In ore dressing production, stone crusher occupies a very important position, which has a great influence on working efficiency, production cost, economic benefits of ore beneficiation plant. The concrete analysis is as follows. Ore crushing refers to large pieces of ores overcome internal force between the molecules and then be crushed relying on effect of external force, which is also a process of making granularity of ore block narrow gradually. In ore dressing process, ore smashing is generally divided into ore crushing(coarse phrase) and ore grinding(fine phrase).

In ore dressing plant, stone crusher is necessary material preparation phrase before sorting operation. Firstly, the ores to be processed by ore dressing plant are mostly tied together with valuable minerals and gangue mineral. Only by crushing and dissociating them can we use existing physical separation methods to enrich them. Secondly, all of physical separation methods are restricted by granularity, too coarse or too fine granularity cannot be separated effectively. In every link of iron ore concentration plant, ore crushing is both the most expensive process and important part of constituting investment and production cost of ore dressing plant. According to statistics, investment of ore crushing process accounts for about 60% of investment of the ore dressing plant, production cost accounts for 40% to 60% of total cost, power consumption accounts for 50% to 65% and steel consumption accounts for more than 50%. In conclusion, basis task of ore crushing is to provide suitable materials for sorting operation. Quality of ore crushing work directly affects ore dressing technology and economic indicators. Hence, some people think that ore crushing is the key to determine success or failure of ore dressing process. Therefore, the ore beneficiation should pay enough attention to selection of processing equipment and production management of ore crushing work.

Maintenance methods of Fine Ball Mill For Sale. In general, quality is the precondition of highly efficient operation and production of equipment. scientific and reasonable maintenance is fundamental guarantee of long-term operation of equipment. So, purchase and daily maintenance of coarse crushing equipment are fundamental starting points of long-tem running of equipment. Firstly, selection of coarse crushers should accord with ore types and form of mines. It's well known that the same work can select different machines to complete, but the effect is not necessarily the same. Hence, when choosing coarse crushing equipment, we should be cautious and combine with actual situation so as to ensure that the selected equipment satisfy characteristics of minerals to the greatest extent. Even the same minerals, we should also carry out the specificity monitoring so as to select optimal equipment. Secondly, we should also use the equipment with new technology and materials as far as possible, which can't rely on old high manganese steel materials. We can select equipment with high degree of automation. Thirdly, we should regularly check important parts of equipment so that we can find and solve problems in a timely manner. When it's necessary, we can stop production to carry out inspection so as to avoid unnecessary lose. Lastly, wear resistance of materials of equipment should be high, thus we can discover frequent troubles and other wastage beyond normal range when the equipment is in normal maintenance stage.
