When it comes to maintaining aggregate equipment, you need to keep up with your routine inspections and service. Cone crushers are no exception to this. Many of the minor performance issues that you might experience with a cone crusher can be avoided through the practice of routine cleaning and upkeep. Here's a look at some of the things that should be staples in your daily maintenance schedule.
Monitor the Feed Rate
Keep the machine choke fed while it's operating. This will help you get the most out of the crushing process. By controlling this process, you can regulate the final product shape for more consistency. When the system is feeding too slowly, it will lead to damage inside the machine from the crushing force pushing back into the crusher.
If you feed the crusher too quickly, the rushed process may lead to damaged components and premature wear inside the machine. You may also face an increase in recirculating to get the texture that you need, which can damage the screens.
Maintain the Oil Lubrication System
Oil changes are an important part of the routine as well. The crusher uses oil for many things, including lubricating the moving components and keeping the system cool. Changing the oil regularly will ensure that the oil is clean. Contaminated or degraded oil can actually cause the bearings to wear prematurely.
Check the oil filters on a daily basis so that you can spot the signs of oil wear or contamination. Change the filters regularly as recommended by the equipment manufacturer. If you do find contaminants in your oil, it's in your best interest to not only change the oil and replace your filter, but also to find the source of the contaminants.
If you have a hydraulic leak, for example, you'll face repeated oil contamination until you fix the leak. Inspect the system thoroughly and repair the source of the problem before you restore the normal function.
Check the oil pump shaft for any signs of a leaking seal. You may see some drips of oil from this seal when it's operating, but if there's more than just the occasional small drip each minute or so, you may want to replace the seal.
Inspect the Cooling System
Cone crushers often feature either an air or water cooler to help support the oil in keeping the system functioning at a proper temperature. If your system has an air cooler, you'll need to keep the fins clean and clear of debris. Wipe the blades down on a regular basis so that you don't introduce any particles or debris to the system.
If your system is water-cooled, it needs other care. You'll need to drain the water cooler before the cold weather arrives. If you leave water in the cooling system during the winter, it is likely to freeze, which can damage the system. Once you drain the water lines, you should have a contractor blow out the lines to make sure there's no debris or buildup in it.
Check the Main Frame for Damage
You'll want to check the main frame for any physical damage. If the bore is nicked, scored or burred, you'll want to remove the damage. Use a fine-grade file or an emery cloth to do this. The goal is to make sure there's no damage that could cause abrasion inside the system. If you can't get the parts smooth, you may want to break the equipment down and use a machine-driven file or grinder to clean it up.
By following the tips presented here, you can keep your cone crusher running at its best at all times. If you buy a used crusher at auction or from a company like Machinery Access, make sure that you go through this process before you put it into production. This will give you the confidence that your equipment is safe for full-scale production.Share
