Multifunctional mineral processing device

Abstract

The invention relates to a multifunctional mineral processing device, comprising a primary crushing system, a secondary crushing system, a primary magnetic separation system, an impurity removal system, a secondary magnetic separation system and a screening system. The mineral processing device of the invention can separately perform two-stage crushing, two-stage magnetic separation, impurity removal and screening on minerals so as to obtain desired metallic minerals with high value. The crushing systems are perfect in processing; jamming of and damage to machines hardly occur; high safety anda short beneficiation cycle are realized; waste that pollutes environment is not produced in the process of beneficiation; and the beneficiation process is environmentally-friendly and efficient. Theprimary crushing system not only has good crushing effect, but also can play the role of drying and impurity removing. The two-stage magnetic separation systems finely screen the minerals and screenout the metallic minerals with economic value; and since the screening system classifies and collects ores according to the sizes of the ores, subsequent treatment can be simplified and beneficiationefficiency can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of mineral processing equipment, and in particular relates to a multifunctional mineral processing device. Background technique [0002] The main characteristics of my country's iron ore are "poor", "fine" and "miscellaneous". The iron grade is 32%-37%, which is about 10 percentage points lower than the world average grade. Among them, 97% of the iron ore needs to be processed. Magnetite ore beneficiation has always been the main body of iron ore beneficiation. In my country's iron ore concentrate output, it is mainly magnetite concentrate. Mineral dressing is based on the physical and chemical properties of different minerals in the ore. After the ore is crushed and ground, gravity separation, flotation, magnetic separation, electric separation, etc. are used to separate the useful minerals from the gangue minerals. It is a process in which symbiotic or associated useful minerals are separated from each ot...

AI Technical Summary

Problems solved by technology

The current mineral processing equipment still has the following problems: First, the crushing process after ore mining is not thorough enough, and it is easy to jam or even damage the subsequent processing machines in the subsequent mineral processing process because the ore particles are too large or the hardness is too large. Not only will it affect the beneficiation cycle, but it will also cause great production safety hazards

Second, the current concentrators can only roughly screen minerals, and cannot accurately distinguish and strip high-value ores with metal properties and impurities without metal properties, which makes subsequent processing complicated and low processing efficiency

Third, the current mineral processing equipment cannot classify and collect valuable ores according to their size and particle size
