Over varying degree of crushing . According to the survey , the production of FM rock = 2.7 with different sand , stone powder content of the feed rod mill ranked highest export more than 30 %. For example , when Wuqiangxi engineering mechanisms rod mill sand, sand control in the finished powder content of 12%, the yield is generally only about 60% (FM maintained at between 2.4 to 2.8 ),<a href="http://www.lightcrusher.com/solutions/copper-ore-beneficiation-plant.html">copper ore beneficiation plant</a> the amount of finished sand -containing powder 17 %, the yield is only about 70% (FM = 2.7 ± 0.2). However, some projects powder content of only 12% ( rod mill at the outlet ) . The former is 2.5 times the latter or even more.
Finished sand grain shape is different . Practice shows that the content of the finished sand particles flakiness lithology varies also because , in general , brittle rock obtained tabular grain high sand content .abrasive rock that rocks on its rod mill grinding rod wear disparity , the difference sometimes up to a few times. For example, Wuqiangxi project using quartzite, quartzite <a href="http://www.lightcrusher.com/solutions/sand-making-plant.html">sand making plant</a> , grinding rod wear amounted 2.26kg/m3, while the amount of ground limestone sometimes wear only 0.058kg/m3.Thus, in the structure and operating speed under certain circumstances rod mill , its adaptability to all kinds of rock is not the same . For some rocks , the use of a rod mill grinding is appropriate, some rocks are not, so we must carefully consider in the selection of the time.
Both the non-ferrous metal ores or precious metals ore concentrator , or iron ore or gold concentrator, which is a great amount of tailings ; transport and stockpiling of grain size depends on the method of tailings and tailings moisture content : coarse tailings plant output can be used to re-elect tub , belt conveyors , lifts and railways transportation methods ; flotation and magnetic separation plant plants discharge tailings slurry -like , generally use sand pump transport through pipeline to the tailings . For the complete set of gold processing equipment including gold ore crusher, mill gold , gold flotation machine , magnetic separator gold , gold and other mineral processing equipment shaker . Choice Gold devices can be divided into two kinds of sand and rock gold processing equipment gold ore processing equipment, is currently the most widely used of these two plant beneficiation . For gold ore tailings processing equipment generates , made the following described !
Lessons learned through the years, the general method to improve mill output: placing fine crusher before the ball mill; improving grinding system; im...
