proper crusher lubrication - tip of the week - lube talk - mobil connect

Jaw crushers: In jaw crushers, a large feed opening receives material. There are two outer bearings located on either side of the main frame to support an eccentric shaft. There are also two inner bearings known as pitman bearings that support a moveable jaw. The reciprocating motion of the shaft moves the pitman against stationary jaw and as material reaches the bottom of the chamber, it fractures. Jaw crushers typically use spherical roller bearings, which support radial loads and misalignment. These bearings also operate under moderate speeds and loads, with occasional load spikes.

Cone gyratory crushers: In a cone crusher, the main shaft is housed in a frame attached to a mantle. A pinion shaft assembly drives a bevel gear that rotates the cone. As material presses against the bowl, it is crushed into smaller pieces. Cone crushers have two radial and two axial bearings. The radial bearings are cylindrical roller bearing, while the axial bearings are tapered thrust and cylindrical thrust bearings. These bearings operate at moderate speeds but support heavy loads as well as occasional shock loads.

Impact hammer crushers: Hammer mills are typically used as secondary crushing. They have high rotational speeds with variable loading conditions and use spherical roller bearings to handle radial loads and shaft misalignment. These bearings are of split pillow block design and provide support during crusher operation.

Oils: As a general rule, operators should use extreme pressure fortified gear lubricants with a minimum viscosity of 22 cSt at the bearing operating temperature. This typically demands an AGMA 3 EP or 4 EP gear oil. The lube oil should operate in a range between 10 and 50 degrees Celsius. Operators should also implement a routine oil sampling program to effectively monitor oil and crusher condition, as the demanding operating conditions of this equipment can lead to sudden changes in performance.

Greases: Operators should look for lithium or calcium soap-based greases that have a base oil viscosity of ISO 220 to 460 and that contain extreme pressure additives. In some cases, operators may use greases that contain a molybdenum disulfide additive to protect against adhesive wear. Most crusher bearings should be frequently re-greased to ensure proper lubrication and the purging of external contamination.

Hi Rick, We have double Toggle Crusher with pitman bearing. Currently the temperature quite hugh (74 deg,C) and they run with MObilith SHC 220. Do YOu have simple EHL calculation just to ensure the MObilith SHC 220 is enough and support this bearing.

Does Anyone has an experience using mobil centaur xhp 462 on crusher/vibrating screen applications?Which has better performance between Mobilgrease XHP 462 or Mobil Centaur XHP 462 for Crusher or Vibrating Screen Applications on Quarry?

Thanks and very useful information. In Jaw crushers bearing lubrication We use Mobilith SHC 007 NLGI 00 VG 460 .The grease perform well as compare to other competitor greases. We had bearing failures more on outer Main bearings than pitman bearings due to contamination with metal dust.

My Question is , Here in Jaw crushers , Under greasing is a main issue and jaw bearing reduce performance and lead to serious damage. For manual greasing it is very difficult to monitor the running hr and monitor the temp. So any recommendation to overcome such issues.

Jose - the grease lubricated crusher is usually serviced twice in an 8 hour shift. This is necessary to remove contaminants that enter during the crushing process. Techniques to verify if your lubricant is effective is to look at the failed parts to determine mode of failure and to measure bearing life versus that predicted by the OEM.

gyratory crusher lubrication

gyratory crusher lubrication

The lubrication of Gyratory crushers may be one of the special problems that the Jaw crusher isnt as readily exposed to. This crusher, because it may be loaded from two sides, often is used in an open pit situation where large ore carriers are dumping directly into the crusher. This means that the machinery is exposed to whatever climate it is being operated in. In hot areas the oil may have to be cooled while the opposite is true for the colder climates. The oil temperature must be kept moderate so that it will provide the necessary cooling as well as warm enough to be easily pumped through the oil system. (not specificallygyratory spider grease).

In most of the modern crushers, instrumentation has been included in their design to provide control over the temperature range of the oil. If the temperature should exceed either the low or high set point then the crusher will automatically shut down. To aid in the cooling a large volume of oil is constantly circulated, by pump, through the oil system. Because of this volume and because it may have to be heated in cold climates, an external holding tank or reservoir is used. To .heat the oil a submersible heating unit will be placed inside this tank.

Now lets see what this oil lubricates. From the holding tank the oil will be pumped through filters to take out any solids that may be accumulating in the oil. From the filters the oil goes to the drive assembly to lubricate the pinion gear, the thrust bearing, eccentric bushing, as well as the eccentric itself from there it returns to the reservoir.

