Water-saving combined cyclone classification and concentration device

Abstract

The invention relates to a device used for classifying and concentrating a fine-granule material, and especially relates to a water-saving combined cyclone classification and concentration device. The water-saving combined cyclone classification and concentration device is characterized in that the device comprises a body, a flow guide and stabilization cylinder, a primary hydraulic cyclone, a secondary hydraulic cyclone, a frame, a central overflow tube, a water and water masher and a circulating pump; the central overflow tube is arranged in the cavity of the body, the flow guide and stabilization cylinder is arranged in the cavity of the circular column of the body, the circular column of the body is provided with a tangential material inlet, and the lower end of the body is provided with a material outlet; and the lower end of the central overflow tube is communicated with the material and water masher, the circulating pump and the material inlet of the primary hydraulic cyclone through a pipeline, the overflow tube port of the primary hydraulic cyclone is communicated with the material inlet of the secondary hydraulic cyclone, and the overflow port of the secondary hydraulic cyclone is communicated with the tangential material inlet through a pipeline. The device has the comprehensive characteristics of combined classification, water saving, energy saving, high solid content of classified products, and strong adaptability to a material.

Description

technical field [0001] The invention relates to a device for classifying and concentrating fine material. Background technique [0002] The amount of tailings produced during the mineral processing of metal ores accounts for more than 70% to 90% of the total. At present, the most promising utilization methods for bulk utilization of tailings are: tailings filling, dry drainage and dry stacking and preparation New Building Materials. An important link in the process of mine tailings utilization is to obtain tailings with a certain particle size and higher concentration. [0003] At present, in the mineral processing process, the classification equipment used to control the particle size and the concentration of the sorting are mainly: various spiral classifiers, hydrocyclones and fine particle screening equipment. Specifically, how to select the classification equipment needs to consider the classification efficiency of the classification equipment used for the pulp. Due t...

Problems solved by technology

However, for the comprehensive utilization of tailings, it needs 70% to 85% or even higher, which cannot meet the needs of tailings utilization.

At present, the classification and concentration used in production are separate equipment. The classification concentration of the fine-grained grade is low, the energy consumption of classification and concentration is high, the energy utilization rate is low, and the water consumption is large, which is not conducive to energy saving and water saving.
