Effect of different additives on the ball milling process during operation of the ball mill, various process parameters have a milling process produces a large or small impact, such as ball diameter, additive nature, etc., wherein the additive's role is to regulate the milling tank The physical properties of materials and operational status, the following analysis will focus on the effects of different additives on the ball milling process. Conduct analysis for the three trials, choose different additives: add water without ethanol 6mL, plus stearate 5g, no additives, to analyze the impact of the milling process. Test results at right: Since liquid ethanol can carry and disperse the powder, and the powder can reduce the surface energy and play a role in the absorption of heat, during the milling process, the appropriate amount of ethanol was added to make a paste powder distribution on the ball and the inner wall of the tank, powder thinning rate is higher than the other two groups. Ball milling method is a high-energy ball milling, ball milling process, the consumption of alcohol quickly, experiment 4h after milling ethanol almost spent, continue milling is generated agglomeration, agglomeration even more than the last set of the degree of blocking dry grinding. According to the test results, the ball mill, the first set of tests, to ensure good wet-milling state, controlling the amount of ethanol added is the key addition of the slurry will be too thin too, powder for ball attachment resistance will be weakened; too small an amount, the slurry is too thick, make the ball movement difficult, and too thick slurry easy to agglomerate. In the second group, stearic acid is a solid surfactant, which can effectively prevent the oxidation of powder, its friction reduction and dispersion powder is very clear, and the refinement of the lowest rate of the test material . To sum up: the effect of wet grinding mill is far better than the situation without dry grinding dry grinding and processing of solid acid additives, not only high efficiency refining powder, the powder can effectively prevent caking, oxidation and so on, but it must be added to control the amount of wet milling additives. What are the common faults ball mill job, there will be severe vibration phenomenon, which may be at the time of installation, there is no fixed base, or is not broken into the material, and so on. In addition to these common faults ball, what does? A main bearing leakage reasons: ① pipe joints lax; ② spherical bush cracks. Solution: ① joint sealant reassembled Beijing mill, pipe joints enhance sealing; ② bonding method or welding method spherical bush crack repair. Second, the drive shaft and bearing bolt breaking reasons: ① shaft coupling is not installed correctly, the deviation is too large; the ② shaft overload; ③ shaft insufficient strength or poor quality; ④ bearing installation errors , or connecting bolts loose (or tight). Solution: ① re-adjust the coupling installation; ② prevent overload phenomenon; ③ replace good quality shaft; ④ bearing installation alignment, replace the bolts, tighten the bolts to moderate. Third, the liner material leakage at the connecting bolt reasons: ① liner bolts loose or broken; ② severe liner wear; ③ gasket wear. Solution: ① Tighten or replace bolts; ② repair or replace liner; ③ Replace gasket. Mill and balance shaft gear, ball manufacturers, since the axis is not in a straight line, causing great vibration reducer drive the ball when: Four great causes vibration reducer drive when a ball mill. Workaround: To re-adjusted so that the ball mill gear axis and the axis in the same plane as the axis line. Fifth, the feed end of the drain material reasons: ① intake valve is between the feed tube with the feed screw and the gap between the feeder and hopper large, poor sealing; ② felt seal pad wear or fall off. Solution: ① adjust the gap, sealed; ② replace the felt. Beijing Public into the ball mill _ _ North mine mill equipment from Shenyang North Mine Zhongcheng machinery Limited.
