Ball mill grinding fineness of grinding production cost impact analysis is part of the concentrator high, how effective and reasonable control of the grinding fineness is dressing directly reduce costs, improve important economic factor processing plant. We must first fully understand the factors of grinding fineness. To sum up, the grinding fineness factors are: ore hardness, crushing particle size, the grid mesh sieve, to the ore size, number of balls, ball size ratio, ball mill liner wear, ball mill Pai mine mouth flush size. Understanding all of these factors in the production operation, we want to find, magnetic tailings recycling machines one by one to find the best adjustment factor. Ore mineral hardness: different minerals, its hardness is not the same, this factor is fixed with respect to the same ore, but also can not be adjusted. However, in production, under the premise of beneficiation technology requirements can be reasonably ore, the ore as possible uniform size, bulk, powdered ore ratio is reasonable stable. Grading machine spindle lifting height, is also an important factor in returning the amount of sand and grinding fineness of. The normal grading machine spindle production requirements into place. Some workers in the concentrator milling equipment maintenance, since the grading machine not clean ore, tailings recycling machine manufacturers, sink set in a long time, tailings recycling machine equipment, heavy sludge than real, Beijing tailings recovery machine, grading machine spindle at the lower levels, because they do not care, did not completely drop spindle, resulting in less than normal amount of sand back situation. Broken particle size, grate sieve adjustment is construction related, grader blades wear: worn blade with respect to return the amount of sand is reduced, resulting in grinding fineness thicker, in addition, if badly worn blades, will affect grader life, so timely inspection work in blade wear, classifier overflow weir level, affecting the size of ore precipitation zone, in production we can request the grinding fineness and appropriate for the grade level adjustments overflow weir If the requested grinding fineness thinner, can be welded angle iron at a certain height grader both edges, with inserted wooden pull method to adjust the level of the classifier overflow weir, sometimes after long-term accumulation of sludge, can naturally raise overflow weir height. What are the characteristics of tailings recycling machines tailings tailings recovery can effectively reduce the loss of control of 3% or less (by volume) effectively reduce the water content of the end of the active ingredient, a good solution to the tailings on the environment pollution, environmental requirements to meet emission standards, widely used in metallurgy, mining, water conservancy, hydropower, gravel plant, glass factory, coal preparation plant coarse coal recovery and environmental engineering, shield (mud purification) and other projects. Today to introduce the characteristics of tailings recycling machines. 1, simple structure, low energy consumption: the ordinary cycloid reducer, no complex speed control system and sophisticated sensing plate unloading device, than similar products, energy 20% -50%. Overcome the top of the discharge from the disk, the disk loose mechanical structure exists, string axis and other defects fundamentally. Tailings recovery machine running, add the oil in addition to the timing and replacement of the outer rubber scraper without regard to mechanical failure. 2. The unloading easy, magnets do not wear: the moving magnetic field technology, water will be sucked slag in force, by means of mobile magnetic field, the automatic collection of slag near the outer edge of the disk, since the disk outer edge to the same pole (N or S), and then the magnetic field at the same level repulsion principle, the blade can easily be scraped off and the magnetic surface leaving a protective layer. 3. processing capacity, high recovery rate, water consumption: thanks to complex magnetic system consisting of poly-magnetic technology makes the surrounding magnetic disk depth, high field strength, gradient large site with other similar products using comparison recovered amount Their 2-3 times, due to the recovery of a large amount of slag inclusion absorbed by a sufficient amount of water is sufficient to discharge the red mine water conservation.
