Three Steps To Keeping Your Cone Crusher's Lubrication System Healthy

Since a mining operation relies so heavily on the crushing of ore, the maintenance of its crushing machines is central to a consistent daily routine; and without an effective lubrication system, which is used not only to lubricate but to cool as well, crushing machines will crush no ore. Here are three vital steps to optimally maintaining the healthy lubrication system your cone crusher needs.

1. Use the best oil changing techniques.

Just like your car, your cone crusher can suffer if its oil becomes dirty or too old, so of course you should check oil filters daily and change the oil after a certain amount of run time (ideally six hundred hours). But equally important is the way in which you change the oil. Dust and water, both common contaminants, have easy access to the lubrication system when the oil tank is open. Because of this, it's very important to make sure that the machine is immobilized, level, and clean before you start. Always use a damp cloth to wipe dust off your machine before opening its tank. In addition, avoid changing oil in the rain.

2. Keep records.

Scheduled oil sampling is a good idea for most machines and essential for cone crushers. If you keep track of the condition of the oil in each machine over a long period of operation, you can track its deterioration between oil changes. After you form a reasonable expectation of what the oil will be like at any point during its life, you can start to check samples against this expectation. When one particular sample diverges drastically from the norm, you'll know you need to investigate. Maybe you got a bad batch of oil, maybe the oil changing procedure was sloppy, or maybe an oil leak is allowing an intrusion of dust into the system. If you catch oil contamination immediately, it won't have a chance to shorten your machine's life by putting undue stress on your machine's gears and bearings. 

3. Choose the ideal oil.

Your manufacturer recommended oil is the first choice when you begin operations, but sometimes special circumstances require a change. Since your cone crusher uses oil for cooling as well as for lubrication, oil temperature must be taken into consideration. For example, if your machine usually operates in an extremely hot or extremely cold environment, it may be difficult to keep the oil between 50 degrees Fahrenheit and about 125 degrees (the recommended optimum temperature). In this situation a synthetic oil, such as a synthetic hydrocarbon or a polyalkaline glycol (PAG) base oil, may be a better solution. These types of oil are more thermally stable, so they're better at standing up to adverse climate conditions, such as extremely hot weather.

When machinery is an essential part of your company, technical difficulties can easily cause unwanted downtime. You can minimize unplanned repair downtime by using these three steps to optimize your cone crusher's lubrication maintenance and keep the machine, and your mining operations, running smoothly.
