Welcome to inquire! Contact: Cattle Ocean Road. After long-running ball spherical bush need regular tile surface scraping treatment: Some people think that after the spherical bush run a certain time, and the hollow shaft journal package contact angle becomes large, tile surface due to normal wear and tear, the contact surface will become very Light, original oil spots will be gone, so in the course of tile will hold tile or bush-burning lurking danger, hence the need for regular scraping tile surface treatment, in fact, in the long run process the contact surface of the tile surface mill equipment and hollow shaft journal's been running very well, scraping any quality are difficult to achieve, so in normal use of spherical bushes were scraping tile is worthless, as After long-running spherical bush, with the hollow shaft journal contact angle is not the package becomes large, because in the course of the operation, along with contact uncertain dynamic load, hollow shaft journal and spherical bush and not strictly confined within the package corner early running, carrying these uncertainties Center Drive mill equipment, enough to expand the contact area at any time worn corners, which automatically limits the expansion of the real corners. As the initial oil-point loss on the spherical bush Center Drive mill price, more conducive to the formation of the oil film, in fact, there were many years and the amount of operation not made any spherical bush scraping process. Fine grinding mill particle size range of material handling equipment narrower than the small grinding, fine grinding mill feed size is generally not more than 0.3mm, even a small part to 0.1mm, grind particle size up to 0.074mm, the grinding ratio of only 4.1 Even when grinding mill equipment to 0.038mm center drive ball, grinding ratio is only 7.9, while coarse granularity is usually up to the mine 10 ~ 20mm, 25mm part processing plant even up above ground to particle size 0.3mm grinding time ore than grinding ratio up to 33.3 ~ 66.7 fine grinding mill is much greater than when, due to a narrow particle size range finely processed for grinding media size choices put a higher demand, while the media type and ratio requires less. With the impact of the original ore hardness ore grinding size tapering gradually weakened, and the impact of product fineness is gradually increased, due to the uneven nature of similar ore ore particle size and mechanical properties of the more coarse micro-cracks more, mechanical strength worse, more easy to wear, and the mechanical strength of the particle size the more details the better, the more difficult ground, with 3 ~ 0mm quartz and calcite (Mohs hardness of 7 and 3, respectively) were ground under the same conditions, so that they are ground to 0.04 mm accounted for 90%, the hard quartz needs 80min, and soft as long as calcite 50min, demonstrate the impact of the hardness of fine grinding efficiency persists, addition, and with two levels of thickness of the same material in the same mill under the same conditions of time, The results newborn less than 19um particle yield is produced after the rough ground level and more detailed levels produced little more fine granularity prove more difficult to grind. You can see by the relevant conclusions, when for hard and soft calcite quartz finely ground, the more products worn thin, thin gap freshman level yield smaller, more fine granularity proof grinding, ore hardness waning influence while the impact of product fineness gradually increased mill 2130 Center Drive, the reason for this phenomenon, partly because the particle size after thinning, macroscopic and microscopic cracks particles decreases, the particle is relatively homogeneous, and defect reduction, and therefore Even the strength soft minerals also enhanced.
