The good functioning of the cone crusher is the premise and guarantee safety in production. When the cone crusher problems, must be promptly careful inspection, analysis, identify the causes, fixes and improvements as soon as possible, full production capacity cone crusher, create higher economic returns. Here cone crusher problems and improved methods to summarize.

cone crusher

1, to the mine funnel transformation. 2200 cone crusher to funnel a portion of the mine by mine dispensing tray to the crushing chamber, part of the mine directly into the crushing chamber. Since the feed is uneven, often resulting in overload the machine running, the expected product size uniform, moving cone, fast fixed cone liner wear, frequent replacement, seriously affected the production capacity of equipment. For the above, the mine will see the mouth of the funnel has been transformed. Replace the funnel shield. After transformation funnel all mine discharge in the distribution plate evenly into the crushing chamber to solve the uneven particle size, the machine overload and other issues.

2 and dust. PYB-2200 crusher dust seal means for the protection of the lubricating oil does not enter the dust from the dust in the main parts, in order to avoid the normal wear and tear. The original design is the use of recycled water from dust, water pressure is difficult to control. Water pressure is too high, easy to make recycled water into the bowl Warri, causing oil and water mix, water pressure is too low and reach Dust purpose, additional dust clogged sink can easily be precipitated dust, clean up is not easy. When the 1999 overhaul, endless sink. Because sponge stretchable, always in contact with the bottom and moving cone under spherical surface, blocking the dust, that dust can be prevented to ensure recycled water oil-water mixture, after six months of use is very good.

3, oil spills. Cone crusher is easy to leak during operation, if that is not timely, can easily cause poor lubrication device caused the accident. In the production process, often oil pressure, oil temperature normal, and the dust floating in the water cycle oils, demolition crane inspection found that the bevel gear lubrication bad, bowl-shaped tiles around the overflow spills sign. The main reasons for the bowl-watt back to the hole is too small, the lubricating oil section missing, small return quantity, the size of the bevel gear does not guarantee a good lubrication. Therefore, increasing the use of appropriate methods bowl tile back to the hole, to ensure oil return, solve cone crusher bowl tile bevel gear lubricating oil spills and poor problem fundamentally.

4, lubrication oil station pump maintenance. 2200 crusher CB-40 type gear pumps, lubrication equipment due to the continuous operation, easy to wear and tear caused by pump seal, causing the pump into the air instead of oil, must be repaired for about a month, replace the seals. In addition to poor lubrication also makes the pump gear wear faster, which are seriously affected the normal production of the crusher. Of two cone crushers, four pumps installed in the form of improved 1995 overhaul. The original horizontal installation, vertical installation form instead. The principle is that the pumps installed in the lubrication oil station oil below the surface, both to ensure that the pump is always working in good lubrication condition, they can take advantage of lubricating oil sealed air, solve the oil pump into the air without oil and the resulting series lubrication problems. After several years of use there is no problem because the pump affect the host normal production, improve the operating rate of the cone crusher, but also extend pump life and reduce the amount of maintenance.

5, the tapered bushing. August 1997 PYD-2200 type cone crusher body strong vibration, no-load dynamic cone significantly increased the number of rotations. Hanging out examination revealed catchy vertically downward taper bushing copper opened 110mm long crack. Spindle with taper bushing hole gap is too small. For the above, the first pair of tapered bushing bore scraping, the upper portion of the main shaft with the tapered bushing gap is 3. 5mm, lower clearance 8. 5mm and then in the middle of the inner wall of the conical bush and the lower end of each crack drill a 5mm holes, to eliminate the stress, as shown. By repairing the scrapped so that the tapered copper jacket, has been used for nearly 3a, after repeated examination, the crack did not continue to extend the shaft and sleeve hole gap is still within the specified range, the crusher is operating normally.
