Ore milling equipment grinding after the grading process
After the completion of the mill grinding, the next step is to do what work? According to different production requirements, the need to grind ore grading, different materials, different uses of its classification process is not the same.
After grinding ore milling equipment why grading?
In industrial production, the size of the ore handled in the crushing and grinding sorting process is, in most cases, different in size and consists of finely divided particles, granules or fine powder particles That is loose ore (or raw materials). However, in the further processing of the material, the mixture must be separated into individual grades (grain size), in which case the grain size can not exceed a certain range. [First published in mining machinery + 100 - Branch + Network] In some cases, but also from the processing of materials need to separate impurities or debris.
Construction materials in the use of ore milling equipment after grinding why grading?
In terms of building materials, in order to improve the grinding efficiency, save the energy consumption and meet the requirements of granularity characteristics of the granular material, the granular material (or crushed product) , According to their particle size or weight size grading or sorting, which is selectively collected for grading or sorting equipment called grading machinery. If the medium to disperse the particles is air, the equipment used to classify the grade is called an air classifier. In order to protect the environment, the tiny particles and the air medium separation, that is used for gas-solid separation device called separator or precipitator (also called dust collector). In the concentrator, in order to embed in the ore Forged fine particles (less than 0.1 mm) of the valuable minerals were isolated, after crushing 2 mm of the big particles using mechanical screening, because the use of sieve sieve less than Ol mm below the fine mineral particles is very uneconomical ; Therefore, the fine particles according to the particle size is divided into fine level and the level of emblem, usually wet classification set each, so more economical and reasonable.
