Description

Ore metal separation breaker

Technical Field

The utility model relates to a technical field of ore processing especially relates to an ore metal separation breaker.

Background

The precondition for mineral separation is to separate the valuable minerals from the ore by monomers, and since the valuable minerals are present in the form of monomers with a small particle size, the ore is often ground to a very fine size in order to separate the valuable minerals from the ore by monomers. The crushing and grinding of the ore is a preparatory operation prior to beneficiation.

The crushing of ore is a process of breaking up the large ore by means of the external force of the crusher to overcome the intermolecular force inside the large ore and gradually reduce the granularity of the large ore. In the process of ore dressing, ore crushing is generally divided into two main stages, namely a coarse ore crushing stage and a fine ore grinding stage. In a mill, the crushing of ore is an essential material preparation period prior to the sorting operation. First, the vast majority of ores handled by mineral processing plants are closely tied together in useful and gangue deposits, and are often embedded in fine or even micro-fine particles. Only if the materials are broken up and fully dissociated, the materials can be enriched by the existing physical beneficiation method. Secondly, all physical ore dressing methods are restricted by particle size, and useful mineral deposits with too coarse particle size and gangue are not dissociated completely or superfine particles with too fine particle size, namely, superfine particles which are crushed cannot be sorted usefully. In each mineral separation link, the crusher is used for crushing ores and is the process with the highest cost, and the crusher is an important part of the investment and production cost of mineral separation equipment plants. According to calculation, the investment of the ore crushing process accounts for about 40% of the investment of the ore dressing plant. In conclusion, the basic task of ore crushing operation is to supply suitable selected materials for sorting operation, the quality of the operation of a crushing process directly influences the skill and economic index of ore dressing, and people think that ore crushing is the basis for determining the success or failure of the ore dressing process. Therefore, each ore dressing operator should pay attention to the selection of the skilled equipment for ore crushing work and the production management.

The ore processing is turned various and is carried out coarse crushing and fine crushing by adopting a crushing device, then screening is carried out by a screening device, and metal impurities in ore powder or particles are removed by a metal separator after screening. In the present ore processing technology, a workshop with a large area can be occupied to build and install the crushing device, the screening device and the metal separation box in sequence, the input cost is large, the processing of a production line can cause long processing timeliness, the working efficiency is influenced, and the practicability is poor.
