m below the mineral particles
Crusher equipment selection and operation of a large extent, good and bad economic decisions
Calculation of crushing and grinding equipment selection and operational management is good or bad, largely determines the economic benefits of mineral processing plant. Concentrator level of technical indicators and economic indicators of good or bad, is that its roots are often broken and grinding, so workers are needed each dressing seriously broken grinding processes and equipment used in the crusher, minimize crushing and grinding of the capital.
Apart from a few rich in useful minerals of high-grade ore, the ore extracted from the mine. Most contain a large number of poor ore gangue. Of the metallurgical industry, these useful component of lean ore content of the low, mineral composition is complex, if directly used to extract metals smelting, choose energy consumption, production of high interest. In order to more economic development and the poor from low grade ore, and expand sources of mineral raw materials, ores in the smelting must go through before the separation and enrichment, to abandon most of the gangue, the content of useful minerals to meet the requirements of smelting.
There are two basic processes: first, dissociation, dressing (available in: mineral processing equipment manufacturers) in the process. Is to large ore crushing and grinding, so that a variety of useful minerals from the ore dissociate; Second, sorting, is to have dissociated from the physical and chemical properties of mineral particles according to their different points of different products selected . Since the vast majority of useful minerals in nature are together in close quarters with the gangue, and often has embedded micro-fine cloth, if you do not first make a variety of minerals separated from each other, or ingredients, even if it has another big difference between the nature, but also can not be separation. So let useful minerals and gangue from the full solution, the use of any sorting method of pre-requisite for the purpose of crushing and grinding is closely linked to the raw ore and gangue minerals useful for full dissociation.
Useful minerals and gangue not fully dissociated, crushed (recommended equipment: knife mill) process is to make the mining process of the block size decreases. Mineral particles in a variety of useful particle size decreases the dissociation process is generated by the product of particle size if the crusher is not detailed enough. Separation results are not satisfactory; and grinding product size is too small a particle crushing occurred too much, despite all the useful minerals are completely dissociated, but the separation is not necessarily a good indicator. This is because the method can handle any sorting of materials have a certain minimum size, below the lower limit of particles (that had crushed particles) effective separation is difficult. For example, the flotation of 5 ~ 10m below the mineral particles, the re-election method of mineral particles less than 19m, the recovery is still not well. Therefore, the concentrator in the crushing and grinding the basic task is to prepare well for the sorting operation, and over the full dissociation of the selected materials crushed to a lesser extent, and its size to such a material chosen for sorting methods. If the grinding operation the inappropriate choice of technology and equipment, production and operations management is not good, the end product, or choose crushed dissociation is not sufficient, or smash a serious, will cause the entire concentrator technical and economic indicators declined.
Crushing and grinding operations of equipment investment, production costs, power consumption and steel consumption is often the largest proportion, so the calculation of crushing and grinding equipment selection and operational management is good or bad, largely determines the economic concentrator benefits.