You notice that the oil doesnt lubricate the Spider bearing. This bearing is normally greased instead. You will notice the different types of alloys and surfaces that have to be lubricated, the pinion and crown gear, the alloys of the bronze thrust bearings and the eccentric which is made from Babbitts Metal. It is very important for these metals that the right type of oil or grease be used as a lubricant. In fact most manufacturers guarantees are void if the wrong oil is used.

I would like to put a foot note in here on thrust bearings, the name thrust bearing is not so much the type of bearing but the job that it does. As an example, the thrust bearing in a crusher is two flat pieces of metal with oil channels in between them. They support the weight of the mantle as well as provide an anti-friction surface for the rotation of the mantle.

There is another thrust bearing that looks very much like an ordinary roller hearing. The difference is the race and the cage of this hearing is heavier, with the hearings themselves sitting deeper into the race.

Lets get hack to our oil system. The reservoir is the area that the operator will give the most of his attention to when he does his circuit checks. It is here that problems with the system will he discovered. At the reservoir there will be gauges to indicate TEMPERATURE and LINE PRESSURE. These of course indicate any fluctuation of the oil temperature or pressure. A change in either of these could mean that a hearing is worn out, the oil level is to low, oil flow low, or perhaps dirty oil. If the crusher is fitted with a water line to cool the oil, it may be restricted or shut off.

A simple progressive system consists of a pump and a distributor block. The distributor block (called as progressive block) will dispense the lubricant in measured amount directly in the lube points through the feed lines. The visual indicator pin on the progressive block confirms the delivery of lubricant. The pin moves in and out in each cycle of the lubricant delivery.

The complete system can be automated by incorporating a controller. The pump will be activated at regular intervals for fixed number of lubrication cycles while the production machine is in operation.Progressive Block will dispense small measured amounts of lubricant in each and every cycle. Progressive Systems are used for continuous as well as time based intermittent lubrication.

Applications: steel plants, paper plants, heavy-duty power presses, printing machines, textile machines, packaging machines, metal working, material handling equipments, injection moulding machines, mobile equipments, chassis lubrication etc.

These systems provide the lubrication points with grease using the little and often approach, where a small amount of grease is delivered at regular intervals ensures a lubricant film is always maintained therefore minimising friction and wear.

Multiline Lubricator is a user-friendly and cost-effective solution for centralized and automatic lubrication of a machine or equipment having multiple points. Multiline lubricator combines multiple pumps into a single entity sharing a common reservoir and common drive. They are very simple in design and require little maintenance. These types of lubricators are fitted on a machine suitably and are connected to the lubrication points by means of welded/seamless steel tubes, rubber hoses, and compression type fittings & clamps.

The main element of various Multipoint Lubricators is pumping unitsone for each point. The plunger of each pumping unit is given a reciprocating motion with the help of a cam. The cam itself rotates at suitable RPM by any machine shaft or with the help of an electric motor and a gearbox. For grease lubricators, a deflector/ stirrer also rotate with a cam. The helps in creating the positive suction of great and minimizes air trapping.

Jaw crusher is a commonly used crusher equipment. We all know that its working environment and material characteristics have a certain impact on the service life of the equipment. Therefore, the maintenance work during the operation of the jaw crusher must be carried out in strict accordance with the operation process, so that its life can be longer. Jaw crusher is the primary crushing equipment for various ores, so operators are required to have good operating capabilities. At work, how to choose to add grease is an important operation, which is one of the things that operators must pay attention to.

Jaw crusher equipment works in different environments and requires different lubricants. In the summer, the outdoor temperature is relatively high, so you can use the No. 70 mechanical oil, while the outdoor temperature in winter is low. When the jaw crusher needs continuous work, there is a heating device in winter, which can preheat the lubricating oil. When the ambient temperature is not too high in summer, you can use the No. 50 oil as the lubricating oil.

Since the large and medium jaw crusher bearings and the eccentric shaft are pressure cycle lubrication, when the oil pump fails, the jaw crusher needs to swing the power for 15-20 minutes to stop, so it is necessary to press the oil pump to apply oil to the bearing. Keeping it lubricated, there is no accident of burning the bearing.

The jaw crusher has different lubrication points, and its lubrication requirements are different, and there are differences in terms of time. For example, the jaw crusher's dynamic suspension shaft bearing and the thrust plate elbow are lubricated without oil return, so intermittent grease is required. The bearing of the small jaw-type crushing motorized suspension shaft adopts the oil cup and lubricating oil, so it can be used once in 30-40min. The elbow of the thrust plate is lubricated with thick oil and needs to be lubricated every 3-4h.

