Embodiment 1

[0018] The Henan bauxite with an aluminum-silicon ratio of 3.5-4.0 and a large amount of slime is crushed to less than 25mm. After crushing, the ore is quantitatively transported into the wet roller mill 1 by a belt conveyor. The wet roller mill uses a vertical Mortar rotary mill, add water into the vertical mortar rotary mill, and the ore is ground into coarse pulp in the vertical mortar rotary mill. The particle size of the coarse pulp is +3mm30%. Classification equipment 2 classification, classification equipment 2 is a spiral classifier, the coarse ore particles classified by the spiral classifier enter the wet ball mill 3, add an appropriate amount of water to the wet ball mill 3 for further grinding, and the ground pulp returns to the classification equipment 2. The overflow of grading equipment 2 is discharged along the B direction as qualified pulp; the qualified pulp particle size is +0.074mm<15%, -0.038mm<55%, which is an ideal bauxite beneficiation pulp without muddy...

Embodiment 2

[0020] The Henan bauxite with an aluminum-silicon ratio of 2.0-2.5 and a large amount of slime is crushed to less than 25mm. After crushing, the ore is quantitatively transported into the wet roller mill 1 by a belt conveyor. The wet roller mill uses a vertical Mortar rotary mill, add water into the vertical mortar rotary mill, and the ore is ground into coarse pulp in the vertical mortar rotary mill. The particle size of the coarse pulp is +3mm40%. Classification equipment 2 classification, classification equipment 2 is a spiral classifier, the coarse ore particles classified by the spiral classifier enter the wet ball mill 3, add an appropriate amount of water to the wet ball mill 3 for further grinding, and the ground pulp returns to the classification equipment 2. The overflow of grading equipment 2 is discharged along the B direction as qualified pulp; the qualified pulp particle size is +0.074mm<15%, -0.038mm<60%, which is an ideal bauxite beneficiation pulp without muddy...

Embodiment 3

[0022]The Shanxi Yangquan bauxite with an aluminum-silicon ratio of 3.5-4.0 and no slime is crushed to less than 25mm. After crushing, the ore is quantitatively transported into the wet roller mill 1 by a belt conveyor. The wet roller press uses a vertical Rotary mortar mill, add water into the vertical rotary mortar mill, and the ore is ground into coarse pulp in the vertical rotary mortar mill. The particle size of coarse pulp is +3mm20%. Classification by grading equipment 2, grading equipment 2 is a spiral classifier, and the coarse ore particles classified by the spiral classifier enter the wet ball mill 3, and an appropriate amount of water is added to the wet ball mill 3 for further grinding, and the ground pulp returns to classification Equipment 2, the overflow of classification equipment 2 is discharged along the B direction as qualified pulp; the qualified pulp particle size is +0.074mm<15%, -0.038mm<45%, which is an ideal bauxite beneficiation pulp without muddy phe...

Abstract

The invention discloses a low-consumption ore grinding method for ore for beneficiation. The low-consumption ore grinding method for the ore for the beneficiation is realized by combining a wet-process rolling-type mill 1, classifying equipment 2 and a wet-process ball mill 3. The ore is conveyed from the direction A to enter the wet-process rolling-type mill 1; water is respectively conveyed from the direction A to enter the wet-process rolling-type mill 1 and enter the wet-process ball mill 3 from the direction C; ore pulp levigated by rolling in the wet-process rolling-type mill 1 enters the classifying equipment 2; coarse ore grains separated by the classifying equipment 2 enter the wet-process ball mill 3; the ore pulp reenters the classifying equipment 2 after being further levigated in the wet-process ball mill 3; and the overflow of the classifying equipment 2 is discharged along the direction B and is qualified ore pulp. The wet-process rolling-type mill 1 is a mortar rotary mill. The classifying equipment 2 is a spiral classifier. The low-consumption ore grinding method for the ore for the beneficiation has the positive effects that ore grain argillization is overcome; the dissociation is complete; and the investment, the power consumption and the ball consumption are saved.

Description

technical field [0001] The low-consumption grinding method of ore for mineral processing is suitable for the mineral processing industry of metal ore and non-metallic minerals, and is used for the dissociation process of useful minerals and gangues, and is suitable for minerals with useful minerals as crystallization cores and surrounded by gangues The dissociation of minerals in the state of occurrence is especially suitable for the dissociation process of minerals such as bauxite, magnetite, apatite, fluorite and other minerals in direct and reverse flotation. Background technique [0002] With the increasing depletion of bauxite resources in my country, my country's huge alumina industrial production capacity will have to rely on bauxite beneficiation technology to ensure the supply of qualified bauxite for smelting. At present, the bauxite beneficiation technology has been put into production and application in Zhongzhou Aluminum Plant, Hope Aluminum, Cayman Aluminum and...
