595mm, the cone angle is 20°, the diameter of the overflow pipe is 50mm, the diameter of the discharge port is 25mm, and the thickness of the cylinder is 10mm. Open the device of the present invention, open the valve 5 for controlling the amount of slurry, the slurry passes through the slurry inlet pipe 3, and the flow section is circular and extruded into a flow section with a rectangular shape, passing through the reducing tube 9, and entering the cylinder along the cylinder wall 20. Under the action of inertia, the self-flow rotates, and at the same time, under the high-speed agitation of the impeller 22, the slurry accelerates the layering and classification of coarse and fine particles,...

Abstract

The invention relates to a fuzzy closed circuit self-turning dynamic hydraulic cyclone classifier which is characterized by comprising a reducing underflow pipe, a tapered cylinder body, a slurry inlet pipe, sealing rings I, a valve, a slurry inlet particle size analyzer, a slurry inlet pressure gauge, a slurry inlet flowmeter, a reducing pipe, a control computer, an overflow cylinder body, a motor, a bearing, a sealing ring II, a bearing cover plate, an overflow pressure gauge, an overflow flowmeter, an overflow particle size analyzer, an overflow pipe, a cylinder body, a center shaft and an impeller. The classifier can achieve an optimal classification effect by replacing the reducing underflow pipes with different diameters according to the particle size composition properties of different minerals, can improve the rotating separation strength of slurry body particles in the cylinder body, and is high in automation degree and control precision, and good in classification effect.

Description

technical field [0001] The invention relates to the technical field of mineral processing equipment, in particular to a fuzzy closed-circuit self-tuning dynamic hydrocyclone classifier. Background technique [0002] Grinding is the most energy-consuming operation in a concentrator. Improving the grinding efficiency is a key issue for reducing the cost of beneficiation and saving energy. Improving the classification efficiency of the classification equipment is one of the effective ways to solve this problem. The spiral classifier commonly used in domestic dressing plants has a very low classification efficiency, generally 20-40%, and the classification efficiency of conventional hydrocyclones is only 40%-50%, causing a large number of qualified particles that have been ground to return to the mill. The regrinding of the mining machine will cause serious overgrinding and useless work. At the same time, if the classification efficiency is improved, it will not only reduce the...
