Problems solved by technology

[0003] For the grinding and separation of iron ore after mining, the metal components inside the ore are distinguished from the non-metal components. In the actual processing process, the iron ore needs to be crushed and crushed to increase the contact area of ​​the magnetic attraction. Metal components and non-metal components are then separated by magnetic separation. The existing magnetic separation process only has a single layer of magnetic suction. After the iron ore is removed, the adsorption force of the magnetic device will decrease, and it is easy to leak the iron ore, resulting in waste of raw material ore;

Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific drawings. It should be noted that, in the case of no conflict, the embodiments and Features in the embodiments can be combined with each other.

[0027] Such as Figure 1 to Figure 5 As shown, a metal ore mining, grinding and separating method uses a metal ore grinding and separating device, the separating device includes an actuator 1 and a separating mechanism 2, and the metal and non-metallic components inside the ore are separated by using the above-mentioned separating device. The specific processing method of separation is as follows:

[0028] S1. Extrusion and crushing: the ore is crushed into small granules through the opposite rolling of the active rolling roller 13 and the auxiliary rolling roller 14;

[0029] S2. Separation and drop: through the se...

Abstract

The invention provides a metallic ore mining, grinding and separating method. The metallic ore mining, grinding and separating method involves an executing mechanism and a separating mechanism. The executing mechanism is mounted on the separating mechanism, and the executing mechanism is located over the separating mechanism. The problems that aiming at grinding and separating of mined iron ores,metal ingredients and nonmetal ingredients in the ores are distinguished, the iron ores need to be ground and smashed in the actual treatment process, the contact area of magnetic attraction is increased, the metal ingredients and the nonmetal ingredients are distinguished through magnetic separation, only single-layer magnetic attraction is achieved in the existing magnetic separation steps, theiron ores containing the metal ingredients are likely to be miss-screened in the actual ore screening process, and after multiple iron ores are adsorbed, the adsorption capacity of a magnetic attraction device is reduced to some extent, the iron ores are likely to be miss-attracted, and waste of the raw ores is caused are solved.

Description

technical field [0001] The invention relates to the technical field of metal ore separation, in particular to a method for mining, grinding and separating metal ores. Background technique [0002] Iron ore is a mineral aggregate containing iron element or iron compound that can be used economically. It can be used for many purposes such as refining simple pig iron and steelmaking; after crushing, grinding, magnetic separation, flotation, gravity separation and other procedures Gradually select iron, which is an important raw material for steel production enterprises; [0003] For the grinding and separation of iron ore after mining, the metal components inside the ore are distinguished from the non-metal components. In the actual processing process, the iron ore needs to be crushed and crushed to increase the contact area of ​​the magnetic attraction. Metal components and non-metal components are then separated by magnetic separation. The existing magnetic separation proces...