There is also the temperature of the jaw crusher lubricant, we must also pay attention. In the use of the jaw crusher thin oil system, the temperature of the oil return should not exceed 60 degrees. When the temperature is too high, we need to adjust the oil flow by adjusting the oil valve or use water cooling to reduce the temperature. This will ensure the work of its production. https://www.hxcrusher.com/blog/cause-analysis-and-troubleshooting-of-jaw-crusher/

Just like other stone crusher machines, jaw crusher also needs a regular repair and maintenance after a certain time of working, or it will get decreased service life because of severe wear of important parts.

So many customers have common misconception that jaw plates only need repair when appearing flat, holes, cracks. Actually if jaw plates wears badly, it is not only hard to repair but seriously affects the normal working of other parts, which then will take a great sum of money to change a jaw plate and maintain other parts.

The pitman drives the moveable jaw dies to push stone material towards stationary jaws, which would create strong pressing forces to both jaw dies. Therefore, if the pitman cannot get lubrication in time, it will be broken under the high pressure of material and interrupt the whole work.

Proper plan and preparation make the whole repair and maintenance ordered and effective, which helps operators save time, cost, and enhance their safety. You can make a checklist just like the following chart in which you can list need-checked jaw crusher parts with a different period then making a mark if you are done with them. This not only prevents missed inspections, but also makes the arrangement clear, and saves a lot of time.

The lubrication of the interface between the parts of the jaw crusher is very important. It can minimize the friction generated during the operation, make the whole jaw crusher run smoothly, and extend its service life.

Unlike gyratory crushers, the main lubrication used in jaw crushers is grease instead of oil. When using grease, there may be several different ways to inject it into the necessary lubrication points. It can be operated manually with a grease gun, an oiler or metering pump.

Eccentric shaft (pitman bearing): It is behind the moveable jaw plate, and together with flywheel with toggle plate to create a motion. So, the most important thing you must do is keeping a regular lubrication to eccentric shaft, or you will spend more than four hours in changing a new one when it is broken.

Main shaft To keep the main shaft in good lubricating situation, you need to guarantee enough geese between thrust plate.The grease added to the bearing box needs to occupy about 50% of its space and be replaced every 3-6 months. When changing the engine oil, please use clean gasoline or kerosene to clean the roller bearing raceways.

There are different jaw plates material in the market, and some of them suits for hard stone while other is not. Therefore, you have to choose the right jaw plate for your crusher. For example, generally the jaw plate of single toggle jaw crusher is not good at crushing strongly abrasive and hard stone material with large production.

The function of toggle plate is to adjust the outlet of the jaw crusher to the desired size. There are two specific methods: one is to replace the support pad between the toggle plate and the body frame, and the other is to adjust the two wedges between the toggle and the body frame.

Fote Company has more than 40-year manufacturing experience, mainly engineering different types of jaw crushers including PE jaw crusher, Dodge jaw crusher, Blake type jaw crusher(double toggle jaw crushers), single toggle jaw cruhser, etc., and all of them can be customized.

All Lippmann heavy-duty jaw crushers feature an oversized, heat treated shaft forged of special alloy to provide an exceptionally large eccentric throw. These heavy-duty shafts are paired with two dynamically balanced flywheels, effectively reducing vibration on both portable and stationary crushers. The overhead eccentric configuration does not rely on gravity alone to move material through the chamber. Rather, the inward and downward movement of the swing jaw provides for a forced-feeding motion to maximize output. All shafts are machined and put through a rigorous inspection process before they enter production.

In order to optimize bearing life, only tapered roller bearings are used in Lippmann jaw crushers. The tapered bearings offer a combination of features that spherical bearings are unable to provide. When considering the adjustable clearance, line contact, true rolling motion and ability to carry both radial and thrust loads, the tapered roller bearing is an obvious choice for all jaw crushers. Lippmann proudly stocks a large inventory of all bearing sizes.

The automatic hydraulic toggle has greatly reduced the time it takes to change a jaw crushers setting. As jaw dies wear, the hydraulic toggle can be easily adjusted to maintain a constant closed side setting while in continuous operation. An added benefit of the Lippmann hydraulic toggle package is the ability to provide tramp release once an un-crushable has entered the crushing chamber. Nitrogen-powered automatic hydraulic toggles are available on all mid-sized to large model jaw crushers.
